NOTE
• When both the forward rotation start switch (STF signal) and the reverse rotation start switch (STR signal) are turned ON, the
motor cannot be started. If both are turned ON while the inverter is running, the inverter decelerates to a stop.
• The initial value is 60 Hz for terminal RH in Group 1 (50 Hz in Group 2), 30 Hz for terminal RM, and 10 Hz for terminal RL. (To
change the settings, use Pr.4, Pr.5, and Pr.6, respectively.)
• In the initial setting, if two or more speed switches (signals) are simultaneously turned ON, priority is given to the switch (signal)
for the lower speed. For example, when both RH and RM signals turn ON, the RM signal (Pr.5) has the higher priority.
• Up to 15-speed switching operation can be performed.
• Up to two external input terminals are available for the Ethernet model and the IP67 model. Use Pr.178 STF/DI0 terminal
function selection and Pr.179 STR/DI1 terminal function selection to assign the functions to terminals DI0 and DI1.

 3.3 Use of a function group number for the
identification of parameters
A parameter identification number shown on the PU can be switched from a parameter number to a function group number.
As parameters are grouped by function and displayed by the group, the related parameters can be set continually at a time.

 Changing a parameter identification number to a function group number

Pr.MD setting Description
0 The setting of parameter identification number remains the same as the last setting.
1 The parameter number is used for the identification of parameters, and displayed in numerical order.
2 The function group number is used for the identification of parameters, and displayed in alphanumeric order.

Operating procedure
1. Turning ON the power of the inverter
The operation panel is in the monitor mode.

2. Selecting the parameter setting mode

Press the MODE key to choose the parameter setting mode. (The parameter number read previously appears on
the 12-segment LCD display.)

3. Selecting a parameter
Turn the setting dial or press the UP/DOWN key until "Pr.MD" (Group parameter setting) appears.

 4 Control Method
V/F control (initial setting), Advanced magnetic flux vector control, Real sensorless vector control, Vector control, and PM
sensorless vector control are available with this inverter.

 V/F control
The inverter controls the output frequency (F) and the output voltage (V) so that the ratio of frequency to voltage (V/F) is kept
constant when the frequency is changed.

 Advanced magnetic flux vector control

The inverter performs vector calculation and divide its output current into the excitation current and the torque current. The
inverter compensates the frequency and the voltage to output a current that meets the load torque to the motor, which improves
the motor torque at low speed. The output frequency is further compensated (slip compensation) to bring the actual motor
speed closer to the commanded speed. This control method is useful when the load fluctuates are severe.

NOTE
• Advanced magnetic flux vector control requires the following conditions.
If these conditions are not satisfied, select V/F control. Otherwise, malfunctions such as insufficient torque, uneven rotation
may occur.
• The motor capacity must be the same or one rank lower than the inverter capacity.
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque accuracies
may deteriorate due to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter rated current. (For
details on the inverter rated current, refer to the inverter rated specifications in the Instruction Manual (Connection).)
• The motor described in the following table is used.

Motor Condition
Mitsubishi Electric standard efficiency motor (SF-JR)
Mitsubishi Electric high-efficiency motor (SF-HR)
Mitsubishi Electric constant-torque motor (SF-JRCA 4P, SF-HRCA) Offline auto tuning is not required.
Mitsubishi Electric high-performance energy-saving motor (SF-PR)
Mitsubishi Electric geared motor (constant-torque) (GM-[])
Other motors (other manufactures' motors) Offline auto tuning is required.
• Single-motor operation (one motor to one inverter) is performed.
• The wiring length from the inverter to the motor is 30 m or less. (When the wiring length exceeds 30 m, perform offline auto
tuning with the wiring in place.)

 Real sensorless vector control

• As the inverter estimates the motor speed and controls the output current more accurately, a high-level control of the speed
and the torque is enabled. Select Real sensorless vector control for a high-accuracy, fast-response control. The offline auto
tuning is required initially.
• This control method is useful for the following purposes:
- To minimize the speed fluctuation even at a severe load fluctuation
- To generate a low speed torque
- To prevent machine from damage due to a too large torque (To set the torque limit)
- To control the torque

108 4. Control Method

 NOTE
• Real sensorless vector control requires the following conditions. 1
If these conditions are not satisfied, select V/F control. Otherwise, malfunctions such as insufficient torque, uneven rotation
may occur.
• The rated motor current should be equal to or less than the inverter rated current.
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque accuracies
2
may deteriorate due to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter rated current. (For
details on the inverter rated current, refer to the inverter rated specifications in the Instruction Manual (Connection).)
• Offline auto tuning is performed. 3
Offline auto tuning is required under Real sensorless vector control even when the Mitsubishi Electric motor is used since the
wiring length affects the operation.
• Single-motor operation (one motor to one inverter) is performed.
• A surge voltage suppression filter (FR-ASF/FR-BMF) is not used. 4

 Vector control 5
• With a vector control option (FR-A8AP E kit) installed, full-scale vector control operation of a motor with an encoder can
be performed. Speed control (zero speed control, servo lock), torque control, and position control can be performed with
fast response and high accuracy. Vector control is not available for the IP67 model as plug-in options are not available. 6
• Vector control has excellent control characteristic compared to other control methods such as V/F control. Its control
characteristic is equal to those of DC machines.
• This control method is useful for the following purposes:
7
- To minimize the speed fluctuation even at a severe load fluctuation
- To generate a low speed torque
- To prevent machine from damage due to a too large torque (To set the torque limit)
- To control the torque or position
8
- To control a torque generated in a motor in a servo-lock state (the motor with its shaft stopped)

10

4. Control Method
109
 NOTE
• A vector control option (FR-A8AP E kit) needs to be installed to perform Vector control. The FR-A8AP E kit cannot be used
with another plug-in option, as two or more plug-in options cannot be installed to the FR-E800 inverter at the same time.
• Vector control requires the following conditions.
When the conditions are not satisfied, malfunctions such as insufficient torque, uneven rotation may occur.
• The rated motor current should be equal to or less than the inverter rated current.
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque accuracies
may deteriorate due to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter rated current. (For
details on the inverter rated current, refer to the inverter rated specifications in the Instruction Manual (Connection).)
• An induction motor is used. (Vector control is not available for a PM (IPM/SPM) motor.)
• The motor described in the following table is used.

The offline auto tuning is required.
Other motors (motors other than SF-V5RU 1500 r/min series, other
manufactures' motors, etc.)

• Single-motor operation (one motor to one inverter) is performed.

• The wiring length from the inverter to the motor is 30 m or less. (When the wiring length exceeds 30 m, perform offline auto
tuning with the wiring in place.)
• A surge voltage suppression filter (FR-ASF/FR-BMF) is not used.

 PM sensorless vector control

• The inverter enables highly efficient motor control and highly accurate motor speed control of a PM (permanent magnet
embedded) motor, which is more efficient than an induction motor.
• A speed detector such as an encoder is not required as the inverter estimates the motor speed by the calculation from the
inverter output voltage and current. The inverter drives the PM motor with the least required current for a load in order to
achieve the highest motor efficiency.
• When a PM motor (MM-GKR or EM-A) is used, just performing PM parameter initialization enables PM sensorless vector
control.

 4.1 Vector control and Real sensorless vector control
Vector control is one of the control techniques for driving an induction motor. To help explain Vector control, the fundamental
equivalent circuit of an induction motor is shown below.
r1: Primary resistance
r2: Secondary resistance
1: Primary leakage inductance
im
r1
2: Secondary leakage inductance
1 2

M: Mutual inductance
S: Slip
r2
id M iq
S id: Excitation current
iq: Torque current
im: Motor current

In the above diagram, currents flowing in the induction motor can be classified into a current id (excitation current) for making
a magnetic flux in the motor and a current iq (torque current) for causing the motor to develop torque.

In Vector control, the voltage and output frequency are calculated to control the motor so that the excitation current and torque
current flow to the optimum as described below:

iq motor current im
torque current

excitation current
id

• The excitation current is controlled to place the internal magnetic flux of the motor in the optimum status.
• The torque command value is derived so that the difference between the motor speed command and the actual speed
(speed estimated value for Real sensorless vector control) obtained from the encoder connected to the motor shaft is zero.
Torque current is controlled so that torque as set in the torque command is developed.

Motor-generated torque (TM), slip angular velocity (ωs) and the motor's secondary magnetic flux (Φ2) can be found by the
following calculation:
TM Φ2 · iq
Φ2 = M · id

iq
ωs = r2
L2 id
where, L2: secondary inductance
L2 = 2 + M

Vector control provides the following advantages:

• Vector control has excellent control characteristic compared to V/F control and other controls. The control characteristic of
the Vector control is equal to those of DC machines.

4.1 Vector control and Real sensorless vector control

Speed control operation is performed to zero the difference between the speed command (ω*) and actual rotation value
Speed control detected by encoder (ωFB). At this time, the motor load is found and its result is transferred to the torque current
controller as a torque current command (iq*).
Torque current A voltage (Vq) is calculated to flow a current (iq) which is identical to the torque current command (iq*) found by the
control speed controller.
Magnetic flux The magnetic flux (Φ2) of the motor is derived from the excitation current (id). The excitation current command (id*) is
control calculated to use that motor magnetic flux (Ф2) as a predetermined magnetic flux.
Excitation current A voltage (Vd) is calculated to flow a current (id) which is identical to the excitation current command (id*).
control
Output frequency Motor slip (ωs) is calculated on the basis of the torque current value (iq) and magnetic flux (Φ2). The output frequency
calculation (ω0) is found by adding that slip (ωs) to the feedback (ωFB) found by a feedback from the encoder.
The above results are used to make PWM modulation and run the motor.

4.2 Changing the control method and mode
 Changing the control method with external terminals (RT signal, X18
signal)
1
• Control method (V/F control, Advanced magnetic flux vector control, Real sensorless vector control, Vector control) can
be switched using external terminals.
2
The control method can be switched using either the Second function selection (RT) signal or the V/F switchover (X18)
signal.
• Set the second motor in Pr.450 Second applied motor and set the second motor's control method in Pr.451 Second
motor control method selection. Turning ON the RT signal or X18 signal enables the second function, enabling the
3
switchover of the control method.
• To input the RT signal, set "3" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function.
4
To input the X18 signal, set "18" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.

NOTE
• The RT signal is a second function selection signal. The RT signal also enables other second functions. (Refer to page 418.)
• When V/F control is set using the V/F switchover (X18) signal, the second functions are selected at the same time.
• The control method could be changed by external terminals (RT signal, X18 signal) while the inverter is stopped. If a signal is
switched during the operation, the control method changes after the inverter stops.

4. Control Method
4.2 Changing the control method and mode
119
  Changing the control mode with external terminals (MC signal)
• The setting of Pr.800 or Pr.451 can be used to switch the control mode by turning ON/OFF the MC signal. Refer to page
116 to set Pr.800 or Pr.451.
To input the MC signal, set "26" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.
• When using an analog input terminal (terminal 4) for torque limit and torque command, switching of the control mode
changes the terminal function as follows:

NOTE
• Switching between the speed control and the torque control is always enabled regardless of the motor status: in a stop, in
running, or in DC injection brake (during pre-excitation).
• During operation, the control mode is switched between speed control and position control or between torque control and
position control when the output frequency reaches Pr.865 Low speed detection or lower with no position command given.
Switching is disabled when either of the following signals is ON: Sudden stop (X87) signal (normally open input), Forward
stroke end (LSP) signal (normally open input), or Reverse stroke end (LSN) signal (normally open input).
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

NOTE
• To perform driving in a better accuracy, perform offline auto tuning, then set the online auto tuning, and select Real sensorless
vector control.
• Under this control, rotations are more likely to be uneven than under V/F control. (This control method is not suitable for
grinder, wrapping machine, etc., which require even rotation at a low speed.)
• When the inverter is operated with a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) installed between the inverter

parameter initialization, and using PM parameter initialization ("PM").

 Initializing the parameters required for the PM sensorless vector control 3

(Pr.998)
• Use PM parameter initialization to set the parameters required for driving a PM motor.
• The offline auto tuning enables the operation with a PM motor other than the MM-GKR or EM-A. (Refer to page 430.) 4
• All the parameters required for PM motor control are automatically set by setting Pr.998 ≠ "0".

The FR-E820-0080(1.5K) or lower, the FR-E820S-0080(1.5K) or lower, or FR-E810W-0050(0.75K) or lower is used and Pr.80 ≤ 0.75 kW.
The FR-E820-0050(0.75K) or lower, the FR-E820S-0050(0.75K) or lower, or FR-E810W-0050(0.75K) or lower is used and Pr.80 = "9999".

The FR-E820-0470(11K) or lower is used and Pr.80 ≤ 7.5 kW.
The FR-E820-0330(7.5K) or lower is used and Pr.80 = "9999".
The FR-E840-0230(11K) or lower is used and Pr.80 = 0.4 to 7.5 kW.
The FR-E840-0170(7.5K) or lower is used and Pr.80 = "9999".
The FR-E820S-0110(2.2K) or lower is used and Pr.80 ≤ 2.2 kW.
The FR-E820S-0110(2.2K) or lower is used and Pr.80 = "9999".
The FR-E810W-0050(0.75K) or lower is used and Pr.80 ≤ 0.75 kW.
The FR-E810W-0050(0.75K) or lower is used and Pr.80 = "9999".
The FR-E846-0095(3.7K) or lower is used and Pr.80 = 2.2 or 3.7 kW.
The FR-E846-0060(2.2K) or FR-E846-0095(3.7K) is used and Pr.80 = "9999".

• To use a motor capacity that is one rank lower than the inverter capacity, set Pr.80 Motor capacity before performing PM
parameter initialization.
• When "3024, 3044, 8009, or 9009" is set in Pr.998, the motor speed which was set/monitored in frequencies is set/
monitored in motor rotations per minute. To set/monitor in frequencies, set "3124, 3144, 8109, or 9109" in Pr.998.
• Set Pr.998 = "0" to change the PM sensorless vector control parameter settings to the parameter settings required to drive
an induction motor.
• When using a PM motor other than the MM-GKR or EM-A, set "8009, 8109, 9009, or 9109" in Pr.998.

4. Control Method
4.4 Selecting the PM sensorless vector control
123
 NOTE
• Make sure to set Pr.998 before setting other parameters. If the Pr.998 setting is changed after setting other parameters, some
of those parameters are initialized too. (Refer to the "List of the target parameters for the motor parameter initialization".)
• To change back to the parameter settings required to drive an induction motor, perform Parameter clear or All parameter clear.
• Whenever the setting of Pr.998 PM parameter initialization is changed from "3024, 3044, 8009, or 9009 (rotations per
minute)" to "3124, 3144, 8109, or 9109 (frequency)", and vice versa, all the relevant parameters are initialized.
The purpose of Pr.998 is not to change the display units. Use Pr.53 Frequency / rotation speed unit switchover to change
the display units between rotations per minute and frequency. Using Pr.53 enables switching the unit between rotations per
minute and frequencies without initializing the setting of the motor parameters.
• The PM parameter initialization (Pr.998) changes parameter settings for the first motor. When a PM motor is used as the
second motor, parameters for the second motor must be set individually.

 List of the target parameters for the motor parameter initialization

• The settings of the parameters in the following table are changed to the settings for PM sensorless vector control by
performing the motor parameter initialization using Pr.998 PM parameter initialization. The changed settings differ
according to the specification (capacity) of the PM motor used.
• Performing Parameter clear or All parameter clear resets these parameter settings to the settings required to drive an
induction motor.

3. Set the overheat protection of the motor (Pr.9). (Refer to page 306.)

4. Set the motor capacity and number of motor poles (Pr.80, Pr.81). (Refer to page 115.) 5
Operation does not start when the setting value is "9999" (initial value).

5. Set the rated motor voltage and the rated motor frequency (Pr.83, Pr.84). (Refer to page 430.)
6
6. Select the control method (Pr.800). (Refer to page 115.)
Select Pr.800 = "10" (speed control) or "12" (speed/torque switchover) to enable speed control.

7. Set the operation command. (Refer to page 280.) 7

Select the start command and speed command.

8. Set the torque limit (Pr.810). (Refer to page 139.) 8

9. Perform the offline auto tuning (Pr.96). (Refer to page 430.)
10. Perform the test operation.
9
As required
• Select online auto tuning (Pr.95). (Refer to page 449.)
• Adjust the speed control gain manually. (Refer to page 146.)
10
NOTE
• During Real sensorless vector control, offline auto tuning must be performed properly before starting operations.
• The speed command setting range under Real sensorless vector control is 0 to 400 Hz.
• The carrier frequency is limited during Real sensorless vector control. (Refer to page 249.)
• Torque control is not available in a low-speed (about 10 Hz or lower) regenerative range, or with a low speed and light load
(about 5 Hz or lower and rated torque about 20% or lower). Vector control must be selected.
• Performing pre-excitation (LX signal and X13 signal) under torque control may start the motor running at a low speed even
when the start signal (STF or STR) is not input. This product with the start command ON may also rotate the motor at a low
speed when the speed limit value is set to zero. Confirm that the motor running does not cause any safety problems before
performing pre-excitation.
• Switching between the forward rotation command (STF) and reverse rotation command (STR) must not be performed during
operations under torque control. An overcurrent trip (E.OC[]) or opposite rotation deceleration fault (E.11) will occur.
• In case of starting the motor while the motor is coasting under Real sensorless vector control, the frequency search must be
set for the automatic restart after instantaneous power failure function (Pr.57 ≠ "9999", Pr.162 = "10"). (Refer to page 502.)
• When Real sensorless vector control is applied, there may not be enough torque provided in the ultra low-speed range of about
2 Hz or lower.
Generally, the speed control range is as follows.
For power driving, 1:200 (2, 4 or 6 poles) (available at 0.3 Hz or higher when the rating is 60 Hz), 1:30 (8 or 10 poles) (available
at 2 Hz or higher when the rating is 60 Hz).
For regenerative driving, 1:12 (2 to 10 poles) (available at 5 Hz or higher when the rating is 60 Hz).

5. Set the rated motor voltage and the rated motor frequency (Pr.83, Pr.84). (Refer to page 430.)

6. Select the control method (Pr.800). (Refer to page 115.)

Select Pr.800 = "0" (speed control), "2" (speed/torque switchover), or "4" (speed/position switchover) to enable
speed control.

7. Set the operation command. (Refer to page 280.)

Select the start command and speed command.

8. Set the torque limit (Pr.810). (Refer to page 139.)

9. Perform the test operation.

As required
• Perform offline auto tuning (Pr.96). (Refer to page 430.)
• Select online auto tuning (Pr.95). (Refer to page 449.)

NOTE
• Under Vector control, the magnetic flux observer is enabled to estimate or measure the flux within the motor using the current
running through the motor and the inverter output voltage. This improves the torque accuracy since the flux of a motor can be
accurately estimated and optimum characteristics can be obtained without being affected by temperature change in the
second resistor.
• The speed command setting range under Vector control is 0 to 400 Hz.
• The carrier frequency is limited during Vector control. (Refer to page 249.)
• Vector control is not available for the IP67 model as plug-in options are not available.

NOTE
• To change to the PM sensorless vector control, perform PM parameter initialization first. If parameter initialization is performed
after setting other parameters, some of those parameters are initialized too. (Refer to page 124 for the parameters that are
initialized.)
• The carrier frequency is limited during PM sensorless vector control. (Refer to page 249.)
• During PM sensorless vector control, the RUN signal is output about 100 ms after turning ON the start command (STF, STR).
The delay is due to the magnetic pole detection.
• When the wiring length from the inverter to the motor exceeds 30 m, perform offline auto tuning. (Refer to page 441.)

 Speed control gain adjustment

• The speed control gain can be adjusted for the conditions such as abnormal machine vibration, acoustic noise, slow
response, and overshoot.
• Setting 60% (initial value) in Pr.820 Speed control P gain 1 is equivalent to 120 rad/s (speed response of a single motor).
(Equivalent to the half the rad/s value during Real sensorless vector control.) Setting this parameter higher speeds up the
response, but setting this too high causes vibration and acoustic noise.
• Setting Pr.821 Speed control integral time 1 lower shortens the return time to the original speed during speed fluctuation,
but setting it too low causes overshoot.

• When the speed feed forward gain is 100%, the calculation result for speed feed forward is applied as is.
• If the speed command changes suddenly, the torque is increased by the speed feed forward calculation. The maximum
limit for the speed feed forward torque is set in Pr.879.
• The speed feed forward result can also be lessened with a primary delay filter in Pr.878.

 Speed deviation excess detection (Pr.285, Pr.853)

• When the automatic restart after instantaneous power failure function is selected (Pr.57 Restart coasting time ≠ "9999") and 1
the setting value for the number of encoder pulses is lower than the actual number of pulses, the output speed is limited with
the synchronous speed of the value of Pr.1 Maximum frequency + Pr.873.
• When a regenerative driving torque limit is applied and the speed limit function activates, the output torque may drop suddenly.
Also, when the speed limit function activates during pre-excitation operation, output phase loss (E.LF) may occur.
2
If the setting for the number of encoder pulses is confirmed as correct, it is recommended that Pr.873 be set to the maximum
value (400 Hz).
• Even if the set frequency is lowered after inverter operation, the speed limit value is not lowered. During deceleration, the 3
speed is limited at frequency command value + Pr.873.

 Deceleration check (Pr.690) 4

• This function can stop the inverter output when the motor is accelerated accidentally during rotation. This prevents a
malfunction due to incorrect encoder pulse settings.
• When the difference between the actual motor speed and the speed command value exceeds 2 Hz, the deceleration check 5

6.1 Torque control

This chapter explains the torque control under Real sensorless vector control or Vector control.
• Under torque control, output torque is controlled to output the torque as commanded.
• Motor rotation speed is steady when the motor output torque and load torque are balanced.
Thus, motor speed during torque control is determined by the load.
• Under torque control, motor speed accelerates so motor output torque does not exceed motor load.
In order to prevent the motor from overspeeding, set a speed limit.
(Speed control is performed instead of torque control during speed limit.)
• If speed limit is not set, speed limit value setting is regarded as 0 Hz and torque control is not enabled.

 • Speed control is performed when the actual speed exceeds the speed limit value.
• At the STF signal OFF, the speed limit value is lowered in accordance with the setting of Pr.8.
• Under torque control, the actual operation speed is a constant speed when the torque command and load torque are
balanced.
• The direction of motor torque generation is determined by a combination of the input torque command polarity and the start
signal, as given in the following table.

Polarity of torque Torque generation direction

Forward direction (forward power driving / reverse Reverse direction (forward regenerative driving /
+ torque command

Reverse direction (forward regenerative driving / reverse Forward direction (forward power driving / reverse

NOTE
• Once the speed limit is activated, speed control is performed and internal torque limit (Pr.22 Torque limit level) is enabled.
(Initial value) In this case, it may not be possible to return to torque control.
Torque limit should be external torque limit (terminal 4). (Refer to page 139.)
• Under torque control, perform linear acceleration/deceleration (Pr.29 = "0" (initial value)). When acceleration/deceleration
patterns other than the linear acceleration/deceleration are selected, the protective function of the inverter may be activated.
(Refer to page 267.)
• Performing pre-excitation (LX signal and X13 signal) under torque control may start the motor running at a low speed even
when the start signal (STF or STR) is not input. This product with the start command ON may also rotate the motor at a low
speed when the speed limit value is set to zero. Confirm that the motor running does not cause any safety problems before
performing pre-excitation.
• Under Real sensorless vector control, torque control is not available for regenerative driving in a low-speed range (about 10
Hz or lower) or light-load operation in a low-speed range (about 5 Hz or lower and about 20% or lower of the rated torque).

Set Pr.71 Applied motor to "0" (standard motor) or "10" (constant-torque motor). 4
3. Set the motor overheat protection (Pr.9). (Refer to page 306.)

4. Set the motor capacity and number of motor poles (Pr.80, Pr.81). (Refer to page 115.) 5
Operation does not start when the setting value is "9999" (initial value).

5. Set the rated motor voltage and frequency (Pr.83, Pr.84). (Refer to page 430.)
6
6. Select the control method (Pr.800). (Refer to page 115.)
Select Pr.800 Control method selection = "11" (torque control) or "12" (speed/torque switchover) to enable torque
control. 7
7. Set the torque command (Pr.804). (Refer to page 167.)
8. Set the speed limit (Pr.807). (Refer to page 171.) 8
9. Perform the offline auto tuning (Pr.96). (Refer to page 430.)
10. Set the acceleration time to "0" (Pr.7). (Refer to page 262.)

11. Perform the test operation.
As required 10
• Select online auto tuning (Pr.95). (Refer to page 449.)
• Adjust the torque control gain manually. (Refer to page 173.)

NOTE
• During Real sensorless vector control, offline auto tuning must be performed properly before starting operations.
• The carrier frequency is limited during Real sensorless vector control. (Refer to page 249.)
• Torque control is not available in a low-speed (about 10 Hz or lower) regenerative range, or with a low speed and light load
(about 5 Hz or lower and rated torque about 20% or lower).
• Performing pre-excitation (LX signal and X13 signal) under torque control may start the motor running at a low speed even
when the start signal (STF or STR) is not input. This product with the start command ON may also rotate the motor at a low
speed when the speed limit value is set to zero. Confirm that the motor running does not cause any safety problems before
performing pre-excitation.
• Switching between the forward rotation command (STF) and reverse rotation command (STR) must not be performed during
operations under torque control. An overcurrent trip (E.OC[]) or opposite rotation deceleration fault (E.11) will occur.
• If starting may occur while the motor is coasting under Real sensorless vector control, the frequency search must be set for
the automatic restart after instantaneous power failure function (Pr.57 ≠ "9999", Pr.162 = "10").
• When Real sensorless vector control is applied, there may not be enough torque provided in the ultra low-speed range of about
2 Hz or lower.
Generally, the speed control range is as follows.
For power driving, 1:200 (2, 4 or 6 poles) (available at 0.3 Hz or higher when the rating is 60 Hz), 1:30 (8 or 10 poles) (available
at 2 Hz or higher when the rating is 60 Hz).
For regenerative driving, 1:12 (2 to 10 poles) (available at 5 Hz or higher when the rating is 60 Hz).

• To give the constant torque command in the constant output range, set "1" in Pr.803 Constant output range torque
characteristic selection. (Refer to page 167.)
• For the settings for the SF-V5RU, refer to page 452.

3. Set the overheat protection of the motor (Pr.9). (Refer to page 306.)
When using the SF-V5RU or a motor equipped with a thermal sensor, set Pr.9 = 0 A. For details on connecting a
motor equipped with a thermal sensor, refer to the Instruction Manual (Connection).

4. Set the motor capacity and the number of motor poles (Pr.80, Pr.81). (Refer to page 115.)
V/F control is performed when the setting is "9999" (initial value).

Select Pr.800 Control method selection = "1" (torque control), "2" (speed/torque switchover), or "5" (position/
torque switchover) to enable torque control.

7. Set the torque command (Pr.804). (Refer to page 167.)

8. Set the speed limit (Pr.807). (Refer to page 171.)
9. Set the acceleration time to "0" (Pr.7). (Refer to page 262.)
10. Perform the test operation.
As required
• Perform offline auto tuning (Pr.96). (Refer to page 430.)
• Select online auto tuning (Pr.95). (Refer to page 449.)
• Adjust the torque control gain manually. (Refer to page 173.)

NOTE
• Under Vector control, the magnetic flux observer is enabled to estimate or measure the flux within the motor using the current
running through the motor and the inverter output voltage. This improves the torque accuracy since the flux of a motor can be
accurately estimated and optimum characteristics can be obtained without being affected by temperature change in the
second resistor.
• Performing pre-excitation (LX signal and X13 signal) under torque control may start the motor running at a low speed even
when the start signal (STF or STR) is not input. This product with the start command ON may also rotate the motor at a low
speed when the speed limit value is set to zero. Confirm that the motor running does not cause any safety problems before
performing pre-excitation.
• The carrier frequency is limited during Vector control. (Refer to page 249.)
• Torque control is not available under the Vector control with PM motors.
• To give the constant torque command in the constant output range, set "1" in Pr.803 Constant output range torque
characteristic selection. (Refer to page 167.)
• For the settings for the SF-V5RU, refer to page 452.
• Vector control is not available for the IP67 model as plug-in options are not available.

 Using the speed command during speed control (Pr.807 = "0") 10

• Speed limit is set by the same method as speed setting during speed control (speed setting by PU (operation panel /
parameter unit), multi-speed setting, plug-in option, etc.)
• When the start signal turns ON, the limit level increases from 0 Hz to the set speed by taking the time set in Pr.7
Acceleration time. When the start signal turns OFF, the limit level at the time decreases to the operation start level of
Pr.10 DC injection brake operation frequency, by taking the time set in Pr.8 Deceleration time.
• When the load has reversed the rotation opposite to the torque polarity, the setting of Pr.809 Reverse-side speed limit
is applied for the speed limit.

 NOTE
• The second acceleration/deceleration time can be set.
• When speed limit command exceeds Pr.1 Maximum frequency setting, the speed limit value becomes Pr.1 setting. When
speed limit command falls below Pr.2 Minimum frequency setting, the speed limit value becomes Pr.2 setting. Also, the
speed limit command is smaller than Pr.13 Starting frequency, the speed limit value becomes 0 Hz.
• To use analog inputs to perform speed limit, calibrate analog input terminals 2 and 4. (Refer to page 400.)
• To use analog inputs to perform speed limit, turn OFF the external signals (RH, RM, RL). If any of the external signals (RH,
RM, RL) is ON, speed limit by multi-speed are enabled.

 Speed limit by parameters (Pr.807 = "1")

• Following the polarity change in the torque command, the polarity of the speed limit value changes. This prevents the
speed from increasing in the torque polarity direction. (When the torque command value is 0, the polarity of the speed limit
value is positive.)
• When Pr.807 Speed limit selection = "0", the setting during speed control is applied for the speed limit. When Pr.807
Speed limit selection = "1", Pr.808 Speed limit is applied for the speed limit.
• When the load has reversed the rotation opposite to the torque polarity, the setting of Pr.809 Reverse-side speed limit
is applied for the speed limit. (The speed limit value and reverse-side speed limit value are limited at Pr.1 Maximum
frequency.)

 Current loop proportional (P) gain adjustment (Pr.824)
• The 100% current loop proportional gain is equivalent to 1000 rad/s during Real sensorless vector control or PM sensorless
vector control, and to 1400 rad/s during Vector control. 7
• For ordinary adjustment, try to set within the range of 50% to 500%.
• Set the proportional gain for during torque control.
• If setting value is large, changes in current command can be followed well and current fluctuation relative to external
8
disturbance is smaller. If the setting value is however too large, it becomes unstable and high frequency torque pulse is
produced.

 Current control integral time adjustment (Pr.825) 9

• Set the integral time of current control during torque control.
• Torque response increases if set small; current however becomes unstable if set too small.
• If the setting value is small, it produces current fluctuation toward disturbance, decreasing time until it returns to original 10
current value.

 Using two types of gain (Pr.834, Pr.835)

• Use Pr.834 Torque control P gain 2 (current loop proportional gain) and Pr.835 Torque control integral time 2
(current loop integral time) if the gain setting needs to be switched according to application or if multiple motors are
switched by a single inverter.
• Pr.834 and Pr.835 is enabled when the second function selection (RT) signal is turned ON.

NOTE
• The RT signal is a second function selection signal which also enables other second functions. (Refer to page 418.)
• To assign the RT signal, set "3" in any parameter from Pr.178 to Pr.189 (Input terminal function selection).

  Adjustment procedure
Adjust if any of phenomena such as unusual vibration, noise, current or overcurrent is produced by the motor or machinery.

1. Change the Pr.824 setting while checking the conditions.

2. If it cannot be adjusted well, change the Pr.825 setting, and perform step 1 again.

Adjustment method
Set Pr.824 lower and Pr.825 longer. First, lower Pr.824 and then check of there is still any abnormal vibration, noise or
current from the motor. If it still requires improvement, make Pr.825 longer.
Lower the setting by 10% each time and set a value that is approximately 80% to 90% of the setting
Pr.824 immediately before the abnormal noise or current improves.
If set too low, current ripple is produced and produces a sound from the motor that synchronizes with it.
Lengthen the current setting by doubling it each time and set a value that is approximately 80% to 90% of
Pr.825 the setting value, immediately before abnormal noise or current is improved.
If set too long, current ripple is produced and produces a sound from the motor that synchronizes with it.

7.1 About position control

This chapter explains the position control under Vector control and PM sensorless vector control.
• A speed command, which is calculated to eliminate the difference between position command and current position, is
output to rotate the motor.
• This inverter can perform simple positioning by point tables or direct commands. (Only the point table method is available
for the standard model.)
• When performing position control, always perform the home position return. Position commands cannot be received until
the completion of the home position return. The home position return is not required when the roll feed mode (Pr.1293 =
"1 or 2") is selected.

*1 Position commands are accepted after the home position return operation is completed. New position data are not accepted during home position
return operation.
*2 A frequency higher than Pr.1 Maximum frequency cannot be set for the speed command. The Pr.2 Minimum frequency setting is disabled.

 Position data settings

• Set the position feed length in Pr.465 to Pr.478.
• The feed length set to each point table is selected by multi-speed terminals (RH, RM, and RL).
• Under Vector control with encoder, set the value calculated with the following formula as the position feed length: (encoder
resolution × rotations per minute × 4).
• For example, to stop the SF-PR-SC motor after 100 times of rotations, the value is calculated as follows:
2048 (pulses/rev) × 100 (rotations per minute) × 4 (multiplier) = 819200 (feed length)
To set 819200 as the first feed length, separate the number into the upper and lower four digits as follows:
Pr.466 (upper digits) = 81 (decimal), Pr.465 (lower digits) = 9200 (decimal)

 Acceleration/deceleration time setting

• Set the acceleration/deceleration time for parameters corresponding to each point table.

186 7. Position Control

7.4 Simple positioning function by point tables
 • The frequency which is the basis of acceleration/deceleration time is Pr.20 Acceleration/deceleration reference
frequency. However, 1 Hz/s is the minimum acceleration/deceleration rate (acceleration/deceleration frequency divided
by acceleration/deceleration time). If the acceleration/deceleration rate is smaller than 1, the motor runs at 1 Hz/s or in the
1
deceleration time.
• The maximum acceleration/deceleration time is limited at 360 seconds.
• During position control, acceleration/deceleration pattern is always the liner acceleration/deceleration. The settings of
2
Pr.29 Acceleration/deceleration pattern selection, Pr.791 Acceleration time in low-speed range, and Pr.792
Deceleration time in low-speed range are ignored.
• This setting is applied to the operation also when the RT signal input or the motor speed is equal to or higher than the
3
Pr.147 Acceleration/deceleration time switching frequency. (The second deceleration time is ignored.)

 Auxiliary function setting 4

• Set the handling and operation methods of the position data in each point table, using Pr.1225, Pr.1229, Pr.1233, Pr.1237,
Pr.1241, Pr.1245, and Pr.1249.
• Set the auxiliary function for parameters corresponding to each point table. 5

• For the command method, select the absolute position command or incremental position command. For the absolute
position command, specify the distance from the home position. For the incremental position command, specify the 9
distance from the current position command.
• For the operation method, select individual or continuous. When continuous operation is selected, next point table is
executed after a command has been executed. 10
• Continuous operation cannot be selected for the point table 7. ("10, 100, or 110" can be set in Pr.1249).
• Individual operation is only executed in the selected point table.
• When the incremental position command is selected and the reverse rotation command is given, the sign of position data

• During continuous operation, the position command speed drops to 0 in each point table operation before starting the next
point table operation.
• During continuous operation, no point table selection signal is received. Select the position feed length using point table before
turning ON the start command.

 Return to home position during point table positioning

• Home position return is performed to match the command coordinates with the machine coordinates. Position control with
an absolute position cannot be performed until the home position is set.
• The returned home position can be set as point 0, and positioning operation is available using this point.

 Home position return procedure

1. Set parameters related to home position return.
• Set the home position return method. (Pr.1282)
• Set the home position return speed. (Pr.1283)
• Set the home position return shifting speed. (Pr.511)
• Set the home position return shift amount if necessary. (Pr.1286 × 10000 + Pr.1285)
• Select whether to use a positive or negative value for the position data for home position return. (Pr.1095)
• Set the position data for home position return. (Pr.1097 × 10000 + Pr.1096)

2. Turn OFF the JOG signal and all point table selection signals.
• Turn OFF all RH, RM, RL and JOG signals. (Not required for EtherCAT communication.)

3. Enable the servo-lock function.

• Turn ON the Pre-excitation/servo ON (LX) signal. (Not required for PROFINET or EtherCAT communication.)
• The servo ON/OFF status is switched to ON state along with state transition (for PROFINET or EtherCAT
communication).

4. Turn ON the start command.

• Turn ON the start signal (STF or STR). (Not required for PROFINET or EtherCAT communication.)
• Turn ON bit 13 of Control word 1 (STW1) (for PROFINET communication only).
• Turn ON bit 4 of Index H6040 (Controlword) (for EtherCAT communication only).

NOTE
• The setting values of Pr.7 and Pr.8 are used as acceleration/deceleration time.

• Unless the home position return is completed (the ZP signal is turned ON), position control cannot be performed (except
when JOG operation during position control or the roll feed mode is enabled).
• The Home position return failure (ZA) signal is output while the home position return warning is activated. To use the ZA
signal, set "56" (positive logic) or "156" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function

  Sudden stop (Pr.464, Pr.1292, and X87 signal)
• When the Sudden stop (X87) signal is assigned to an input terminal, turning ON the X87 signal (normally open input) stops
the operation according to the deceleration time slope set by Pr.464 Digital position control sudden stop deceleration
time. (For EtherCAT communication, the value set in Index H6085 (Quick stop deceleration) can be also used.) When the
deceleration time set in Pr.464 is longer than that set by the current position control command, the deceleration time slope
set by the current position control command is applied. After the operation is stopped, turning OFF the X87 signal (normally
open input) starts position control again. To input the X87 signal, set "87" in any parameter from Pr.178 to Pr.189 (Input
terminal function selection) to assign the function to a terminal.
• When the ones place of the set value in Pr.1292 Position control terminal input selection is "0", the normally open input
is applied and the operation is stopped by turning ON the X87 signal. When the ones place is "1", the normally closed input
is applied and the operation is stopped by turning OFF the X87 signal.

• The normally open input is applied when Pr.1292 = "0, 1, 100, or 101" for the LSP signal or "0, 1, 10, or 11" for the LSN
signal, and turning ON the signal stops the operation. The normally closed input is applied when Pr.1292 = "10, 11, 110,
or 111" for the LSP signal or "100, 101, 110, or 111" for the LSN signal, and turning OFF the signal stops the operation.
• When the Forward stroke end (LSP) signal or Reverse stroke end (LSN) signal is assigned to an input terminal, turning
OFF the LSP/LSN signal (normally closed input) stops the operation according to the deceleration time slope set by Pr.464
Digital position control sudden stop deceleration time. (For EtherCAT communication, the value set in Index H6085
(Quick stop deceleration) can be also used.) When the deceleration time set in Pr.464 is longer than that set by the current
position control command, the deceleration time slope set by the current position control command is applied.
After stopped, the motor cannot be rotated in the counterclockwise (CCW) direction while the LSP signal is OFF, or in the
clockwise (CW) direction while the LSN signal is OFF (normally closed input in both cases).
• The setting of Pr.359 Encoder rotation direction determines the motor rotation direction restricted by the LSP/LSN
signal.
LSP signal: After stopped, the motor cannot be rotated in the CCW (CW) direction when Pr.359 = "101 (100)" while the
signal is OFF (normally closed input).
LSN signal: After stopped, the motor cannot be rotated in the CW (CCW) direction when Pr.359 = "101 (100)" while the
signal is OFF (normally closed input).
• To input the LSP signal, set "88" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.
• To input the LSN signal, set "89" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.
• When the LSP signal or LSN signal is OFF (normally closed input), the Stroke limit warning (LP) signal is turned ON and
"LP" is displayed on the operation panel. To use the Stroke limit warning (LP) signal, set "24" (positive logic) or "124"
(negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function selection) to assign the function.

 Roll feed mode 1 and 2 (Pr.1293) 10

• These modes are used in an application that needs repeated positioning in the same direction, such as a conveyor.
• When the roll feed mode 1 is selected (Pr.1293 = "1"), positioning operation is performed with the current position and
position command set to 0 at start. Position commands are not overflowed and the repeated feed by the increment is
available.
• When the roll feed mode 2 is selected (Pr.1293 = "2"), positioning operation is performed with the position command set
to 0 and the current position set to the value of the previous current position data decremented by the droop pulse at start.
The difference between the position command and the current position at each start is not accumulated.

A workpiece is pressed to a mechanical stopper, and the position where it is stopped is set as the
home position.
Pressing is confirmed when the speed remains equal to or lower than the value set in Pr.865 Low
speed detection for 0.5 second during the torque limit operation. (While the stopper-type home
position is performed, Pr.1289 Home position return stopper torque is applied.) After Pr.1290
Home position return stopper waiting time has passed after pressing is confirmed, the home
position is shifted by the home position shift distance (Pr.1285 and Pr.1286). After a position
command is created and the absolute value of the droop pulse (after electronic gear) reaches the in-
position width set in Pr.426*1 or less, the home position return is completed.
Home position return direction
• Position pulse increasing direction: when Index H6098 = "-65" and the forward rotation command is
given, or when Index H6098 = "-4"
• Position pulse decreasing direction: when Index H6098 = "-65" and the reverse rotation command is
given, or when Index H6098 = "-36"
HP1 (Home position return setting error) will be displayed in any of the following cases:
• Pressing does not last for the time period set in Pr.1290 Home position return stopper waiting

NOTE
• If parameters are copied from an inverter without functions of Pr.1096 and Pr.1097 to a new inverter, "----" is displayed for the
settings of Pr.1096 and Pr.1097 on the operation panel. The operation for the setting of "0 (initial value)" is performed. (Refer
to page 599.)

 Home position return error

• If home position return is not normally completed, the following warnings appear on the operation panel.
Operation panel
Name Possible cause

HP1 Home position return setting error • The home position setting has failed.
• Start signal for the direct command positioning has turned ON without completing
HP2 Home position return uncompleted
the home position return. (Except in the roll feed mode)

• Unless the home position return is completed (the ZP signal is turned ON), position control cannot be performed (except
when JOG operation during position control or the roll feed mode is enabled).
• The Home position return failure (ZA) signal is output while the home position return warning is activated. To use the ZA
signal, set "56" (positive logic) or "156" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function
selection) to assign the function.

 Sudden stop (Pr.464, Pr.1292, and X87 signal)

• When the Sudden stop (X87) signal is assigned to an input terminal, turning ON the X87 signal (normally open input) stops
the operation according to the deceleration time slope set by Pr.464 Digital position control sudden stop deceleration
time. (For EtherCAT communication, the value set in Index H6085 (Quick stop deceleration) can be also used.) When the
deceleration time set in Pr.464 is longer than that set by the current position control command, the deceleration time slope
set by the current position control command is applied. After the operation is stopped, turning OFF the X87 signal (normally
open input) starts position control again. To input the X87 signal, set "87" in any parameter from Pr.178 to Pr.189 (Input
terminal function selection) to assign the function to a terminal.
• When the ones place of the set value in Pr.1292 Position control terminal input selection is "0", the normally open input
is applied and the operation is stopped by turning ON the X87 signal. When the ones place is "1", the normally closed input
is applied and the operation is stopped by turning OFF the X87 signal.

signal, and turning ON the signal stops the operation. The normally closed input is applied when Pr.1292 = "10, 11, 110,
or 111" for the LSP signal or "100, 101, 110, or 111" for the LSN signal, and turning OFF the signal stops the operation. 6
• When the Forward stroke end (LSP) signal or Reverse stroke end (LSN) signal is assigned to an input terminal, turning
OFF the LSP/LSN signal (normally closed input) stops the operation according to the deceleration time slope set by Pr.464
Digital position control sudden stop deceleration time. (For EtherCAT communication, the value set in Index H6085 7
(Quick stop deceleration) can be also used.) When the deceleration time set in Pr.464 is longer than that set by the current
position control command, the deceleration time slope set by the current position control command is applied.
After stopped, the motor cannot be rotated in the counterclockwise (CCW) direction while the LSP signal is OFF, or in the 8
clockwise (CW) direction while the LSN signal is OFF (normally closed input in both cases).
• The setting of Pr.359 Encoder rotation direction determines the motor rotation direction restricted by the LSP/LSN
signal. 9
LSP signal: After stopped, the motor cannot be rotated in the CCW (CW) direction when Pr.359 = "101 (100)" while the
signal is OFF (normally closed input).
LSN signal: After stopped, the motor cannot be rotated in the CW (CCW) direction when Pr.359 = "101 (100)" while the 10
signal is OFF (normally closed input).
• To input the LSP signal, set "88" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.
• To input the LSN signal, set "89" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.
• When the LSP signal or LSN signal is OFF (normally closed input), the Stroke limit warning (LP) signal is turned ON and
"LP" is displayed on the operation panel. To use the Stroke limit warning (LP) signal, set "24" (positive logic) or "124"
(negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function selection) to assign the function.

 Gear ratio calculation (Pr.420, Pr.421)

The position resolution (travel distance per pulse Δ [mm]) is the travel distance per motor rotation Δs [mm] and the feedback
pulse Pf [pulses/rev] of the detector.
Δ : Travel distance per pulse [mm]
Δs
Δ ＝ Δs: Travel distance in one motor rotation [mm]
Pf pf: Number of feedback pulses [pulse/rev] (the number of pulses after the number encoder
pulses is quadruplicated)

The travel distance in 1 command pulse can be separately specified with a parameter and so an integer can be set as the travel
distance in 1 command pulse.
Δs Pr.420
Δ ＝ ×
Pf Pr.421

The following formula shows the relationship between the motor speed and internal command pulse frequency.
Pr.420 No fo: internal command pulse frequency [pulses/s]
fo × = Pf ×
Pr.421 60 No: motor rotation speed [r/min]

NOTE
• The setting of 1/900 or lower is limited at 1/900, and 900 or higher at 900.

Setting example
To set the travel distance per pulse to 0.01 mm in a machine with Δs
= 10 mm while a motor with a 1024 pulse encoder is used.
 : 0.01 [mm]
 s : 10 [mm]
Pf : 4096 [pulse/rev]
Pr.420 4096 pulse/rev 512
= 0.01 mm × =
Pr.421 10 125
Thus, set the parameters as follows: Pr.420 = "512", Pr.421 = "125".

 Relationship between the position resolution and system accuracy

The system accuracy (the positioning accuracy of the machine) is the sum of electric deviation and mechanical deviation.
Normally try to prevent the total deviation from being affected by the electronic deviation. Refer to the following relationship as
a reference.

 Motor stop characteristics
When running the motor by the parameter settings, pulses as much as the motor speed delay to the internal command pulse
1
frequency are accumulated in the deviation counter. These pulses are called droop pulses (ε). The relationship between the
command frequency (fo) and position loop gain (Kp: Pr.422) is shown in the following formula.

Kp 10

The number of droop pulses (ε) is 20480 with the initial value Kp = 10 s-1.
3
Since the inverter has droop pulses during operation, a stop settling time (ts), which is the time between the zero command
output and the motor stop, is required. Set the operation pattern taking into the account the stop setting time.

ts = 3 ×

 In-position width (Pr.426, Y36 signal)

• The Y36 signal is used as the In-position signal.
• If the number of droop pulses (after electronic gear) reaches the Pr.426 setting value or smaller, the In-position (Y36) signal
turns ON. (The number of droop pulses (after electronic gear) is calculated by subtracting the current position (after
electronic gear) from the position command (after electronic gear).)
• To use the Y36 signal, set "36" (positive logic) or "136" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign the function.

 Excessive level error (Pr.427)

• If the number of droop pulses (after electronic gear) reaches the Pr.427 setting value or larger, E.OD (Excessive position
fault) is activated and the inverter output is shutoff. (The number of droop pulses (after electronic gear) is calculated by
subtracting the current position (after electronic gear) from the position command (after electronic gear).) Increase the error
threshold level when a small value is set as the Pr.422 Position control gain setting value. Set a small value for early
detection even when the load is heavy.
• If Pr.427 = "9999", E.OD is not activated regardless of the amount of droop pulses.

 Travel completed signal (MEND signal) 8

• The Travel completed (MEND) signal turns ON when the In-position (Y36) signal is ON and the During position command
operation (PBSY) signal is OFF. To use the MEND signal, set "38" (positive logic) or "138" (negative logic) in any parameter
from Pr.190 to Pr.197 (Output terminal function selection) to assign the function. 9
 Rough match signal (Pr.510, CPO signal)
• The Rough match (CPO) signal turns ON when the remaining command distance (before electronic gear) reaches the
10
Pr.510 setting value or less. (The remaining distance can be calculated by subtracting the position command (before
electronic gear) from the target position (before electronic gear).) To use the Rough match (CPO) signal, set "62" (positive
logic) or "162" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function selection) to assign
the function.

 Position detection signal (Pr.1294 to Pr.1297, FP signal)

• The Position detection level (FP) signal turns ON when the current position (before electronic gear) exceeds the position
detection judgment value (Pr.1295 × 10000 + Pr.1294). To use the FP signal, set "60" (positive logic) or "160" (negative
logic) in any parameter from Pr.190 to Pr.197 (Output terminal function selection) to assign the function.
• Pr.1296 Position detection selection can be set to select whether the position detection is determined on the plus side
or minus side. When "0" is set, the position is detected on both the plus and minus sides. When "1" is set, the position is
detected on the plus side only. When "2" is set, the position is detected on the minus side only.

7.9 Current position retention function
215
 NOTE
• Do not use the current position retention function if the motor shaft is not fixed by the electromagnetic brake or the like while
the inverter output is shut off. Motor shaft rotation causes a position fault.
• Even when the motor shaft is fixed, do not use the function if the motor shaft is rotated by an external force. Motor shaft rotation
causes a position fault.
• Turn the LX signal OFF after the motor stops and servo lock is activated.
• When the FR-E8DS is installed or when the IP67 model is used, the current position retention function is disabled during the
24 V external power supply operation. Even if Pr.538 = "11 or 12", the position data remains cleared while the external 24 V
power is supplied. When the power source is switched to the main circuit power, the position data last stored in EEPROM
before the external power is supplied is used.
• The held position data and the Home position return completed (ZP) signal are cleared in any of the following cases:
The Pr.538 setting is changed.
The setting of electronic gear (settings of Pr.420 and Pr.421) is changed.
The main circuit capacitor life is measured.
Operation is switched between the first and second motors.
The control mode is changed while a value other than "21 or 22" is set in Pr.538.
An inverter protective function has been activated.
Offline auto tuning is performed.
The current position retention function is not available.
The power is turned OFF or the inverter is reset while Pr.538 = "1, 2, 21, or 22".
The motor setting is changed from the EM-A motor (Pr.71 = "1140") to a different motor. Alternatively, the motor setting is
changed from a different motor to the EM-A motor.
While Pr.71 = "1140" (EM-A motor setting), the setting in Pr.80 Motor capacity is changed from 0.75K or lower to 1.5K or
higher. Alternatively, the setting is changed from 1.5K or higher to 0.75K or lower.
• When Pr.538 = "11 or 12", about one second is required to complete writing position data after the LX signal is turned OFF.
Do not turn OFF the power and do not perform the inverter reset during the writing of position data. If the writing is failed due
to power-OFF or inverter reset, the protective function E.OD is activated when the power is turned ON.
• If the inverter output is frequently shut off during the position control operation, do not set "11 or 12" in Pr.538. The frequent
shutoff while Pr.538 = "11 or 12" will shorten the life of the EEPROM.
• When Pr.538 = "11 or 12", position data from -2147483648 to 2147483647 can be stored in EEPROM. When a position data
is out of the range, the data is not stored in EEPROM, and the previous data is cleared.
• To give a command to the inverter via communication, use the current position retention function with Pr.800 = "3". When
Pr.800 = "4" (speed/position switchover) or "5" (position/torque switchover), the held position data and ZP signal may be
cleared since the same control mode as when the MC signal is OFF is performed regardless of the actual signal state until the
inverter power is turned ON and the communication is established.

 Position loop gain (Pr.422, Pr.1298)
• Adjust the gain when a phenomena such as unusual vibration, noise and overcurrent of the motor/machine occurs.
• Increasing the setting value improves traceability for the position command and also improves servo rigidity at a stop, but 9
oppositely may cause an overshoot and vibration.
• The setting range is normally 5 to 50.
Movement/ condition How to adjust Pr.422 10
Increase the setting value.

Response is slow. Increase the setting value by 3 s-1 until immediately before occurrence of an
overshoot, stop-time vibration or other instable phenomenon, and set about
80% to 90% of that value.
Lower the setting value.
Overshoot, stop-time
vibration or other instable Lower the setting value by 3 s-1 until immediately before occurrence of an
phenomenon occurs. overshoot, stop-time vibration or other instable phenomenon, and set about
80% to 90% of that value.

 Position feed forward gain (Pr.423)

• This function is designed to cancel a delay caused by the droop pulses in the deviation counter. Set this parameter when
a sufficient position response cannot be obtained after setting Pr.422.
• When a tracking delay for command pulses poses a problem, increase the setting value gradually within the range where
an overshoot or vibration will not occur.
• This function has no effects on servo rigidity at a stop.
• Normally set this parameter to 0.
• To set Pr.423, set Pr.877 = "1" to enable position feed forward control.

 Model adaptive position control (Pr.446)

• Set each response for position commands and for load and external disturbances individually.
• Set this parameter when a sufficient position response cannot be obtained after setting Pr.422.
• When setting Pr.446, set Pr.877 = "2" to enable the model adaptive position control, and set a value other than "0" in Pr.828
Model speed control gain, and a load inertia ratio in Pr.880 Load inertia ratio.

Adjusting the setting of Pr.698 Speed control D gain suppresses this phenomenon.
• Setting Pr.698 = 100% makes the corner frequency ωf 10 rad/s and reduces the response level to the frequency equal to
or lower than that. (Corner frequency is calculated as follows: ωf = 10 rad/s × Pr.698[%].) Position deviation, however,
increases as a higher value is set to Pr.698.
• This suppression is available also for the servo lock function during speed control (Pr.802 Pre-excitation selection = "1").

 Simple clock function
• When the current year, month, day, hour and minute are set in the parameters above, the inverter internal clock starts 6
ticking. The set date and time can be checked by reading the parameters.

NOTE
• The time data of the internal clock is saved in the inverter's EEPROM every 10 minutes. 7
• The clock does not run while the control circuit power is OFF. The clock needs to be set every time after turning ON the inverter
power.
• When the FR-E8DS is installed and power to the main circuit is turned ON while power is supplied to the inverter from the 24 8
V external power supply, the clock data is reset to the data stored in EEPROM because an inverter reset is to be performed
in the initial setting. To prevent the clock from resetting, set Pr.30 Regenerative function selection. (Refer to page 545.)

• When the FR-LU08 is connected to the inverter, the internal clock of the inverter can be synchronized with the clock in the
FR-LU08 (Real time clock function). The FR-LU08 with battery (CR1216) backup can keep its clock function running even
if the main power of the inverter is turned OFF. (The inverter internal clock stops running when the inverter power is turned
OFF.)
• To adjust the clock in the FR-LU08, set Pr.1006 to Pr.1008 on the FR-LU08.

NOTE
• Time synchronization between the inverter internal clock and the clock in the FR-LU08 is performed every one minute.
• If the FR-LU08 clock is reset due to dead battery for example, the data in the inverter internal clock is used.

 Time synchronization via CC-Link IE TSN communication (Ethernet

 Reset selection (P.E100)

• While P.E100 = "1", or Pr.75 = "1, 3, 15, 17, 10001, 10003, 10015, or 10017", the reset command input is enabled (using
the RES signal or through communication) only when the protective function is activated.

8. (E) Environment Setting Parameters

8.2 Reset selection / disconnected PU detection / PU stop selection
225
 NOTE
• When the RES signal is input during operation, the motor coasts since the inverter being reset shuts off the output. Also, the
cumulative values of electronic thermal O/L relay and regenerative brake duty are cleared.
• When "reset input always enabled" is selected, the reset key on the PU is enabled only when the protective function is
activated.
• During emergency drive operation, reset input is always enabled regardless of the reset selection setting.

 Disconnected PU detection (P.E101) (Standard model only)

• When the inverter detects that the PU connector is disconnected from the inverter for 1 second or more while P.E101 =
"1" or Pr.75 = "2, 3, 16, 17, 10002, 10003, 10016, or 10017", the PU disconnection ("E.PUE") indication is displayed and
the inverter output is shut off.

NOTE
• When the PU has been disconnected before power-ON, the output is not shut off.
• To restart the inverter operation, confirm that the PU is connected before reset.
• When the inverter detects that the PU is disconnected during PU JOG operation while P.E101 or Pr.75 is set to continue the
inverter operation even when the PU is disconnected, the inverter decelerates the motor to stop.
• During RS-485 communication operation via the PU connector, the Reset selection function and the PU stop selection function
are enabled but the Disconnected PU detection function is disabled. (The communication is checked according to Pr.122 PU
communication check time interval.)
• PU disconnection detection function is unavailable for the Ethernet model, the safety communication model, and the IP67
model.

 PU stop selection (P.E102)

• The inverter operation can be stopped in any operation mode (PU, External, or Network) by pressing the STOP/RESET
key on the PU (operation panel / parameter unit).
• When the inverter is stopped by the PU stop function, "PS" is displayed on the operation panel. However, the Fault signal
is not output.
• When P.E102 = "0", or Pr.75 = "0 to 3 or 10000 to 10003", only the inverter in the PU operation mode decelerates to stop
by pressing the STOP/RESET key.

NOTE
• The inverter decelerates to stop (PU stop function) also when the start command is input using a device which has the
command source (set in Pr.551) and then the STOP/RESET key is pressed on a PU which does not have the command
source.
(Example) When the operation panel has the command source and the stop command is input using a USB (FR
Configurator2), the PU stop function is activated.

Stop/restart example for External operation

• The inverter can be restarted by performing the reset operation (by turning OFF and ON the power or inputting the RES 8
signal). When Pr.30 Regenerative function selection = "100 to 102" (no reset when power is supplied to the main circuit),
the inverter can be restarted also when the power is supplied to the main circuit while the FR-E8DS is installed and 24 V
external power is supplied to the inverter (refer to page 545). 9
NOTE
• Even when Pr.250 Stop selection ≠ "9999" is set and coasting stop is selected, using the PU stop function in the External
operation mode does not provide coasting stop but deceleration stop. 10

 Reset limit (P.E107) (Safety communication model / IP67 model)

• When "10" is set in P.E107 or any value from "10000 to 10003, 10014 to 10017" is set in Pr.75, the reset command input
(using the STOP/RESET key or the RES signal) is disabled when the protective function (E.SAF, E.6, E.7, or E.CPU) is
activated. Turn ON the power supply of the inverter again to reset the inverter.

NOTE
• When a communication option is installed, reset is enabled when the protective function (E.SAF, E.6, E.7, or E.CPU) is
activated regardless of P.E107 or Pr.75 setting.
• For the standard model and the Ethernet model, reset limit is fixed to disabled.

CAUTION
• Do not perform a reset while a start signal is being input. Doing so will cause a sudden start of the motor, which
is dangerous.

 Basic operation
• When Pr.295 ≠ "0", the minimum increment when the set frequency is changed with the setting dial can be set.
For example, when Pr.295 = 1.00 Hz, one click (one dial gauge) of the setting dial changes the frequency in increments 6
of 1.00 Hz, such as 1.00 Hz → 2.00 Hz → 3.00 Hz.

NOTE
• When machine speed display is selected in Pr.53 Frequency / rotation speed unit switchover, the minimum increments of
change are determined by Pr.295 as well. Note that the setting value may differ as speed setting changes the set machine
10
speed and converts it to the speed display again.
• For Pr.295, the increments are not displayed.
• The Pr.295 setting is enabled only for the changes to the set frequency. It does not apply to the settings of other parameters
related to frequency.
• When 10 is set, the frequency setting changes in 10 Hz increments. Be cautious of excessive speed (when Automatic
frequency setting enabled).

8.11 Password
 Locking parameters with a password (Pr.296, Pr.297)
• The procedure of locking parameters with a password is as follows.
1
1. Set the parameter reading/writing restriction level to enable the password protection. (Set a value other than "9999"
in Pr.296.) 2
Allowable number of failed password
Pr.296 setting Pr.297 readout
attempts
0 to 6, or 99 Unlimited Always 0
3
100 to 106, 199*1 Limited to 5 times Number of failed password attempts (0 to 5)

*1 If an invalid password is input 5 times while any of "100 to 106, or 199" is set in Pr.296, the password is locked up afterward (the locked parameters
cannot be unlocked even with the valid password). All parameter clear is required to reset the password. (After All parameter clear is performed,
the parameters are returned to their initial values.)
4
2. Write a 4-digit number (1000 to 9998) to Pr.297 as a password (writing is disabled when Pr.296 = "9999"). After a
password is set, parameters are locked and access (reading/writing) to the parameters is limited at the level set in
Pr.296 until the valid password is input to unlock the locked parameters.
5
NOTE
• After a password is set, the Pr.297 readout is always any of "0 to 5". 6
• "LOCD" appears when a password-protected parameter is attempted to be read/written.
• Even if a password is set, the parameters which are written by the inverter, such as parameters related to the life check of
inverter parts, are overwritten as needed.
• Even if a password is registered, reading/writing is enabled for Pr.991 PU contrast adjustment when the parameter unit (FR-
7
PU07) is connected.

 Unlocking the locked parameters (Pr.296, Pr.297)

8
• There are two ways to unlock the locked parameters.
• Enter the password in Pr.297. When a valid password is input, the locked parameters can be unlocked. When an invalid
9
password is input, an error indication appears and the parameters cannot be unlocked. If an invalid password is input 5
times while any of "100 to 106, or 199" is set in Pr.296, the locked parameters cannot be unlocked afterward even with the
valid password (the password is locked up).
• Perform All parameter clear.
10
NOTE
• If the password is forgotten, it can be reset by performing All parameter clear, but the other parameters are also reset.
• All parameter clear cannot be performed during the inverter operation.
• When using FR Configurator2 in the PU operation mode, do not set "0, 4, 5, 99, 100, 104, 105, or 199" (parameter read is
disabled) in Pr.296. Doing so may cause abnormal operation.
• The means to reset the password varies according to how the reset command is sent (from the PU, through RS-485
communication, or via a communication option).

PU (operation panel
RS-485 communication Communication option
or parameter unit)
All parameter clear ○ ○ ○
Parameter clear × × ○

○: Password reset enabled, ×: Password reset disabled

• To perform Parameter clear or All parameter clear with the parameter unit or via a communication option, refer to the
Instruction Manual of each option. (For details of the operation panel, refer to page 20. For details of RS-485 communication,

NOTE
• When "4, 5, 104, or 105" is set in Pr.296 and a password is set, PU JOG frequency is not listed on the parameter unit (FR-

• Changing the PWM carrier frequency can be effective for avoiding the resonance frequency of the mechanical system or
motor, as a countermeasure against EMI generated from the inverter, or for reducing leakage current caused by PWM

NOTE
• The carrier frequency may be automatically lowered in the low-speed range (less than about 10 Hz) for the ND rating, and over
the entire speed range for the LD rating.
Motor noise increases, but not to the point of failure.

 Soft-PWM control (Pr.240)

• Soft-PWM control is a function that changes the motor noise from a metallic sound into an inoffensive, complex tone.
• Setting Pr.240 = "1" will enable the Soft-PWM control.
• To enable the Soft-PWM control, set Pr.72 to 5 kHz or less.

 PWM carrier frequency automatic reduction function (Pr.260)

• Setting Pr.260 = "10" (initial value) will enable the PWM carrier frequency auto-reduction function. If a heavy load is
continuously applied while the inverter carrier frequency is set to 3 kHz or higher (Pr.72 ≥ "3"), the carrier frequency is
automatically reduced to prevent occurrence of the inverter overload trip (electronic thermal O/L relay function) (E.THT).
Motor noise increases, but not to the point of failure.

The carrier frequency will reduce automatically with continuous operation of 85% of the

10 and FR-E846-0095(3.7K) or lower, the carrier frequency will reduce automatically with
2 (ND) operation of 170% of the inverter rated current or higher (only in a low-speed range).
For the FR-E820-0470(11K) or higher and FR-E840-0230(11K) or higher, the carrier
frequency will reduce automatically with operation of 120% of the inverter rated current
or higher.
Without carrier frequency automatic reduction (Perform continuous operation with the
1 (LD) carrier frequency set to 2 kHz or lower or with less than 85% of the inverter rated current
0 for the ND rating.)
2 (ND) Without carrier frequency automatic reduction

NOTE
• Reducing the PWM carrier frequency is effective as a countermeasure against EMI from the inverter or for reducing leakage
current, but doing so increases the motor noise.
• When the PWM carrier frequency is set to 1 kHz or lower (Pr.72 ≤ 1), the increase in the harmonic current causes the fast-
response current limit to activate before the stall prevention operation, which may result in torque shortage. In this case,
disable the fast-response current limit in Pr.156 Stall prevention operation selection.
• The carrier frequency is reduced to as low as 4 kHz under PM sensorless vector control (when driving the MM-GKR or EM-A
motor).

 WARNING
• When measuring the main circuit capacitor capacity (Pr.259 = "1"), the DC voltage is applied to the motor for about 1
second at power OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.

 Life display of the cooling fan

• If a cooling fan speed of less than the specified speed is detected, Fan alarm "FN" is displayed on the operation panel or
the parameter unit. As an alert output, bit 2 of Pr.255 turns ON (set to 1), and the Y90 signal and Alarm (LF) signal are
also output.
• For the terminal used for the LF signal, set "98" (positive logic) or "198" (negative logic) in any parameter from Pr.190 to
Pr.197 (Output terminal function selection).

NOTE
• When the inverter is mounted with two or more cooling fans, "FN" is displayed even only one of the fans is detected.
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

 Display estimated main circuit capacitor residual life (Pr.506)

• Even when the power supply cannot be turned OFF, the remaining life of the main circuit capacitor can be estimated
without stopping the operation. Note that the remaining life of the main circuit capacitor estimated by this function is
theoretical, and should be used as a guideline only.
• The estimated residual life of the main circuit capacitor is displayed in Pr.506.
• The remaining life of the main circuit capacitor is calculated from the energization time and the inverter output power (100%
= Start of service life). When the remaining life of the main circuit capacitor falls below 10%, bit 5 of Pr.255 turns ON and
a warning is output by the Y90 signal.

 Life display of the relay contacts of terminals A, B, and C (Pr.507, Pr.508)

• The degree of deterioration of the relay contacts of terminals A, B, and C is displayed in Pr.507, and that for terminals A2,
B2, and C2 is displayed in Pr.508 (only for the IP67 model).
• The number of times the contacts of relay turn ON is counted down from 100% (0 time) by 1% (500 times). When the
counter reaches 10% (45,000 times), bit 6 or bit 7 (IP67 model only) of Pr.255 turns ON and a warning is output by the
Y90 signal.
• Any value can be set in Pr.507 and Pr.508 (IP67 model only).

 Life display of the inverter module (Pr.509)

• The degree of deterioration of the inverter module is displayed in Pr.509.
• The degree of deterioration of the inverter module is determined by the change in the surrounding air temperature of the
module. (The degree is counted down from 100% (no deterioration).) When the remaining life of the inverter module
reaches 15%, bit 8 of Pr.255 turns ON and a warning is output by the Y90 signal.

 Environmental impact diagnosis function (corrosion level display)

(Pr.198)
• The risk of the inverter's corrosive damage (degree of corrosion) can be checked by using a metal corrosion sensor.
• The degree of corrosion is monitored using the metal corrosion sensor (the degree is counted up from level 1). Use Pr.198
to check the corrosion level. When level 3 is reached, bit 9 of Pr.255 turns ON, a warning is output by the Y90 signal, and
"Cor" appears on the LCD display of the operation panel.

Operation example of the maintenance timer

• The cumulative energization time of the inverter is stored in the EEPROM every hour and displayed in Pr.503 in 100 h
increments. The number indication on Pr.503 stopped at 9998 (999800 hours).
• When the value in Pr.503 reaches the time (100 h increments) set in Pr.504, the Maintenance timer (Y95) signal is output,
and also "MT" is displayed on the operation panel.
• For the Y95 signal output, set "95" (positive logic) or "195" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign the function.

NOTE
• The cumulative energization time is counted every hour. Energization time of less than 1 h is not counted.
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

following formula.

Output current average value

The output time range is 0.5 to 9 seconds. When the output current average value is less than 10% of the setting value in
Pr.557, the output time is 0.5 second, and when it is more than 180%, the output time is 9 seconds.
For example, when Pr.557 = 10 A and the output current average value is 15 A:
15 A / 10 A × 5 s = 7.5 s, thus the Current average monitor signal maintains LOW output for 7.5 seconds.

 Acceleration time setting (Pr.7, Pr.20)
• Use Pr.7 Acceleration time to set the acceleration time required to change the frequency to the frequency set in Pr.20 10
Acceleration/deceleration reference frequency from stop status.
• Set the acceleration time according to the following formula.

Acceleration time setting = Pr.20 × Acceleration time from stop status to maximum frequency / (Maximum frequency - Pr.13)
• For example, the following calculation is performed to find the setting value for Pr.7 when increasing the output frequency
to the maximum frequency of 50 Hz in 10 seconds with Pr.20 = "60 Hz (initial value)" and Pr.13 = "0.5 Hz".

 Deceleration time setting (Pr.8, Pr.20)

• Use Pr.8 Deceleration time to set the deceleration time required to change the frequency to a stop status from the
frequency set in Pr.20 Acceleration/deceleration reference frequency.
• Set the deceleration time according to the following formula.

Deceleration time setting = Pr.20 × deceleration time from maximum frequency to stop / (maximum frequency - Pr.10)

9. (F) Settings for Acceleration/Deceleration

9.1 Setting the acceleration and deceleration time
263
 • For example, the following calculation is used to find the setting value for Pr.8 when decreasing the output frequency from
the maximum frequency of 50 Hz in 10 seconds with Pr.20 = 120 Hz and Pr.10 = 3 Hz.
Pr.8 setting = 120 Hz × 10 s / (50 Hz - 3 Hz) ≈ 25.5 s

NOTE
• If the acceleration/deceleration time is set, the actual motor acceleration/deceleration time cannot be made shorter than the
shortest acceleration/deceleration time determined by the mechanical system J (moment of inertia) and motor torque.
• If the Pr.20 setting is changed, the settings of Pr.125 and Pr.126 (frequency setting signal gain frequency) do not change.
Set Pr.125 and Pr.126 to adjust the gains.
• Under PM sensorless vector control, if the protective function (E.OLT) is activated due to insufficient torque in the low-speed
range, set longer acceleration/deceleration times only in the low-speed range in Pr.791 Acceleration time in low-speed
range and Pr.792 Deceleration time in low-speed range.

 Changing the minimum increment of the acceleration/deceleration time

(Pr.21)
• Use Pr.21 to set the minimum increment of the acceleration/deceleration time.
Setting value "0" (initial value): minimum increment 0.1 s
Setting value "1": minimum increment 0.01 s
• Pr.21 setting allows the minimum increment of the following parameters to be changed.
Pr.7, Pr.8, Pr.16, Pr.44, Pr.45, Pr.791, Pr.792, Pr.1103

NOTE
• Pr.21 setting does not affect the minimum increment setting of Pr.611 Acceleration time at a restart.
• The operation panel provides a 4-digit readout (including the number of decimal places) on a value of parameters. Therefore,
a value of "100" or larger is set/displayed only in increments of 0.1 second even if Pr.21 = "1".
• When Pr.21 is set to "0" after the time is set in 0.01 s increments while Pr.21 is set to "1", the value is displayed in increments
of 0.1 second (rounded down to one decimal place). However, the value for the acceleration/deceleration time setting can be
set in increments of 0.01 second.

 Setting multiple acceleration/deceleration times (RT signal, Pr.44, Pr.45,

Pr.147)
• Pr.44 and Pr.45 are applied when the RT signal is ON or when the output frequency is equal to or higher than the
frequency set in Pr.147 Acceleration/deceleration time switching frequency.
• Even at the frequency lower than the Pr.147 setting, turning ON the RT signal switches the acceleration/deceleration time
to the second acceleration/deceleration time. The priority of the signals and settings is as follows: RT signal > Pr.147
setting.
• When "9999" is set in Pr.45, the deceleration time becomes equal to the acceleration time (time set in Pr.44).
• While the Pr.147 setting is equal to or less than the setting of Pr.10 DC injection brake operation frequency or Pr.13
Starting frequency, the time used as the acceleration/deceleration time switches to the time set in Pr.44 (Pr.45) when the
output frequency reaches or exceeds the Pr.10 or Pr.13 setting.

• The RT signal can be assigned to an input terminal by setting Pr.178 to Pr.189 (Input terminal function selection). Changing
the terminal assignment may affect other functions. Set parameters after confirming the function of each terminal. 5
• The RT signal is the Second function selection signal which also enables other second functions. (Refer to page 418.)

 Setting the acceleration/deceleration time in the low-speed range (Pr.791, 6

Pr.792)
• If torque is required in the low-speed range*1 under PM sensorless vector control, set the Pr.791 Acceleration time in
low-speed range and Pr.792 Deceleration time in low-speed range settings higher than the Pr.7 Acceleration time
7
and Pr.8 Deceleration time settings so that the mild acceleration/deceleration is performed in the low-speed range. (When
the RT signal is turned ON, the second acceleration/deceleration time is prioritized.)

NOTE
• Set Pr.791 (Pr.792) to a value larger than the Pr.7 (Pr.8) setting. If set as Pr.791 < Pr.7, the operation is performed as Pr.791
= Pr.7. If set as Pr.792 < Pr.8, the operation is performed as Pr.792 = Pr.8.
• For the rated current of the MM-GKR and EM-A motors, refer to the Instruction Manual (Connection).

 Faulty acceleration rate detection level (Pr.375)

• Under PM sensorless vector control, if the motor rotation speed exceeds the speed set in Pr.375, E.OA (Acceleration error)
is activated, and the inverter output is shut off.
• The Pr.375 setting value must be much larger than the acceleration/deceleration slope. If the Pr.375 setting value is
smaller than the acceleration/deceleration slope, E.OA (Acceleration error) is activated even during normal operation.

 Emergency stop function (Pr.1103)

• When the Emergency stop (X92) signal is OFF (when the contact is opened), the deceleration stop is performed according
to the settings in the Pr.1103 Deceleration time at emergency stop and Pr.815 Torque limit level 2.
• To input the X92 signal, set "92" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function to a terminal.
• The X92 signal is a normally closed input (NC contact input) when it is input via an external input terminal, and a normally
open input (NO contact input) when it is input via communication.
• "PS" is displayed on the operation panel during activation of the emergency stop function.

• The acceleration/deceleration pattern has the Pr.3 Base frequency (Pr.84 Rated motor frequency under PM motor
control) (fb) as the point of inflection in an S-pattern curve, and the acceleration/deceleration time can be set to be suitable 9
for the motor torque reduction in the constant-power operation range at the base frequency (fb) or more.

• This is useful for preventing collapsing stacks such as on a conveyor. S-pattern acceleration/deceleration B can reduce
the impact during acceleration/deceleration by accelerating/decelerating while maintaining an S-pattern from the present
frequency (f2) to the target frequency (f1).

NOTE
• When the RT signal turns ON during acceleration or deceleration with the S-pattern acceleration/deceleration B enabled, a
pattern of acceleration or deceleration changes to linear at the moment.
• When acceleration/deceleration time (such as Pr.7 and Pr.8) is set to "0 s" under Real sensorless vector control, linear
acceleration and deceleration are performed for the S-pattern acceleration/deceleration (Pr.29 ="1 or 2").
• Set linear acceleration/deceleration (Pr.29 = "0" (initial setting)) when torque control is performed under Real sensorless vector
control. When acceleration/deceleration patterns other than the linear acceleration/deceleration are selected, the protective
function of the inverter may be activated.

• Storage conditions
The remotely-set frequency is stored at the point when the start signal (STF or STR) turns OFF. The remotely-set
frequency is stored every minute after turning OFF (ON) the RH and RM signals together. Every minute, the frequency is
1
overwritten in the EEPROM if the latest frequency is different from the previous one when comparing the two. This cannot
be written using the RL signal.
When the 24 V external power is supplied, the remotely-set frequency is stored at the point when the operation is switched
2
over to the 24 V external power supply operation ("EV" blinks on the operation panel), even while the start signal (STF/
STR) is ON. (The 24 V external power supply operation can be performed when the FR-E8DS is installed or when the IP67
model is used.)

• When switching the start signal from ON to OFF, or changing frequency by the RH or RM signal frequently, set the frequency
setting value storage function (write to EEPROM) invalid (Pr.59 = "2, 3, 12, 13"). If the frequency setting value storage function
is valid (Pr.59 = "1, 11"), the frequency is written to EEPROM frequently, and this will shorten the life of the EEPROM.
• The range of frequency changeable by acceleration (RH) signal and deceleration (RM) signal is 0 to maximum frequency (Pr.1
or Pr.18 setting). Note that the maximum value of set frequency is equal to the total of the main speed and the maximum
frequency.

 Shortest acceleration/deceleration (Pr.292 = "1, 11", Pr.293)

• Set this parameter to accelerate/decelerate the motor at the shortest time. This function is useful when the motor needs
to be accelerated/decelerated at a shorter time, such as for a machine, but the designed value of the machine constant is
not known.
• At acceleration/deceleration, this function adjusts the motor to accelerate/decelerate with the maximum inverter output
torque using the Pr.7 Acceleration time and Pr.8 Deceleration time setting as reference. (Pr.7 and Pr.8 settings are not
changed.)
• Use Pr.293 Acceleration/deceleration separate selection to apply the shortest acceleration/deceleration to one of
acceleration and deceleration only.
When "0" (initial value) is set, the shortest acceleration/deceleration is performed for both acceleration and deceleration.
• Set "11" in Pr.292 when a brake resistor or brake unit is connected. The deceleration time can further be shortened.
• When the shortest acceleration/deceleration is selected under V/F control and Advanced magnetic flux vector control, the
stall prevention operation level during acceleration/deceleration becomes 150% (adjustable using Pr.61 to Pr.63). The
setting of Pr.22 Stall prevention operation level and stall level by analog input are used only during a constant speed
operation.
Under Real sensorless vector control and Vector control, the torque limit level (Pr.22, etc.) is applied during acceleration/
deceleration. The adjustments by Pr.61 to Pr.63 are disabled.
• It is inappropriate to use for the following applications.
- Machines with large inertia (10 times or more), such as a fan. Since stall prevention operation is activated for a long
time, this type of machine may be shut off due to motor overloading, etc.
- When the inverter is always operated at a specified acceleration/deceleration time.

276 9. (F) Settings for Acceleration/Deceleration

9.6 Shortest acceleration/deceleration (automatic acceleration/deceleration)
 NOTE
• Even if automatic acceleration/deceleration has been selected, inputting the JOG signal (JOG operation) or RT signal (Second 1
function selection) during an inverter stop switches to the normal operation and give priority to JOG operation or second
function selection. Note that during operation, an input of JOG and RT signal does not have any influence even when the
automatic acceleration/deceleration is enabled.
• Since acceleration/deceleration is made with the stall prevention operation being activated, the acceleration/deceleration
2
speed always varies according to the load conditions.
• By setting Pr.7 and Pr.8 appropriately, it is possible to accelerate/decelerate with a shorter time than when selecting the
shortest acceleration/deceleration. 3
• The shortest acceleration/deceleration is enabled when the operation starts with the RT signal OFF while this function and the
stop-on-contact control are both enabled. (Stop-on-contact control is not enabled when the RT and RL signals are turned ON
during operation.)
• The shortest acceleration/deceleration is disabled when the operation starts after the RT signal is turned ON during a stop 4
while this function and the stop-on-contact control are both enabled. (Stop-on-contact control is enabled by turning ON the RL
signal.)
• When the automatic acceleration/deceleration function is enabled (Pr.292 ≠ "0"), orientation control is disabled. 5

 Operation mode basics

• The operation mode specifies the source of the start command and the frequency command for the inverter.
• Basic operation modes are as follows.
External operation mode: For giving a start command and a frequency command with an external potentiometer or switches which are
connected to the control circuit terminal.
PU operation mode : For giving a start command and a frequency command with the operation panel or parameter unit.
Network operation mode : For giving a start command and a frequency command via RS-485 communication or Ethernet
(NET operation mode) communication, or using a communication option.

 External operation mode (Pr.79 = "0 (initial value) or 2")

• Select the External operation mode when the start command and the frequency command are applied from a frequency
setting potentiometer, start switch, etc. which are provided externally and connected to the control circuit terminals of the
inverter.
• Generally, parameter change cannot be performed in the External operation mode. (Some parameters can be changed.
Refer to page 237.)

284 10. (D) Operation Command and Frequency Command

10.1 Operation mode selection
 • When Pr.79 = "0 or 2", the inverter starts up in the External operation mode at power-ON. (When using the Network
operation mode, refer to page 290.)
• When parameter changing is seldom necessary, setting "2" fixes the operation mode to the External operation mode.
1
When frequent parameter changing is necessary, setting "0" (initial value) allows the operation mode to be changed easily
to the PU operation mode by pressing the PU/EXT key on the operation panel. After switching to the PU operation mode,
2
always return to the External operation mode.
• The STF or STR signal is used as a start command. The input voltage or current via terminal 2 or 4, multi-speed setting
signal, or JOG signal is used as a frequency command.

 PU operation interlock (Pr.79 = "7")

• The operation mode can be forcibly switched to the External operation mode by turning OFF the PU operation external
interlock (X12) signal. This function will be usable in a case where the inverter does not reply to external command signals
during operation due to the operation mode accidentally unswitched from the PU operation mode to the External operation
mode.
• To input the X12 signal, set "12" in any parameter from Pr.178 to Pr.184 (Input terminal function selection) to assign
the function. (For details on Pr.178 to Pr.184, refer to page 410.)
• Set Pr.79 = "7" (PU operation interlock).
• If the X12 signal is not assigned, the function of the MRS signal is switched to the PU operation interlock signal from MRS
(output stop).

*1 The mode is switched to the External operation mode regardless of the ON/OFF state of the start signal (STF/STR). Thus, the motor runs under
the External operation mode when the X12 (MRS) signal turns OFF while the STF or STR signal is ON. 4
*2 When a fault occurs, the inverter can be reset by pressing the STOP/RESET key on the operation panel.

NOTE
• The operation mode cannot be switched to the PU operation mode with the start signal (STF/STR) ON state even if the X12 5
(MRS) signal turns ON.
• If the MRS signal is ON and Pr.79 is written to a value other than "7" when the MRS signal is used as the PU interlock signal,
the MRS signal will act as a regular MRS function (output stop). Also, when Pr.79 = "7", the MRS signal becomes the PU
interlock signal. 6
• The logic of the signal follows the Pr.17 MRS/X10 terminal input selection setting also when the MRS signal is used as the
PU operation interlock signal. When Pr.17 = "2 to 5", ON and OFF in the table above are reversed.
• Changing the terminal assignment using Pr.178 to Pr.184 (Input terminal function selection) may affect the other functions. 7
Set parameters after confirming the function of each terminal.

 Switching operation mode by external signal (X16 signal) 8

• When External operation and the operation from the operation panel are used together, the PU operation mode and
External operation mode can be switched during a stop (during motor stop, start command OFF) by using the PU/External
operation switchover (X16) signal. 9
• When Pr.79 = "0, 6, or 7", switching between the PU operation mode and External operation mode is possible. (When
Pr.79 ="6", switchover is enabled during operation.)
• To input the X16 signal, set "16" in any parameter from Pr.178 to Pr.184 (Input terminal function selection) to assign 10
the function to a terminal.

 Selection of command source in the network (NET) operation mode
(Pr.550)
• Any of the PU connector, the Ethernet connector, or the communication option can be specified for the command source
in the NET operation mode.
• For example, whether or not the communication option is installed, set Pr.550 = "2" to write parameters or give the start
and frequency commands using the PU connector through communication in the NET operation mode.

NOTE
• In the initial setting, "9999" (communication option automatic recognition) is set for Pr.550. Thus, if the communication option
is installed, parameters cannot be written or the start and frequency commands cannot be sent by communications through
the PU connector or the Ethernet connector. (Monitoring or parameter reading can be performed.)

 Selection of the command source of the PU operation mode (Pr.551)

• Any of the PU connector, operation panel, or USB connector can be specified for the command source in the PU operation
mode.
• Set Pr.551 to write parameters or execute the start and frequency commands through communication in the PU operation
mode: Pr.551 = "2" when using the PU connector, and Pr.551 = "3" or "9999" when using the USB connector.

NOTE
• The PU operation mode has a higher priority when Pr.550 = "2" (NET mode using the PU connector) and Pr.551 = "2" (PU
mode using the PU connector). For this reason, if the communication option is not mounted, switching to the Network operation
mode is no longer possible.
• The changed value is applied after the next power-ON or inverter reset.

 *3 In the PU JOG operation mode, operation always stops when the PU is disconnected. The operation at a PU disconnection fault (E.PUE)
occurrence is as set in Pr.75 Reset selection/disconnected PU detection/PU stop selection.
*4 The operation depends on the communication option setting. 1
 Selecting the command interface in the Network operation mode (Pr.338,
Pr.339)
• Selecting a command interface is required for the following two types of commands: the operation command using the start
2
signals and the signals related to the inverter function selection, and the speed command using signals related to the
frequency setting.
• The following table shows the command interface for each function in the Network operation mode, determined by the
3
parameter settings: an external terminal or a communication interface (PU connector, Ethernet connector, or
communication option).

NOTE
• The communication interface selection is determined by the settings of Pr.550 and Pr.551.
• The settings of Pr.338 and Pr.339 can be changed during operation when Pr.77 = "2". Note that the changed setting is applied
after the inverter has stopped. Until the inverter has stopped, the previous setting of the interface for the operation command
and the speed command in the Network operation mode is valid.

 Changing the command interface using a signal input via external

terminal (X67 signal)
• In the Network operation mode, the command interface for the operation command and the speed command can be
changed using the Command source switchover (X67) signal. This method may be useful to use both external terminal
and communication interface by using a different interface according to the command type.
• For the X67 signal, set "67" to any parameter from Pr.178 to Pr.184 (Input terminal function selection) to assign the
function to a control circuit terminal.

298 10. (D) Operation Command and Frequency Command

10.3 Start command source and frequency command source during communication operation
 • When the X67 signal is OFF, the command interface for the operation command and the speed command is the control
circuit terminal.

NOTE
• The ON/OFF state of the X67 signal is applied only during a stop. When the terminals are switched during operation, the ON/ 3
OFF state is reflected after a stop.
• When the X67 is OFF, a reset via communication is disabled.
• Changing the terminal assignment using Pr.178 to Pr.184 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

The acceleration/deceleration times cannot be set separately.
These parameters can be selected from among simple mode parameters when the LCD operation panel (FR-LU08) or the
5
parameter unit (FR-PU07) is connected to the inverter.
*1 60 Hz is initially set in Pr.20 in Group 1, and 50 Hz in Group 2. (Refer to page 54).

 JOG operation by inputting signals (JOG signal and JOG2 signal)
• Operation can be started and stopped by the start signals (STF and STR signals) when the Jog operation selection (JOG)
signal or Jog operation selection 2 (JOG2) signal is ON. (For the operation method, refer to page 48.)
7
• The JOG signal can be input only via a control circuit terminal. For the JOG signal, set "5" to any parameter from Pr.178
to Pr.184 (Input terminal function selection) to assign the function to a control circuit terminal.
• The JOG2 signal can be input via a control circuit terminal or via communication. For the JOG2 signal, set "30" to any
8
parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the function to a control circuit terminal.
• Use the JOG acceleration/deceleration time function (Pr.16) to set the acceleration/deceleration time for JOG operation.

 NOTE
• The priority of the frequency command given by the external signals is as follows: JOG operation (JOG/JOG2 signal) > stop-

analog input (AU signal) > pulse train input (option FR-E8AXY) > 16-bit digital input (option FR-A8AX) > terminal 2 analog
input. Note that stop-on-contact control is disabled when PID control is enabled.
• The reference frequency during acceleration/deceleration depends on the Pr.29 Acceleration/deceleration pattern
selection setting. (Refer to page 267.)
• The Pr.15 setting should be equal to or higher than the Pr.13 Starting frequency setting.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
• During JOG operation, the second acceleration/deceleration function using the RT signal is disabled. (Other second functions
are enabled (refer to page 418).)
• When Pr.79 Operation mode selection = "4", JOG operation is started by one push of the RUN key on the operation panel
or the FWD/REV key on the parameter unit, and stopped by the STOP/RESET key.
• This function is invalid when Pr.79 = "3".

NOTE
• In the initial setting, if two or more speed switches (signals) are simultaneously turned ON, priority is given to the switch (signal)
for the lower speed. For example, when both RH and RM signals turn ON, the RM signal (Pr.5) has the higher priority.
• The RH, RM and RL signals are assigned to the terminals RH, RM and RL, respectively, in the initial status. To assign each
signal to a different terminal, set "0" (RL signal), "1" (RM signal), or "2" (RH signal) in any parameter from Pr.178 to Pr.189
(Input terminal function selection).

Set the frequencies in Pr.24 to Pr.27, Pr.232 to Pr.239. (In the initial status, 4th to 15th speeds are invalid.)
• To input the REX signal, set "8" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function.

*1 When the RH, RM and RL signals are OFF and the REX signal is ON while "9999" is set to Pr.232 Multi-speed setting (speed 8), the inverter
operates at the frequency set in Pr.6.

NOTE
• The priority of the frequency command given by the external signals is as follows: JOG operation (JOG/JOG2 signal) > stop-
on-contact control (RL/RT signal) > multi-speed operation (RL/RM/RH/REX signal) > PID control (X14 signal) > terminal 4
analog input (AU signal) > pulse train input (option FR-E8AXY) > 16-bit digital input (option FR-A8AX) > terminal 2 analog
input. Note that stop-on-contact control is disabled when PID control is enabled. (For details on frequency commands given
by analog input, refer to page 400.)
• The input compensation of multi-speed setting is enabled when the inverter is in the External operation mode or PU/External
combined operation mode (Pr.79 = "3 or 4").
• Multi-speed parameters can also be set during PU operation or External operation.
• The Pr.24 to Pr.27 and Pr.232 to Pr.239 settings have no priority among them.
• When Pr.59 Remote function selection ≠ "0", the multi-speed setting is invalid since the RH, RM, and RL signals are for
remote setting.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

 Electronic thermal O/L relay operation characteristic for induction motor

(Pr.9)
• This function detects the overload (overheat) of the motor and shut off the inverter output by stopping the operation of the
transistor at the inverter output side.
• Set the rated current (A) of the motor in Pr.9 Electronic thermal O/L relay. (If the motor has both 50 Hz and 60 Hz ratings
and the Pr.3 Base frequency is set to 60 Hz, set to 1.1 times the 60 Hz rated motor current.)
• Set "0" in Pr.9 to avoid activating the electronic thermal relay function; for example, when using an external thermal relay
for the motor.
(Note that the output transistor protection of the inverter is activated. (E.THT))

*3 When the electronic thermal relay function dedicated to the Mitsubishi Electric constant-torque motor is set, this characteristic curve applies to
operation. (For selection of the operation characteristic, refer to page 424.)
*4 Transistor protection is activated depending on the temperature of the heat sink. The protection may be activated even with less than 150%
depending on the operating conditions.

NOTE
• The internal accumulated heat value of the electronic thermal relay function is reset to the initial value by the inverter's power
reset or reset signal input. Avoid unnecessary reset and power-OFF.
• Install an external thermal relay (OCR) between the inverter and motors to operate several motors, a multi-pole motor or a
dedicated motor with one inverter. When setting an external thermal relay, note that the current indicated on the motor rating
plate is affected by the line-to-line leakage current. The cooling effect of the motor drops during low-speed operation. Use a
motor with built-in thermal protector. (For details of the line-to-line leakage current, refer to the Instruction Manual
(Connection).)
• When the difference between the inverter and motor capacities is large and the set value is small, the protective characteristics
of the electronic thermal relay function will be deteriorated. Use an external thermal relay in such cases.
• A dedicated motor cannot be protected by an electronic thermal O/L relay. Use an external thermal relay.
• The transistor protection thermal O/L relay is activated early when the Pr.72 PWM frequency selection setting is increased.

 Electronic thermal O/L relay when using PM motor (Pr.9)

• This function detects the overload (overheat) of the motor and shut off the inverter output by stopping the operation of the
transistor at the inverter output side.
• Set the rated current (A) of the motor in Pr.9 Electronic thermal O/L relay.
• Set "0" in Pr.9 to avoid activating the electronic thermal relay function; for example, when using an external thermal relay
for the motor.
(Note that the output transistor protection of the inverter is activated. (E.THT))
• When the MM-GKR or EM-A motor is used, the rated motor current is automatically set by PM parameter initialization.

*1 Depending on the settings of Pr.607 and Pr.608, this thermal protection may not be provided as set, as an inverter overload trip (electronic thermal
relay function) (E.THT) may be activated before the thermal protection.

 Electronic thermal O/L relay pre-alarm (TH) and warning signal (THP
signal)
• If the accumulated electronic thermal value reaches 85% of the Pr.9 or Pr.51 setting, electronic thermal O/L relay function
pre-alarm (TH) is displayed and the electronic thermal O/L relay pre-alarm (THP) signal is output. If the value reaches
100% of the Pr.9 setting, the motor thermal protection (E.THM/E.THT) is activated to shut off the inverter output. The
inverter output is not shut off with the TH display.

Set parameters after confirming the function of each terminal.

 PTC thermistor input (Pr.561, Pr.1016, E.PTC)

This function is used to protect the motor from overheating by inputting outputs from the motor's built-in PTC thermistor to the
inverter. It is recommended that a PTC thermistor whose resistance increases most rapidly around the rated activating
temperature (TN±DT) is used.

 • Outputs from the motor's built-in PTC thermistor can be input to terminals 2 and 10. If the input from the PTC thermistor
reaches the resistor value set in Pr.561 PTC thermistor protection level, E.PTC (PTC thermistor operation) shuts off the
inverter output.
• Confirm the characteristic of the PTC thermistor to be used, and set the resistance for Pr.561 around the center of the R1
and R2 values shown on the figure above so that it does not deviate from the protective function activating temperature
TN. If the Pr.561 setting becomes too close to R1 or R2, the protective function activating temperature may be too hot
(protection is delayed), or too cold (too much protection).
• When the PTC thermistor protection is enabled (Pr.561 ≠ "9999"), the resistance value for the PTC thermistor can be
displayed on the operation panel or via RS-485 communication. (Refer to page 348.)
• When the PTC thermistor protection level setting is used, use Pr.1016 PTC thermistor protection detection time to set
the time from when the resistance of the PTC thermistor reaches the protection level until the protective function (E.PTC)
is activated.
• If the resistance of the PTC thermistor falls below the protection level within the protection detection time, the elapsed time
count is cleared.

NOTE
• When using terminal 2 for PTC thermistor input (Pr.561 ≠ "9999"), terminal 2 does not operate as an analog frequency
command terminal. When a function for the PID control or dancer control is assigned to terminal 2, the function is disabled.
Use Pr.133 PID action set point to set the set point for the PID control. When the PID control and dancer control are disabled
(Pr.128 PID action selection = "0") and Pr.858 = "0", terminal 4 operates as follows.
Pr.79 = "4" or External operation mode is selected: Terminal 4 input is valid regardless of ON/OFF state of the AU signal.
Pr.79 = "3": Frequency command given via terminal 4 is valid only when the AU signal is ON.
• To input power to the PTC thermistor power supply, always use the terminal 10 and do not use any other terminals or an
external power supply. Otherwise, E.PTC (PTC thermistor protection) does not operate properly.
• When E.PTC is activated, the alarm display, "External protection (AU terminal)", may appear on the parameter unit (FR-PU07),
but it is not a fault.

 Overheat protection to match the characteristic of the motor (Pr.600 to

Pr.604, Pr.692 to Pr.696)
• The activation level of the electronic thermal O/L relay can be varied to match the motor temperature characteristic.
• The electronic thermal O/L relay operation level can be set with the combination of three points (Pr.600, Pr.601), (Pr.602,
Pr.603), (Pr.604, Pr.9). Two or more points are required for setting.

 11.2 Cooling fan operation selection
A cooling fan is built into the inverter can be controlled.

Pr. Name Initial value Setting range Description

Cooling fan ON/OFF control disabled. (The cooling fan is always ON at
0 power ON.)
A cooling fan operates at power ON.
244 Cooling fan
1 Cooling fan ON/OFF control enabled.
H100 operation selection
The fan is always ON while the inverter is running. During a stop, the
1
inverter status is monitored and the fan switches ON/OFF according to
the temperature.

 Cooling fan always ON (Pr.244 = "0")

• When Pr.244 = "0", the cooling fan operates at power ON. If the fan stops at this time, the inverter finds that the fan
operation is faulty and the indication of the "FN" (Fan alarm) is displayed on the operation panel. The Fan fault output (FAN)
signal and the Alarm (LF) signal are output.
• For the FAN signal output, set "25" (positive logic) or "125" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection). For the LF signal, set "98" (positive logic) or "198" (negative logic).

 Cooling fan operation control (Pr.244 = "1" (initial value))

• The cooling fan operation is controlled when Pr.244 = "1". When the inverter is running, the cooling fan operates constantly.
When the inverter is stopped, the cooling fan operates depending on the temperature of the inverter heat sink. If the fan
stops although it meets the conditions for running, fan operation is regarded as faulty, "FN" is displayed on the operation
panel, and the FAN signal and LF signals are output.

 Cooling fan operation command (Y206) signal

• The Cooling fan operation command (Y206) signal can be output when the inverter cooling fan meets the conditions for
running. The function can be used when the fan installed on the enclosure is synchronized with the inverter cooling fan.
• The Y206 signal indicates the operating command condition of the inverter cooling fan depending on the power supply ON/
OFF or the Pr.244 settings. The signal does not indicate the actual operation of the cooling fan. (The signal is output even
if the cooling fan is stopped due to a fault.)
• To use the Y206 signal, set "206" (positive logic) or "306" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign function to an output terminal.

NOTE
• The cooling fan is installed on the FR-E820-0080(1.5K) or higher, FR-E840-0040(1.5K) or higher, FR-E860-0027(1.5K) or
higher, FR-E820S-0080(1.5K) or higher, and FR-E846-0026(0.75K) or higher.
• If the safety stop function is activated to shut off the inverter output in the FR-E820-0080(1.5K), FR-E820-0110(2.2K), FR-
E820S-0080(1.5K), or FR-E820S-0110(2.2K), the cooling fan operates at the next power-ON.
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

11.5 Initiating a protective function 11

A fault (protective function) is initiated by setting the parameter.

This function can be used to check how the system operates at activation of a protective function. 12
Pr. Name Initial value Setting range Description

16 to 253
The setting range is the same with the one for fault data codes of the
inverter (which can be read through communication). Written data is not
13
997 stored in EEPROM.
Fault initiation 9999
H103
The read value is always "9999". The protective function is not
9999
activated with this setting. 14
• To initiate a fault (protective function), set the assigned number of the protective function to be initiated in Pr.997.
• The value set in Pr.997 is not stored in EEPROM.
• When the protective function is activated, the inverter output is shut off and the inverter displays the fault indication and 15
outputs a Fault (ALM) signal.
• The latest fault in the fault history is displayed while the fault initiation function is in operation. After a reset, the fault history
goes back to the previous status. (The protective function generated by the fault is not saved in the fault history.) 16
• Perform inverter reset to cancel the protective function.
• For the selectable parameter by Pr.997 and the corresponding protective functions, refer to the Instruction Manual
(Maintenance). 17
NOTE
• If a protective function is already operating, no fault can be activated by Pr.997.
• The retry function is disabled when a protective function has been initiated by the fault initiation function. 18
• If a fault occurs after a protective function has been activated, the protective function indication does not change. The fault is
not saved in the fault history either.
• When the FR-E8TR or the FR-E8TE7 is installed, Pr.997 cannot be set to "201" (safety circuit fault).

 11.6 I/O phase loss protection selection
The output phase loss protection function, which stops the inverter output if one of the three phases (U, V, W) on the inverter's
output side (load side) is lost, can be disabled.
The input phase loss protective function on the inverter input side (R/L1, S/L2, T/L3) can be disabled.

Pr. Name Initial value Setting range Description

251 Output phase loss 0 Output phase loss protection disabled
1
H200 protection selection 1 Output phase loss protection enabled
872 Input phase loss 0 Input phase loss protection disabled
1
H201*1 protection selection 1 Input phase loss protection enabled
*1 Available for the three-phase power input model only.

 Output phase loss protection selection (Pr.251)

• When Pr.251 is set to "0", output phase loss protection (E.LF) becomes invalid.

 Input phase loss protection selection (Pr.872)

• When Pr.872 = "1", Input phase loss (E.ILF) protection is activated if one of three phases is continuously lost for 1 second.

NOTE
• When several motors are connected, output phase loss cannot be detected even if the wiring to one motor loses phase.
• In the case of R/L1, S/L2 phase loss, the input phase loss protection does not operate, and the inverter output is shut off.
• If an input phase loss continues for a long time, the lives of converter section and capacitor of the inverter become shorter.
• If the load is light or during a stop, lost phase cannot be detected because detection is performed based on the fluctuation of
bus voltage. Large unbalanced phase-to-phase voltage of the three-phase power supply may also cause input phase loss
protection (E.ILF).
• Phase loss cannot be detected during regeneration load operation.

This function allows the inverter to reset itself and restart at activation of the protective function (fault indication). The retry
generating protective functions can also be selected. 12
When the automatic restart after instantaneous power failure function is selected (Pr.57 Restart coasting time ≠ "9999"), the
restart operation is also performed after a retry operation as well as after an instantaneous power failure. (For restart operation,
refer to page 502 and page 508 for selection.) 13

 Setting the retry function (Pr.67, Pr.68)
• When the inverter protective function is operating (fault indication), the retry function automatically cancels (resets) the
protective function after the time set in Pr.68. The retry function then restarts the operation from the starting frequency.
18
• The retry function is enabled when the Pr.67 setting is other than "0". Set the number of retries at activation of the protective
function in Pr.67.

1 to 10 Not available 1 to 10 times
101 to 110 Available 1 to 10 times 20
• When retries fail consecutively the number of times set in Pr.67, a retry count excess (E.RET) occurs, resulting in an
inverter retries. (Refer to the Retry failure example.)
• Use Pr.68 to set the waiting time from a protective function activation to a retry in the range of 0.1 to 600 s.
• During retry operation, the During retry (Y64) signal is ON. For the Y64 signal, set "64" (positive logic) or "164" (negative
logic) in any parameter from Pr.190 to Pr.197 (Output terminal function selection) to assign the function.

 Retry count check (Pr.69)

• Reading the Pr.69 value provides the cumulative number of successful restart times made by retries. The cumulative count
in Pr.69 increases by 1 when a retry is successful. Retry is regarded as successful when normal operation continues
without a fault for the Pr.68 setting multiplied by four or longer (3.1 seconds at the shortest). (When retry is successful, the
cumulative number of retry failures is cleared.)

NOTE
• Use the retry function only when the operation can be resumed after resetting a protective function activation. Making a retry
against the protective function, which is activated by an unknown condition, will lead the inverter and motor to be faulty. Identify
and remove the cause of the protective function activation before restarting the operation.
• If the retry function operates during PU operations, the operating conditions (forward/reverse rotation) are stored; and
operations resume after retry reset.
• Only the fault details for the first fault that occurred during retry are stored in the fault history.
• The reset by the retry function does not clear the accumulated data of the electronic thermal O/L relay, regenerative brake
duty, etc. (This is different from power supply reset or reset by RES signal.)
• When the parameter storage device fault (control circuit board) (E.PE) is occurring and reading of the retry-function-related
parameters is not possible, retry cannot be operated.
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

The inverter can continue driving the motor in case of emergency such as a fire, since protective functions are not activated
even if the inverter detects a fault. Using this function may damage the motor or inverter because driving the motor is given the
highest priority. Use this function for emergency operation only. The operation can be switched to the commercial power supply
operation at the occurrence of a fault which may cause damage of the inverter.

  Retry operation during emergency drive operation (Pr.515, Pr.514)
• Set the retry operation during emergency drive operation. Use Pr.515 Emergency drive dedicated retry count to set the
retry count, and use Pr.514 Emergency drive dedicated retry waiting time to set the retry waiting time.
• The ALM signal output conditions depend on the Pr.67 Number of retries at fault occurrence setting. The signal is not
output when Pr.67 = "0". (Refer to page 319.)
• For the protective functions (faults) for which retry is permitted during emergency drive operation, refer to page 327.

NOTE
• The Pr.65 Retry selection is disabled during emergency drive operation.

 Electronic bypass during emergency drive (Pr.136, Pr.139)

• For selecting the commercial mode (Pr.523 = "3[][], 4[][]"), setting is required as follows.
Set Pr.136 MC switchover interlock time and Pr.139 Automatic switchover frequency from inverter to bypass
operation and assign the MC2 and MC3 signals to output terminals.
Select V/F control, Advanced magnetic flux vector control, or Real sensorless vector control. (Under PM sensorless vector
control, the operation is not switched over to the commercial power supply operation and the output is shut off.)
• During emergency drive operation, the operation is switched over to the commercial power supply operation when any of
the following conditions is satisfied.
A fault for which retry is not permitted occurs while Pr.523 = "3[][]".
A fault occurs while Pr.523 = "4[][]".
• While the motor is driven by the inverter during emergency drive operation, if a condition for electronic bypass is satisfied,
the output frequency is accelerated/decelerated to the Pr.139 setting. When the frequency reaches the set frequency, the
operation is switched over to the commercial power supply operation. (The operation is immediately switched over to the
commercial power supply operation during output shutoff due to a fault occurrence.)
• If the parameter for electronic bypass is not set while the commercial mode is set (Pr.523 = "3[][], 4[][]"), the operation is
not switched over to the commercial power supply operation even when a condition for switchover is satisfied, and the
output is shut off.
• To assign the MC2 and MC3 signals to output terminals, use any two parameters from Pr.190 to Pr.192, and Pr.197
(Output terminal function selection) and set "18" (positive logic) for the MC2 signal and set "19" (positive logic) for the
MC3 signal.

 11.9 Checking faulty area in the internal storage device
When E.PE6 (Internal storage device fault) occurs, faulty area in the internal storage device can be checked by reading Pr.890.
When the read value of Pr.890 is "7" or smaller, an inverter reset after All parameter clear can return the operation to normal.
(The parameters that had been changed before All parameter clear must be set again.)

• If the set frequency is less than the Pr.2 setting, the output frequency is clamped at the Pr.2 setting (does not fall below
the Pr.2 setting).

NOTE
• To operate with a frequency higher than 60 Hz using frequency-setting analog signals, change the Pr.125 (Pr.126) (frequency
setting gain) setting. Simply changing the Pr.1 and Pr.18 settings does not enable the operation at a frequency higher than
60 Hz.
• Under Real sensorless vector control and PM sensorless vector control, the upper and lower limits are for the commanded
frequency. The final output frequency that is decided by each control may exceed the lower or upper limits.
• When Pr.15 Jog frequency is less than the Pr.2 setting, the Pr.15 setting takes precedence.
• If a jump frequency that exceeds the setting of Pr.1 (Pr.18) is set, the maximum frequency setting is the set frequency. If the
jump frequency is less than the setting of Pr.2, the jump frequency is the set frequency. (The set frequency can be less than
the minimum frequency.) When stall prevention is activated to decrease the output frequency, the output frequency may drop
below the setting of Pr.2.

CAUTION
• Note that when Pr.2 is set to any value equal to or higher than Pr.13 Starting frequency, simply turning ON the start
signal runs the motor at the frequency set in Pr.2 even if the command frequency is not given.

 11.12 Stall prevention operation
V/F Magnetic flux

This function monitors the output current and automatically changes the output frequency to prevent the inverter from shutting
off due to overcurrent, overvoltage, etc. It can also limit the stall prevention and fast-response current limit operation during
acceleration/deceleration and power/regenerative driving.
This function is disabled under Real sensorless vector control, Vector control, and PM sensorless vector control.
• Stall prevention:
If the output current exceeds the stall prevention operation level, the output frequency of the inverter is automatically
changed to reduce the output current. Also, the second stall prevention function can limit the output frequency range in
which the stall prevention function is enabled.
• Fast-response current limit:
If the current exceeds the limit value, the output of the inverter is shut off to prevent an overcurrent.

*3 Setting values "100, 101" can be individually set for power driving and regenerative driving. The setting value "101" disables the fast-response
current limit during power driving.

NOTE
• When the load is heavy or the acceleration/deceleration time is short, stall prevention operates and acceleration/deceleration
may not be performed according to the time set. Set Pr.156 and stall prevention operation level to the optimum values.
• For lift applications, make settings to disable the fast-response current limit. Otherwise, the torque may be insufficient, causing
the load to drop.

11.12 Stall prevention operation
 Adjusting the stall prevention operation signal and output timing (OL
signal, Pr.157) 11
• If the output current exceeds the stall prevention operation level and stall prevention is activated, or the fast-response
current limit is enabled, Overload warning (OL) signal turns ON for 100 ms or more. The output signal turns OFF when the
output current falls to the stall prevention operation level or less. 12
• Pr.157 OL signal output timer can be used to set whether to output the OL signal immediately, or whether to output it
after a certain time period has elapsed.
• This function also operates during regeneration avoidance operation ("OLV" (overvoltage stall)). 13
• For the OL signal, set "3" (positive logic) or "103" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal
function selection) to assign the function to an output terminal.

NOTE 17
• If the stall prevention operation has lowered the output frequency to 1 Hz and kept the level for 3 seconds, the stall prevention

• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

• When operating at high speeds above the rated motor frequency, acceleration may not be made as the motor current does
not increase. Also, when operating in the high-frequency range, the current flowing to the locked motor becomes less than
the rated output current of the inverter. Even if the motor is stopped, the protective function does not operate (OL). In a
case like this, the stall prevention level can be reduced in the high-frequency range to improve the motor's operating
characteristics. This is useful when operating up to the high speed range, such as when using a centrifuge. Normally, set
Pr.66 Stall prevention operation reduction starting frequency to 60 Hz, and Pr.23 Stall prevention operation level
compensation factor at double speed to 100%.
• Calculation formula for stall prevention operation level

Output frequency (Hz) 400 Hz

• When Pr.23 = "9999" (initial value), the stall prevention operation level is constant at the Pr.22 level up to 590 Hz.

11. (H) Protective Function Parameters

11.12 Stall prevention operation
337
  Protecting equipment and limiting the load by the torque limit (Pr.277)
• Set Pr.277 Stall prevention operation current switchover = "1" to enable the torque limit.
• If the output torque (current equivalent to the torque) exceeds the stall prevention operation level, the output torque is
limited by adjusting the output frequency. The stall prevention operation level in such a case is based on the rating torque
of the motor.

NOTE
• The torque limit cannot work properly when two or more motors are driven by one inverter.
• In the constant power range (Pr.3 Base frequency), the torque limit is activated at the torque less than the stall prevention
operation level, since the magnetic flux decreases.
• When the torque limit is activated during regenerative driving, the output frequency is increased up to the maximum frequency.
• The toque limit is not activated at the frequency of 5 Hz or less during deceleration.
• When using the torque limit under V/F control, note the following points:
- Use the inverter whose capacity is the same as that of the motor.
- The stall prevention operation level (torque limit level) is based on the rating torque of the motor whose capacity is the same
as that of the inverter.
- When a large value is set in Pr.0 Torque boost, the torque limit may be activated in the low-speed range.
- If more accurate torque limit is required, select Advanced magnetic flux vector control.

 Setting two stall prevention operation levels (Pr.48)

• Turning ON the RT signal enables Pr.48 Second stall prevention operation level.
• To input the RT signal, set "3" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function.

NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
• The RT signal is the Second function selection signal which also enables other second functions. (Refer to page 418).

 Further prevention of a trip (Pr.154)

• Set Pr.154 = "11" when the overvoltage protective function (E.OV[]) is activated during stall prevention operation in an
application with large load inertia. Note that turning OFF the start signal (STF/STR) or varying the frequency command
during stall prevention operation may delay the acceleration/deceleration start.

CAUTION
• Do not set the stall prevention operation current too low.
Doing so will reduce the generated torque.
• Be sure to perform the test operation.
Stall prevention operation during acceleration may extend the acceleration time.
Stall prevention operation during constant-speed operation may cause sudden speed changes.
Stall prevention operation during deceleration may extend the deceleration time.

 Automatic measurement of the load characteristics reference (Load

characteristics measurement mode) (Pr.1480)

• Perform measurement under actual environment with the motor connected.

• Set Pr.1487 Load characteristics minimum frequency to a value higher than the Pr.13 Starting frequency setting.

• Setting Pr.1480 Load characteristics measurement mode = "1" enables automatic measurement of the load
characteristics reference. (Load characteristics measurement mode)
• Use Pr.1486 and Pr.1487 to set the frequency band for the measurement, and set Pr.1480 = "1". After setting, when the
inverter is started, the measurement starts. (When the value set in Pr.1486 is equal to or smaller than the value set in
Pr.1487, the measurement does not start.)
• The automatically measured load characteristics reference is written in Pr.1481 to Pr.1485.
• After the measurement is started, read Pr.1480 to display the status of the measurement. If "8" appears in the tens place,
the measurement has not properly completed.

• While measuring automatically, the During load characteristics measurement (Y213) signal is output. For the Y213 signal,
set "213" (positive logic) or "313" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function
selection) to assign the function.

 • Setting "8888" in Pr.1481 to Pr.1485 enables fine adjustment of load characteristics. When setting Pr.1481 to Pr.1485 =
"8888" during operation, the load status at that point is set in the parameter (only when the set frequency is within ±2 Hz
of the frequency of the measurement point, and the SU signal is ON).

NOTE
• Even if the load measurement is not properly completed, the load characteristics fault is detected based on the load
characteristics found by the already-completed portion of the measurement.
18
• During the load characteristics measurement, the load characteristics fault detection is not performed.
• During the load characteristics measurement, linear acceleration/deceleration is performed even if the S-pattern acceleration/
deceleration is set. 19
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

20
 Setting the load characteristics reference manually (Pr.1481 to Pr.1485)
• Set Pr.1480 Load characteristics measurement mode = "0" (initial value).
• Set Pr.1486 and Pr.1487 to specify the frequency band for the measurement, and calculate the frequency as the load
characteristics reference (f2 to f4) using the following table.
• Start the inverter operation, and set Pr.1481 = "8888" during operation at the frequency of the load characteristics
reference 1 (f1). The load status at that point is set in Pr.1481 (only when the set frequency is within ±2 Hz of the frequency
of the measurement point, and the SU signal is ON).
• Set load references in Pr.1482 to Pr.1485 in the same way as Pr.1481.

NOTE
• When inputting values directly in Pr.1481 to Pr.1485 under V/F control, input the load meter monitored values at the frequency
of each load characteristics reference.
• When inputting values directly in Pr.1481 to Pr.1485 under Advanced magnetic flux vector control, Real sensorless vector
control, Vector control, or PM sensorless vector control, input the motor torque value monitored at the frequency of each load

  Setting example
• The load characteristics are calculated from the parameter setting and the output frequency.
• A setting example is as follows. The reference value is linearly interpolated from the parameter settings. For example, the
reference when the output frequency is 30 Hz is 26%, which is linearly interpolated from values of the reference 2 and the
reference 3.
Reference Frequency Load reference
Load characteristics reference 1 f1: Load characteristics minimum frequency (Pr.1487) = 10 Hz Pr.1481 = 15%
Load characteristics reference 2 f2 = (f5 - f1)/4 + f1 = 22.5 Hz Pr.1482 = 20%
Load characteristics reference 3 f3 = (f5 - f1)/2 + f1 = 35 Hz Pr.1483 = 30%
Load characteristics reference 4 f4 = (f5 - f1) × 3/4 + f1 = 47.5 Hz Pr.1484 = 60%
Load characteristics reference 5 f5: Load characteristics maximum frequency (Pr.1486) = 60 Hz Pr.1485 = 100%

NOTE
• When the load reference is not set for five points, the load characteristics value is determined by linear interpolation of the set
load reference values only. If there is only one load reference setting, the set load reference is used as the load reference all
through the range.

 Load fault detection setting (Pr.1488 to Pr.1491)

• When the load is deviated from the detection width set in Pr.1488 Upper limit warning detection width, the Upper limit
warning detection (LUP) signal is output. When the load is deviated from the detection width set in Pr.1489 Lower limit
warning detection width, the Lower limit warning detection (LDN) signal is output. At the same time, the Load fault
warning (LDF) appears on the operation panel.
• For the LUP signal, assign the function by setting "211" (positive logic) or "311" (negative logic) in any parameter from
Pr.190 to Pr.197 (Output terminal function selection). For the LDN signal, assign the function by setting "212" (positive
logic) or "312" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function selection).
• When the load is deviated from the detection width set in Pr.1490 Upper limit fault detection width, the protective
function (E.LUP) is activated and the inverter output is shut off. When the load is deviated from the detection width set in
Pr.1491 Lower limit fault detection width, the protective function (E.LDN) is activated and the inverter output is shut off.

11.13 Load characteristics fault detection
 • To prevent the repetitive on/off operation of the signal due to load fluctuation near the detection range, Pr.1492 Load
status detection signal delay time / load reference measurement waiting time can be used to set the delay time. Even
when a fault is detected out of the detection range once, the warning is not output if the characteristics value returns to the
11
normal range from a fault state within the output delay time.

The Overspeed occurrence (E.OS) is activated when the motor speed exceeds the overspeed detection level. This function
prevents the motor from accidentally speeding over the specified value, due to an error in parameter setting, etc.

Pr. Name Initial value Setting range Description

If the motor rotation speed exceeds the speed set in Pr.374,
0 to 590 Hz
overspeed (E.OS) occurs, and the inverter output is shut off.

12.1 Speed indication and its setting change to rotations per minute
 Displayed unit switchover (Pr.37, Pr.53, and Pr.505)
• The rotation speed or machine speed can be displayed for monitoring or used for parameter setting instead of the 11
frequency by using Pr.53.
• To display the machine speed, set Pr.37 to the value which corresponds to the speed of machine operated at the frequency
set in Pr.505. 12
For example, when Pr.505 is set to 60 Hz and Pr.37 is set to "1000", the operation panel indicates "1000" as the monitor
value of machine speed while the output frequency is 60 Hz. "500" is displayed while the output frequency is 30 Hz.
• The operation panel indicates the upper 4 digits when the rotation speed or machine speed is displayed. For example, 13
when the internal value "1770.950" is monitored, the operation panel indicates "1770".

The item set in Pr.505 is consistently a frequency (Hz).
When Pr.81 (Pr.454) = "9999", the number of motor poles is regarded as 4.
17
NOTE
• The inverter's output frequency is displayed as synchronous speed under V/F control. The displayed value is "actual motor
speed" + "motor slip". When Advanced magnetic flux vector control, Real sensorless vector control, or PM sensorless vector
18
control is selected, the actual motor speed (estimated value by motor slip calculation) is used. When the encoder feedback
control or Vector control is selected, the actual motor speed from the encoder is used.
• To change the main monitor of the operation panel (operation panel main display), refer to Pr.52. 19
• Since the panel display of the operation panel or enclosure surface operation panel (FR-PA07) is in 4 digits, the monitor value
of more than "9999" is displayed as "----". Display the frequency on the operation panel when a value equal to or more than
10000 r/min needs to be monitored or set.
• The displayed machine speed is the value converted from the frequency. Therefore, the setting value and read value may
20
fluctuate due to rounding during the conversion.
• When using the machine speed display for the parameter unit (FR-PU07), do not change the speed with the up/down key if a
set speed above 65535 is displayed. The set speed may become an undetermined value.
• For details on the displayed unit switchover when a communication protocol or a communication option is used, refer to the
Instruction Manual (Communication) or the Instruction Manual of the communication option.

CAUTION
• Make sure to set the running speed and the number of motor poles.
Otherwise, the motor might run at extremely high speed, damaging the machine.

 Monitoring and resetting cumulative power (Pr.170, Pr.891)

• When the cumulative power is monitored (Pr.52 = "25"), the output power monitor value is added up and is updated in 100
17
ms increments.
• The values are stored in EEPROM every 10 minutes. The values are also stored in EEPROM at power OFF (when the FR-
E8DS is not installed) or inverter reset.
18
• Increments and ranges of monitoring on the PU or via communication are as follows (when Pr.891 = "0 or 9999").

*1 Power is measured in the range of 0 to 99999.99 kWh, and displayed in 4 digits. After the watt-hour meter (cumulative power counter) reaches
"99.99" (999.99 kWh), the meter displays values in 0.1 increments such as "100.0" (1000.0 kWh). Use Pr.891 to shift the decimal point position
when the monitored value becomes equal to or higher than 10000 kWh.
*2 Power is measured in the range of 0 to 99999.99 kWh, and displayed in 5 digits. After the watt-hour meter (cumulative power counter) reaches
"999.99" (999.99 kWh), the meter displays values in 0.1 increments such as "1000.0" (1000.0 kWh). Use Pr.891 to shift the decimal point position
when the monitored value becomes equal to or higher than 100000 kWh.

• The decimal point position on the watt-hour meter can be shifted to left. The number of digits to be shifted is equal to the
setting of Pr.891 Cumulative power monitor digit shifted times. For example, when Pr.891 = "2", the cumulative power
value 1278.56 kWh is displayed as 12.78 (in 100 kWh increments) on the operation panel, or displayed as 12 on a display
used for monitoring via communication.
• When Pr.891 = "0 to 4", the meter stops at the maximum number. When Pr.891 = "9999", the meter returns to 0 and the
counting starts again.
• The cumulative power can be monitored as 32-bit data via communication by setting Pr.52 = "77 to 80". The maximum
monitored value is 42949672 kWh in 1 kWh increments or 42949672.94 kWh in 0.01 kWh increments. Pr.891 setting is
invalid while 32-bit cumulative power is monitored. (For details on communication for 32-bit cumulative power monitor, refer
to the Instruction Manual (Communication) or the Instruction Manual of the communication option.)
• Writing "0" in Pr.170 clears the cumulative power monitor.

NOTE
• When Pr.170 is read just after "0" has been written in Pr.170, the setting "9999" or "10" is displayed.

  Monitoring cumulative energization time (Pr.563)
• When the cumulative energization time is selected as a monitor item (Pr.52 = "20"), the counter of cumulative energization
time since the inverter shipment accumulated every hour is displayed.
• One hour is displayed as "0.001", and the value is counted up to "65.53".
• The EEPROM is updated every minute until the cumulative energization time reaches one hour, and then the EEPROM is
updated every 10 minutes. The EEPROM is also updated at power OFF (when the FR-E8DS is not installed).
• When the cumulative energization time counter reaches 65535, it starts from 0 again. The number of times the cumulative
energization time counter reaches 65535 can be checked with Pr.563.

NOTE
• The cumulative energization time does not increase if the power is turned OFF after less than an hour.

 Actual operation time monitoring (Pr.171, Pr.564)

• On the actual operation time monitoring (Pr.52 = "23"), the inverter running time is added up every minute. (Time is not
added up during a stop.)
• One hour is displayed as "0.001", and the value is counted up to "65.53".
• The values are stored in EEPROM every 10 minutes. The EEPROM is also updated at power OFF (when the FR-E8DS is
not installed).
• When the cumulative energization time counter reaches 65535, it starts from 0 again. The number of times the actual
operation time counter reaches 65535 can be checked with Pr.564.
• Setting "0" in Pr.171 clears the actual operation time meter.

NOTE
• The actual operation time does not increase if the cumulative running time before power OFF is less than an hour.
• Once "0" is set in Pr.171, the setting of Pr.171 is always turned to "9999" afterwards. Setting "9999" does not clear the actual
operation time meter.

 Hiding the decimal places for the monitors (Pr.268)

• The numerical figures after a decimal point displayed on the operation panel may fluctuate during analog input, etc. The
decimal places can be hidden by selecting the decimal digits with Pr.268.
Pr.268 setting Description
9999 (initial value) No function
For the first or second decimal places (0.1 increments or 0.01 increments) of the monitor, numbers
0 in the first decimal place and smaller are rounded to display an integral value (1 increments). The
monitor value equal to or smaller than 0.99 is displayed as 0.
When monitoring with the second decimal place (0.01 increments), the 0.01 decimal place is
1 dropped and the monitor displays the first decimal place (0.1 increments). When monitoring with the
first decimal place, the display will not change.

NOTE
• The number of readout digits of the cumulative energization time (Pr.52 = "20"), actual operation time (Pr.52 = "23"),
cumulative energy (Pr.52 = "25"), and cumulative energy saving (Pr.52 = "51") does not change.

However, the frequency meter needle may not deflect to full-scale if the calibration resistor is connected. In this case, perform calibration using
the operation panel or parameter unit.
*2 In the initial setting, 1 mA full-scale and 1440 pulses/s terminal FM are used at 60 Hz.

• Calibrate the output via terminal FM in the following procedure.

1. Connect an indicator (frequency meter) across terminals FM and SD on the inverter. (Note the polarity. Terminal FM
is positive.)

2. When a calibration resistor has already been connected, adjust the resistance to "0" or remove the resistor.

3. Set a monitor item in Pr.54 FM terminal function selection. (Refer to page 358.)
When the output frequency or inverter output current is selected on the monitor, set the output frequency or current
value at which the output signal will be 1440 pulses/s, using Pr.55 Frequency monitoring reference or Pr.56
Current monitoring reference beforehand. Normally, at 1440 pulses/s the meter deflects to full-scale.

4. If the meter needle does not point to maximum even at maximum output, calibrate it with C0 (Pr.900).

12.4 Adjustment of terminal FM and terminal AM
 NOTE
• When outputting an item such as the output current, which cannot reach a 100% value easily by operation, set Pr.54 to "21" 11
(reference voltage output) and calibrate. A pulse train of 1440 pulses/s are output via terminal FM.
• When Pr.310 Analog meter voltage output selection = "21", the output via terminal FM cannot be calibrated. For details of
Pr.310, refer to the FR-A8AY E kit Instruction Manual.
• The wiring length to terminal FM should be 200 m at maximum.
12
• The initial value of the calibration parameter C0 (Pr.900) is set to 1 mA full-scale and 1440 pulses/s terminal FM pulse train
output at 60 Hz. The maximum pulse train output of terminal FM is 2400 pulses/s.
• When connecting a frequency meter between terminals FM and SD and monitoring the output frequency, it is necessary to 13
change Pr.55 to the maximum frequency, since the FM terminal output will be saturated at the initial value when the maximum
frequency reaches 100 Hz or greater.

14
 Calibration procedure for terminal FM when using the operation panel

12.4 Adjustment of terminal FM and terminal AM
363
  Terminal AM calibration (C1 (Pr.901)) (AM type only)
• Terminal AM is initially set to provide a 10 VDC output in the full-scale state of the corresponding monitor item. The
calibration parameter C1 (Pr.901) AM terminal calibration allows the output voltage ratio (gains) to be adjusted according
to the meter scale. Note that the maximum output voltage is 10 VDC.

Inverter
AM

10VDC

• Calibrate the output via terminal AM in the following procedure.

1. Connect a 0-10 VDC indicator (frequency meter) across terminal AM and terminal 5 on the inverter. (Note the
polarity. Terminal AM is positive.)

2. Set a monitor item in Pr.158 AM terminal function selection. (Refer to page 358.)
When the output frequency or inverter output current is selected on the monitor, set the output frequency or current
value at which the output signal is 10 V, using Pr.55 or Pr.56 beforehand.

3. If the meter needle does not point to maximum even at maximum output, calibrate it with C1 (Pr.901).

NOTE
• When outputting an item such as the output current, which cannot reach a 100% value easily by operation, set Pr.158 to "21"
(reference voltage output) and calibrate. A voltage of 10 VDC is output via terminal AM.
• When Pr.306 Analog output signal selection = "21", the output via terminal AM cannot be calibrated. For details on Pr.306,
refer to the FR-A8AY E kit Instruction Manual or the FR-E8AXY E Kit Instruction Manual.
• Use Pr.290 Monitor negative output selection to enable negative signal output via terminal AM. The output voltage range
is -10 to +10 VDC. Calibrate the maximum positive value output via terminal AM.

 Calibration when 0 V is output via terminal AM (Pr.1200) (AM type only)

• When 0 is output via terminal AM, use Pr.1200 AM output offset calibration to calibrate the meter. If the meter needle
does not point to 0 while 0 is output via terminal AM, set a value in Pr.1200 so that the needle points to 0.
• Set a larger value in Pr.1200 when the needle points a minus output voltage while the 0 is output via terminal AM. Set a
smaller value in Pr.1200 when the needle points a plus output voltage while the 0 is output via terminal AM.

 Adjusting the response of terminal AM (Pr.867) (AM type only)

• Use Pr.867 to adjust the output voltage response of the terminal AM in the range of 0 to 5 seconds.
• Increasing the setting stabilizes the output via terminal AM more but reduces the response level. (Setting "0" sets the
response level to 6 ms.)

data.
*2 On the LCD operation panel or the parameter unit, a readout is displayed in units of kilowatt-hours (kW).

NOTE 17
• The operation panel have a 4-digit display. This means, for example, that a monitored value up to "99.99" is displayed in 0.01
increments and a monitor value of 100 or more is displayed in 0.1 increments as "100.0". The maximum monitored value
displayed is "9999".
• The parameter unit have a 5-digit display. This means, for example, that a monitored value up to 999.99 is displayed in 0.01
18
increments and a monitor value of 1000 or more is displayed in 0.1 increments as "1000.0". The maximum monitored value
displayed is "99999".
• The maximum monitored value via communication is 65535 when Pr.898 Power saving cumulative monitor clear = "9999". 19
The maximum monitored value on monitoring in 0.01 increments is "655.35", and that on monitoring in 0.1 increments is
"6553.5".

 Power saving real-time monitoring ([1 Power saving], [2 Power saving
rate])
• During [1 Power saving] monitoring, an energy saving effect (power difference) of using the inverter as compared to the
commercial power supply operation is calculated and displayed on the main monitor.
• In the following cases, the monitored value of [1 Power saving] is "0".
The result of calculating the saved power is negative value.
DC injection brake works.
The motor is not connected with the inverter (monitored value of output current is 0 A).

• On [2 Power saving rate] monitoring, the rate of the saved power considering the consumed power (estimate) during the
power supply operation as 100% is displayed when Pr.895 Power saving rate reference value is set to "0". When Pr.895
is set to "1", the rate of the saved power with respect to the setting of Pr.893 Energy saving monitor reference (motor
capacity) that is referenced as 100% is displayed.

 Average power saving monitoring ([3 Average power saving], [4 Average

power saving rate], [5 Average power cost savings])
• The average power saving monitors are displayed by setting a value other than 9999 in Pr.897 Power saving monitor
average time.
• On [3 Average power saving] monitoring, the average hourly energy saving every preset time period is displayed.

• On [4 Average power saving rate] monitoring, the average hourly monitored value of [2 Power saving rate] is displayed
when Pr.895 Power saving rate reference value is set to "0 or 1".
• On [5 Average power cost savings] monitoring, a monetary value of the average hourly energy saving ([3 Average
power saving] × Pr.896 setting) is displayed when the unit price, power cost per kilowatt (hour), is set in Pr.896 Power
unit cost.

 Cumulative energy saving monitoring ([6 Power saving amount], [7

Power cost saving], [8 Annual power saving amount], [9 Annual power
cost savings])
• The digit of the cumulative energy monitored value can be moved to the right by the number set in Pr.891 Cumulative
power monitor digit shifted times. For example, when Pr.891 = "2", the cumulative power value 1278.56 kWh is
displayed as 12.78 (in 100 kWh increments) on the operation panel, or displayed as 13 on a display used for monitoring
via communication. When Pr.891 = "0 to 4" and the cumulative energy reaches more than the upper limit of readout, the
readout peaks out at the upper limit, which indicates that moving digit is necessary. When Pr.891 = "9999" and the
cumulative energy reaches more than the upper limit of readout, cumulative value is reset to 0 and the metering restarts.
The readout of other items in the cumulative energy saving monitoring peaks out at the upper limit of readout.
• With the monitored value of [6 Power saving amount], a cumulative energy saving during a desired time period can be
measured. Follow this procedure.

1. Set "10" or "9999" in Pr.898 Power saving cumulative monitor clear.

2. Change the setting of Pr.898 to "0" when you want to start measuring the energy saving. The cumulative value is
cleared and the cumulative energy saving meter restarts.

3. Change the setting of Pr.898 to "1" when you want to stop measuring the energy saving. The meter stops and the
cumulative value is fixed.

NOTE
• The cumulative value of energy saving is refreshed every hour. This means that the last cumulative value is displayed at a
restart of the inverter and the cumulative meter restarts if the time elapsed between turning OFF and re-turning ON of the
inverter is shorter than an hour. (In some cases, the cumulative energy value may decrease.)

• Select the pattern of the commercial power supply operation from among four patterns (discharge damper control (fan),
suction damper control (fan), valve control (pump) and commercial power drive), and set it in Pr.894 Control selection
during commercial power-supply operation. 12
• Set the motor capacity (pump capacity) in Pr.893 Energy saving monitor reference (motor capacity).
• Refer to the following graph to find the rate of power consumption (%) during commercial power supply operation based
on the selected pattern and the rate of motor rotations per minute with respect to the rated speed (the result of dividing the 13
present output frequency by Pr.3 Base frequency setting).

• The estimated input power (kW) for the commercial power supply operation is calculated from the motor capacity set in 18
Pr.893, the setting of Pr.892 Load factor, and the rate of power consumption using the following formula.

NOTE
• If the output frequency rises to the setting of Pr.3 Base frequency or higher, it stays at a constant value because the rotations

per minute cannot rise higher than the power supply frequency during commercial power supply operation.

 Annual energy saving and its monetary value (Pr.899)

• When the operation time rate (ratio of the time period in year when the inverter drives the motor) [%] is set in Pr.899, the
annual energy saving effect can be estimated.
• When the inverter is operated in specific patterns, the estimate annual energy saving can be calculated by measuring the
energy saving in a certain period.
• Refer to the following procedure to set the operation time rate.

1. Estimate the average operation time per day (h/day).

2. Calculate the operation days per year (days/year) using the following formula: Average operation days per month ×
12 (months).

3. Calculate the annual operation time (h/year) from values determined in Step 1 and Step 2, using the following
formula.
Annual operation time (h/year) = average time (h/day) × number of operation days (days/year)

4. Calculate the operation time rate using the following formula, and set it in Pr.899.
Annual operation time (h/year)
Operation time rate (%) = × 100(%)
24 (h/day) × 365 (days/year)

12. (M) Item and Output Signal for Monitoring

12.5 Energy saving monitoring
369
 NOTE
• Setting example for operation time rate: In the case where the average operation time per day is about 21 hours and the
average operation days per month is 16 days.
Annual operation time = 21 (h/day) × 16 (days/month) × 12 (months) = 4032 (h/year)

4032 (h/year)
Operation time rate (%) = × 100(%) ＝ 46.03%
24 (h/day) × 365 (days/year)

Therefore, set 46.03% in Pr.899.

• Calculate the annual energy saving from the value of [3 Average power saving] cumulated according to the setting of
Pr.899 Operation time rate (estimated value).

With Pr.898 = 10 or 9999, average power Pr.899

Annual power saving amount (kWh/year) = × 24h × 365 days ×
saving (kW) during cumulative period 100

• When the power cost per hour is set in Pr.896 Power unit cost, the annual energy cost savings can be monitored.
The annual energy cost savings is determined by calculation using the following formula.
Annual power cost saving = annual power saving amount (kWh/year) × Pr.896

NOTE
• During regenerative driving, substitute the output power during the commercial power supply operation for the saved power
(therefore, input power = 0).

reached.
• To use the SU signal, set "1" (positive logic) or "101" (negative logic) in any parameter from Pr.190 to Pr.197 (Output

 Output frequency detection (FU (FB) signal, Pr.42, Pr.43)

• The Output frequency detection (FU) signal and the Speed detection (FB) signal are output when the output frequency
reaches or exceeds the Pr.42 setting.
• The FU signal is useful for applying or releasing electromagnetic brake, etc. Use the Inverter running (RUN) signal when
releasing the brake from the motor with a brake under encoder feedback control. (The brake may not be released when
the FU signal is used.)
• The FU signal is output when the output frequency (frequency command) reaches the set frequency. The FB signal is
output when the detected actual speed (estimated speed under Real sensorless vector control, or feedback value under
Vector control) of the motor reaches the set frequency. The FU signal and the FB signal are output at the same manner
under V/F control or Advanced magnetic flux vector control or during the encoder feedback control operation.
• The frequency detection dedicated to motor rotation in reverse direction is enabled by setting the frequency in Pr.43. This
setting is useful when the timing of the electromagnetic braking during forward rotation operation (for example, during lifting
up in the lifts operation) is different from that during reverse rotation operation (lifting down).

• The fault "E.OLT" displays and the inverter output shuts off if the torque limit operation causes the frequency to drop to the
frequency set in Pr.865 and the output torque to surpass the value set in Pr.874 OLT level setting for three seconds or 18
longer in the speed control mode under Real sensorless vector control, Vector control, or PM sensorless vector control.
• For the LS signal, set "34" (positive logic) or "134" (negative logic) in any parameter from Pr.190 to Pr.197 (Output

 Output current detection (Y12 signal, Pr.150, Pr.151, Pr.166, Pr.167)
• The output current detection function is useful for overtorque detection.
• If the inverter output during inverter running remains higher than the Pr.150 setting for the time set in Pr.151 or longer, the
17
Output current detection (Y12) signal is output.
• When the Y12 signal turns ON, the ON state is retained for the time set in Pr.166.
• When Pr.166 = "9999", the ON state is retained until the next start-up of the inverter. 18
• Setting Pr.167 = "1" while the Y12 signal is ON does not cause the fault E.CDO. The Pr.167 setting becomes valid after
the Y12 signal is turned OFF.
• For the Y12 signal, set "12" (positive logic) or "112" (negative logic) in any parameter from Pr.190 to Pr.197 (Output 19

 • If the inverter output current decreases, slippage due to gravity may occur, especially in a lift application, because the
motor torque decreases. To prevent this, the Y13 signal can be output from the inverter to apply the mechanical brake
when the output current falls below the Pr.152 setting.
• For the Y13 signal, set "13" (positive logic) or "113" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign the function to an output terminal.
• Use Pr.167 to select the inverter operation at the time when Y13 signal turns ON, whether the inverter output stops or the

NOTE
• This function is enabled during online or offline auto tuning.
• The response time of the Y12 and Y13 signals is approximately 0.1 seconds. However, the response time varies according to
the load condition.
• When Pr.152 = "0", the zero current detection function is disabled.
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

CAUTION
• The setting of the zero current detection level should not be too low, and the setting of the zero current detection time
should not be too long. Doing so may cause the signal for the zero current detection not to be output when the output
current is very low and the motor torque is not generated.
• A safety backup such as an emergency brake must be provided to prevent machines or equipment in hazardous
conditions even if the Zero current detection is used.

 Remote output setting (REM signal, Pr.496, Pr.497)

• The signal assigned to each of the output terminal can be turned ON or OFF according to the settings of Pr.496 and Pr.497.
The signal assigned to each of the remote output terminal can be turned ON or OFF through communication.
• For the Remote output (REM) signal, set "96" (positive logic) or "196" (negative logic) in any parameter from Pr.190 to
Pr.192, and Pr.197 (Output terminal function selection) to assign the function to an output terminal.
• Refer to the following figures to check correspondences between the bit and the actual terminal. When "1" is set in the bit
corresponding to the terminal to which the REM signal assigned by setting a number in Pr.496 and Pr.497 each, the signal
turns ON (or OFF in negative logic setting). Also, setting "0" allows the signal to turn OFF (or ON in negative logic setting).
• For example, when Pr.190 RUN terminal function selection = "96" (positive logic) and "1" (H01) is set in Pr.496, the REM
signal assigned to terminal RUN turns ON.

 Remote output data retention (REM signal, Pr.495)

• When the inverter power is reset (or a power failure occurs) while Pr.495 = "0 (initial value) or 10", the REM signal setting
is cleared. (The ON/OFF state of the signal assigned to each terminal is determined by the settings in Pr.190 to Pr.192,
and Pr.197.) The settings in Pr.496 and Pr.497 are reset to "0".
• When Pr.495 = "1 or 11", the remote output data is stored in EEPROM before the inverter power is turned OFF. This means
that the signal output setting after power restoration is the same as that before the power was turned OFF. However, when
Pr.495 = "1", the data during an inverter reset (terminal reset or reset request via communication) is not saved.

NOTE
• To enable terminal 4, turn ON the AU signal.
• Set the parameters and the switch settings so that they agree. Incorrect setting may cause a fault, failure, or malfunction.
• Use Pr.125 (Pr.126) (frequency setting gain) to change the maximum output frequency at the input of the maximum output
frequency command voltage (current). At this time, the command voltage (current) need not be input. Also, the acceleration/
deceleration time, which is a slope up/down to the acceleration/deceleration reference frequency, is not affected by the change
in Pr.73 setting.
• To input frequency through terminal 4, set "0" (initial value) in Pr.858.
• Always calibrate the input after changing the voltage/current input signal with Pr.73 (Pr.267) and the voltage/current input
selection switch.
• When Pr.561 PTC thermistor protection level ≠ "9999", terminal 2 is not used for the analog frequency command.

 Running with analog input voltage

• For the frequency setting signal, input 0 to 5 VDC (or 0 to 10 VDC) between terminals 2 and 5. The 5 V (10 V) input is the
maximum output frequency.
• The power supply 5 V (10 V) can be input by either using the internal power supply or preparing an external power supply.
The internal power supply is 5 VDC output via terminal 10.

13.3 Response level of analog input and noise elimination
 Analog speed command input time constant (Pr.822, Pr.832)
• Use Pr.822 Speed setting filter 1 to set the primary delay filter time constant to the external speed command (analog 11
input command). Increase the setting of the time constant to allow delays in follow-up of the speed command or when the
analog input voltage is unstable.

motors.
• Pr.832 Speed setting filter 2 is enabled when the RT signal is ON.

 Analog torque command input time constant (Pr.826, Pr.836) 13

• Use Pr.826 Torque setting filter 1 to set the primary delay filter time constant to the external torque command (analog
input command). Increase the setting of the time constant to allow delays in follow-up of the torque command or when the
analog input voltage is unstable.
14
• Use Pr.836 Torque setting filter 2 to change the time constant to use one inverter to switch operation between two or
more motors.
• Pr.836 Torque setting filter 2 is enabled when the RT signal is ON.
15
 Analog speed command input offset adjustment (Pr.849)
• Use this parameter to set a range in which the motor is stopped for prevention of incorrect motor operation in a very low 16
speed rotation when the speed command is an analog input (voltage/current) via terminal 2.
• Example) Voltage command given

 Changing the frequency for the maximum analog input (Pr.125, Pr.126)
• Use Pr.125 (Pr.126) to change the frequency setting (gain) for the maximum analog input voltage (current).
(C2 (Pr.902) to C7 (Pr.905) settings need not be changed.)

 Analog input bias/gain calibration (C2 (Pr.902) to C7 (Pr.905))

• The "bias" and "gain" functions serve to adjust the relationship between a setting input signal and the output frequency. A
setting input signal is such as a 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mADC signal externally input to set the output
frequency.
• Set the bias frequency of the terminal 2 input using C2 (Pr.902). (It is initially set to the frequency at 0 V.)
• Use Pr.125 to set the output frequency to the frequency command voltage (current) set by Pr.73 Analog input selection.

13.6 Input terminal function selection
 NOTE
• The same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR. 11
• The priority of the frequency command given by the external signals is as follows: JOG operation (JOG/JOG2 signal) > stop-
on-contact control (RL/RT signal) > multi-speed operation (RL/RM/RH/REX signal) > PID control (X14 signal) > terminal 4
analog input (AU signal) > pulse train input (option FR-E8AXY) > 16-bit digital input (option FR-A8AX) > terminal 2 analog
input. Note that stop-on-contact control is disabled when PID control is enabled.
12
• When the Inverter run enable (X10) signal is not assigned, or when the PU operation external interlock (X12) signal is not
assigned while Pr.79 Operation mode selection = "7", the MRS signal performs the same function.
• The same terminals are used to assign the multi-speed (7-speed) setting and the remote setting. The multi-speed setting and 13
the remote setting cannot be assigned separately.
• When the terminal assignment is changed using Pr.178 to Pr.189 (Input terminal function selection), wiring may be
mistaken due to different terminal name and signal contents, or may affect other functions. Set parameters after confirming
the function of each terminal. 14

• To input the MRS signal, set "24" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign
the function.
• The response time of the MRS signal is within 2 ms (except for the FR-E800-SCE).
• The MRS signal is used in the following cases.
Application Description

• When Pr.17 = "4 or 5", the MRS signal input from an external terminal is normally closed (NC contact), and the MRS signal
input from communication is normally open (NO contact). This function is useful to perform operation via communication
while keeping the ON state of the MRS signal input from the external terminal. 12

NOTE 18
• When using an external terminal to input the MRS signal, the MRS signal shuts off the output in any of the operation modes.
• The MRS signal is valid regardless of whether it is input through the external terminal or via network (except for the FR-E800-
SCE), but when the MRS signal is used as the Inverter run enable (X10) signal, input the signal through the external terminal.
• When the terminal assignment is changed using Pr.178 to Pr.189 (Input terminal function selection), wiring may be
19
mistaken due to different terminal name and signal contents, or may affect other functions. Set parameters after confirming
the function of each terminal.

*2 The start signal operation selection is available in External operation mode or when the start command source is External in the Network operation
mode.

 2-wire type (STF signal, STR signal)

• The following figure shows the 2-wire type connection.
• As an initial setting, the forward/reverse rotation signals (STF/STR) acts as both start and stop signals. Either one turned
ON will be enabled, and the operation will follow that signal. The motor will decelerate to a stop when both are turned OFF
(or both are turned ON) during the operation.
• The frequency can be set by inputting 0 to 10 VDC between the speed setting input terminals 2 and 5, or with Pr.4 to Pr.6
Multi-speed setting (high speed, middle speed, and low speed). (For the multi-speed operation, refer to page 303.)
• By setting Pr.250 = "1000 to 1100, 8888", the STF signal input becomes the start command and the STR signal input
becomes the forward/reverse command.

 NOTE
• By setting Pr.250 = "0 to 100, 1000 to 1100", the motor will coast to a stop when the start command is turned OFF. (Refer to 11
page 543.)
• The STF and STR signals are assigned to Pr.178 STF/DI0 terminal function selection and Pr.179 STR/DI1 terminal
function selection in the initial status. The STF signal can be assigned to only Pr.178 STF/DI0 terminal function selection,
and the STR signal can be assigned to only Pr.179 STR/DI1 terminal function selection.
12

 3-wire type (STF signal, STR signal, STP (STOP) signal) 13

• The following figure shows the 3-wire type connection.
• The self-holding function is enabled when the STP (STOP) signal is turned ON. In such case, the forward/reverse signal
is simply used as a start signal. (The STP (STOP) signal can be input via an external terminal only.) 14
• For the STP (STOP) signal, set "25" in any parameter from Pr.178 to Pr.184 (Input terminal function selection) to assign
the function.
• Even if a start signal (STF or STR) is turned ON and then OFF, the start command remains valid and the motor operation 15
continues. To change the rotation direction, turn the STR (STF) signal ON once and then OFF.
• In order to decelerate the motor to a stop, turn OFF the STP (STOP) signal once.

14.1 Applied motor

By setting the applied motor type, the thermal characteristic appropriate for the motor can be selected.
When using a constant-torque or PM motor, the electronic thermal O/L relay function is set according to the motor.
When the Advanced magnetic flux vector control, Real sensorless vector control, Vector control, or PM sensorless vector
control is selected, the motor constant necessary for control (for SF-PR, SF-PR-SC, SF-JR, SF-HR, SF-JRCA, SF-HRCA, SF-
V5RU (1500 r/min series), GM-[], GM-DZ, GM-DP, MM-GKR, or EM-A) is also selected at the same time.

• When the SF-PR motor is selected (Pr.71 = "70 or 73"), the Pr.0 Torque boost setting is automatically changed to enable
output of the 6 Hz 150% torque under V/F control by setting Pr.81 Number of motor poles according to the number of
the SF-PR motor poles.

NOTE
• When selecting the automatic change of torque boost for the SF-PR motor, set Pr.14 Load pattern selection = "0 (initial
value)".
• When the Pr.0 setting is changed from its initial value, the automatic change is not performed.

NOTE
• When the Pr.0 and Pr.12 settings are changed from their initial values, the automatic change is not performed. 15
• When the SF-PR motor is selected (Pr.71 = "70 or 73"), the output current may become large due to a small load by setting
Pr.81 Number of motor poles according to the number of the SF-PR motor poles.
• When the SF-PR motor is used, the output current tends to increase compared with the case where the SF-JR or SF-HR motor 16
is used. Depending on the load conditions, the output current may increase even though the torque boost value has been
automatically changed. When the protective function such as the electronic thermal O/L relay (E.THT, E.THM) or stall
prevention (OL, E.OLT) is activated, adjust the Pr.0 Torque boost according to the load.

CAUTION 18
• Make sure to set this parameter correctly according to the motor used. Incorrect setting may cause the motor and the
inverter to overheat and burn.

*5 To perform offline auto tuning for the 400 V class 0.1 kW Mitsubishi Electric geared motor (GM-[]), set "1803" in Pr.71 (Pr.450).

• The setting is valid under Advanced magnetic flux vector control, Real sensorless vector control, or Vector control.
• By using the offline auto tuning function, the optimum operation characteristics are obtained for a motor other than Mitsubishi
Electric standard efficiency motors (SF-JR 0.2 kW or higher), high-efficiency motors (SF-HR 0.2 kW or higher), Mitsubishi
Electric constant-torque motors (SF-JRCA 4P, SF-HRCA 0.2 kW to 7.5 kW), Mitsubishi Electric high-performance energy-
saving motor (SF-PR), Mitsubishi Electric high-performance energy-saving motor with encoder (SF-PR-SC), Mitsubishi
Electric Vector control dedicated motor (SF-V5RU (1500 r/min series)), Mitsubishi Electric geared motor (GM-[]), or Mitsubishi
Electric inverter-driven geared motor for encoder feedback control (GM-DP), such as an induction motor of other
manufacturers or SF-JRC, GM-DZ, or with a long wiring length (exceeding 30 m as a reference).
• Tuning is enabled even when a load is connected to the motor.
• Reading/writing of the motor constants tuned by offline auto tuning are enabled.
• The offline auto tuning status can be monitored on the operation panel or the parameter unit.

 Before performing offline auto tuning

Check the following points before performing offline auto tuning:
• Check that a value other than "9999" is set in Pr.80 and Pr.81, and Advanced magnetic flux vector control, Real sensorless
vector control, or Vector control is selected (with Pr.800). (Refer to page 115.)
• Check that a motor is connected. (Check that the motor is not rotated by an external force during tuning.)
• Select a motor with the rated current equal to or less than the inverter rated current.
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque
accuracies may deteriorate due to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter
rated current. (For details on the inverter rated current, refer to the inverter rated specifications in the Instruction Manual
(Connection).)
• Tuning is not available for a high-slip motor, high-speed motor, or special motor.
• The maximum frequency is 400 Hz.
• Tuning is enabled even when a load is connected to the motor. The motor may run slightly. Fix the motor securely with a
mechanical brake, or before tuning, make sure that it is safe even if the motor rotates. (Caution is required especially in
vertical lift applications.) Note that even if the motor runs slightly, tuning performance is unaffected.
• Offline auto tuning is not performed correctly when the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) is inserted
between the inverter and motor. Be sure to remove it before performing tuning.
• Make sure to connect the encoder to the motor without coaxial misalignment for Vector control. Speed ratio must be 1:1.

NOTE
• When Pr.11 DC injection brake operation time = "0" or Pr.12 DC injection brake operation voltage = "0", offline auto
tuning is performed at the initial setting of Pr.11 or Pr.12.
• Offline auto tuning is not performed when position control is selected (Pr.800 = "3 or 4" (when the MC signal is ON) or "5"
(when the MC signal is OFF)).
• If "wye connection" or "delta connection" is incorrectly selected in Pr.71, Advanced magnetic flux vector control, Real
sensorless vector control, and Vector control are not performed properly.
• To perform offline auto tuning for the 400 V class 0.1 kW Mitsubishi Electric geared motor (GM-[]), set "1803" in Pr.71 (Pr.450).

• For tuning accuracy improvement, set the following parameters when the motor constants are known in advance.

 Performing tuning

• Before performing tuning, check the monitor display of the operation panel or parameter unit if the inverter is in the state ready
for tuning. The motor starts by turning ON the start command while tuning is unavailable.

• In the PU operation mode, press the RUN key on the operation panel or the FWD/REV key on the parameter unit.
In the External operation, turn ON the start command (STF signal or STR signal). Tuning starts.

14.2 Offline auto tuning
 NOTE
• Satisfy the required inverter start conditions to start offline auto tuning. For example, stop the input of the MRS signal. 11
• To force tuning to end, use the MRS or RES signal or the STOP/RESET key on the PU.
(Turning OFF the start signal (STF signal or STR signal) also ends tuning.)
• During offline auto tuning, only the following I/O signals are valid (initial value).
Input terminals <effective signals>: MRS, RES, STF, STR, S1, and S2
12
Output terminals: RUN, FU, FM, AM, ABC, and SO
• When the rotation speed and the output frequency are selected for terminals FM and AM, the progress status of offline auto
tuning is output in 15 steps from FM and AM (in the standard model). 13
• Do not perform ON/OFF switching of the Second function selection (RT) signal during offline auto tuning. Auto tuning will not
be performed properly.
• Since the Inverter running (RUN) signal turns ON when tuning is started, pay close attention especially when a sequence which
releases a mechanical brake by the RUN signal has been designed. 14
• When executing offline auto tuning, input the operation command after switching ON the main circuit power (R/L1, S/L2, T/L3)
of the inverter.
• While Pr.79 Operation mode selection = "7", turn ON the PU operation external interlock (X12) signal for tuning in the PU 15
operation mode.
• Setting offline auto tuning (Pr.96 = "1") will make pre-excitation invalid.

16
• During tuning, the monitor is displayed on the PU as follows.

• Note: Offline auto tuning time (with the initial setting)

Offline auto tuning setting Time
Pr.96 (Pr.463) = "1" About 25 to 100 s. (The time depends on the inverter capacity and motor type.)
• When offline auto tuning ends, press the STOP/RESET key on the PU during PU operation. In the External operation
mode, turn OFF the start signal (STF signal or STR signal).
This operation resets the offline auto tuning, and the monitor display of the operation panel returns to normal.
(Without this operation, next operation cannot be started.)

NOTE
• The motor constants measured once during offline auto tuning are stored as parameters and their data are held until offline
auto tuning is performed again. However, the tuning data is cleared when performing All parameter clear.
• Changing Pr.71 (Pr.450) after tuning completion will change the motor constant. For example, if "3" is set in Pr.71 after tuning
is performed with Pr.71 = "0", the tuning data becomes invalid. To use the tuned data, set "0" again in Pr.71.

14. (C) Motor Constant Parameters

 • If offline auto tuning has ended in error (see the following table), motor constants are not set. Perform an inverter reset and
restart tuning.

9 Inverter protective function operation Make the setting again.

91 The current limit (stall prevention) function is activated.

Check for the power supply voltage fluctuation.
92 The converter output voltage fell to 75% of the rated voltage. Check the Pr.83 Rated motor voltage (Pr.456 Rated
second motor voltage) setting.
Calculation error. Check the Pr.83 and Pr.84 settings.
93
The motor is not connected. Check the motor wiring and make the setting again.
• When tuning is ended forcibly by pressing the STOP/RESET key or turning OFF the start signal (STF or STR) during
tuning, offline tuning does not end properly. (The motor constants have not been set.)
Perform an inverter reset and perform tuning again.
• When the rated power supply of the motor is 200/220 V (400/440 V) 60 Hz, set the rated motor current multiplied by 1.1 in
Pr.9 Electronic thermal O/L relay after tuning is complete.
• For a motor with a PTC thermistor, thermal protector, or other thermal detection, set "0" (motor overheat protection by
inverter invalid) in Pr.9 to protect the motor from overheating.

NOTE
• An instantaneous power failure occurring during tuning will result in a tuning error. After power is restored, the inverter starts
normal operation. Therefore, when the STF (STR) signal is ON, the motor starts forward (reverse) rotation.
• Any fault occurring during tuning is handled as in the normal operation. However, if the retry function is set, no retry is
performed.
• The set frequency monitor displayed during the offline auto tuning is 0 Hz.

CAUTION
• Note that the motor may start running suddenly.
• For performing offline auto tuning with the motor rotating in vertical lift applications, etc., caution is required to avoid falling
due to insufficient torque.

 Changing the motor constants

• The motor constants can be set directly when the motor constants are known in advance, or by using the data measured
during offline auto tuning.
• According to the Pr.71 (Pr.450) setting, the range of the motor constant parameter setting values and units can be
changed. The changed settings are stored in the EEPROM as the motor constant parameters.

 Changing the motor constants (when setting the Pr.92 and Pr.93 motor

14.3 Offline auto tuning for a PM motor 11

PM

The offline auto tuning enables the optimal operation of a PM motor. Two types of the offline auto tuning, motor constant tuning
12
and position accuracy compensation gain tuning, are available.
• Motor constant tuning: Automatic measurement of motor constants enables optimal operation of motors for PM sensorless
vector control even when motor constants vary or when the wiring distance is long.
13
• Position accuracy compensation gain tuning: When an EM-A motor is used, automatic measurement of the position
compensation amount improves the positioning accuracy.
• Tuning may be disabled depending on the motor characteristics. 14
For the offline auto tuning under Advanced magnetic flux vector control, Real sensorless vector control, and Vector control,

• The settings are valid under PM sensorless vector control.
• The offline auto tuning enables the operation with IPM motors and SPM motors. (When a PM motor other than the MM-GKR
or EM-A is used, always perform offline auto tuning.) 20
• Tuning is not available for S-PM geared motors (GV-S series).
• Even when the MM-GKR or EM-A motor is used, offline auto tuning is required when the wiring length is long (exceeding 30
m as a reference), when the wiring length is changed, or when positioning accuracy for the EM-A motor need to be improved.
• Tuning is enabled even when a load is connected to the motor.
• Reading/writing of the motor constants tuned by offline auto tuning are enabled.
• The offline auto tuning status can be monitored on the operation panel or the parameter unit.

 Before performing offline auto tuning

Check the following points before performing offline auto tuning:
• Check that PM sensorless vector control is selected. Note that the motor constant tuning is invalid during position control.
(Refer to page 115.)
• Check that a motor is connected. (Check that the motor is not rotated by an external force during tuning.)
• Select a motor with the rated current equal to or less than the inverter rated current.
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque
accuracies may deteriorate due to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter
rated current. (For details on the inverter rated current, refer to the inverter rated specifications in the Instruction Manual
(Connection).)
• The maximum frequency under PM sensorless vector control is 400 Hz.
• Tuning is enabled even when a load is connected to the motor. The motor may run slightly. Fix the motor securely with a
mechanical brake, or before tuning, make sure that it is safe even if the motor rotates. (Caution is required especially in
vertical lift applications.) Note that even if the motor runs slightly, tuning performance is unaffected.
• It is recommended that the position accuracy compensation gain tuning is performed for the motor alone. Tuning is not
available under certain load conditions, such as when the motor shaft is locked or when the inertia is too large.

NOTE
• The position accuracy compensation gain tuning is available only for the first motor.

 Performing tuning

• Before performing tuning, check the monitor display of the operation panel or parameter unit if the inverter is in the state ready
for tuning. The motor starts by turning ON the start command while tuning is unavailable.

• In the PU operation mode, press the RUN key on the operation panel or the FWD/REV key on the parameter unit.
In the External operation, turn ON the start command (STF signal or STR signal). Tuning starts.

444 14. (C) Motor Constant Parameters

14.3 Offline auto tuning for a PM motor
 NOTE
• Satisfy the required inverter start conditions to start offline auto tuning. For example, stop the input of the MRS signal. 11
• To force tuning to end, use the MRS or RES signal or the STOP/RESET key on the PU. (Turning OFF the start signal (STF
signal or STR signal) also ends tuning.)
• During offline auto tuning, only the following I/O signals are valid (initial value).
Input terminals <effective signals>: MRS, RES, STF, STR, S1, and S2
12
Output terminals: RUN, FM, AM, ABC, and SO
• When the rotation speed and the output frequency are selected for terminals FM and AM, the progress status of offline auto
tuning is output in 15 steps from FM and AM (in the standard model). 13
• Do not perform ON/OFF switching of the Second function selection (RT) signal during offline auto tuning. Auto tuning will not
be performed properly.
• A motor with 14 or more poles cannot be tuned.
• Since the Inverter running (RUN) signal turns ON when tuning is started, pay close attention especially when a sequence which 14
releases a mechanical brake by the RUN signal has been designed.
• When executing offline auto tuning, input the operation command after switching ON the main circuit power (R/L1, S/L2, T/L3)
of the inverter. 15
• While Pr.79 Operation mode selection = "7", turn ON the PU operation external interlock (X12) signal for tuning in the PU
operation mode.
• Setting offline auto tuning (Pr.96 = "1, 11, or 301") will make pre-excitation invalid.

 • When offline auto tuning ends, press the STOP/RESET key on the PU during PU operation. In the External operation
mode, turn OFF the start signal (STF signal or STR signal). This operation resets the offline auto tuning, and the monitor
display of the operation panel returns to normal. (Without this operation, next operation cannot be started.)

NOTE
• The motor constants measured once during offline auto tuning are stored as parameters and their data are held until offline
auto tuning is performed again. However, the tuning data is cleared when performing All parameter clear.
• Changing Pr.71 after tuning completion will change the motor constant. For example, if the Pr.71 setting is changed to "8093"
after tuned with Pr.71 = "8090", the tuning data become invalid. To use the tuned data, set "8090" again in Pr.71.

• If offline auto tuning has ended in error (refer to the following table), motor constants or position accuracy compensation
gain values are not set. Perform an inverter reset and perform tuning again.

tuning, offline tuning does not end properly. (The motor constants or position accuracy compensation gain values have not
been set.)
Perform an inverter reset and perform tuning again.

NOTE
• An instantaneous power failure occurring during tuning will result in a tuning error.
After power is restored, the inverter starts normal operation. Therefore, when the STF (STR) signal is ON, the motor starts
forward (reverse) rotation.
• Any fault occurring during tuning is handled as in the normal operation. However, if the retry function is set, no retry is
performed even when a protective function that performs a retry is activated.
• The set frequency monitor displayed during the offline auto tuning is 0 Hz.

CAUTION
• Note that the motor may start running suddenly.

 NOTE
• If "9999" is set in the motor constant parameters, tuning data will be invalid and the inverter internal constant is used.
• To change a motor induced voltage constant of PM motors, the setting in Pr.706 Induced voltage constant (phi f) or Pr.738
Second motor induced voltage constant (phi f) must be changed. If the constant after the change exceeds the setting range
of Pr.706 or Pr.738 (0 to 5000 mV (rad/s)), set Pr.1412 Motor induced voltage constant (phi f) exponent or Pr.1413
Second motor induced voltage constant (phi f) exponent. Set a value in the exponent n in the formula, Pr.706 (Pr.738) ×
10n [mV (rad/s)], to set the induced voltage constant (phi f).
• When Pr.71 (Pr.450) = "8093 or 9093", or Pr.1412 (Pr.1413) = "9999", the motor induced voltage constant is as set in Pr.706

NOTE
• As the motor constants measured in the offline auto tuning have been converted into internal data (****), refer to the following
setting example when making setting. (The value displayed has been converted into a value for internal use. Therefore, simple
addition of a value to the displayed value does not bring the desired effect.)
Setting example: to slightly increase the Pr.90 value (5%)
When "2516" is displayed for Pr.90, set 2642 (2516 × 1.05 = 2641.8) in Pr.90.
• If "9999" is set in the motor constant parameters, tuning data will be invalid and the inverter internal constant is used.
• To change a motor induced voltage constant of PM motors, the setting in Pr.706 Induced voltage constant (phi f) or Pr.738
Second motor induced voltage constant (phi f) must be changed. If the constant after the change exceeds the setting range
of Pr.706 or Pr.738 (0 to 5000 mV (rad/s)), set Pr.1412 Motor induced voltage constant (phi f) exponent or Pr.1413
Second motor induced voltage constant (phi f) exponent. Set a value in the exponent n in the formula, Pr.706 (Pr.738) ×

 Online auto tuning at startup (Pr.95 (Pr.574) = "1") 18

• By promptly tuning the motor status at startup, accurate operation without being affected by motor temperature is achieved.
Also high torque can be provided at very low speed and stable operation is possible.
• Make sure to perform offline auto tuning before performing online auto tuning. 19
Operating procedure

 NOTE
• To perform the online auto tuning at startup for a lift, consider using a brake sequence function for the brake opening timing
at a start. The tuning takes about 500 ms at the most after starting. However, during this time, it is possible that not enough
torque is provided and caution is required to prevent the object from dropping. (Refer to page 456).
• Perform online auto tuning at startup when the motor is stopped.
• The online auto tuning is disabled when the MRS signal is being input, the setting speed is Pr.13 Starting frequency or lower
(V/F control, Advanced magnetic flux vector control), an inverter fault is occurring, or the inverter's startup condition is not
satisfied.
• Online auto tuning does not operate during deceleration and restart from DC injection brake operation.
• It is disabled during JOG operation.
• If automatic restart after instantaneous power failure is selected, automatic restart is prioritized. (Online auto tuning at startup
is not performed during frequency search.)
• Zero current detection and output current detection are enabled during online auto tuning.
• The RUN signal is not output during online auto tuning. The RUN signal is turned ON at operation startup.
• If the time between the inverter stop and restart is within four seconds, tuning is performed at startup but its result will not be
applied.

 Start-time tuning completion (Y39) signal

• The start-time tuning completion (Y39) signal can be output when the start-time tuning completes.
• To use the Y39 signal, set "39" (positive logic) or "139" (negative logic) in any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign the function to an output terminal.

15.1 Brake sequence function

Magnetic flux Sensorless Vector

This function outputs operation timing signals of the mechanical brake from the inverter, such as for lift applications.
This function is useful in preventing load slippage at a start due to poor mechanical brake timing and overcurrent alarm in stop
status and enable secure operation.

15. (A) Application Parameters

15.1 Brake sequence function
457
 NOTE
• The automatic restart after instantaneous power failure function, orientation control, and emergency drive function do not
operate when brake sequence is selected.
• To use this function, set the acceleration/deceleration time to 1 second or longer.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) or Pr.190 to Pr.197 (Output
terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal.

 Setting the brake sequence operation

• Set Pr.292 Automatic acceleration/deceleration = "7 or 8 (braking sequence operation)".
To ensure sequence operation, it is recommended to use with Pr.292 = "7" (with brake opening completion signal input).
• Set "15" in any parameter from Pr.178 to Pr.189 (Input terminal function selection), and assign the Brake opening
completion (BRI) signal to an input terminal.
• Set "20" (positive logic) or "120" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function
selection), and assign the Brake opening request (BOF) to an output terminal.
• Use Pr.639 Brake opening current selection to select whether the output current or the motor torque is used as a
reference for the brake opening operation.
• Under Real sensorless vector control or Vector control, use Pr.640 Brake operation frequency selection to select
whether the frequency command or the actual motor speed (estimated value) is used as a reference for brake closing
operation. If the brake operation timing is different from the motor speed because of the load, set Pr.640 = "1 (brake
operation with the actual motor speed (estimated value))".
• Under Advanced magnetic flux vector control or encoder feedback control, the frequency command is used as a reference
for brake operation regardless of the Pr.640 setting.

NOTE
• Under torque control, the brake sequence function is disabled.

 Operation with brake opening completion signal input (Pr.292 = "7")

• When the start signal is input to the inverter, the inverter starts running, and when the output frequency reaches the
frequency set in Pr.278 Brake opening frequency and the output current or the motor torque is equal to or greater than
the Pr.279 Brake opening current setting, the brake opening request signal (BOF) is output after the time set in Pr.280
Brake opening current detection time. The Brake opening completion (BRI) signal is input, and the output frequency is
increased to the set speed after the set time in Pr.281 Brake operation time at start.
• When the inverter decelerates to the frequency set in Pr.282 Brake operation frequency during deceleration, the inverter
turns OFF the brake opening request signal (BOF) and decelerates further to the frequency set in Pr.278. After
electromagnetic brake operation completes and the inverter recognizes the turn OFF of the BRI signal, the inverter holds
the frequency set in Pr.278 for the time set in Pr.283 Brake operation time at stop. And after the time set in Pr.283
passes, the inverter decelerates again. The inverter outputs is shut off when the frequency reaches Pr.13 Starting
frequency setting or 0.5 Hz, whichever is lower.

NOTE
• Even if the brake sequence operation has been selected, inputting the JOG signal (JOG operation) during an inverter stop

the brake sequence function is invalid during operation.

 Protective function 20
• If one of the following faults occurs while the brake sequence function is enabled, the inverter enters a fault status, shuts
off output, and turns OFF the brake opening request signal (BOF).

 NOTE
• During deceleration, inverter output is shut OFF when the frequency reaches Pr.13 Starting frequency or 0.5 Hz, whichever
is lower. For Pr.278 Brake opening frequency, set a frequency equal to or higher than the Pr.13 setting or 0.5 Hz.
• Pr.285 Overspeed detection frequency is valid under encoder feedback control (used with the Vector control compatible
option) even if a value other than "7 or 8" is set in Pr.292 Automatic acceleration/deceleration.
• Setting Pr.278 too high activates the stall prevention and may cause E.MB4.
• E.MB4 occurs when the time period calculated by adding Pr.280 to the acceleration time from Pr.13 to Pr.278 reaches or
exceeds 2 seconds.

15.2 Stop-on-contact control 11

12
Magnetic flux Sensorless

To ensure accurate positioning at the upper limit, etc. of a lift, stop-on-contact control causes the mechanical brake to close
while the motor creates a holding torque to keep the load in contact with a mechanical stopper, etc.
This function suppresses vibration that is likely to occur when the load is stopped upon contact in lift applications, thereby
ensuring reliable and highly accurate positioning stop.

• When both the RT and RL signals are switched ON, the inverter enters the stop-on-contact control, and operation is
performed at the frequency set in Pr.6 independently of the preceding speed.
• Setting Pr.270 = "11" disables stall prevention stop (E.OLT) during stop-on-contact control (with both RL and RT signals
ON).

NOTE
• The priority of the frequency command given by the external signals is as follows: JOG operation (JOG/JOG2 signal) > stop-
on-contact control (RL/RT signal) > multi-speed operation (RL/RM/RH/REX signal) > terminal 4 analog input (AU signal) >
pulse train input (option FR-E8AXY) > 16-bit digital input (option FR-A8AX) > terminal 2 analog input.
• By increasing the Pr.275 setting, the low-speed (stop-on-contact) torque increases, but overcurrent fault (E.OC[]) may occur
or the machine may oscillate in stop-on-contact status.
• The stop-on-contact function is different from the servo-lock function, and if used to stop or hold a load for an extended period,
this function can cause the motor to overheat. After a stop, immediately switch to a mechanical brake to hold the load.
• Under the following operating conditions, the stop-on-contact function is invalid:
PU operation (Pr.79), JOG operation (JOG signal), PU + External operation (Pr.79), PID control function operation (Pr.128),
Remote setting function operation (Pr.59), Automatic acceleration/deceleration operation (Pr.292), Start time tuning,
Orientation control function operation
• When performing stop-on-contact control during encoder feedback control, encoder feedback control is invalid due to a
transition to the stop-on-contact control mode.

• Setting Pr.592 Traverse function selection = "1 or 2" enables the traverse function.
• Assigning the Traverse function selection (X37) signal to the input terminal enables the traverse function only when the
X37 signal is ON. (When the X37 signal is not assigned, the traverse function is always available. When the Network
operation mode is selected, the traverse function is always available regardless of ON/OFF state of the X37 signal.) To
input the X37 signal, set "37" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function to a terminal.

• The motor accelerates to the set frequency f0 according to the normal Pr.7 Acceleration time at turn ON of the start
command (STF or STR).
• When the output frequency reaches f0 and the X37 signal turns ON, the inverter begins traverse operation and accelerates
to f0 + f1. The acceleration time at this time is according to the Pr.596 setting. (If the X37 signal turns ON before the output
frequency reaches f0, traverse operation begins after the output frequency reaches f0.)
• After the inverter accelerates the motor to f0 + f1, this is compensated with f2 (f1 × Pr.594), and the motor decelerates to
f0 - f1. The deceleration time at this time is according to the Pr.597 setting.
• After the inverter decelerates the motor to f0 - f1, this is compensated with f3 (f1 × Pr.595), and the motor accelerates again
to f0 + f1.
• When the X37 signal turns OFF during traverse operation, the inverter accelerates/decelerates the motor to f0 according
to the normal acceleration/deceleration time (Pr.7, Pr.8). If the start command (STF or STR) is turned OFF during traverse
operation, the inverter decelerates the motor to a stop according to the normal deceleration time (Pr.8).

15.3 Traverse function
 NOTE
• If the set frequency (f0) and traverse operation parameters (Pr.593 to Pr.597) are changed during traverse operation, this is 11
applied in operations after the output frequency reaches f0 before the change was made.
• If the output frequency exceeds the setting of Pr.1 Maximum frequency or Pr.2 Minimum frequency during traverse
operation, the output frequency is clamped at the maximum/minimum frequency when the set pattern exceeds the maximum/
minimum frequency. (The output frequency is not clamped at minimum frequency during JOG operation.)
12
• When the traverse function and S-pattern acceleration/deceleration (Pr.29 ≠ "0") are selected, S-pattern acceleration/
deceleration operation occurs only in the range operated at the normal acceleration/deceleration time (Pr.7, Pr.8).
Acceleration/deceleration during traverse operation is performed linearly. 13
• If stall prevention activates during traverse operation, traverse operation stops and normal operation begins. When stall
prevention operation is completed, the inverter accelerates/decelerates the motor to f0 at the normal acceleration/deceleration
time (Pr.7, Pr.8). After the output frequency reaches f0, the traverse operation begins again.
• If the value of the amplitude inversion compensation amount (Pr.594, Pr.595) is too large, an overvoltage trip or stall 14
prevention occurs, and pattern operation cannot be performed as set.
• The traverse function is disabled during orientation control.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions. 15

 Anti-sway control operation (Pr.1073)

• Setting Pr.1073 Anti-sway control operation selection = "1" enables anti-sway control. (Anti-sway control is not
performed during DC injection brake operation (zero speed control / servo lock) operation.)
• During operation under anti-sway control, the travel distance becomes longer. Input a stop command earlier to avoid a
collision with an obstacle.
• When the Anti-sway control disabled (X54) signal is assigned to an input terminal using Pr.178 to Pr.189 (Input terminal
function selection), turning ON the X54 signal can disable anti-sway control.
• A deceleration to stop without anti-sway control is applied for stopping as a result of PU stop, a deceleration stop due to a
communication error, the Emergency stop (X92) signal input, or an emergency stop via communication.

• During operation of the power failure time deceleration-to-stop function, or when the automatic restart after instantaneous
power failure is enabled (Pr.57 ≠ "9999"), the anti-sway control is disabled.

 Swinging frequency setting (Pr.1074 to Pr.1079)

• Set a swinging frequency in Pr.1074 Anti-sway control frequency. The swinging frequency is used as a notch filter
frequency. Lower the response level of speed control in the frequency band with the width set in the Pr.1076 Anti-sway
control width by the gain set in the Pr.1075 Anti-sway control depth.

466 15. (A) Application Parameters

15.4 Anti-sway control
 • A deeper notch depth has a greater effect in reducing mechanical resonance but makes the phase delay larger, which may
increase swinging. Adjust the depth by starting from the shallowest value.
11
Setting 3 2 1 0
Gain (depth) -4 dB (shallow) -8 dB -14 dB -∞ (deep)

• If the Pr.1076 setting is too large (the width is too wide), the response level of speed control drops, and the system may 12
become unstable.
• After setting Pr.1074 = "9999", set the crane rope length in the Pr.1077 Rope length, the trolley weight in the Pr.1078
Trolley weight, and the weight of an object in the Pr.1079 Load weight. Then, anti-sway control is performed using a 13
swinging frequency estimated by the inverter. When Pr.1078 = "0" or Pr.1079 = "0", anti-sway control is performed using
a swinging frequency estimated by the inverter according to the Pr.1077 setting.

 Delay time for brake operation of anti-sway control (Pr.1072)

14
• Set the time from when the output frequency becomes the Pr.10 DC injection brake operation frequency or less to when

• When anti-sway control is enabled, regeneration avoidance, shortest acceleration/deceleration, the traverse function, and 20
deceleration check are disabled regardless of whether the X54 signal is ON or OFF.
• Do not set anti-sway control and droop control together.

Remove jumpers connecting terminals PC and S1 and terminals PC and S2, and wire terminals as follows. Insulate the lead wire of the resistor,
for example by applying a contraction tube, and shape the wires so that the resistor and its lead wire do not touch other cables. Caulk the lead
wire securely together with the thermal protector input line using a 2-wire blade terminal. (Do not subject the lead wire's bottom area to an
excessive pressure.)
The thermal protector can be connected to the standard model and the Ethernet model only.
To use a terminal as terminal OH, assign the OH (External thermal relay input) signal to an input terminal. (Set "7" in any parameter from Pr.178

 Setting
• When the Orientation command (X22) signal is turned ON during operation after the parameters are set, the motor is
decelerated to the orientation switchover speed. Then, the inverter calculates the orientation stop distance, further
decelerates the motor and the motor enters the orientation state (servo lock). The Orientation complete (ORA) signal is
output when the motor is within the orientation complete width.

 Setting I/O signals

The output is in LOW state when the orientation stop can be made within the orientation complete width while
Orientation the start signal and X22 signal are input (ON).
ORA
complete For the ORA signal output, set "27" (positive logic) or "127" (negative logic) in any parameter from Pr.190 to
Pr.192, and Pr.197 to assign the function.
The output is in LOW state when the orientation stop cannot be made within the orientation complete width
while the start signal and X22 signal are input (ON).
ORM Orientation fault
For the ORM signal output, set "28" (positive logic) or "128" (negative logic) in any parameter from Pr.190 to
Pr.192, and Pr.197 to assign the function.

 Orientation at the running status (under V/F control, Advanced magnetic

1. When the Orientation command (X22) signal turns ON, the motor speed decelerates to Pr.351 Orientation speed.
(Pr.351 is initially set to 2 Hz.)

15. (A) Application Parameters

15.5 Orientation control
471
 2. After the speed reaches the orientation speed, the speed further decreases to the Pr.352 Creep speed as soon as
the current position pulse reaches the Pr.353 Creep switchover position.
(Pr.352 is initially set to 0.5 Hz, Pr.353 is initially set to "511".)

3. Moreover, as soon as the current position pulse reaches Pr.354 Position loop switchover position, control is
changed to the position loop. (Pr.354 is initially set to "96".)

4. After the motor moves into the position loop, the motor decelerates and stops by the DC injection brake as soon as
the current position pulse reaches the Pr.355 DC injection brake start position. (Pr.355 is initially set to "5".)

5. When the motor stops in the in-position width set in Pr.357 Orientation in-position zone, the Orientation complete
(ORA) signal is output after Pr.363 Completion signal output delay time. If the motor does not stop within the in-
position width because of external force or other factors, the ORA signal turns OFF after the time set in Pr.363.
(Pr.357 is initially set to "5", Pr.363 is initially set to 0.5 s.)

6. If the orientation is not completed continuously in Pr.365 Orientation limit after passing the creep switchover
position*1, the Orientation fault (ORM) signal is output.

7. After the orientation starts, if the motor is stopped by external force or other factors before reaching the in-position
width and the ORA signal is not output, the ORM signal is output after Pr.364 Encoder stop check time. If the motor
is moved out of the in-position width by external force or other factors after the ORA signal has been output once,
the ORA signal turns OFF after the time period set in Pr.363. If the orientation is not completed within the time period
set in Pr.364, the ORM signal is output.

8. If the ORA and ORM signals have been output once, but the start signal (STF or STR) is turned OFF while the X22
signal is ON, the ORA or ORM signal is output again after Pr.366 Recheck time.

9. The ORA and ORM signals cannot be output while the X22 signal is OFF.
*1 It means that the current position pulse reaches the creep switchover absolute position and moves in the direction to the start command.
Creep switchover absolute position is defined as follows.
Forward rotation: Stop position command - DC injection brake start position (Pr.355) - Creep switchover position (Pr.353)
Reverse rotation: Stop position command + DC injection brake start position (Pr.355) + Creep switchover position (Pr.353)

NOTE
• When the orientation command turns OFF while the start signal is ON, the speed accelerates to the command speed.

• Turning ON the start signal after turning ON the Orientation command (X22) signal increases the motor speed to the Pr.351
Orientation speed, and then the same orientation operation is performed as the operation shown in "Orientation at the
running status". 12
• Note that the DC injection brake operates without increasing to the orientation speed when the following formula is

NOTE 16
• The following are precautions for the orientation operation under V/F control or Advanced magnetic flux vector control.
• Couple the encoder with the motor shaft or with the shaft that stops the main shaft at the specified position. Couple it with
the speed ratio of 1:1 and without any mechanical looseness.
• The DC injection brake operates at orientation stop. Release the DC injection brake as soon as possible (within several
17
seconds), as continuous operation of the DC injection brake will cause the motor to overheat, leading to burnout.
• Because the servo lock function is not available after orientation stop, provide a holding mechanism, such as a mechanical
brake or knock pin, when secure holding of the main shaft is required. 18
• To ensure correct positioning, the encoder must be set in the proper rotation direction, and the A and B phases must be
connected correctly.
• If the pulse signal from the encoder stops due to encoder signal loss or other factors during orientation, the Orientation fault
(ORM) signal may be output.
19
• When performing orientation control, enable the DC injection brake (refer to page 536). When the DC injection brake is
disabled, orientation operation cannot be completed.
• When orientation control is performed, the DC injection brake operates regardless of the External DC injection brake 20
operation start (X13) signal even when Pr.11 DC injection brake operation time = "8888" (DC injection brake external
selection).
• To terminate orientation, the start signal (STF or STR) must be first switched OFF, and then the Orientation command (X22)
signal must be switched OFF. As soon as this X22 signal is switched OFF, orientation control ends. (Depending on the
Pr.358 Servo torque selection setting, the orientation status continues if the X22 signal remains ON even if the DC
injection brake is released by turning OFF the start signal. Because of this, the orientation status on the monitor does not
show "0".)
• When the retry function of Pr.358 Servo torque selection is selected, the retry operation is performed three times including
the first orientation.
• When performing orientation control, properly set Pr.350 Stop position command selection. If the values set are incorrect,
proper orientation control will not be performed.
• Orientation control is disabled under the following conditions:
During auto tuning, during PID control, when the automatic acceleration/deceleration function is enabled, when the brake
sequence function is enabled, or when the second function is enabled

474 15. (A) Application Parameters

15.5 Orientation control
 NOTE
• When the orientation command turns OFF while the start signal is ON, the motor accelerates to the command speed. 11
• When the motor shaft stops outside of the set setting range of the stop position, the motor shaft is returned to the stop position
by the servo torque function (if enough torque is generated).

12
a. Servo torque function until output of the Orientation complete signal
Select whether or not servo torque is available using Pr.358 Servo torque selection. Servo torque is not generated if the
current position pulse is in between the orientation stop position and DC injection brake start position. The shaft is fixed
13
using the DC injection brake, and when the motor exits the width by external force or other factors, the servo torque is
generated to move the motor back within the width. Once the Orientation complete (ORA) signal is output, the operation

b.
is performed as described in d.
Retry function
14
Select retry function using Pr.358. Note that the retry function cannot be used together with the servo torque function. If
the motor shaft does not stop within the in-position zone when the motor stop is checked, orientation operation is
performed again by the retry function. This retry function is performed three times including the first orientation. The
15
maximum retry number is three. (The Orientation fault (ORM) signal is not output during retry operation.)
c. Frequency compensation when the motor stops outside the orientation complete width
When the motor stops before entering the in-position width due to external force or other factors, the output frequency is 16
increased to move the shaft to the orientation stop position. The output frequency is gradually increased to the Pr.352
Creep speed. This function cannot be used with the retry function.
d. DC injection brake and servo torque selection when the motor exits the in-position zone after output of the ORA signal 17
If the motor exits the in-position width, select the setting either to fix the shaft with the DC injection brake or by returning
the motor to the orientation stop position with the servo torque.
e. Turning OFF the Orientation complete (ORA) signal when the orientation operation is ended. 18
When ending the orientation operation, first turn OFF the start (STF or STR) signal, and then turn OFF the Orientation
command X22 signal. At this time, select when to turn OFF the ORA signal from either the time the start signal is turned
OFF or the time the X22 signal is turned OFF. 19
f. Complete signal when the motor exits the in-position zone after output of the ORA signal
Select to turn OFF the ORA signal or to keep the ORA signal ON (the ORM signal is not output) when the motor exits the
in-position width. 20
 Position loop gain (Pr.362) (V/F control, Advanced magnetic flux vector
control)
• When the servo torque function is selected using Pr.358 Servo torque selection, the output frequency for generating
servo torque gradually increases to the Pr.352 Creep speed according to the slope set in Pr.362 Orientation position
loop gain.
• Although the operation becomes faster when the value is increased, hunting may occur in the machine.

  Orientation to the current rotation direction (Pr.393 = "0 (initial value)")
(Vector control)
• When the Orientation command (X22) signal is input, the motor speed decelerates from the running speed to Pr.351
Orientation speed. At the same time, the orientation stop position command is read in. (The stop position command is
determined by the setting of Pr.350 Stop position command selection.)

Speed Speed [t]

(forward (reverse

X22 OFF ON X22 OFF ON

ORA OFF ON ORA OFF ON

• When the orientation switchover speed is reached, the encoder Z phase pulse is confirmed, and the control changes from
speed control to position control (Pr.362 Orientation position loop gain).
• The distance to the orientation stop position is calculated at switching of the control, and the motor decelerates to a stop
with a set deceleration pattern (Pr.399 Orientation deceleration ratio) and enters the orientation (servo lock) state.
• Once in the Pr.357 Orientation in-position zone, the Orientation complete (ORA) signal is output.
• The home position can be moved using Pr.361 Position shift.

CAUTION
• If the X22 signal is turned OFF while the start signal is input, the motor accelerates toward the speed of the current speed
command. To stop the motor, turn the Forward rotation (Reverse rotation) signal OFF.

 Orientation to the forward rotation direction (Pr.393 = "1") (Vector

control)
• This method is used to improve the stopping precision and maintain the mechanical precision when the backlash is large.
• If the motor is running in forward, it executes an orientation stop with the same method as "orientation to the current rotation
direction".
• If the motor is running in reverse, the motor decelerates and rotates to the forward rotation direction, and then orientation
stop is executed.

 NOTE
• The following are precautions for the orientation operation under V/F control. 11
• Couple the encoder with the motor shaft that stops the shaft at the specified position. Couple it with the speed ratio of 1:1
and without any mechanical looseness.
• To ensure correct positioning, the encoder must be set in the proper rotation direction, and the A and B phases must be
connected correctly.
12
• If the pulse signal from the encoder stops due to encoder signal loss or other factors during orientation, orientation may not
be completed.
• The X13 signal is valid until the speed reaches the orientation speed and the encoder Z phase pulse is detected. 13
• To terminate orientation, the start signal (STF or STR) must be first switched OFF, and then the X22 signal must be switched
OFF. As soon as this X22 signal is switched OFF, orientation control ends.
• When performing orientation control, properly set Pr.350 Stop position command selection.
If the values set are incorrect, proper orientation control will not be performed.
14
• Orientation control is disabled under the following conditions:
During auto tuning, during PID control, when the automatic acceleration/deceleration function is enabled, when the brake
sequence function is enabled, or when the second function is enabled 15
• If Signal loss detection (E.ECT) is activated while the X22 signal is ON, check for a break in the cable of the Z phase of the
encoder.

16
 Servo rigidity adjustment (Pr.362, Pr.396 to Pr.398) (Vector control)
• To increase the servo rigidity*1 during orientation stop using Pr.396 Orientation speed gain (P term) or Pr.397
17
Orientation speed integral time, make adjustments with the following procedures.

1. Increase the Pr.362 Orientation position loop gain setting value to the extent that rocking*2 does not occur during 18
orientation stop.

2. Increase Pr.396 and Pr.397 at the same rate.

Normally, adjust Pr.396 in the range from 10 to 100, and Pr.397 from 0.1 to 1.0 s. 19
(Note that these do not need to be set to the same rate.)
<Example>
When the Pr.396 setting value is multiplied by 1.2, divide the Pr.397 setting value by 1.2. 20
If vibration occurs during orientation stop, the scale cannot be raised any higher.

3. Pr.398 Orientation speed gain (D term) is the lag/advance compensation gain.

The limit cycle*3 can be prevented by increasing the value, and operation can be stopped stably. However, the
torque decreases in relation to the position deviation, and the motor stops with deviation.
*1 Servo rigidity: The response when a position control loop is configured.
When the servo rigidity is raised, the holding force increases and operation becomes stable, but vibration occurs more easily.
When the servo rigidity is lowered, the holding force decreases, and the settling time increases.
*2 Rocking: Movement in which return occurs when the stopping position is exceeded.
*3 Limit cycle: A phenomenon that generates ± continuous vibration centering on the target position.

• Application of lag/advance control and PI control

PI control can be applied by setting Pr.398 = "0". Normally, use the lag/advance control. PI control should be used when using
a machine with a high spindle static friction torque requires a stop position accuracy.
• During orientation control, gain cannot be adjusted using Pr.820 Speed control P gain 1, Pr.821 Speed control integral time
1, and Pr.698 Speed control D gain.

15. (A) Application Parameters

15.5 Orientation control
477
  Pr.399 Orientation deceleration ratio (initial value: 20) (Vector control)
• Make adjustments with the following procedures according to the orientation status. (Make adjustments in the order of a,
b, and c.)
Normally, adjust Pr.362 Orientation position loop gain in the range from 5 to 20, and Pr.399 Orientation deceleration
ratio from 5 to 50.
Condition Adjustment procedure
a. Decrease the Pr.399 setting.
Rocking occurs during stopping b. Decrease the Pr.362 setting.
c. Increase the Pr.396 and Pr.397 settings.
a. Increase the Pr.399 setting.
The orientation time is long.
b. Increase the Pr.362 setting.
a. Decrease the Pr.362 setting.
Hunting occurs during stopping
b. Decrease the Pr.396 setting and increase the Pr.397 setting.
a. Increase the Pr.396 setting and decrease the Pr.397 setting.
Low servo rigidity during stopping
b. Increase the Pr.362 setting.

NOTE
• If the orientation stop operation fails and the Excessive position fault occurs, or if the motor performs forward/reverse
reciprocation operation, review the settings of Pr.393 Orientation selection (on page 469) and Pr.359 Encoder rotation
direction (on page 468).

 Pr.351 Orientation speed (initial value: 2 Hz) (Vector control)

• Set the speed when switching between the speed control mode and the position control mode is performed under
orientation operation.
Decreasing the set speed enables stable orientation stop. Note that the orientation time increases.

(Pr.131 PID upper limit) or lower limit (Pr.132 PID lower limit), or when the deviation input exceeds the permissible value
(Pr.553 PID deviation limit).
• Choose whether to output the signals (FUP, FDN, Y48) only or to activate the protective function to output the inverter
shutoff.
• The stop action when the inverter output is shut off by the sleep function can be selected.

and protective function are not available.

 PID output suspension function (sleep function) (SLEEP signal, Pr.575 to

Pr.577)
• When a status where the output frequency after PID calculation is less than Pr.576 Output interruption detection level
has continued for the time set in Pr.575 Output interruption detection time or longer, inverter running is suspended. This
allows the amount of energy consumed in the inefficient low-speed range to be reduced.
• When the deviation (set point - measured value) reaches the PID output shutoff release level (Pr.577 setting value -1000%)
while the PID output suspension function is activated, the PID output suspension function is released, and PID control
operation is automatically restarted.
• Whether to allow motor to coast to a stop or perform a deceleration stop when sleep operation is started can be selected
using Pr.554.
• While the PID output suspension function is activated, the PID output interruption (SLEEP) signal is output. During this
time, the Inverter running (RUN) signal turns OFF and the During PID control activated (PID) signal turns ON.

 Integral stop selection when the frequency is limited (Pr.1015)

• The operation for the integral term can be selected when the frequency or the manipulated amount is limited during PID
control.
• The manipulation range can be selected.

• The frequency reaches the upper or lower limit.
• The manipulated amount reaches plus or minus 100% (Pr.1015 = "0").
• The manipulated amount reaches 0% or 100% (Pr.1015 = "2").

 PID monitor function

• This function displays the PID control set point, measured value and deviation on the operation panel, and can output these
from the terminals FM and AM.
• An integral value indicating a negative % can be displayed on the deviation monitor. 0% is displayed as 1000. (These
values cannot be output on the deviation monitor from terminals FM.)

 • Calibrating set point input
(Example: To enter the set point on terminal 2)

1. 1. Apply the input (for example, 0 V) of set point setting 0% across terminals 2 and 5.

2. Using C2 (Pr.902), enter the frequency (for example, 0 Hz) to be output by the inverter when the deviation is 0%.

3. Using C3 (Pr.902), set the voltage value at 0%.

4. Apply the input (for example, 5 V) of set point setting 100% across terminals 2 and 5.

5. Using Pr.125, enter the frequency (for example, 60 Hz) to be output by the inverter when the deviation is 100%.

6. Using C4 (Pr.903), set the voltage value at 100%.

NOTE
• When the set point is set by using Pr.133, the setting frequency of C2 (Pr.902) is equivalent to 0% and the setting frequency
of Pr.125 is equivalent to 100%.

• Measured value input calibration

1. Apply the input (for example, 4 mA) of measured value 0% across terminals 4 and 5.

2. Perform calibration by C6 (Pr.904).

3. Apply the input (for example, 20 mA) of measured value 100% across terminals 4 and 5.

4. Perform calibration by C7 (Pr.905).

NOTE
• Set the frequencies set in C5 (Pr.904) and Pr.126 to each of the same values set in C2 (Pr.902) and Pr.125.

speed operation (RL/RM/RH/REX signal) > PID control (X14 signal) > terminal 4 analog input (AU signal) > pulse train input
(option FR-E8AXY) > 16-bit digital input (option FR-A8AX) > terminal 2 analog input.
• Even if the X14 signal is ON, PID control is stopped and multi-speed or JOG operation is performed when the multi-speed
operation (RH, RM, RL, or REX) signal or JOG signal (JOG operation) is input.
12
• PID control is invalid under the following settings.
Pr.79 Operation mode selection = "6" (Switchover mode)
• To use terminal 4 input in PID control, set "0" (initial value) to Pr.858 Terminal 4 function assignment. When a value other 13
than "0", PID control is invalid.
• Changing the terminal functions with Pr.178 to Pr.189 and Pr.190 to Pr.197 may affect other functions. Set parameters after
confirming the function of each terminal.
• When PID control is selected, the minimum frequency becomes the frequency of C2 (Pr.902) and the maximum frequency 14
becomes the frequency of Pr.125.
(The Pr.1 Maximum frequency and Pr.2 Minimum frequency settings also are valid.)
• During PID operation, the remote operation function is invalid. 15
• When control is switched to PID control during normal operation, the frequency during that operation is not carried over, and
the value resulting from PID calculation referenced to 0 Hz becomes the command frequency.

starting with the letter C.

 Calibration of PID display bias and gain (C42 (Pr.934) to C45 (Pr.935))
• When both C42 (Pr.934) and C44 (Pr.935) ≠ "9999", the bias and gain values for the set point, measured value and
deviation in PID control can be calibrated.
• "Bias"/"gain" function can adjust the relation between PID displayed coefficient and measured value input signal that is
externally input. Examples of these measured value input signals are 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mADC. (The
terminals used for measured value input can be selected at Pr.128, Pr.609, Pr.610.)
• Set the value that is displayed when the PID measured value (control amount) is 0% to C42 (Pr.934) and the value that is
displayed when the PID measured value (control amount) is 100% to C44 (Pr.935).
• When both C42 (Pr.934) and C44 (Pr.935) ≠"9999" and Pr.133 is set as the set point, the setting of C42 (Pr.934) is treated
as 0%, and C44 (Pr.935) as 100%.

• There are three methods to adjust the PID display bias/gain.

Method to adjust any point by application of a current (voltage) to the measured value input terminal
Method to adjust any point without application of a current (voltage) to the measured value input terminal
Method to adjust only the display coefficient without adjustment of current (voltage)
(Refer to page 400 for details, and make the necessary adjustments by considering C7 (Pr.905) as C45 (Pr.935) and Pr.126
as C44 (Pr.935).)

 NOTE
• Always calibrate the input after changing the voltage/current input specification with Pr.73 and Pr.267, and the voltage/current 11
input selection switch.

• Take caution when the following condition is satisfied because the inverter recognizes the deviation value as a negative 12
(positive) value even though a positive (negative) deviation is given: C42 (PID bias coefficient) > C44 (PID gain coefficient).
To perform a reverse action, set Pr.128 PID action selection to forward action. Alternatively, to perform a forward action,
set Pr.128 to reverse action. In this case, the PID output shutoff release level is (1000 - Pr.577). 13
Pr.934 < Pr.935 (normal setting) Pr.934 ≥ Pr.935

Forward action Forward action setting to Pr.128 Forward action Reverse action setting to Pr.128 14
PID output shutoff release level Pr.577 - 1000 PID output shutoff release level 1000 - Pr.577
(Example) Set the following: C42 (Pr.934) = "500", C43 (Pr.934) = 20% (4 mA is applied), C44 (Pr.935) = "100", and C45
(Pr.935) = 100% (20 mA is applied). 15
When the set point = 400 and the measured value = 360, the deviation is +40 (>0), but the inverter recognizes the deviation
as -10% (<0). Because of this, operation amount does not increase in the reverse operation setting.
The operation amount increases when the forward operation is set. 16
To perform PID output shutoff release at deviation of +40 or higher, set Pr.577 = "960".

 Outline of dancer control

• Dancer control is performed by setting "40 to 43" in Pr.128 PID action selection. The main speed command is the speed
command for each operation mode (External, PU, and communication). PID control is performed by the dancer roll position
detection signal, and the control result is added to the main speed command. For the main speed acceleration/deceleration
time, set the acceleration time to Pr.44 Second acceleration/deceleration time and the deceleration time to Pr.45
Second deceleration time.

STF ON

NOTE
• Normally, set Pr.7 Acceleration time and Pr.8 Deceleration time to 0 s. When the Pr.7 and Pr.8 settings are large, dancer
control response becomes slow during acceleration/deceleration.
• If an automatic restart after instantaneous power failure is activated during dancer control, E.OC[] or E.OV[] is likely to occur.
In such case, disable the automatic restart after instantaneous power failure function (Pr.57 = "9999").

*1 When Pr.133 ≠ "9999", the Pr.133 setting is valid.

• To enable dancer control, set "40 to 43" in Pr.128 PID action selection. 20
• Dancer control is enabled only when the PID control valid (X14) signal turns ON when "14" is set in any parameter from
Pr.178 to Pr.182 (Input terminal function selection) and X14 signal is assigned. When the X14 signal is not assigned,
dancer control is enabled only by the Pr.128 setting.
• Input the main speed command (External, PU, Communication). Dancer control is also supported by the main speed
command in all operation modes.
• Input the set point between the terminals 2 and 5 (the setting can be selected using Pr.133 or Pr.609) and input the
measured value signal (dancer roll position detection signal) between the inverter terminals 4 and 5 (the setting can be
selected using Pr.610).
• The action of Pr.129 PID proportional band, Pr.130 PID integral time, Pr.131 PID upper limit, Pr.132 PID lower limit
and Pr.134 PID differential time is the same as PID control action. In the relationship between the control amount (%)
and frequency in PID control, 0% is equivalent to the frequencies set in C2 (Pr.902) and 100% is equivalent to the
frequencies set in Pr.125.

NOTE
• When Pr.128 is set to "0" or the X14 signal is OFF, regular inverter running not dancer control is performed.
• Dancer control is enabled by turning ON/OFF the bits of terminals assigned the X14 signal by RS-485 communication or over
the network.
• When dancer control is selected, set the PID output suspension function (Pr.575 Output interruption detection time =
"9999").
• When Pr.561 PTC thermistor protection level ≠ "9999", terminal 2 cannot be used for the main speed command. Terminal
2 becomes the PTC thermistor input terminal.

and 4 by Pr.73 Analog input selection or Pr.267 Terminal 4 input selection to match the specification of the input
device.
• When Pr.133 PID action set point ≠ "9999", Pr.133 is the set point. When the set point is set at Pr.133, the setting
frequency of C2 (Pr.902) is equivalent to 0% and the setting frequency of Pr.125 is equivalent to 100%.

refer to the FR-A8NC E kit Instruction Manual or the Instruction Manual (Communication). CC-Link communication is unavailable when the IP67
model is used.

NOTE
• After changing the Pr.73 or Pr.267 setting, check the voltage/current input selection switch. Incorrect setting may cause a fault,
failure or malfunction. (Refer to page 392 for the setting.)
• When terminals 2 and 4 are selected for deviation input, perform bias calibration using C3 (Pr.902) and C6 (Pr.904) to prevent
a minus voltage from being entered as the deviation input signal. Input of a minus voltage might damage devices and the
inverter.

• When ratio is selected as the additive method (Pr.128 = "42, 43"), PID calculation result × (ratio of main speed) is added 11
to the main speed. The ratio is determined by the Pr.125 Terminal 2 frequency setting gain frequency and C2 (Pr.902)
Terminal 2 frequency setting bias frequency settings. In the initial status, 0 to 60 Hz is set for 0% to 100%. Thus, 60 Hz

 Priority of main speed commands

• The priority of the frequency command given by the external signals is as follows: JOG operation (JOG/JOG2 signal) >
multi-speed operation (RL/RM/RH/REX signal) > PID control (X14 signal) > terminal 4 analog input (AU signal) > pulse
train input (option FR-E8AXY) > 16-bit digital input (option FR-A8AX) > terminal 2 analog input.
• The following is the frequency commands listed in descending order of priority when "3" is set in Pr.79 Operation mode
selection: Multi-speed setting function (RL/RM/RH/REX signal) > PID control (X14 signal) > terminal 4 analog input (AU
signal) > set frequency (digital input from the PU).
• Even if the remote operation function is selected by Pr.59 Remote function selection ≠ "0", compensation of the remote
setting frequency against the main speed is ignored. (The value is "0".)
• If the same terminal as an external input terminal having a speed command source (external terminal where a main speed
is input) is specified as the measured value input or set point input, the main speed is treated as "0".
• Setting Pr.73 ≥ 10 enables the polarity reversible operation when the PID manipulated amount is added to the main speed
command. (Polarity reversible operation of the main speed command without addition is not possible.)

 Adjustment procedure for dancer roll position detection signal

• When the input of terminal 4 is voltage input, 0 V is the lower limit position and 5 V (10 V) is the upper limit position (initial
values). When it is current input, 4 mA is the lower limit position and 20 mA is the upper limit position (initial values). When
the potentiometer has an output of 0 to 7 V, C7 (Pr.905) must be calibrated at 7 V.

(Example) To execute control at the dancer center position using a 0 to 7 V potentiometer

1. Switch the voltage/current input selection switch (switch 4) to "V", set "2" in Pr.267, and set terminal 4 input to
voltage input.

2. Input 0 V across terminals 4 and 5, and calibrate C6 (Pr.904). (The % display that is indicated at analog calibration
is not related to the % of the feedback value.)

3. Input 7 V across terminals 4 and 5, and calibrate C7 (Pr.905). (The % display that is indicated at analog calibration
is not related to the % of the feedback value.)

4. Set Pr.133 to "50%".

 NOTE
• After changing the Pr.267 setting, check the voltage/current selection switch. Incorrect setting may cause a fault, failure, or 11
malfunction. (Refer to page 392 for the setting.)
• If the Multi-speed operation (RH, RM, RL, or REX) signal, or JOG signal is input during regular PID control, PID control is
interrupted. However, at dancer control, these signals are treated as main speed commands, so PID control is continued.
• During dancer control, Pr.44 and Pr.45 (Second acceleration/deceleration time) is the parameter for setting the acceleration/
12
deceleration time for the main speed command. This function does not work as a second function.
• When the switchover mode is set by setting "6" to Pr.79, dancer control (PID control) is invalid.
• The acceleration/deceleration action of the main speed command is the same as that when the frequency is increased or 13
decreased by analog input. The SU signal sometimes stays ON even if operation is turned ON/OFF by the start signal. The
set frequency monitor is the value "main speed command + PID control" which is constantly changing.
• With the main speed setting frequency setting, acceleration/deceleration is performed for the acceleration/deceleration time
set in Pr.44 and Pr.45, and with the output frequency setting, acceleration/deceleration is performed for the acceleration/ 14
deceleration time set in Pr.7 and Pr.8. For this reason, with the output frequency, when the time set in Pr.7 and Pr.8 is longer
than the time set in Pr.44 and Pr.45, acceleration/deceleration is performed for the acceleration/deceleration time set in Pr.7
and Pr.8. 15
• The limit of the integral term is the smaller of 100% and the value after conversion of the straight line after interpolation of Pr.1
Maximum frequency by C2 (Pr.902) and Pr.125 to the PID manipulated amount.
However, note that the lower limit frequency limits the output frequency, but does not restrict the action of the integral item.

 Restart operation with frequency search (Pr.162 ="0 or 10", Pr.299) 16

• When Pr.162 = "0 (initial value) or 10", the motor speed is detected at a power restoration so that the motor can re-start
smoothly.
• The encoder also detects the rotation direction so that the inverter can re-start smoothly even during the reverse rotation. 17
• Whether or not to detect the rotation direction can be selected by Pr.299 Rotation direction detection selection at
restarting. If the motor capacity is different from the inverter capacity, set Pr.299 = "0" (no rotation direction detection).
• When the rotation direction is detected, the following operation is performed according to Pr.78 Reverse rotation 18

15.9 Automatic restart after instantaneous power failure / flying start with an induction motor
503
 NOTE
• The rotation speed detection time (frequency search) changes according to the rotation speed of the motor (maximum 1
second).
• When the inverter capacity is two ranks or more higher than the motor capacity, the overcurrent protective function (E.OC[])
is sometimes activated and prevents the inverter from restarting.
• If two or more motors are connected to one inverter, this function operates abnormally. (The inverter does not restart
successfully.)
• Because a DC injection brake is applied instantaneously at speed detection during a restart, the speed might drop if the
moment of inertia (J) of the load is small.
• If reverse operation is detected when "1" (reverse rotation disabled) is set to Pr.78, operation decelerates by reverse rotation
and then changes to forward rotation when the start command is forward rotation. The inverter does not restart when the start
command is reverse rotation.
• When the automatic restart after instantaneous power failure is performed while the motor rotates at low speed (lower than 10
Hz), the motor rotates in the same direction as that before instantaneous power failure without detecting the rotation direction
(even when Pr.299 = "1").

 Restart operation without frequency search (Pr.162 = "1 or 11")

• When Pr.162 = "1 or 11" while the encoder feedback control is disabled, reduced voltage start is used for the restart
operation. In this method, the voltage is raised gradually while keeping the output frequency level at the level before an
instantaneous power failure, regardless of the motor's coasting speed.

NOTE
• This restart method uses the output frequency that was active before the instantaneous power failure stored in memory. If the
instantaneous power failure time is 0.2 second or more, the output frequency can no longer be stored and held in memory, so
the restart is performed from Pr.13 Starting frequency (initial value: 0.5 Hz).
• During Real sensorless vector control, the operation is the same as one when Pr.162 = "0 or 10".

 Restart operation with encoder detection frequency search (Pr.162 = "1

or 11")
• When "1 or 11" is set in Pr.162 by encoder feedback control, the inverter is restarted by the motor speed and direction of
rotation that were detected by the encoder at the power restoration.

settings are invalid at this time.
• For the encoder feedback control, refer to page 559.
16
• During Real sensorless vector control, the operation is the same as one when Pr.162 = "0 or 10".

17
 Restart at every start (Pr.162 = "10 or 11")
• When "10 or 11" is set in Pr.162, a restart operation is performed at each start and automatic restart after instantaneous
power failure (after the time period set in Pr.57 elapsed). When "0 (initial value) or 1" is set in Pr.162, a restart operation 18
is performed at the first start after a power-ON, and from the second power-ON onwards, a start from the starting frequency
is performed.

 Automatic restart operation of the MRS (X10) signal 19

• The restart operation after restoration from output shutoff by the MRS (X10) signal is as shown in the following table
according to the Pr.30 setting.

Other than the above Starting from Pr.13 Starting frequency.

NOTE
• When output is shut off using safety stop function (terminals S1 and S2), the inverter restarts in the same way as when output
is shut off by the MRS (X10) signal.
• Operation is selectable as shown in the table above when Pr.162 Automatic restart after instantaneous power failure
selection = "0 or 1". When Pr.162 Automatic restart after instantaneous power failure selection = "10 or 11" (automatic
restart operation at each start), a restart operation is performed regardless of the setting of Pr.30 Regenerative function
selection.
• Set "24" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the output stop (MRS) signal
to the input terminal, and "10" to assign the Inverter operation enable (X10) signal.

  Adjustment of restart coasting time (Pr.57)
• Restart coasting time is the time period from the occurrence of instantaneous power failure until the operation is restarted
after power is restored.
With frequency search, the motor speed is detected and operation is restarted after the coasting time.
• To enable restart operation, set "0" to Pr.57 Restart coasting time. If "0" is set to Pr.57, the coasting time is automatically
set to the following number of seconds. Generally, this setting does not interfere with inverter operation.

 Restart cushion time (Pr.58)

• The cushion time is the time taken to raise the voltage to the level required for the specified speed after the motor speed
detection (output frequency before the instantaneous power failure when Pr.162 = "1 or 11").
• Normally, the motor runs at the initial value as it is. However, adjust to suit the moment of inertia (J) of the load or the size
of the torque.

NOTE
• Pr.58 is invalid under Real sensorless vector control or Vector control.

• The stall prevention operation level at a restart operation can be set in Pr.165.
11
• Using Pr.611, the acceleration time to reach Pr.20 Acceleration/deceleration reference frequency after a restart
operation can be set. This can be set individually from the normal acceleration time.
12
NOTE
• Pr.165 is invalid under Real sensorless vector control or Vector control.
• Changing the Pr.21 setting does not affect the Pr.611 setting increment.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.

Set parameters after confirming the function of each terminal.
• The SU and FU signals are not output during the restart. These signals are output after the restart cushion time passes.

CAUTION 15
• When the automatic restart after instantaneous power failure function is selected, the motor suddenly starts (after reset
time passes) when an instantaneous power failure occurs. Stay away from the motor and machinery.
When the automatic restart after instantaneous power failure function has been selected, apply the CAUTION sticker(s), 16
which are found in the Inverter Safety Guideline enclosed with the inverter, to easily visible places.

smoothly.
• The encoder also detects the rotation direction so that the inverter can re-start smoothly even during the reverse rotation.
• When "10 (or 11)" is set in Pr.162, a restart operation is performed at each start and automatic restart after instantaneous
power failure. When "0 (or 1)" is set in Pr.162, a restart operation is performed at the first start after a power-ON, and from
the second power-ON onwards, a start from the starting frequency is performed.

• Restart operation with reduced voltage is not available for PM sensorless vector control.
• A protective function may be activated for some motor models or at certain running speeds, disabling restarting.

 Restart coasting time (Pr.57)

• Coasting time is the time from the motor speed detection to the restart operation start.
• To enable restart operation, set "0" (no coasting time) in Pr.57 Restart coasting time. Generally, this setting does not
interfere with inverter operation.

508 15. (A) Application Parameters

15.10 Automatic restart after instantaneous power failure / flying start with a PM motor
 • Inverter operation is sometimes hindered by the size of the moment of inertia (J) of the load or the output frequency. Adjust
this coasting time within the range 0.1 to 30 seconds to match the load specification.
11
 Adjustment of restart operation (Pr.611)
• Pr.611 can be used to set the acceleration time after a restart operation for the speed to reach Pr.20 Acceleration/
deceleration reference frequency. This time can be set individually from the normal acceleration time. 12
NOTE
• Changing the Pr.21 Acceleration/deceleration time increments setting does not affect the Pr.611 setting increment.
• A PM motor is a motor with interior permanent magnets. Regression voltage is generated when the motor coasts at an
13
instantaneous power failure or at a flying start. The inverter's DC bus voltage rises if the motor coasts fast or makes a flying
start in this condition.
When using the automatic restart after instantaneous power failure function (Pr.57 ≠ "9999"), it is recommended to also use 14
the regenerative avoidance function (Pr.882 Regeneration avoidance operation selection = "1") to make startups stable. If
the overvoltage protective function (E.OV[]) still occurs with the regeneration avoidance function, also use the retry function
(Pr.67).
• When a built-in brake or a regeneration unit is used, the frequency search may not be available while the motor speed is equal 15
to or higher than the motor rated speed plus 10%. The restart operation cannot be performed until the motor speed drops to
a frequency where the frequency search is available.
16

CAUTION
• A PM motor is a motor with interior permanent magnets. High voltage is generated at motor terminals while the motor is 17
running.
Do not touch motor terminals and other parts until the motor stops to prevent an electric shock.
• When the automatic restart after instantaneous power failure function is selected, the motor suddenly starts (after reset 18
time passes) when an instantaneous power failure occurs.
Stay away from the motor and machinery.
When the automatic restart after instantaneous power failure function has been selected, apply the CAUTION sticker(s), 19
which are found in the Inverter Safety Guideline enclosed with the inverter, to easily visible places.

 Offline auto tuning for a frequency search

• When the frequency search is selected by setting Pr.162 Automatic restart after instantaneous power failure selection
= "0 or 10", perform offline auto tuning.

 Before performing offline auto tuning

Check the following points before performing offline auto tuning:
• V/F control is selected.
• Check that a motor is connected. (Check that the motor is not rotated by an external force during tuning.)
• The rated motor current should be equal to or less than the inverter rated current.
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque
accuracies may deteriorate due to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter
rated current. (For details on the inverter rated current, refer to the inverter rated specifications in the Instruction Manual
(Connection).)
• The target motor is other than a high-slip motor, a high-speed motor, or a special motor.
• The motor may rotate slightly even if the offline auto tuning without the motor rotating (Pr.96 Auto tuning setting/status
= "11") is selected. Fix the motor securely with a mechanical brake, or before tuning, make sure that it is safe even if the
motor rotates. (Caution is required especially in vertical lift applications.) Note that even if the motor runs slightly, tuning
performance is unaffected.

15.11 Offline auto tuning for a frequency search
 • Offline auto tuning is not performed correctly when the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) is inserted
between the inverter and motor. Be sure to remove them before performing tuning.

 Performing tuning
18
• Before performing tuning, check the monitor display of the operation panel or parameter unit if the inverter is in the state ready
for tuning. The motor starts by turning ON the start command while tuning is unavailable.

19
• In the PU operation mode, press the RUN key on the operation panel or the FWD/REV key on the parameter unit.
In the External operation, turn ON the start command (STF signal or STR signal). Tuning starts. (At this time, excitation
noise occurs.)
20
NOTE
• It takes about 10 seconds for tuning to complete. (The time depends on the inverter capacity and motor type.)
• Satisfy the required inverter start conditions to start offline auto tuning. For example, stop the input of the MRS signal.
• To force tuning to end, use the MRS or RES signal or the STOP/RESET key on the PU.
(Turning OFF the start signal (STF signal or STR signal) also ends tuning.)
• During offline auto tuning, only the following I/O signals are valid (initial value).
Input terminals <effective signals>: MRS, RES, STF, STR, S1, and S2
Output terminals: RUN, FM, AM, ABC, and SO
• When the rotation speed and the output frequency are selected for terminals FM and AM, the progress status of offline auto
tuning is output in 15 steps from FM and AM.
• Do not perform ON/OFF switching of the Second function selection (RT) signal during offline auto tuning. Auto tuning will not
be performed properly.
• Since the RUN signal turns ON when tuning is started, pay close attention especially when a sequence which releases a
mechanical brake by the RUN signal has been designed.
• When executing offline auto tuning, input the operation command after switching ON the main circuit power (R/L1, S/L2, T/L3)
of the inverter.
• While Pr.79 Operation mode selection = "7", turn ON the PU operation external interlock (X12) signal for tuning in the PU
operation mode.

• When offline auto tuning ends, press the STOP/RESET key on the PU during PU operation. For External operation, turn
OFF the start signal (STF signal or STR signal). This operation resets the offline auto tuning, and the monitor display of
the operation panel returns to normal. (Without this operation, next operation cannot be started.)
• At tuning completion, the tuning results are set in the following parameters:

NOTE
• The motor constants measured once during offline auto tuning are stored as parameters and their data are held until offline
auto tuning is performed again. However, the tuning data is cleared when performing All parameter clear.

• If offline auto tuning has ended in error, motor constants are not set.
Perform an inverter reset and perform tuning again.

92 The converter output voltage fell to 75% of the rated voltage. Check for the power supply voltage fluctuation.
Calculation error.
93 Check the motor wiring and make the setting again.
The motor is not connected.
• When tuning is ended forcibly by pressing the STOP/RESET key or turning OFF the start signal (STF or STR) during
tuning, offline tuning does not end properly. (The motor constants have not been set.)
Perform an inverter reset and perform tuning again.
• When the rated power supply of the motor is 200/220 V (400/440 V) 60 Hz, set the rated motor current multiplied by 1.1 in
Pr.9 Electronic thermal O/L relay after tuning is complete.
• For a motor with a PTC thermistor, thermal protector, or other thermal detection, set "0" (motor overheat protection by
inverter invalid) in Pr.9 to protect the motor from overheating.

NOTE
• An instantaneous power failure occurring during tuning will result in a tuning error. After power is restored, the inverter starts
normal operation. Therefore, when the STF (STR) signal is ON, the motor starts forward (reverse) rotation.
• Any fault occurring during tuning is handled as in the normal operation. However, if the retry function is set, no retry is
performed.
• The set frequency monitor displayed during the offline auto tuning is 0 Hz.

• When one inverter switches the operation between two different motors, set the second motor in Pr.450 Second applied 11
motor, set Pr.463 Second motor auto tuning setting/status = "11", and perform tuning of the second motor.
• Turning ON the RT signal enables the parameter settings for the second motor as shown in the following table.

(E.ILF) occurs.) 17
• The Y46 signal is turned ON during deceleration at occurrence of power failure and in a stop status after deceleration at
occurrence of power failure.
• For the Y46 signal, set "46" (positive logic) or "146" (negative logic) in any parameter from Pr.190 to Pr.197 (Output 18

NOTE
• The power failure time deceleration stop function is disabled during a stop or when the breaker is tripped.
19
• Changing the terminal assignment using Pr.190 to Pr.197 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

sequence program. The result of performing calculation by a sequence
A859
program can also be monitored by Pr.1150 to Pr.1199.

 Outline of PLC function

• To enable the PLC function, set a value other than "0" in Pr.414 PLC function operation selection. (The Pr.414 setting
change becomes valid after inverter reset.)
• Switch the execution key (RUN/STOP) of the sequence program by turning the SQ signal ON/OFF. The sequence program
can be executed by turning the SQ signal ON. To input the SQ signal, set "50" in any parameter from Pr.178 to Pr.189
(Input terminal function selection) to assign the function to a terminal.
• When "1" is set in Pr.415 Inverter operation lock mode setting, the inverter can be operated only when the sequence
program is running. By changing the PLC program status from RUN to STOP during inverter operation, the motor
decelerates to stop. To stop the inverter operation at the STOP status of the PLC program while performing auto operation
using SD1148 (or SM1200 to 1211) of the PLC program, set Pr.415 = "1".
• For reading or writing sequence programs, use FR Configurator2 on the personal computer connected to the inverter via
RS-485 communication or USB. (When Pr.414 ≠ "0", sequence programs can be read from or written to FR Configurator2.)

 Sequence start (SQ) signal

• Switch the execution key (RUN/STOP) of the sequence program by turning the SQ signal ON/OFF. The sequence program
can be executed by turning the SQ signal ON. To input the SQ signal, set "50" in any parameter from Pr.178 to Pr.189
(Input terminal function selection) to assign the function. When the SQ signal is assigned to any parameter from Pr.185
to Pr.189 (Terminal NET X function selection), the sequence program can be executed just by inputting the SQ signal
via terminal NET X. (The SQ signal needs not be input via an external terminal.)
• When Pr.414 = "1 or 11", the SQ signal must be input according to the command source (except when the SQ signal is
assigned to terminal NET X).

516 15. (A) Application Parameters

15.13 PLC function

 User parameter (data register (D)) auto storage function selection
• Setting Pr.675 = "1" enables the auto storage function for user parameters. 14
• The user parameter auto storage function is used to store the setting of Pr.1195 PLC function user parameters 46 (D251)
to Pr.1199 PLC function user parameters 50 (D255) automatically in EEPROM at power OFF or inverter reset.

NOTE 15
• The auto storage function may fail if the EEPROM is accessed by other functions at the same time at power OFF.

 User parameter reading from EEPROM 16

• User parameters (Pr.1150 to Pr.1199) are read from RAM or EEPROM according to the settings in Pr.342
Communication EEPROM write selection and Pr.414 PLC function operation selection. When Pr.414 = "11 or 12",

 Operation outline
• This function is used to sample the status data (analog monitor and digital monitor) of the inverter, trace the sampling data
17
when a trigger (trace start condition) occurs, and stores the resulting trace data.
• When the trace function is set enabled, samplings are collected and the inverter goes into the pre-trigger status.
• In the pre-trigger status, samples are collected, and the trigger standby status is entered when sufficient samples for the
18
number of pre-trigger samples have been collected.
• When a trigger occurs in the trigger standby status, tracing is started and the trace data is stored.

16.1 Manual torque boost

V/F

Voltage drop in the low-frequency range can be compensated, improving reduction of the motor torque in the low-speed range.
• Motor torque in the low-frequency range can be adjusted according to the load, increasing the motor torque at the start up.
• By using the RT signal, it is possible to switch between 2 types of torque boost.

 Starting torque adjustment
• Assuming Pr.19 Base frequency voltage is 100%, set the output voltage at 0 Hz to Pr.0 (Pr.46) in percentage.
• Perform the adjustment of the parameter little by little (approximately 0.5%), and confirm the status of the motor each time. 18
The motor may overheat when the value is set too high. Do not use more than 10% as a guideline.

 Setting multiple torque boosts (RT signal, Pr.46)

• When changing the torque boost depending on the application or when using single inverter switching between multiple
motors, use the second torque boost.
• Pr.46 Second torque boost is enabled when the RT signal is ON. To input the RT signal, set "3" in any parameter from
Pr.178 to Pr.189 (Input terminal function selection) to assign the function.

NOTE
• The RT signal is the Second function selection signal which also enables other second functions. (Refer to page 418.)
• Set a larger value when the distance between the inverter and the motor is long or when there is not enough motor torque in
the low-speed range. It may cause overcurrent trip when it is set too large.
• Setting for Pr.0 and Pr.46 becomes enabled only when the V/F control is selected.
• When the initial value is set in Pr.0, the Pr.0 setting is automatically changed by changing the Pr.71 Applied motor or Pr.81
Number of motor poles setting. (Refer to page 424.)
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

*1 Gr.1 and Gr.2 are the parameter initial value groups. (Refer to page 54).

 Base frequency setting (Pr.3)

• When operating a standard motor, generally set the rated frequency of the motor in Pr.3 Base frequency. When the motor
operation require switching to the commercial power supply, set the power supply frequency in Pr.3.
• When the frequency described on the motor rating plate is "50 Hz" only, make sure to set to 50 Hz. When it is set to 60 Hz,
the voltage will drop too much, causing insufficient torque. As a result, the inverter output may be shut off due to overload.
A caution is required especially in case of Pr.14 Load pattern selection = "1" (variable torque load).
• When using the Mitsubishi Electric constant torque motor, set Pr.3 to 60 Hz.

 Setting multiple base frequencies (Pr.47)

• To change the base frequency when using a single inverter switching between multiple motors, use Pr.47 Second V/F
(base frequency).
• Pr.47 is enabled when the RT signal is ON. To input the RT signal, set "3" in any parameter from Pr.178 to Pr.189 (Input
terminal function selection) to assign the function.

NOTE
• The RT signal is the Second function selection signal which also enables other second functions. (Refer to page 418.)

 Setting of base frequency voltage (Pr.19)

• Use Pr.19 Base frequency voltage to set the base voltage (for example, rated motor voltage).
• When it is set lower than the power supply voltage (approximately twice of the power supply voltage for a single-phase 100
V power input model), maximum output voltage of the inverter will be the voltage set in Pr.19.

530 16. (G) Control Parameters

16.2 Base frequency voltage
 • Pr.19 can be used in the following cases.
(a) When regenerative driving (continuous regeneration, etc.) is performed frequently
Output voltage will get higher than the specification during the regenerative driving, which may cause overcurrent trip
11
(E.OC[]) by the increase in motor current.
(b) When the fluctuation of power supply voltage is high
When the power supply voltage exceeds the rated voltage of the motor, fluctuation of rotation speed or overheating 12
of motor may occur due to excessive torque or increase in motor current.
• To operate a Vector control dedicated motor (SF-V5RU) with V/F control, the setting is as shown in the following table.
13

SF-V5RUH, 3.7 kW or lower 340 V
SF-V5RUH, 5.5 kW or higher 320 V

NOTE 15
• When the operation becomes not possible due to failure in encoder or other reasons under Vector control, set "9999" in Pr.80
Motor capacity or Pr.81 Number of motor poles to perform V/F control.
• When the Advanced magnetic flux vector control, Real sensorless vector control, Vector control, or PM sensorless vector 16
control is selected, Pr.3, Pr.47, and Pr.19 will become disabled, and Pr.83 and Pr.84 will become enabled.
However, S-pattern curve with Pr.29 Acceleration/deceleration pattern selection = "1" (S-pattern acceleration/deceleration
A) enables Pr.3 or Pr.47. (S-pattern curve under PM sensorless vector control is the rated frequency of the motor.)
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions. 17
Set parameters after confirming the function of each terminal.

G030 control selection 9 Optimum excitation control

 Optimum excitation control (Pr.60 = "9")

• Setting Pr.60 = "9" will select the Optimum excitation control.
• The Optimum excitation control is a control method to decide the output voltage by controlling the excitation current so the
efficiency of the motor is maximized.
• Optimum excitation control will be enabled under V/F control and Advanced magnetic flux vector control.

NOTE
• In the Optimum excitation control mode, an energy saving effect is not expected when the motor capacity is extremely small
compared with the inverter capacity or when multiple motors are connected to a single inverter.
• When the Optimum excitation control mode is selected, the deceleration time may become longer than the setting value. Also,
it may cause overvoltage more often compared to constant-torque load characteristics, so set the deceleration time longer.
• When the motor becomes unstable during the acceleration, set the acceleration time longer.
• Output current may increase slightly with the energy saving operation mode or the Optimum excitation control mode since the
output voltage is controlled.

16.5 SF-PR slip amount adjustment mode 11

V/F

• As compared to our conventional SF-JR motor, the slip amount is small for the high-performance energy-saving SF-PR
12
motor. When replacing the SF-JR to the SF-PR, the slip amount is reduced and the rotations per minute increases.
Therefore, when the SF-PR is used with the same frequency setting as that of the SF-JR, power consumption may
increase as compared to the SF-JR.
13
• By setting the slip amount adjustment mode, the frequency command can be adjusted to keep the rotations per minute of
the SF-PR equivalent to those of the SF-JR for power consumption reduction.

• The SF-PR slip amount adjustment mode is available only under V/F control.
• Use Pr.674 SF-PR slip amount adjustment gain to fine-tune the rotations per minute. To reduce the rotations per minute 17
(to increase the compensation frequency), set a larger value in Pr.674. To increase the rotations per minute (to reduce the
compensation frequency), set a smaller value in Pr.674. (Lower rotations per minute reduce the power consumption, and
higher rotations per minute increase the power consumption.) 18

• The slip amount adjustment is not available in the following conditions.
During acceleration/deceleration, during DC injection brake operation, during PID control, during orientation control, during

encoder feedback control, during stall prevention operation, during regeneration avoidance operation, during traverse
operation, and while the slip compensation is valid (Pr.245).

• Adjust the braking torque and timing to stop the motor using the DC injection brake.
Zero speed control is also available under Real sensorless vector control, and zero speed control and servo lock are
selectable under Vector control or PM sensorless vector control.
When the DC injection brake operation is used, DC voltage is applied to the motor to prevent rotation of the motor shaft,
and when the zero speed control is used, Vector control is performed to keep 0 r/min. Either way, when a motor shaft is
rotated by external force, it does not go back to the original position.
When the servo lock control is used, the position of the motor shaft is held. When a motor shaft is rotated by external force,
it goes back to the original position.
• Select the magnetic flux decay output shutoff function to decay the magnetic flux before shutting off the output at a stop.

 Setting of operating frequency (Pr.10)

• By setting the frequency for DC injection brake operation (zero speed control / servo lock) to Pr.10 DC injection brake
operation frequency, DC injection brake operation (zero speed control / servo lock) starts when the frequency reaches
the Pr.10 setting during deceleration.

NOTE
• When executing pre-excitation (zero speed control) under Real sensorless vector control, set Pr.10 DC injection brake
operation frequency to 0.5 Hz or lower since it may cause motor vibration, etc., at the time of deceleration stop.
• The initial value of Pr.10 will automatically switch to 0.5 Hz under Vector control.

 Operation time setting (X13 signal, Pr.11)

• Set the operation time for DC injection brake (zero speed control / servo lock) in Pr.11 DC injection brake operation time.
• When the motor does not stop due to large load moment (J), increase the setting to ensure the effect.
• When Pr.11 = "0 s", DC injection brake (zero speed control / servo lock) does not start. (The motor starts to coast when
the output frequency drops to the Pr.10 setting or lower at a stop.)
• When Pr.11 = "8888", DC injection brake (zero speed control / servo lock) starts when the X13 signal is turned ON. DC
injection brake (zero speed control / servo lock) will start when the X13 signal is turned ON, even during operation, during
automatic restart after instantaneous power failure, or during offline auto tuning.

NOTE
• Under Real sensorless vector control, when the X13 signal turns ON while Pr.11 = "8888", the zero speed control is activated
regardless of the Pr.850 Brake operation selection setting.
• Under Vector control, zero speed control or servo lock starts depending on the setting of Pr.802.
• When the X13 signal is turned ON while online auto tuning is performed at startup, DC injection brake (zero speed control /
servo lock) will start after the tuning is completed.

 Setting of operation voltage (torque) (Pr.12)

• Set the percentage against the power supply voltage in Pr.12 DC injection brake operation voltage. (The setting is not
used for zero speed control or servo lock.)
• The DC injection brake operation is not available when the setting of Pr.12 is 0%. (The motor starts to coast when the
output frequency drops to the Pr.10 setting or lower at a stop.)
• The Pr.12 setting is disabled under PM sensorless vector control.

NOTE
• When the setting of Pr.12 is the initial value, the setting corresponding to the motor is set according to the Pr.71 Applied motor
setting. (Refer to page 428.) However, when an energy saving motor (SF-HR or SF-HRCA) is used, change the Pr.12 setting
as shown below.

Motor capacity Pr.12 setting

3.7 kW or lower 4%
5.5 kW, 7.5 kW 3%
11 kW or higher 2%

• Even if the setting value of Pr.12 is made larger, braking torque will be limited so the output current will be within the rated
current of the inverter.

 Braking operation selection under Real sensorless vector control (Pr.850

= "0 or 1")
• The braking operation under Real sensorless vector control can be selected between the DC injection brake operation
(initial setting) and zero speed control.
By setting Pr.850 Brake operation selection = "1", zero speed control will be performed at the frequency set in Pr.10 DC
injection brake operation frequency or lower.

NOTE
• Under Real sensorless vector control, when the X13 signal turns ON while Pr.11 = "8888", the zero speed control is activated
regardless of the Pr.850 setting.
• When restarting the operation after a brake operation under Real sensorless vector control, set Pr.850 = "1" (zero speed
control). Setting "0" (DC injection brake) may cause a delay of about 2 seconds from the time the start up command is input
until it actually is output.

538 16. (G) Control Parameters

16.6 DC injection brake, zero speed control, servo lock, and magnetic flux decay output shutoff
 Magnetic flux decay output shutoff and the Magnetic flux decay output
shutoff signal (X74 signal, Pr.850 = "2") 11
• Frequent starts/stops (inching) under Real sensorless vector control may cause an inverter failure or create a difference
in operation with the motor. The reason is that some magnetic flux is left in the motor at shutoff of the inverter output. If this
is the case, set Pr.850 = "2" (magnetic flux decay output shutoff) or turn ON the Magnetic flux decay output shutoff (X74) 12
signal to decay the magnetic flux at a stop, and then shut off the output.
• While Pr.850 = "2", deceleration starts at turning OFF of the start command, and the magnetic flux decay output shutoff is
activated when the estimated speed becomes lower than Pr.10 DC injection brake operation frequency. 13
• While the brake sequence function is active, the magnetic flux decay output shutoff is activated when the running frequency
drops to 0.5 Hz or Pr.13 Starting frequency, whichever is smaller.
• Inverter output voltage shutoff timing when Pr.850 = "2" 14

 • The magnetic flux decay output shutoff will be canceled at the time of restart and when the Pre-excitation/servo ON (LX)
signal or External DC injection brake operation start (X13) signal is turned ON.
• If an MC is installed at the inverter's output side, set to open the MC after the operation time of the magnetic flux decay
output shutoff elapses. (See below.)
Motor capacity (Pr.80 setting) 2.2 kW or lower 3.7 kW to 11 kW 15 kW to 30 kW
Magnetic flux decay process time 250 ms 500 ms 800 ms

NOTE
• Under a control other than Real sensorless vector control, the inverter will immediately shutoff the output when the X74 signal
is turned ON.
• Even under Real sensorless vector control, the inverter will immediately shutoff the output when the X74 signal is turned ON
during the automatic restart after instantaneous power failure and online auto tuning during the start up.
• If another output-shutoff trigger (inverter fault, turning ON the MRS signal, etc.) occurs during the magnetic flux decay
operation, the magnetic flux decay operation is terminated, and the output is shut off immediately.
• Unlike the MRS signal, voltage is output during the magnetic flux decay output shutoff operation, so take caution on electric
shocks.
• When the release timing of the mechanical brake is too fast, the motor shaft may be rotated by dropping or external force.
When the release timing is too late, the overcurrent prevention operation, stall prevention operation, or electronic thermal O/
L relay function may be activated. Perform release of the mechanical brake matching the equipment using the Output
frequency detection (FU) signal or Output current detection (Y12) signal.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

 Brake operation selection under Vector control (Pr.802, Pr.1299)

speed control or servo lock.

NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
• Performing pre-excitation (LX signal and X13 signal) under torque control may start the motor running at a low speed even
when the start signal (STF or STR) is not input. This product with the start command ON may also rotate the motor at a low
speed when the speed limit value is set to zero. Confirm that the motor running does not cause any safety problems before
performing pre-excitation.
• Note that during the pre-excitation operation, a voltage is applied to the motor even when the [RUN] LED on the operation
panel or the FWD/REV indicator on the parameter unit is OFF.
• When offline auto tuning (Pr.96 Auto tuning setting/status = "1, 11, or 301") is performed during pre-excitation operation,
pre-excitation is disabled.
• When the LX signal is ON and the start signal is OFF at the automatic restart after instantaneous power failure, the motor does
not decelerates to stop from the detected motor speed, and pre-excitation (zero speed control / servo lock) is applied.

output is shut off by turning OFF the start signal.
• When the restart signal is turned ON during the motor coasting, the operation is resumed from Pr.13 Starting frequency.
• Even with the setting of coasting to a stop, when the LX signal is turned ON, the motor does not coast but zero speed control

• When performing frequent start and stop operation, usage rate of the regenerative brake can be increased by using the
optional high-duty brake resistor (FR-ABR) or the brake unit (FR-BU2, BU, or FR-BU). 12
• The multifunction regeneration converter (FR-XC in power regeneration mode) or power regeneration common converter
(FR-CV) is used for the continuous operation in the regenerative status. The multifunction regeneration converter (FR-XC
in common bus regeneration mode) and high power factor converter (FR-HC2) can also be used to reduce harmonics, 13
improve power factor, and operate continuously during regenerative driving. The multifunction regeneration converter (FR-
XC), power regeneration common converter (FR-CV), and high power factor converter (FR-HC2) cannot be used with the
safety communication model and the IP67 model. 14
• When the FR-E8DS is installed, the reset operation when the power is supplied to the main circuit while 24 V external

• When using the FR-XC or FR-HC2, enable the automatic restart after instantaneous power failure function in both the FR- 15
XC/FR-HC2 and the inverter (Pr.57 Restart coasting time ≠ "9999").
• If the FR-XC or FR-HC2 detects the power failure during inverter running, the motor starts to coast since the Inverter
operation enable (RYB or RDY) signal turns ON. After the power is restored and the Inverter operation enable (RYB or 16
RDY) signal turns OFF, the inverter detects the motor speed (Pr.162 Automatic restart after instantaneous power
failure selection) and restarts operation.

 Logic reversing of the Inverter run enable signal (X10 signal, Pr.17) 17
• Use Pr.17 MRS/X10 terminal input selection to select the X10 signal input specification between normally open (NO
contact) and normally closed (NC contact). With the normally closed (NC contact) input specification, the inverter output is
shut off by turning OFF (opening) the X10 signal.
18
• Change the Pr.17 setting to change the inverter logic (NO/NC contact) according to the logic of the inverter operation
enable signal sent from the converter unit.
• The logic of the MRS signal can also be selected by setting Pr.17. Refer to page 416 to select the logic of the MRS signal.

 NOTE
• When Pr.30 = "0, 2, 100, or 102" and the X10 signal is not assigned to an input terminal, the MRS signal can be used as the
X10 signal. The logic of the signal depends on that of the MRS signal (normally open input when Pr.17 = "0 or 1", and normally
closed input when Pr.17 = "2 to 5").
• The MRS signal is valid regardless of whether it is input through the external terminal or via network (except for the FR-E800-
SCE), but when the MRS signal is used as the Inverter run enable (X10) signal, input the signal through the external terminal.
• When the terminal assignment is changed with Pr.178 to Pr.184 (Input terminal function selection), wiring may be mistaken
due to different terminal name and signal contents, or may affect other functions. Set parameters after confirming the function
of each terminal.

 Regenerative brake duty warning output and the warning signal (RBP
signal)
• When the regenerative brake duty reaches 85% of the Pr.70 setting, "RB" is indicated on the operation panel and the
Regenerative brake prealarm (RBP) signal is output. When it reaches 100% of the Pr.70 setting, it will become
regenerative overvoltage (E.OV[]).
• The inverter output is not shut off with the warning signal.
• For the RBP signal output, set "7" (positive logic) or "107" (negative logic) to any parameter from Pr.190 to Pr.197 (Output
terminal function selection) to assign the function.

 Connection of a brake resistor other than the FR-ABR, MRS type, and

A brake resistor can be used with the FR-E820-0030(0.4K) or higher, FR-E840-0016(0.4K) or higher, FR-E860-0017(0.75K)

 • When the regenerative brake transistor is damaged, install a thermal relay to prevent overheat and burnout of the brake
resistor. (Refer to the Instruction Manual (Connection) to install a thermal relay.) Properly select a thermal relay according
to the regenerative driving frequency or the rated power or resistance of the brake resistor.

CAUTION
• If the resistor selection is incorrect, overcurrent may damage the inverter built-in brake transistor. Besides, the resistor
may be burned due to overheat.
• If the selection of the thermal relay is incorrect, the resistor may be burned due to overheat.

 Selection between resetting or not resetting during power supply to main

circuit (Pr.30 = "100 to 102") (standard model, Ethernet model)
• When Pr.30 = "100" or higher value and the FR-E8DS is installed, the inverter will not be reset when power is supplied to
the main circuit (via terminals R/L1, S/L2, and T/L3) while 24 V power is supplied to the inverter.
• When the RS-485 communication or Ethernet communication is used, communication interruption due to the inverter reset
can be avoided.

NOTE
• When supplying power to the main circuit is started while the protective function of the inverter is activated, inverter reset is
performed at power-ON even when "no reset" is selected.
• When the emergency drive function is enabled and "no reset" is selected, the inverter may start immediately after supplying
power to the main circuit.
• When "no reset" is selected, STW1 for PROFINET or the controlword for EtherCAT is retained. Check status transition
commands before supplying power to the main circuit. (Refer to the Instruction Manual (Communication).)
• For the safety communication model and the IP67 model, the setting is fixed to "reset".

 Regeneration avoidance operation (Pr.882, Pr.883) 19

• When the regenerative voltage increases, the DC bus voltage will rise, which may cause an overvoltage fault (E.OV[]). The
regenerative status can be avoided by detecting this rise of bus voltage, and raising the frequency when the bus voltage
level reaches or exceeds Pr.883 Regeneration avoidance operation level.

 NOTE
• The slope of frequency rising or lowering by the regeneration avoidance operation will change depending on the regenerative
status.

• The DC bus voltage of the inverter will be approximately √2 times of the normal input voltage (twice of the input voltage for
the 100 V class).
The bus voltage is approx. 311 VDC at an input voltage of 220 VAC (283 VDC at 100 VAC, 622 VDC at 440 VAC, and 813
VDC at 575 VAC). However, it may vary depending on the input power supply waveform.
• Make sure that the setting value of Pr.883 will not get under DC bus voltage level. The frequency will rise with operation of the
regeneration avoidance function even during operation other than the regenerative operation.
• The stall prevention (overvoltage) (OLV) will be activated only during deceleration, stopping the lowering of output frequency.
On the other hand, the regeneration avoidance function will be activated constantly (Pr.882 = "1") or only at constant speed
(Pr.882 = "2"), and raise the frequency depending on the amount of regeneration.
• When the motor becomes unstable due to the stall prevention (overcurrent) (OLC) during the regeneration avoidance
operation, increase the deceleration time or set a lower value in Pr.883.

 Limiting the regeneration avoidance operation frequency (Pr.885)

• It is possible to assign a limit to the output frequency corrected (rise) by the regeneration avoidance operation.
• Limit of the frequency is output frequency (frequency before regeneration avoidance operation) + Pr.885 Regeneration
avoidance compensation frequency limit value for during acceleration and constant speed. During deceleration, when
the frequency increases due to the regeneration avoidance operation and reaches the limit value, the limit value will be
retained until the output frequency is reduced to be the half the Pr.885 setting.
• The regeneration avoidance operation frequency is limited at the setting of Pr.1 Maximum frequency.
• When Pr.885 = "9999", the regeneration avoidance compensation frequency limit is disabled.
• Set the frequency around the motor rated slip frequency. Increase the setting value if the overvoltage protection function
(E.OV[]) is activated at the start of deceleration.

 Adjusting the regeneration avoidance operation (Pr.665, Pr.886)

• If the frequency becomes unstable during regeneration avoidance operation, decrease the setting of Pr.886 Regeneration
avoidance voltage gain. On the other hand, if an overvoltage fault occurs due to a sudden regeneration, increase the
setting.
• If setting a smaller value in Pr.886 does not suppress the vibration, set a smaller value in Pr.665 Regeneration avoidance
frequency gain.

16.9 Regeneration avoidance function
 NOTE
• During the regeneration avoidance operation, the stall prevention (overvoltage) "OLV" is displayed and the Overload warning 11
(OL) signal is output. Set the operation pattern at an OL signal output using Pr.156 Stall prevention operation selection.
Use Pr.157 OL signal output timer to set the OL signal output timing.
• The stall prevention is enabled even during regeneration avoidance operation.
• The regeneration avoidance function cannot decrease the actual deceleration time for the motor to stop. Since the actual
12
deceleration time is determined by the regenerative power consumption performance, consider using a regeneration unit (FR-
BU2, BU, FR-BU, FR-XC, FR-CV, FR-HC2) or brake resistor (FR-ABR, etc.) to decrease the deceleration time.
• When using a regeneration unit (FR-BU2, BU, FR-BU, FR-XC, FR-CV, FR-HC2) or brake resistor (FR-ABR, etc.) to consume 13
the regenerative power at constant speed, set Pr.882 = "0 (initial value)" (the regeneration avoidance function is disabled).
When consuming the regenerative power at the time of deceleration with the regeneration unit, etc., set Pr.882 = "2" (enables
regeneration avoidance function only at the constant speed).
• When using the regeneration avoidance function under Vector control, noise may be generated from the motor during 14
deceleration. In such case, adjust the gain. (Refer to page 146.)

• Speed loop response is reduced. Under ordinary circumstances, therefore, use the initial value as it is. 16
If there is speed ripple due to high frequency disturbance, gradually raise the setting value until speed stabilizes. Speed is
oppositely destabilized if the setting value is too large.
• This setting is valid under Vector control only. 17
 Employing multiple primary delay filters
• Use Pr.833 if changing filter according to application. Pr.833 is enabled when the Second function selection (RT) signal is
turned ON.
18
NOTE
• The RT signal is the Second function selection signal. The RT signal also enables other second functions. (Refer to page 418.) 19
• The RT signal is assigned to terminal RT in the initial status. Set "3" in one of Pr.178 to Pr.189 (Input terminal function

 Setting before operation (Pr.359, Pr.369)

• Use Pr.359 Encoder rotation direction and Pr.369 Number of encoder pulses to set the rotation direction and the
number of pulses for the encoder.

NOTE
• Control with correct speed is not possible if the number of poles for the applied motor is incorrect. Check first before operation.
Operating the inverter with Pr.81 = "10 or 12" causes "SE" (incorrect parameter setting) alarm.
• Encoder feedback control is not possible when the rotation direction setting of the encoder is incorrect. (Operation of the
inverter is possible.)
Check the indicator on the parameter unit to confirm the direction.

  Selection of encoder feedback control (Pr.367)
• When a value other than "9999" is set in Pr.367 Speed feedback range, encoder feedback control is enabled. Set a target
value (frequency at which stable speed operation is performed) and specify the range around the value. Normally, use the
frequency converted from the slip amount (r/min) at the rated motor speed (rated load). If the setting is too large, response
becomes slow.

= 60 (r/min)
Frequency equivalent to slip (fsp) = Nsp × Number of poles/120
= 60 × 4/120
= 2 (Hz)

 Feedback gain (Pr.368)

• Set Pr.368 Feedback gain when the rotation is unstable or response is slow.
• Response of the feedback will become slow when the acceleration/deceleration time is long. In such case, increase the
setting value of Pr.368.
Pr.368 setting Description
Pr.368 > 1 Response will become faster but it may cause overcurrent or unstable operation.
1 > Pr.368 Response will become slower but the operation will become more stable.

 Overspeed detection (Pr.285)

• To prevent malfunction when the correct pulse signal cannot be detected from the encoder, when
[detection frequency] - [output frequency] > Pr.285
during encoder feedback control, a protective function (E.MB1) will be activated to shut off the inverter output.
• Overspeed detection is not performed when Pr.285 = "9999".

NOTE
• The encoder feedback control is disabled in the following conditions:
During offline auto tuning, when the PID control is enabled, during stop-on-contact control, during the current limit operation,
when the second function is enabled, and during orientation control
• Couple the encoder on the same axis as the motor axis without any mechanical clatter, with speed ratio of 1:1.
• Encoder feedback control is not performed during the acceleration and deceleration to prevent unstable operation such as
hunting.
• Encoder feedback control is performed after the output frequency has reached [set frequency] ± [speed feedback range] once.
• When the following status occurs during encoder feedback control operation, the inverter output is not shut off, the output
frequency becomes the value obtained by [set frequency] ± [speed feedback range], and tracking of the motor speed is not
performed.
When Pr.376 = "0" and the pulse signal from the encoder is lost due to a break or other reasons
When correct pulse signal cannot be detected due to induction noise or other reasons
When the motor is forcefully accelerated (regenerative rotation) or decelerated (motor lock) due to large external force
• Use the Inverter running (RUN) signal when releasing the brake from the motor with a brake under encoder feedback control.
(The brake may not be released when the Output frequency detection (FU) signal is used.)
• Do not turn OFF the external power supply for the encoder during encoder feedback control. Normal encoder feedback control
will not be possible.

 Setting method
• When vibration caused by mechanical resonance occurs, set 100% in Pr.653 Speed smoothing control, perform
operation at the frequency with the largest vibration, and check if the vibration is suppressed after few seconds.
• If the setting is not effective, gradually increase the value set in Pr.653 and repeat the operation to check the effect to
determine the most effective value (Pr.653).
• If the vibration increases by increasing the value in Pr.653, decrease the value in Pr.653 from 100% to check the effect.
• When the vibrational frequency at which mechanical resonance occurs (during fluctuation of torque, speed, or converter
output voltage) is measured using an instrument such as a tester, set 1/2 to 1 times of the vibrational frequency in Pr.654
Speed smoothing cutoff frequency. (Setting the resonance frequency range mitigates vibration more effectively.)

 • Installing the control terminal option FR-E8TR or FR-E8TE7 to the FR-E800 standard model can change the terminal block
type from the spring clamp type to the screw type. (Refer to the Instruction Manual of each option.)
• To use the PU connector, note that wiring methods are different. (Refer to the Instruction Manual (Connection).)

 Copying parameter settings

• The FR-E700 series' parameter settings can be easily copied to the FR-E800 series by using the setup software (FR
Configurator2). (Not supported by the setup software FR-SW3-SETUP or older.)

18.1.2 Replacement of the FR-E500 series

 Installation precautions
• Installation size is compatible. (Use the installation interchange attachment for replacement of the FR-E520-3.7K and FR-
E540-0.4K to 1.5K.)
• Operation panel (PA02) cannot be used.

Torque control Not available Real sensorless vector control or Vector control*2
*1 The rated motor current should be equal to or less than the inverter rated current. 17
If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque accuracies may deteriorate due
to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter rated current. (For details on the inverter rated current,
refer to the inverter rated specifications in the Instruction Manual (Connection).)
*2 A Vector control compatible option is required. Vector control is not available for the IP67 model as plug-in options are not available. 18
NOTE
• Before wiring, make sure that the motor is stopped. Otherwise you may get an electric shock.
• Never connect a PM motor to a commercial power supply. 19
• No slippage occurs with a PM motor because of its characteristic. If an IPM motor, which took over an induction motor, is driven
at the same speed as for the general-purpose motor, the running speed of the IPM motor becomes faster by the amount of
the general-purpose motor's slippage. Adjust the speed command to run the IPM motor at the same speed as the induction
motor, as required.
