Safety Precautions

Motor Selection

WARNING
Use only a Yaskawa permanent magnet motor in combination with this Inverter, specifically
SSE4-F21. Running any other permanent magnet motor with this Inverter may cause the
Inverter to operate abnormally. Consult with Yaskawa before attempting to use a motor other than
the model specified.

Confirmations upon Delivery

CAUTION
Never install an Inverter that is damaged or missing components.
Doing so can result in injury.

Installation

CAUTION
Always hold the case when carrying the Inverter.
If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.
Attach the Inverter to a metal or other noncombustible material.
Fire can result if the Inverter is attached to a combustible material.
Install a cooling fan or other cooling device when installing more than one Inverter in the same
enclosure so that the temperature of the air entering the Inverters is below 45C.
Overheating can result in fires or other accidents.

Wiring

WARNING
Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire can occur.
Wiring must be performed by an authorized person qualified in electrical work.
Otherwise, an electric shock or fire can occur.
Be sure to ground the ground terminal. (200 V Class: Ground to 100 or less, 400 V Class:
Ground to 10 or less)
Otherwise, an electric shock or fire can occur.
Always check the operation of any fast stop circuits after they are wired.
Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)
Never touch the output terminals directly with your hands or allow the output lines to come into con-
tact with the Inverter case. Never short the output circuits.
Otherwise, an electric shock or ground short can occur.
Do not use the Inverter for any load other than a three-phase AC motor.
A permanent magnet motor is a type of permanent magnet motor with a rotor in which a magnet is
integrated. Unlike an induction motor, the permanent magnet motor terminal generates high volt-
age when the motor is running, even when the Inverter power is shut off. Be sure to completely
stop the motor before wiring, maintenance and inspection.
Failure to do so may result in electric shock.

III
 WARNING
Wire the Inverter so that the Run command switches off when a Stop command (or Fast stop com-
mand) is input to terminal BB or terminal BB1.
If the Run command is not removed, then the motor will begin running as soon as the Stop com-
mand (or Fast stop command) is cleared.
This can result in personal injury.

CAUTION
Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the
Inverter.
Injury or fire can occur if the voltage is not correct.
Do not perform voltage withstand tests on the Inverter.
Otherwise, semiconductor elements and other devices can be damaged.
Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring
examples.
Otherwise, a fire can occur and the Inverter, braking resistors, Braking Resistor Units, and Braking Units can be damaged.
Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.
Do not connect AC power to output terminals U, V, and W.
The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.
The Inverter can be damaged or interior parts burnt if these devices are connected.
When a magnetic contactor is connected to the output circuits, do not switch it ON and OFF while
the Inverter is running.
Surge current will cause the overcurrent protection circuit inside the Inverter to operate.
This Inverter can drive an induction motor or a permanent magnet motor. Select a suitable control
method (parameter A1-02) for the motor you drive.
Failure to do so will cause damage to the motor.

Setting User Parameters

WARNING
Do not change the factory setting (0) in b1-03 (Run Command source selection).
Doing so can cause the elevator to drop.
Do not change the factory setting (1) in L8-05 (Input open-phase protection selection).
You can change it to 0, but only after confirming that there are no factors that cause input open
phase.
Doing so may damage the Inverter main circuits.

IV
 CAUTION
Disconnect the load (machine, device) from the motor before performing rotational autotuning or
pole tuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor parameters cannot be correctly set
with the motor attached to a load.
Stay clear of the motor until rotational autotuning or pole tuning has been successfully completed.
The motor could stop and then start again unexpectedly and this could result in injury.
Always confirm the following before rotational autotuning or pole tuning:
The lock key has been removed from the motor shaft.
There are neither people nor objects around the motor shaft.
The motor is at a complete stop.
Failure to do so may result in injury.
Be careful when handling the shaft and coupling.
Failure to do so may result in injury.
Be careful not to injure yourself with the key groove when turning the motor shaft by hand.
Failure to do so may result in injury.
When operating a permanent magnet motor for the first time, or after exchanging a permanent
magnet motor or an Inverter, set a correct motor parameter to the Inverter before the operation,
and be sure to check the motor speed detection.
Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as
directed, such as reverses, doesn't work, or over-accelerates.
Refer to Chapter 4 Trial Operation for details.
Do not change the parameter settings unnecessarily.
Doing so may impede motor operation.
When running a permanent magnet motor, be sure to set the following parameters.
Motor related parameters (E1-, E5-)
Parameters for PG open-circuit detection function (F1-)
Parameters for excessive speed deviation detection function (F1-)
Parameters for over-acceleration detection function (S3-)
Failure to do so will cause damage to the equipment.
If running a permanent magnet motor with any option cards other than the PG-F2 card, and not
using the braking sequence recommended by this Inverter, set the following braking sequences
externally.
After inputting the operational order, or closing the pole detection complete signal, release the braking.
A basket will be pulled by a counter weight. Be careful of this, as it can cause injury.
If running a permanent magnet motor with any option cards other than the PG-F2 card, note that
the Inverter has not been adapted for use with batteries. If so, do not select the battery as the
power source for an operation.
Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as
directed, such as reverses, doesn't work, or over-accelerates.

Trial Operation

WARNING
Check to be sure that the front cover is attached before turning ON the power supply.
An electric shock may occur.
Provide a separate fast stop switch; the Digital Operator STOP Key is valid only when its function is
set.
Injury may occur.
Reset alarms only after confirming that the RUN signal is OFF.
Injury may occur.

V
 CAUTION
Do not touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can
become very hot.
Otherwise, a burn injury may occur.
Be sure that the motor and machine is within the applicable ranges before starting operation.
Otherwise, an injury may occur.
Provide a separate holding brake if necessary.
Always construct the external sequence to confirm that the holding brake is activated in the event
of an emergency, a power failure, or an abnormality in the Inverter.
Failure to observe this caution can result in injury.
If using an Inverter with a elevator, take safety measures on the elevator to prevent the elevator
from dropping.
Failure to observe this caution can result in injury.
Do not check signals while the Inverter is running.
Otherwise, the equipment may be damaged.
Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.
Otherwise, the equipment may be damaged.

Maintenance and Inspection

WARNING
Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely
dangerous.
Doing so can result in electric shock.
Always have the protective cover in place when power is being supplied to the Inverter. When
attaching the cover, always turn OFF power to the Inverter through the MCCB.
Doing so can result in electric shock.
After turning OFF the main circuit power supply, wait for the time indicated on the front cover, and
make sure the CHARGE indicator light has gone out, and then perform maintenance and inspec-
tion.
The capacitor will remain charged and is dangerous.
Maintenance, inspection, and replacement of parts must be performed only by authorized person-
nel.
Remove all metal objects, such as watches and rings, before starting work. Always use grounded
tools.
Failure to heed these warning can result in electric shock.

Be sure to completely stop the permanent magnet motor before maintenance and inspection.
Failure to do so may result in electric shock.

CAUTION
A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully.
The CMOS IC can be destroyed by static electricity if touched directly.
Do not change the wiring, or remove connectors or the Digital Operator, during operation.
Doing so can result in personal injury.

Wiring the Main Circuits

This section describes wiring connections for the main circuit inputs and outputs.

Wiring Main Circuit Inputs

Observe the following precautions for the main circuit power supply input.

Installing Fuses
To protect the Inverter, it is recommended to use semiconductor fuses like they are shown in the table below.

 Installing a Moulded-case Circuit Breaker
When connecting the power input terminals (R/L1, S/L2, and T/L3) to the power supply using a moulded-case
circuit breaker (MCCB) observe that the circuit breaker is suitable for the Inverter.
Choose an MCCB with a capacity of 1.5 to 2 times of the Inverter's rated current.
For the MCCB's time characteristics, be sure to consider the Inverter's overload protection (one minute at
150% of the rated output current).

Installing an Earth Leakage Breaker

Inverter outputs use high-speed switching, so high-frequency leakage current is generated. If an earth leakage
2 breaker shall be used, select one which detects only the leakage current in the frequency range hazardous to
humans, but not high-frequency leakage currents.
When using a special-purpose earth leakage breaker for Inverters, choose one with a sensitivity current of
at least 30 mA per Inverter.
When using a general earth leakage breaker, choose one with a sensitivity current of 200 mA or more per
Inverter and with an operating time of 0.1 s or more.

Installing a Magnetic Contactor at the Input

If the power supply for the main circuit is shut off by a control circuit, a magnetic contactor can be used.
The following things should be considered:
The Inverter can be started and stopped by opening and closing the magnetic contactor on the primary side.
Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down.
Do not exceed one power up per hour.
When the Inverter is operated using the Digital Operator, automatic operation cannot be performed after
recovery from a power interruption.

Connecting Input Power Supply to the Terminal Block

The input power supply can be connected in any sequence to the terminals R, S or T on the terminal block; the
input phase sequence is irrelevant to the output phase sequence.

Installing an Input AC Reactor

If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase advancing
capacitor is switched nearby, an excessive peak current may flow through the input power circuit, causing the
Inverter to break down.
To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reac-
tor connection terminals.
This also improves the power factor on the power supply side.

Installing a Surge Absorber

Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include mag-
netic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

 Wiring Main Circuit Terminals

Wiring the Output Side of the Main Circuit

Observe the following precautions when wiring the main output circuits.

Connecting the Inverter and Motor

Connect output terminals U/T1, V/T2, and W/T3 according to the motor lead wires U, V, and W.
Check that the motor rotates forward with the Forward Run Command. Switch over two of the motor cable
wires and reconnect if the motor rotates in reverse with the Forward Run Command.

Never Connect a Power Supply to Output Terminals

Never connect a power supply to output terminals U/T1, V/T2, and W/T3. If a voltage is applied to the output 2
terminals, the internal circuits of the Inverter will be damaged.

Never Short or Ground Output Terminals

If the output terminals are touched with bare hands or the output wires come into contact with the Inverter
case, an electric shock or grounding may occur. This is extremely hazardous. Do not short the output wires.

Do Not Use a Phase Advancing Capacitor

Never connect a phase advancing capacitor to an output circuit. The high-frequency components of the
Inverter output may overheat and be damaged and may cause other parts to burn.

Using a Magnetic Contactor

Check the control sequence to make sure, that the magnetic contactor (MC) between the Inverter and motor is
not turned ON or OFF during Inverter operation. If the MC is turned ON while the Inverter is operating, a
large inrush current will be created and the Inverters overcurrent protection may operate.

Ground Wiring
Observe the following precautions when wiring the ground line.
Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 and that
of the 400 V Inverter with a ground resistance of less than 10 .
Do not share the ground wire with other devices, such as welding machines or power tools.
Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the
ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
When using more than one Inverter, be careful not to loop the ground wire.

When two or more Braking Units are connected in parallel, use the wiring and jumper settings like shown in
Fig 2.8. There is a jumper for selecting whether each Braking Unit is to be a master or slave. Select Master
for the first Braking Unit only, and select Slave for all other Braking Units (i.e. from the second Unit
onwards).

Control Power Supply Connection

The control board of the Inverter can be supplied by an external voltage source during emergency operation
using the twisted wires marked with P0 and N0. Upon shipment the wires are connected to the main circuit
terminals B1/+3 and -.
Refer to page 6-101, Emergency Operation for details about emergency operation.
Follow the example shown in Fig 2.9 when connect a backup power supply battery for the system.

 Wiring Control Circuit Terminals

Wire Sizes
For remote operation using analog signals, the control line length between the Analog Operator or operation
signals and the Inverter should be less than 30 m. Separate the lines from main power lines or other control
circuits in order to reduce induction from peripheral devices.
When setting frequency references from an external source (not from Digital Operator), used shielded twisted-
pair wires and ground the shield for the largest area of contact between shield and ground.

Wiring Method and Precautions

The wiring method is the same as the one used for straight solderless terminals. Observe the following precau-
tions when wiring.
Separate the control signal lines for the PG Speed Control Board from main circuit lines and power lines.
Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors
caused by noise. Also, do not use any lines that are more than 100 m long.
Connect the shield to the shield terminal (E).
Do not solder the ends of wires. Doing so may cause contact faults.
When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm.

Selecting the Number of PG (Encoder) Pulses

The setting for the number of PG pulses depends on the model of PG Speed Control Board being used. Set the
correct number for your model.

The Verify mode is used to display the parameters that have been changed from their factory settings, either by
programming or by autotuning. None will be displayed if no settings have been changed.
The parameter A1-02 is the only parameter from the A1- group, which will be displayed in the modified
parameter list if it has been changed before. The other parameters will not be displayed, even if they are differ-
ent from the factory setting.
In the verify mode, the same procedures as used in the programming mode can be used to change settings. Use
the Increment, Decrement, and Shift/RESET keys to change a setting. When the DATA/ENTER key is pressed
the parameter setting are written and the display returns to the Monitor display.

Autotuning Mode

Autotuning automatically measures and sets the required motor data in order to achieve the maximum perfor-
mance. Always perform autotuning before starting operation when using the vector control methods.
When V/f control has been selected, stationary autotuning for line-to-line resistance can be selected only.
When the motor cannot be operated (e.g. if the ropes cannot be removed from the traction sheave), and open-
loop or closed-loop vector control shall be used, perform stationary autotuning.

Example of Operation for V/f control

The tuning method for V/f control is fixed to the measurement of the terminal resistance (T1-01=1). Input the
the rated output power and the rated current specified on the nameplate of the motor and then press the RUN
key. The motor data are measured automatically.
Always set the above items. Otherwise autotuning cannot be started, e.g. it cannot be started from the motor 3
rated voltage input display.
A parameter can be changed from the setting displays using the Increment, Decrement, and Shift/RESET
keys. The parameter is saved when the DATA/ENTER key is pressed.

 Basic Settings
When using a permanent magnet motor, set the control mode to Closed-loop vector control (PM) (A1-02 = 6).
For more information on how the Digital Operator works, see Chapter 3. For more information on parameters
and their settings, refer to Chapter 5 and Chapter 6.

For permanent magnet motors do not use any other control mode than closed-loop vector control (PM) (A1-02 =
6). Using any other control mode can cause damage to the equipment or cause the machinery to behave errati-
cally.

 (3) Selecting which way the motor should rotate

The motor should be set so that when it rotates in the forward direction the elevator car goes up.
Torque compensation at start uses a 0 to +10 V analog signal fixed in the forward direction. The elevator
also requires positive torque compensation when ascending. The direction of the motor must be set so that
IMPORTANT the elevator goes up when the motor is rotating forwards.

The factory setting for the PG rotation is Phase B leads with a Forward Run Command (F1-05 = 1).
The motor is considered to be moving forwards if the shaft rotates counter-clockwise when looking from the
load side.
The motor wiring should be connected so that the elevator car goes up when the motor is rotating counter-
clockwise (i.e., in the forward direction). Wiring should be corrected if this is not the case.
Note: Follow the procedure below to change the direction of the motor so that it rotates clockwise looking from the load side of the shaft as the elevator car
goes up.
Step 1: Change the wiring between the motor and Inverter
Reconnect the wires so that the lines that ran to U, V, and W now run to U, W, and V.
Step 2: Change the following parameters.
PG rotation (F1-05)
Change the setting value from 1 (Phase B leads with a Forward Run Command) to 0 (Phase A leads with a Forward Run Command).

4
PG home position offset (E5-11)
Set the value to its additive inverse.
For example, when adjustments to the PG home position have already been made, multiply the PG home position value by negative one and
set that value.

(4) Verify the direction of motor rotation

Follow the procedure described below and have the speed detection value displayed on the Digital Operator
keypad screen. Be sure to verify the data provided in the table.
Rotate the motor shaft by hand to verify that the direction of rotation coincides with the polarity on the
Digital Operator screen.
Make sure the speed is properly displayed.

 (5) PG Encoder Home Position Pulse Adjustment
Procedure
When performing autotuning, select Magnet position autotuning (T1-01 = 4) and press the RUN key.
The Inverter will automatically begin assessing the amount of offset for the PG home position.
After tuning is complete the Inverter will automatically save the offset value for the PG home position to
parameter E5-11.
If tuning is interrupted or stopped before completion
The Inverter will abort the autotuning process if a fault occurs during autotuning, and no value will be
saved to parameter E5-11 (PG home position offset).
If a fault occurs during autotuning, refer to Chapter 7 Troubleshooting in order to solve the problem. After
taking the necessary corrective action, perform autotuning again to calculate the proper PG home position
offset.
Notes Prior to Performing Autotuning
Be sure to verify the following points prior to performing autotuning.
Autotuning automatically checks motor parameter settings.
This is the major difference when compared with the autotuning process used for a servo system (a servo

4
system checks the size of the load).
If the load is coupled with the motor when autotuning is performed (i.e., the rope is connected), motor
parameters may not be set properly, which can lead to erratic and potentially dangerous behavior of the
machine. Be absolutely sure to disconnect the load from the motor when performing autotuning.
Autotuning measures takes various measurements while rotating the motor and saves that data.
For this reason, the brake must be released prior to autotuning to allow the Inverter to rotate the motor. Be
sure that any contact switches are closed before attempting autotuning.
BB or BB1 signals (BB-SC) on the control terminal block that trigger baseblock should be closed so that
baseblock is released when autotuning the Inverter and motor.

(4) Setting Motor Parameters

Procedure
1. When performing autotuning, select Rotational autotuning (T1-01 = 0).
2. Enter the information as requested from either the motor nameplate or Test Report provided.
The Digital Operator will ask for the motor rated capacity, the base revolutions per minute (min-1), rated
voltage, rated current, number of motor poles, the d-axis inductance, induction voltage parameter, and
number of PG pulses per motor rotation.
If the Motor voltage parameter calculation selection is set to Automatic calculation (T2-10 = 1) then the
Inverter will set these values automatically, so there is no need to enter them yourself.
3. Press the RUN key once all data has been entered. All remaining motor data will be automatically calcu-
lated by the Inverter.
If autotuning completes without any trouble, the Inverter will automatically set the motor parameters
(E5-xx). Refer to related parameters.
If tuning is interrupted or stopped before completion
The Inverter will abort the autotuning process if a fault occurs during autotuning, and no values will be
saved to the motor parameters E5-xx.
If a fault occurs during autotuning, refer to Chapter 7 Troubleshooting in order to solve the problem.
After taking the necessary corrective action, perform rotational autotuning again to calculate the proper
motor parameters. 4

To control speed between 20% and 80% to ensure smooth gear operation and limit the maximum speed of
the machine, set d2-01 to 80.0% and set d2-02 to 20.0%.

 Performing a Trial Operation

No-load Operation
To being no-load operation (without connecting the machine and the motor), press the LOCAL/REMOTE Key
on the Digital Operator to change to Local mode (the SEQ and REF indicators on the Digital Operator should
be OFF).
Always confirm safety around the motor and machine before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter.
Jog Frequency Reference (d1-17, default: 8.00 Hz) can be started and stopped by pressing and releasing the
JOG Key on the Digital Operator. If the external sequence prevent operation from the Digital Operator, con-
firm that fast stop circuits and machine safety mechanisms are functioning, and then start operation in Remote
mode (i.e., with a signal from the control signal terminals). The safety precautions must always be taken
before starting the Inverter with the motor connected to the machine.

Both a Run Command (forward or reverse) and a frequency reference (or multi-step speed reference) must be
provided to start Inverter operation.
Input these commands and reference regardless of the operation method (i.e., LOCAL of REMOTE).
4
IMPORTANT

Loaded Operation
Connect the machine to the motor and then start operation as described for no-load operation (i.e., from the
Digital Operator or by using control circuit terminal signals).

Connecting the Load

After confirming that the motor has stopped completely, connect the mechanical system.
Be sure to tighten all the screws when securing the motor shaft to the mechanical system.

Operation using the Digital Operator

Use the Digital Operator to start operation in Local mode in the same way as in no-load operation.
If fault occurs during operation, make sure the STOP Key on the Digital Operator is easily accessible.
At first, set the frequency reference to a low speed of one tenth the normal operating speed.

Checking Operating Status

Having checked that the operating direction is correct and that the machine is operating smoothly at slow
speed, increase the frequency reference.
After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too
high.
Refer to page 4-23, Performance Optimization if hunting, vibration, or other problems originating in the
control system occur.

4-21
 Check and Recording User Parameters
Use verify mode (i.e., when the VERIFY indicator on the Digital Operator is lit) to check user parameters that
have been changed for trial operation and record them in a user parameter table.
Any user parameters that have been change by autotuning will also be displayed in verify mode.
If required, the copy function in parameters o3-01 and o3-02 displayed in advanced programming mode can
be used to copy the changed settings from the Inverter to a recording area in the Digital Operator. If changed
settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system
recovery if for any reason the Inverter has to be replaced.
The following functions can also be used to manage user parameters.
Recording user parameters
Setting access levels for user parameters
Setting a password

Recording User Parameters (o2-03)

If o2-03 is set to 1 after completing trial operation, the settings of user parameters will be saved in a separate
4 memory area in the Inverter. Later, after Inverter settings have been changed, the user parameters can be ini-
tialized to the settings saved in the separate memory area when o2-03 was set to 1 by setting A1-03 (Initialize)
to 1110.

User Parameter Access Levels (A1-01)

A1-01 can be set to 0 (monitoring-only) to prevent user parameters from being changed. A1-01 can also be set
to 1 (User-specified Parameters) and used along with A2 parameters to display only parameters required by
the machine or application in a programming mode.

Password (A1-04 and A1-05)

When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that user parameters will
be displayed only when the correct password is input.

Current Limitation

Carrier Frequency Setting

The carrier frequency selection has a direct influence on the motor noise. The higher the carrier frequency the
lower is the motor noise. On the other hand the overload capability of the Inverter is reduced with a higher car-
rier frequency. Both have to be considered when the setting is changed.

* 2. Can only be set when parameter C6-02 is set to 0F.
* 3. The factory settings depend on the Inverter capacity. The values for a 200 V class Inverter for 3.7 kW are given.

Carrier Frequency Selection

The factory setting is 8 kHz for units from 3.7 to 22 kW and 5 kHz for units from 30 to 55 kW. Usually the
value has not to be changed. However, if it necessary to change it, observe the following precautions:
If speed and torque oscillate at low speeds: Lower the carrier frequency.
If Inverter noise affects peripheral devices: Lower the carrier frequency.
If leakage current from the Inverter too is large: Lower the carrier frequency.
If metallic noise from the motor is large: Increase the carrier frequency.

 Carrier Frequency Derating and Current Limitation

Carrier Frequency and Inverter Overload Capability

The Inverter current rating depends on the carrier frequency setting. If the carrier frequency is increased the
rated current is decreased and vice versa like shown in Fig 6.1.
The overload capability is always 150% of the de- or updated Inverter current for 30 sec. If this over load limit
is exceeded the Inverter trips with an Inverter overload fault (OL2).

Fig 6.2 Low Frequency Current Limitation

If the torque at low frequencies is too low, check whether the current runs into the limitation explained
above. If so, check the motor data settings (E2-) and the V/f pattern (E1-).
If the current still runs into the limit it might be necessary to install a one size bigger Inverter.
IMPORTANT For selecting an Inverter please consider the low frequency current limit as described above and select
an Inverter with an appropriate current margin.

 EN81-1 Compliance
EN81-1 Conform Wiring with One Motor Magnetic Contactor
In order to use the L7B with one motor magnetic contactor instead of two while keeping compliance to the
EN81-1:1998, the following rules have to be followed:
The hardware baseblock function using the terminals BB and BB1 must be used to enable/disable the
Inverter.
If the elevator safety chain is opened, the Inverter output must be cut. This means that the baseblock sig-
nals at the terminals BB and BB1 must be opened, e.g. via an interposing relay.
The baseblock monitor function must be programmed for one of the multi-function outputs (H2- = 46/
47). The regarding multi-function contact must be implemented in the magnetic contactor supervision cir-
cuit of the controller in order to prevent a restart in case of an Inverter baseblock or motor magnetic con-
tactor malfunction.
All magnetic contactors must be conform to the EN81-1:1998.
Fig 6.3 shows an EN81-1:1998 wiring example.

To start in the elevator in Up or Down direction the following conditions have to be fulfilled:
At least one speed reference must be selected.
The hardware baseblock signal must be set (not baseblock condition).
When a multi-function contact input is set as magnetic contactor confirmation input, the magnetic contac-
tor confirmation signal must be present before the travel starts.
To start in the Up direction the Up signal must be set. To start in the Down direction the Down signal must
be set.

option card AI-14B is installed, the A1 signal is replaced by the Channel 1 input of the AI board.
The analog reference signal can also be used as 1st speed if multispeed operation is selected (d1-18=0, refer to
page 6-8, Speed Selection Sequence Using Multi-function Contact Inputs for details).
If parameter d1-18 is set to 0 and b1-01 is set to 1, the analog input value replaces any speed selected by the
multi-function contact inputs except the service speed.

Input the Speed Reference Using Memobus Communications (b1-01=2)

When b1-01 is set to 2 the speed reference can be input using Memobus communications.

If d1-18 is set to 2 and no multi-function contact input is set to nominal speed selection, the speed reference
with speed selection input set is nominal speed (d1-09). When the leveling speed signal is set, the Inverter
starts to decelerate to the leveling speed. The leveling speed signal has priority over all other speed signals, i.e.
the intermediate speed 1 and 2 and the releveling signals are disregarded when leveling speed is selected.
The Inverter can be stopped by removing the leveling speed signal or the Up/Down command.

Fast Stop
If a multi-function contact input terminal (H1-) is set to 15 or 17 (fast stop), this input can be used to fast
stop the Inverter in the case of emergency. In this case the fast stop deceleration time set in C1-09 is used. If
the fast stop is input with an NO contact, set the multi-function input terminal (H1-) to 15, if the fast stop
is input with an NC contact, set the multi-function input terminal (H1-) to 17.
After the Fast Stop Command has been input, the operation cannot be restarted until the Inverter has stopped.
To cancel the Fast stop, turn OFF the Run Command and Fast Stop Command.

Fig 6.4 Timing Chart of Brake Sequence Without Torque Compensation at Start

The timing chart above is divided in time zones. The following table explains the sequence in each time zone.
Timing Description
The Inverter gets the direction signal (UP/DOWN)
The Inverter gets the hardware baseblock disable signal (Not BB condition).

t1
The Inverter receives the speed reference signal.
The Inverter sets the magnetic contactor closed signal. 6
The Inverter waits for the magnetic contactor confirmation signal. If no multi-function contact input is set to magnetic
contactor confirmation signal (H1-=86), the sequence is proceeded after exceeding the operation start delay time (S1-
16).
When the RUN delay time (S1-16) has elapsed, DC injection (Open Loop) or zero-speed operation (Closed Loop) is
t2 started.
When the brake open delay time (S1-06) has elapsed, the Inverter sets the brake release command.
The Inverter keeps DC injection/zero-speed operation until
t3 * the time S1-04 S1-06 has elapsed if S1-06 < S1-04 or
* the time S1-06 has elapsed if S1-06 > S1-04 (try avoid this setting since the motor could be driven against the brake)
t4 The speed is increased to the selected speed and is kept parameter until the leveling speed is selected.
The speed is decreased to the leveling speed and is kept parameter until the stop signal is given (depending on d1-18 either
t5 by removing the direction signal, by removing the leveling signal or by deleting the speed inputs, see page 6-8, Speed
Selection Sequence Using Multi-function Contact Inputs)
6 The speed is decreased to the zero-speed level.
When the zero-speed level is reached, the DC injection (Open Loop) or zero-speed operation (Closed Loop) is applied for
t7 the time set in S1-05.
When the brake close delay time (S1-07) has elapsed, the brake release command is removed.
The Inverter continues DC Injection (Open Loop) or zero-speed operation (Closed Loop) until the time S1-06 S1-07 has
t8
elapsed. After that the Inverter output is shut down and the hardware baseblock signal must be set.
t9 After the magnetic contactor open delay time (S1-19) has elapsed, the magnetic contactor close signal is removed.

 Brake Sequence with torque compensation at start
(closed-loop vector control required)
If a load measuring device is installed in the elevator, an analog input can be used to input a torque compensa-
tion value to the Inverter. This function requires closed-loop vector control.
The input torque compensation value is latched when the direction command is given. At the start it is
increased from zero to the latched value using the torque increase time set in parameter S1-22. The torque
compensation value fades out to 0 after the speed has reached the torque compensation fade out level.
The torque compensation function can be adjusted using the parameters shown in the block diagram below.
Adjust the parameter so that the torque compensation value is zero when the elevator is balanced.

A1 function is selected for torque compensation (H3-15=1)
the channel Ch1 of an AI-14B option card can be used, if b1-01 is not set to 1 (speed reference source is
not the A1 input) and the A1 function is selected for torque compensation (H3-15=1)

6 one of the input channels Ch2 or Ch3 of an AI-14B option card can be used when the input function for is
set to Torque Compensation (H3-05 or H3-09=14). The setting of b1-01 has no influence here.

 Control/Brake Sequence

The timing chart above is divided in time zones. The following table explains the sequence in each time zone
Timing Description
The Inverter gets the direction signal (UP/DOWN)
The Inverter gets the hardware baseblock signal disable signal (Not BB condition).
The Inverter receives the speed reference signal.
t1
The Inverter sets the magnetic contactor close signal.
The Inverter waits for the magnetic contactor confirmation signal. If no multi-function contact input is set to magnetic con-
tactor confirmation signal (H1-=86), the sequence is proceeded after exceeding the operation start delay time (S1-16).
The zero-speed control operation is started.
The analog torque compensation input is latched and the torque compensation value is increased from zero to the latch
t2
value using the time parameter set in parameter S1-22.
After reaching the torque compensation level at start, the Inverter sets the brake release command.
t3 The brake opens and the zero-speed operation is continued until S1-04 has elapsed.
The speed is increased to the selected speed and is kept parameter until the leveling speed is selected.
t4 During acceleration, when the torque fade out speed level S1-29 is reached, the torque compensation value is fade out to 0
using the time parameter set in S1-22.
The speed is decreased to the leveling speed and is kept parameter until the stop signal is given (depending on d1-18 either
t5 by removing the direction signal, by removing the leveling signal or by deleting the speed inputs, see page 6-8, Speed Selec-
tion Sequence Using Multi-function Contact Inputs).
t6 The speed is decreased to the zero-speed level.
When the zero-speed Level is reached, zero-speed operation is applied for the time set in S1-05.
t7
When the brake close delay time (S1-07) has elapsed, the brake release command is removed.
The Inverter continues the zero-speed operation until the time S1-06 S1-07 has elapsed. After that the Inverter output is
t8
shut down and the hardware baseblock signal must be set.
t9 After the magnetic contactor open delay time (S1-19) has elapsed, the magnetic contactor close signal is removed.

Principle
The short floor operation is activated when the leveling signal is set before the nominal speed is reached. The
Inverter calculates the distance for deceleration from nominal speed to 0.4 x the nominal speed, which is equal
to the area S in the figure below.
Speed

Nominal speed

S
Nominal speed x 0.4

Leveling speed

There are two ways of operation:

6-21
 If the leveling speed signal is set when minimal 40% of the nominal speed have been reached, the Inverter
keeps the reached speed for the distance equal to the area S. After that it decelerates to the leveling speed.
If the leveling signal is set before 40% of the nominal speed have been reached, the Inverter accelerates to
40% of the nominal speed and keeps it for the distance equal to the area S. After that it decelerates to lev-
eling speed.
Speed

40% nominal speed

0 t

Parameter Setup
The short floor function can be activated by setting parameter S3-01 to 1.
When parameter d1-18 is set to 1 or 2 (dedicated speed inputs), the value of parameter d1-09 is taken as nom-
inal speed.

 Acceleration and Deceleration Characteristics

Acceleration and Deceleration Characteristics

Setting Acceleration and Deceleration Times

The acceleration time indicates the time to increase the speed from 0% to 100% of the maximum speed set in
E1-04. The deceleration time indicates the time to decrease the speed from 100% to 0% of E1-04.
Four separate acceleration and deceleration times can be set. They can be switched over between using:
multi-function contact input signals
the automatic accel./decel. time switch over function with a changeable switching speed level
The display unit and the setting range for the times can be selected between 0.0 sec. or 0.00sec.

Switching Over the Acceleration and Deceleration Time Using Multi-Function Input
Commands
When two multi-function contact input terminals are set to Accel./Decel. time switch over 1 and 2 (H1-
=7 and 1A), the acceleration/deceleration times can be switched over even during operation by a binary
combination of the inputs. The following table shows the acceleration/deceleration time switching combina-
tions.

Automatic Deceleration Time Switch Over Using a Speed Level

The deceleration times C1-02 and C1-08 can be switched over automatically at a certain speed which can be
set in parameter C1-11. Fig 6.6 shows the working principle of the function.
Set C1-11 to a value other than 0.0 Hz. If C1-11 is set to 0.0 Hz, the function will be disabled.

Dwell at Start Function (Closed-loop vector only)

The dwell function can be used to improve the start behavior when the static friction is high.
After the start command has been set, the output speed is increased up to the Dwell speed set in parameter S1-
26 using the acceleration time C1-07. As soon as the motor speed (PG feedback) reaches the acceleration time
switching level C1-11, the acceleration is continued using the selected acceleration time.

 Stall Prevention During Acceleration
The Stall Prevention During Acceleration function prevents the motor from stalling if the load is too heavy.
If L3-01 is set to 1 (enabled) and the Inverter output current reaches 85% of the set value in L3-02, the accel-
eration rate will begin to slow down. When L3-02 is exceeded, the acceleration will stop.
If L3-01 is set to 2 (optimal adjustment), the motor accelerates so that the current is held at the level set in L3-
02. With this setting, the acceleration time setting is ignored.

Setting Precautions
Set the parameters as a percentage taking the Inverter rated current to be 100%.
Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the Inverter
lifetime. Also do not disable the function.
If the motor stalls with the factory settings check the V/f pattern settings (E1-) and the motor setup
(E2-). 6
If the stall level has to be increased very much to get the elevator running, consider to use a one size bigger
Inverter.

Droop Control Function

Droop control is a function that allows the user to set the amount of motor slip.
When a single load is operated with two motors (such as in a crane conveyor), a high-resistance motor is nor-
mally used. This is to use torque characteristics that exhibit proportion movements due to changes in the sec-
ondary resistor to maintain torque balance with the load and overall speed balance with the load.
If droop control is used, a high-resistance motor characteristics can be set for a general-purpose motor.
The balance of the load is very different with different amounts of slip.

Reducing the Motor Speed Fluctuation (Slip Compensation Function)

When the load is large, the motor slip also increases and the motor speed decreases. The slip compensation
function keeps the motor speed parameter, regardless of changes in load. When the motor is operating at the
rated load, parameter E2-02 (Motor Rated Slip) the slip compensation gain value in parameter C3-01 is
added to the output frequency. The function can be used in V/f control or open-loop vector control.

Adjusting Slip Compensation Gain (C3-01)

If C3-01 is set to 1.0, the slip compensation value at 100% load is equal to the rated slip set in parameter
E2-02.
If necessary (motor speed is too high or too low) adjust the slip compensation gain as follows:
1. With open-loop vector control set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current). The
motor rated slip can be calculated using the values on the motor nameplate and the following formula:
Rated motor speed (rpm) Number of motor poles
(Hz) = Motor rated frequency (Hz) -------------------------------------------------------------------------------------------------------------------------------
120
The motor data can be set automatically using the autotuning function.
2. With V/f control set C3-01 to 1.0.
3. Apply a load and compare the speed reference and the actual motor speed during run with parameter
speed. Adjust the slip compensation gain by 0.1 at a time. If the speed is less than the target value, increase
the slip compensation gain, if the speed is higher than the target value, reduce the slip compensation gain.
4. Setting C3-01 to 0.0 disables the slip compensation function.

Adjusting Slip Compensation Primary Delay Time Parameter (C3-02)

The slip compensation delay time parameter is set in ms. The setting value of C3-02 is 2000ms. Normally,
there is no need to change these settings. When the slip compensation responsiveness is low, lower the set
value. When the speed is unstable, increase the set value.

6-37
 Adjusting Slip Compensation Limit (C3-03)
Using parameter C3-03 the upper limit for the slip compensation can be set as a percentage, taking the motor
rated slip as 100%.
If the speed is lower than the target value but does not change even after adjusting the slip compensation gain,
the slip compensation limit may have been reached. Increase the limit, and check the speed again. Always
make sure that the value of the slip compensation limit and reference frequency does not exceed the tolerance
of the machine.
The following diagram shows the slip compensation limit for the parameter torque range and fixed output
range.

Operation Selection when the Output Voltage Saturated (C3-05)

6 Generally the Inverter cannot output a voltage that is higher than the input voltage. If in the high-speed range
the output voltage reference for the motor (monitor parameter U1-06) exceeds the input voltage, the output
voltage becomes saturated, and Inverter cannot respond to speed or load changes. This function automatically
reduces the output voltage to avoid voltage saturation.
Thereby the speed control accuracy can be maintained even at high speeds (around the rated speed of the
motor). By the lowered voltage the current can be around 10% higher compared to the operation without volt-
age limiter.

6-38
 Improving the Operation Performance

Torque Compensation Function Adjustments

The torque compensation function detects a rising motor load, and increases the output torque.
In V/f control the Inverter calculates the motor primary loss voltage using the terminal resistance value (E2-
05) and adjusts the output voltage (V) to compensate insufficient torque at startup and during low-speed oper-
ation.
The compensation voltage is calculated by the calculated Motor primary voltage loss parameter C4-01.
In open-loop vector control the motor excitation current and the torque producing current are calculated and
controlled separately. The torque compensation affects the torque producing current only.
The torque producing current is calculated by the calculated torque reference C4-01.

The compensation works for motoring operation only. It can not be used for regenerative operation.
If the starting torque compensation is used and a large shock is generated at the start, increase the starting
torque compensation time parameter (C4-05)

Automatic Speed Regulator (ASR) (Closed-loop Vector only)

In closed-loop vector control the automatic speed regulator (ASR) adjusts the torque reference in order to
eliminate the deviation between the speed reference and the measured speed (PG feedback). The ASR settings

ASR Gain and Integral Time Adjustments

There are three sets of ASR gain and integral times, one for the maximum speed (C5-01/02), one for the mini-
mum speed at acceleration (C5-03/04) and one for the minimum speed at deceleration (C5-09/10) (see the fig-

During Acceleration During Deceleration

When the ride starts with the nominal speed selected, the ASR P gain and I time change from C5-03/04 to C1-
01/02 at nominal speed. When the speed selection changes to leveling speed, the P gain and I time are changed
from C1-01/02 to C1-09/10.

6-42
 Improving the Operation Performance

If parameter d1-18 is set to 0, the nominal/leveling speed detection function must be enabled in order to use
the ASR 3 settings.

Adjusting ASR Proportional Gains (C5-01/03/09)

The gain settings determine how much the ASR input (= speed deviation) is amplified in order to eliminate the
speed deviation. The responsiveness of the ASR is increased when the gain setting is increased but oscillations
can occur when this setting is too high.
Increase C5-01 if the ASR is too slow at start or very low frequencies, decrease it if vibrations occur.
Increase C5-03 if the ASR is too slow at high speed or if overshooting occurs at speed changes in the high
speed area, decrease it if vibrations occur
Increase C5-09 if ASR is slow in the low speed area or if undershooting occurs at leveling speed. If vibra-
tions occur in the low speed area during deceleration decrease the value.

Adjusting ASR Integral Times (C5-02/04/10)

The integral time determines how fast the ASR input is integrated in order to eliminate the speed deviation.
Lengthening the integral time lowers the responsiveness of the ASR and the speed accuracy when the load
changes suddenly. Oscillations can occur if the setting of this value is too low.
Decrease C5-02 if a speed deviation is compensated too slow at high speeds or if overshooting occurs at
speed changes in the high speed area. Increase it if vibrations occur.
Decrease C5-04 if a speed deviation is compensated too slow at start or at very low frequencies. Increase it
if vibrations occur.
Decrease C5-10 if a speed deviation is compensated too slow in the low speed area or if undershooting
occurs at leveling speed. If vibrations occur in the low speed area during deceleration increase the value.

 Improving the Operation Performance

The timing chart above is divided in time zones. The following table explains the sequence in each time zone.
Timing Description
The Inverter receives a direction signal indicating up or down.
The Inverter receives a signal to disable hardware baseblock (i.e., a signal indicating there is no baseblock condition).
The Inverter receives the speed reference.
t0-t1
The Inverter receives a signal to close the magnetic contactor.
The Inverter waits for verification that the magnetic contactor has closed. If no multi-function input has been programmed to
issue a command verifying that the magnetic contactor has closed, then the Inverter will proceed to the next step once the time
set to S1-16 has passed (Run delay time).
Zero-servo operation begins.
Analog torque compensation value is maintained and the Inverter begins generating torque compensation based on S1-22 (Start-
t1-t2 ing torque compensation increase time).
Once the torque compensation reaches the specified level at start, the Inverter then releases the brake and maintains the torque
compensation value until it stops.
After the time set to S1-04 has expired (DC braking at start, or DC excitation), the Inverter begins to accelerate the motor.
t2-t3
The Dwell function can be enabled at start.
t3-t4 Inverter begins to accelerate.
t4-t5 The Inverter speed reaches the specified speed reference.
t5-t6 The Inverter begins to accelerate.
t6-t7 Zero-speed is selected.
The Inverter reaches the zero-speed level.
The Inverter continues using zero-speed control.
t7-t8 After the time set to S1-07 passes (Brake close delay time), the Inverter issues a command to close the brake.
After the time set to S1-07 passes (Brake close delay time), the Inverter issues a command to close the brake.
The Inverter continues operating with zero-speed until the time set to parameters S1-05 and S1-07 have passed.
The signal indicating direction is disabled.
t8-t9 Torque is reduced by the specified bias level: (300%) / (S1-31)
The Inverter halts output once the torque compensation level drops to zero.
The hardware baseblock signal is switched on.

t9-t10
Once the time set to S1-19 passes (Magnetic contactor open delay time), the Inverter will shut off the magnetic contactor control
signal. 6

Stabilizing Speed (Automatic Frequency Regulator) (Open-loop Vector)

The speed feedback detection control (AFR) function controls the stability of the speed when a load is sud-

Motor acceleration time (n5-02)

The motor acceleration time n5-02 is the time, which is needed to accelerate the to the rated speed with the
rated torque of the motor. The time can be estimated like follows:
Make the general setup (V/f pattern, Motor Setup, etc.)
Balance the elevator (car in middle position, Car weight = Counter weight)
Set the torque limits to 100% using the L7- parameters.
Set the acceleration time very short (the Inverter must reach the torque limit very fast).
Start in any direction and measure the time from zero-speed to top speed.
Set this time in n5-02.

Feed Forward Gain (n5-03)

This value usually has not to be changed.
Increase the time to improve the responsiveness to the speed reference
Decrease the time if vibrations occur

Improving the Leveling Accuracy by Slip Compensation

This function can be used in V/f and open-loop vector control to improve the leveling accuracy by compensat-
ing the motor slip influence at low speed.
The Inverter measures the current level or torque reference 1.0 s after the speed-agree condition (acceleration
finished) for 0.5 s and calculates the average value to estimate the load. This value is used for the calculation
6 of slip which is added to the speed reference at leveling speed (see Fig 6.19).

Adjustments
The Slip compensation values can be set separately for motoring and regenerative operation. Before adjusting
this function the general setup should have been done (Motor Setup, V/f pattern, Speeds, ASR settings etc.).
To adjust the Slip compensation function do the following in motoring and regenerative mode:
Set the motor speed in S2-01 if V/f control is used.
Try to measure the actual motor speed during leveling.
If the motor speed is lower than the leveling speed reference increase S2-02 in motoring mode or decrease
S2-03 in regenerative mode.
If the motor speed is higher than the leveling speed reference decrease S2-02 in motoring mode or increase
S2-03 in regenerative mode.

Field Forcing
The field forcing function controls the motor flux and compensates the flux establishment delay of the motor.
Thereby it improves the motor responsiveness to changes in the speed reference or the load.
Field forcing is applied during all operation conditions except DC Injection.
Using parameter d6-06 a field forcing limit can be applied. A setting of 100% is equal to the no-load current
set in parameter E2-03.

Adjusting the DC Injection Current Levels (S1-02/03)

Two different DC injection current levels can be set to start and stop.
Increase the corresponding set value when the holding torque during brake open or brake close is too low.
Decrease the corresponding set value when the holding torque is enough but e.g. the DC injection noise is
too loud.

Adjusting the DC Injection Gains for Stop (S1-17/18)

In open-loop vector control two different DC injection current gains for motoring and regenerative operation
can be adjusted in order to improve the stopping behavior. The gains are related to the S1-03 set value. The
function can be used to equalize jerk effects if the DC injection is too low with motoring load and too high
with regenerative load. The load condition (regenerative or motoring) is detected when the Inverter is running
at another speed than the leveling speed.
If the DC injection is ok with motoring load but not with regenerative load adjust parameter S1-17.
If the DC injection is ok with regenerative load but not with motoring load adjust parameter S1-18.

If S3-08 = 1, the output phase order will be U-W-V

Change Motor Direction in Closed-loop Vector Control

If closed-loop vector control for induction motors or permanent magnet motors is used, besides changing
parameter S3-08 the encoder direction has to be changed by setting F1-05.

Preventing Motor Stalling During Operation

Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter out-
put frequency when a transient overload occurs while the motor is operating at a parameter speed.
Stall prevention during operation can be enabled in V/f control only. If the Inverter output current continues to
exceed the setting in parameter L3-06 for 100 ms or longer, the motor speed is reduced. Enable or disable the
stall prevention using parameter L3-05. Set the according deceleration times using C1-02 (Deceleration time
1) or C1-04 (Deceleration Time 2).
If the Inverter output current reaches the set value in L3-06 2%, the motor will accelerate again to the set fre-
quency.

Setting Precautions
Set the parameters as a percentage taking the Inverter rated current to be 100%.
Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the Inverter
lifetime. Also do not disable the function.
If the motor stalls with the factory settings check the V/f pattern (E1-) and the motor setup (E2-).
If the stall level has to be increased very much to get the elevator running, check the mechanical system or
consider using a one size bigger Inverter.

Motor Torque Detection/Car Stuck Detection

The Inverter provides a torque detection function to detect overtorque (Car stuck) or undertorque. An alarm
signal can be output to the multi-function contact output terminals M1-M2, M3-M4, or M5-M6.
To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection NO/
NC) in one of the parameter H2-01 to H2-03 (multi-function contact output terminals M1 to M6 function
selection).
Overtorque/undertorque is detected by:
observing the output current in V/f control (the Inverter rated output current is equal to 100%).
observing the torque reference value in open-loop and closed-loop vector control (the motor rated torque is
equal to 100%).

The Overtorque detection function can be used to detect a stuck car. The torque detection function 1 can be
used for this. Therefore a multi-function contact output has to be set to Overtorque detection 1 (H2- = B
or 17). Using this with the factory settings a car stuck is detected (output is switched) when the torque/current
is higher than 150% for 10 sec. The level can be adjusted in L6-02, the time in L6-03. The output is switched
of and an OL3 fault will be indicated (see Fig 6.22)

Using a Multi-function Contact Output To Signalize Operation at the Torque Limit

If a multi-function output is set to this function (H2-01 to H2-03 is set to 30), the output is switched ON
when the motor output torque reaches one of the torque limits.

Enabling Integral Torque Limit Operation (L7-06 and L7-07)

In open-loop vector control an integral operation can be applied to the torque limit function (P-control is stan-
dard). This improves the torque limit responsiveness and smooths the torque limit operation. To enable the
integral operation set parameter L7-07 to 1. The integral time parameter can be set in parameter L7-06.

Setting Precautions
When the output torque reaches the torque limit, control and compensation of the motor speed is disabled
6 to prevent the output torque from exceeding the torque limit. The torque limit has the priority.
The torque limit accuracy is 5% at an output frequency of 10 Hz or above. When output frequency is
lower than 10 Hz, the accuracy is lower.

Internal Cooling Fan Failure OH1 Detection

Use the parameter setting to select the operation of the motor after a cooling fan fault occurs. This function can

Setting the Motor Rated Current (E2-01)

Set the rated current value on the motor nameplate in parameters E2-01 (for motor 1). This set value is the
base current for the internal thermal overload calculation.

Setting Motor Overload Protection Characteristics (L1-01) 6

Set the overload protection function in L1-01 according to the used motor.
The induction motor's cooling abilities vary with the motor type. Consequently, you must select the electronic
thermal protection characteristics.
Set L1-01 to:
0: to disable the thermal motor protection function.
1: to enable the thermal motor protection for a fan cooled general purpose motor (self-cooled).
2: to enable the thermal motor protection for an Inverter motor (externally cooled).
3: to enable the thermal motor protection for a special vector motor (externally cooled).

 Setting Motor Protection Operation Time (L1-02)
The motor protection operation time is the time for that the motor can handle a 150% overload when it was
running with the rated load before (i.e. operating temperature was reached before applying the 150% over-
load). Set the motor protection operation time in L1-02. The factory setting is 60 sec.

Setting a Motor Overload Pre-Alarm

If the motor overload protection function is enabled (i.e., L1-01 is set to a value different from 0) and H2-01 is
set to H2-03 (output terminals M1-M2, M3-M4, and M5-M6 function selection) to 1F (motor overload OL1
pre-alarm), the motor overload pre-alarm will be output at the selected terminals. If the electronic thermal
value reaches minimum 90% of the overload detection level, the output terminal that has been set will be
turned ON.

6 Output Current Observation

The Inverter can observe the output current and thereby detect if something is wrong in the sequence or with
the motor connection. There are two observer functions, one for the start and one during run.

 Inverter Protection

Inverter Overheat Protection

The Inverter is protected against overheating using a thermistor that detects the heatsink temperature.
When the overheat temperature level is reached the Inverter output is switched off.
To prevent a sudden and unexpected stop of the Inverter due to an over temperature, an overheat pre-alarm can
be output. The temperature level for that pre-alarm can be set in parameter L8-02. Using parameter L8-03 the
Inverter operation when an over temperature occurs can be selected.
If a multi-function output is set to this function the output is switched ON when the heatsink temperature
exceeds the overheat pre-alarm level set in L8-02.

Output Open Phase Protection

This function detects an open output phase by comparing the output current value of each phase with the out-
put open phase detection level (5% of Inverter rated current). The detection does not work when the output
frequency is below 2% of the base frequency.
Three settings are available:
L8-07=0, no output open phase detection
L8-07=1, the loss of one phase is detected only
L8-07=2, the loss of 2 or 3 phases is detected as well
The detection delay time can be set in parameter L8-20.

Adjusting the Over Acceleration Detection

Over acceleration is detected when the acceleration of the car exceeds the value set in S3-16 for longer than
the time set in S3-17. The setting of parameter S3-18 decides whether the over acceleration detection is always
on when the power supply is on (S3-18 = 0) or only during operation (S3-18 = 1).

Setting parameter S3-16 to 0.0 m/s disables the over acceleration detection.

It is imperative to set up the parameters S3-13 (Traction sheave diameter) and S3-14 (Roping) in
order to make this function working properly.

Closing the Inverter Output (Baseblock)

Using a baseblock command the Inverter output can be cut immediately. There are two baseblock functions
available, a hardware baseblock and a software baseblock.

Hardware Baseblock
When hardware baseblock is activated, the power supply of the IGBT driver circuit is cut off and the motor
starts to coast. If the baseblock command is cleared, the Inverter output operation is resumed.
To use this baseblock function the multi-function contact input S8 must be used. The input is a NC input, i.e. if
terminal S8 is open, the Inverter is baseblocked.

Software Baseblock
When software baseblock is used, the Inverter output is cut by a software function. If the baseblock command
is cleared, the Inverter output operation is resumed.
To use this baseblock function one of the multi-function contact inputs must be set to baseblock, i.e. one of the
parameters H1-01 to H1-05 (multi-function contact input terminal S3 to S7 function selection) must be set to 8
or 9 (Baseblock command NO/NC). The input can be used with a NC as well as with a NO contact.

Stopping the Inverter on External Device Errors (External Fault Function)

The external fault function activates the fault contact output and stops the Inverter operation. Using this func-
tion the Inverter operation can be stopped by the break down of peripheral devices or other external errors.
The digital operator will display EFx (External fault [input terminal Sx]). The x in EFx shows the number of
the terminal at which the external fault signal is input. For example, if an external fault signal is input to termi-
nal S3, EF3 will be displayed.
To use the external fault function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05
(multi-function contact input terminal S3 to S7 function selection).
Select the set value for H1-01 to H1-05 by a combination of any of the following three conditions.

Using the Timer Function

The multi-function contact input terminals S3 to S7 can be used as a timer function input and the multi-func-
tion output terminals M1-M2, M3-M4, and M5-M6 can be used as a timer function output. By setting the
delay time, you can prevent chattering of the sensors and switches.
Set one of the parameters H1-01 to H1-05 (multi-function contact input terminal S3 to S7) to 18 (timer

 Magnetic Position Detection Status Signal
When running a permanent magnet motor without a PG-F2 option card, an external braking sequence needs to
be set up if not using the recommended braking sequence. This will ensure that the brake does not get released
when the magnetic position detection status signal opens.
The magnetic pole detection status switch is open when the unit is powered up. The three types of conditions
that will trigger the magnetic position detection process are provided below.
The magnetic position detection signal will close once the process is complete.

E2-04 is displayed only when closed-loop vector control method is selected. Set the number of motor poles as
written on the motor nameplate.

Motor Line-to-Line Resistance Setting (E2-05)

E2-05 is set automatically when performing motor line-to-line resistance autotuning. When you cannot per-
form tuning, consult the motor manufacturer for the line-to-line resistance value. Calculate the resistance from
the line-to-line resistance value in the motor test report using the following formula, and then make the setting
accordingly.
E-type insulation: [Line-to line resistance () at 75C of test report] 0.92 ()

Autotuning
Autotuning sets motor parameters automatically. Therefore some motor data which are usually written at the
nameplate must be input and the autotuning has to be performed.

1. If the magnetic contactors are controlled by the Inverter, they will be closed during autotuning. If the
magnetic contactors are controlled by an external controller, make sure to close the contacts during
autotuning.
2. Make sure to close the baseblock contact during autotuning. Otherwise the autotuning can not be
IMPORTANT
started and will terminate with a minor fault.
3. For rotating autotuning make sure that the brake is open during autotuning.
4. Never do rotating autotuning with the ropes installed.

Setting the Autotuning Mode

One of the following three autotuning modes can be set.
Rotating autotuning
Non-rotating autotuning
Non-rotating autotuning for line-to-line resistance only

Rotating Autotuning (T1-01 = 0)

6
Rotating autotuning can be used for open-loop and closed-loop vector control only. Set T1-01 to 0, input the
data from the motor nameplate, and then press the RUN key on the Digital Operator. The Inverter will operate
the motor for approximately 1 minute and set the required motor parameters automatically.

Use this tuning mode only, if the motor can rotate freely which means that the ropes have to
be removed. The gearbox can remain connected to the motor.

IMPORTANT

Stationary Autotuning (T1-01 = 1)

Stationary autotuning is used for open-loop vector control and closed-loop vector control. Set T1-04 to 4, and
Motor no-load current (T1-09) will be added as a setting item. Input the data from the nameplate. Be sure to
input the value or motor no-load current (motor exciting current) from motor examination results to T1-09.
After autotuning, the value of T1-09 will be written in E2-03. When not setting T1-09, the value of Yaskawa
standard motors no-load current will be written in E2-03.

1. Power will be supplied to the motor when stationary autotuning is performed even though the
motor will not turn. Do not touch the motor until autotuning has been completed.
2. When performing stationary autotuning connected to a conveyor or other machine, ensure that the
IMPORTANT holding brake is not activated during autotuning.

6-79
 Non-rotating Autotuning for Line-to-Line Resistance (T1-01 = 2)
Non-rotating autotuning for line-to-line resistance can be used in any control method. It is the only possible
autotuning for V/f control.
To perform autotuning in V/f control, set T1-02 (Motor rated power) and T1-04 (Motor rated current) and then
press the RUN key on the Digital Operator. The Inverter supplies power to the motor for approximately 20
seconds to measure the motor line-to-line resistance and cable resistance. The motor does not turn during this
autotuning.

1. Power will be supplied to the motor when stationary autotuning 1 is performed even though the
motor will not turn. Do not touch the motor until autotuning has been completed.
2. When performing stationary autotuning 1 connected to a conveyor or other machine, ensure that
IMPORTANT the holding brake is not activated during autotuning.

Precautions Before Using Autotuning

Read the following precautions before using autotuning.
Use non-rotating autotuning whenever the load cannot be disconnected from the motor (e.g. the ropes cant
be removed).
Use rotating autotuning whenever performing autotuning when high precision is required or for a motor
that is not connected to a load.
If the wiring between the Inverter and motor changes by 50 m or more perform non-rotating autotuning for
line-to-line resistance.
If the motor cable is long (50 m or longer), perform non-rotating autotuning for line-to-line resistance.
If a mechanical brake is used, make sure, that it is not opened for non-rotating autotuning. Make sure that
it is opened for rotating autotuning.
Power is supplied to the motor when non-rotating autotuning is performed even though the motor does not

6 turn. Do not touch the motor until autotuning has been completed.
To cancel autotuning, press the STOP key on the Digital Operator.
Do not to rotating autotuning with the ropes installed.

Precautions for Rotating and Non-rotating Autotuning

If the motor rated voltage is higher than the power supply voltage, lower the base voltage value like shown in
Fig 6.29 to prevent saturation of the Inverters output voltage. Use the following procedure to perform auto-
tuning:
1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).
2. Input the results of the following formula to T1-05 (Motor base frequency):

T1-03
T1-05 = Base frequency from motor nameplate -----------------------------------------------
Motor rated voltage

 Motor and V/f Pattern Setup

3. Perform autotuning.
After the completion of autotuning, set E1-04 (Max. output frequency) to the base frequency from the motors
nameplate.

When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor
rated voltage) to the input power supply voltage 0.9. In this case at high speeds the output current will
increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter cur-
rent.

Precautions after Rotating and Non-rotating Autotuning

If the maximum output frequency and base frequency are different, set the maximum output frequency 6
(E1-04) after autotuning.

Set o2-01 to 1 to enable the LOCAL/REMOTE Key on the Digital Operator.
If the key is enabled, the frequency reference source and the Run Command source can be switched over
between LOCAL (Operator) and REMOTE (b1-01/02 setting).

Disabling the STOP Key (o2-02)

This parameter is used to set if the STOP key on the operator is active during remote control (b1-02 0) or
not.
If o2-02 is set to 1, a Stop Command from the operators STOP key is accepted. If o2-02 is set to 0 it is disre-
garded.

6-87
 Saving Parameters (o2-03)
The Inverter parameter setting values can be saved as user-set parameter initial values by setting parameter o2-
03 to 1.
To initialize the Inverter using the user-set initial values, set parameter A1-03 to 1110. To clear the user-set ini-
tial values set o2-03 to 2.

Changing the Inverter Capacity Setting (o2-04)

The Inverter capacity setting can be set using parameter o2-04. Refer to page 5-66, Factory Settings that
Change with the Control Method (A1-02) to see parameters that depend on this setting.
Normally it is not necessary to change this setting, unless the control board has been changed.

Setting the Frequency Reference using the UP and DOWN Keys without Using the
Enter Key (o2-05)
This function is active when frequency references are input from the Digital Operator. When o2-05 is set to 1,
the selected frequency reference can be incremented and decremented the UP and DOWN keys without using
the Enter key. The function work only if parameter b1-01 is set to 0.

Operation Selection when the Digital Operator is Disconnected (o2-06)

This function selects the operation when the digital operator gets disconnected when a Run Command is
active.
If o2-06 is set to 0 the operation is continued.
If o2-06 is set to 1 the output is switched off and the motor coasts to stop. The fault contact is operated. When
the operator is reconnected an OPR (Operator disconnected) is shown.

Cumulative Operation Time (o2-07 and o2-08)

6 The Inverter has a function that counts the operation time of the Inverter cumulatively.
Using parameter o2-07 the accumulated operation time can be changed, e.g. after a replacement of the control
board. If parameter o2-08 is set to 0, the Inverter accumulates the time, whenever the power supply is switched
ON. If o2-08 is set to 1, the time when a Run Command is active is counted only. The factory setting is 0.

Cooling Fan Operation Time (o2-10)

This function counts the operating time of the Inverter mounted fan cumulatively.
Using parameter o2-10 the counter can be reset, e.g. when the fan has been replaced.

Fault Trace Initialize (o2-12)

This function can be used to initialize the fault trace by setting parameter o2-12 to 1.

Number of Travels counter Initialize (o2-15)

Using this parameter the elevator operation counter monitor (U1-55) can be initialized.

 Digital Operator/LED Monitor Functions

Copying Parameters (JVOP-160 only)

The Digital Operator can perform the following three functions using a built-in EEPROM (non-volatile mem-
ory).
Store Inverter parameter set values in the Digital Operator by setting o3-01 to 1 (READ)
Write parameter set values stored in the Digital Operator to the Inverter by setting o3-01 to 2 (COPY)
Compare parameter set values stored in the Digital Operator with Inverter parameters settings by setting
o3-01 to 3 (VERIFY)
The data saved in the operator can be protected from overwriting by setting parameter o3-02 to 0. In this case
a READ command can not be executed. If it is nevertheless still done, PrE will be displayed at the operator.

E5-04 Number of motor poles F1-21 Absolute encoder resolution
E5-05 Motor line-to-line resistance F1-22 Magnet position offset

Saving Parameters Into the Encoder Memory

To save parameters in the encoder memory, the encoder write protection must be off (F1-26 = 1) and the
parameter F1-25 has to be set to 1 (ERED, INVENC WRITING is displayed during the save process).
The display of F1-25 automatically returns to 0 when the operation is finished (ERED, WRITE COM-
PLETE is displayed). If any fault occurs the fault code will be displayed (refer to Chapter 7 Troubleshoot-
ing).
Parameters which had been stored in the encoder before will be overwritten.

Read Parameters From the Encoder Memory

To read parameters form the encoder memory the parameter F1-25 must be set to 2. Before reading the param-
eters make sure that the correct control mode and encoder type are selected in the parameters A1-02 and N8-
35. If parameter N8-35 has to be changed, cycle the power supply after changing it and set parameter F1-25 to
2 afterwards (ECPY, ENCINV COPYING is displayed during the read process). The display of F1-25
automatically returns to 0 when the operation is finished (ECPY, COPY COMPLETE is displayed). If any
fault occurs the fault code will be displayed (refer to Chapter 7 Troubleshooting).

6 Verify Saved Parameters

To compare the parameters stored in the Inverter and encoder the parameter F1-25 must be set to 3 (EVRFY,
DATA VERIFYING is displayed during the verify process).
If the data are identically, the display will show EVRFY, VERIFY COMPLETE.
If the data do not match, EVRFY, VERIFY ERROR will be displayed.

In order to perform the WRITE/COPY function:

The motor must not turn and the Inverter must be in baseblock condition.
For EnDat the OEM1 area1 of the EEPROM must be available (address 64 to 255).
IMPORTANT For HIPERFACE the data field DF#0 must be available.
A CPF03/CPF24 must not be active.

6 Using PG Speed Control Board

There are two types of PG Speed control board that can be used in closed-loop vector control:
PG-B2: A/B-phase pulse input, compatible with complimentary outputs.
PG-X2: A/B/Z-phase pulse input, compatible with line drivers (RS-422).

PG-F2: EnDat I/f, HIPERFACE R

I/f.
For the mounting instructions, specifications and connection diagrams refer to page 2-26, Installing and Wir-
ing Option Cards.

If open-loop vector control is used and a PG board is installed, the speed detected by the PG board is dis-
played in the monitor parameter U1-05. Therefore the PG parameter has to be set in parameter F1-01. The
direction of the speed detection can be changed by parameter F1-05.
To change the U1-05 value to the internally calculated value remove the PG board.
IMPORTANT

Setting Number of PG Pulses (F1-01)

Set the number of PG (Pulse Generator/Encoder) pulses in pulses per revolution.

6-98
 PG Option Cards

Suit the PG Rotation Direction and Motor Rotation Direction (F1-05)

With the used PG the A-phase leads (CCW) when motor rotation is forward.

Generally, the A-phase leads when the rotation direction is counter-clockwise (CCW) seen from the shaft side
(FWD command is input).

Setting PG Pulse Monitor Output Division Ratio (F1-06)

This function is enabled only when using PG speed control board PG-B2. Set the division ratio for the PG 6
pulse monitor output. The set value is expressed as n for the higher place digit, and m for the two lower place
digits. The dividing ratio is calculated as follows:
Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32

F1-06 = n m

The division ratio can be set within the following range: 1/32 F1-06 1. For example, if the division ratio is
1/2 (set value 2), half of the number of pulses from the PG are output at the pulse monitor.

Detecting PG Open Circuit (F1-02 and F1-14)

Parameter F1-02 selects the stopping method when a PG disconnection is detected.
PG open (PGO) is detected only when the Inverter is running at least with a frequency reference higher than
1% of the maximum output frequency or above the minimum frequency (E1-09) and the PG feedback signal is
missing for the time set in F1-14 or longer.

Detecting Motor Overspeed (F1-03, F1-08 and F1-09)

An overspeed (OS) is detected when the motor speed continues to exceed the set frequency value in F1-08 for
a time longer than set in F1-09. After detecting an overspeed (OS), the Inverter stops according to the setting
in F1-03.

6-99
 Detecting a Speed Deviation between the Motor and Speed Reference (F1-04, F1-10
and F1-11)
A speed deviation fault is detected when the speed deviation (i.e., the difference between the speed reference
and the actual motor speed) is too large. Speed deviation (DEV) is detected only after a speed agreement
(speed reference and actual motor speed are within the setting range of L4-02) and if a speed deviation higher
than the set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected,
the Inverter stops according to the setting in F1-04.

Setting the Absolute Encoder Resolution (F1-21)

If a HIPERFACE encoder is used, the serial line resolution must be selected by parameter F1-21 according to
the encoder data sheet. The possible resolution setting depends on the encoder selection (N8-35=5):
HIPERFACE: 0, 1 or 2 (16384, 32768, 8192)
EnDat: 2 (fixed to 8192)

6-100
 Emergency Operation

Emergency Operation

Using emergency operation the car can be moved to the next floor if the power supply fails. In this case the
Inverter must be supplied by a UPS or a battery and the emergency operation must be enabled by a multi-func-
tion contact input (H1- = 85). The battery voltage has to be set in parameter L2-11. A light load detection
function can be used to detect the light load direction for the car evacuation.
Emergency operation powered by a backup battery requires the use of the PG-F2 option card. The Inverter
cannot run a Permanent magnet motor with the backup battery if any other option card is used.

Emergency Operation Speed

During emergency operation the speed is limited by the battery voltage using the following formula:
for the 200 V class: Battery Voltage L2-11 Base frequency E1-04
Emergency Operation Speed Limit = -------------------------------------------------------------------------------------------------------------------
300 V 2

for the 400 V class: Battery Voltage L2-11 Base frequency E1-04
Emergency Operation Speed Limit = -------------------------------------------------------------------------------------------------------------------
600 V 2 6
If the emergency speed reference (d1-15) is higher than the emergency operation speed limit, the output fre-
quency is automatically limited to the calculated limit. It prevents a voltage saturation and a possible motor
stalling.

Precautions
Because of the possibly low DC bus voltage during battery operation, the heatsink cooling fans may not work.
A continuous operation under this condition can result in over heat faults and Inverter damage.

6-103
 Light Load Direction Detection
The Inverter can detect the light load direction for emergency operation. Therefore, if the light load direction
search is enabled (S3-06 is set to 1), the elevator is driven with the emergency speed in forward direction first
and in reverse direction afterwards. The current/torque is measured in both directions and compared to each
other.
If the detected light direction is forward, the Inverter stops and restarts in the forward direction with the set
emergency operation speed. At the restart the light load detection status output (H2-=45) and the light
load direction output (H1-=44) are set.

Functions
When L5-05 is set its default value of 0, the Inverter will restart itself after a fault occurs as has tradition-
ally done.
If L5-05 is set to 1, then the Inverter will always attempt to restart itself after a UV1 fault, regardless of the

6 value saved to parameter L5-01.

When a fault restart is executed, then fault relays MA-MC and MB-MC will be closed (factory setting). If
the fault restart relay is disabled, then be sure that L5-02 is set to 0 (Auto restart operation selection).
Even when L5-05=1, the Inverter will follow the setting value saved to L5-01, counting faults other than
UV1* and registering that number in the fault restart history. If UV1 and other faults occur intermittently,
all faults other than UV1 will be included in the number of fault restart attempts.
* The Inverter will attempt to restart itself after the following faults occur: OV, GF, OC, OL2, OL3, OL4, UL3, UL4, PF, LF, SE1, SE2, and SE3

 MEMOBUS Communications

MEMOBUS Communications

RS-422/485 Interface
You can perform serial communications with MEMOCON-series Programmable Controllers (PLCs) or simi-
lar devices using the MEMOBUS protocol.

MEMOBUS Communications Configuration

MEMOBUS communications are configured using 1 master (PLC) and a maximum of 31 slaves. Serial com-
munications between master and slave are normally started by the master, and the slave responds.
The master performs signal communications with one slave at a time. Consequently, you must set the address
of each slave beforehand, so the master can perform signal communications using that address. Slaves receiv-
ing commands from the master perform the specified function, and send a response to the master.

Procedure for Communicating with the PLC

Use the following procedure to perform communications with the PLC.
1. Turn OFF the power supply turned and connect the communication cable between the PLC and the
Inverter.
2. Turn ON the power supply.
3. Set the required communications parameters (H5-01 to H5-07) using the Digital Operator.
4. Turn OFF the power supply, and check that the Digital Operator display has completely disappeared.
5. Turn ON the power supply once again.
6. Perform communications with the PLC.

6 Set the timer on the master to monitor response time from the slave. Set the master so that if the slave
does not respond to the master within the set time, the same command message will be sent from the
master again.

 MEMOBUS Communications

Error Check
Errors are detected during communications using CRC-16. Perform calculations using the following method.
1. The factory setting for CRC-16 communications is usually 0, but when using the MEMOBUS system, set
the factory setting to 1 (i.e., set all 16 bits to 1).
2. Calculate CRC-16 using MSB as slave address LSB, and LSB as the MSB of the final data.
3. Also calculate CRC-16 for response messages from the slaves, and compare them to the CRC-16 in the
response messages.

MEMOBUS Message Example

An example of MEMOBUS command/response messages is given below.

Reading Storage Register Contents

Read the contents of the storage register only for specified quantities whose addresses are consecutive, starting
from a specified address. The contents of the storage register are separated into higher place 8 bits and lower
place 8 bits, and comprise the data within response messages in address order.

ENTER Command
When writing parameters to the Inverter from the PLC using MEMOBUS communications, the parameters are
temporarily stored in the parameter data area in the Inverter. To enable these parameters in the parameter data
area, use the ENTER command.
There are two types of ENTER commands: ENTER commands that enable parameter data in RAM, and
ENTER commands that write data to EEPROM (non-volatile memory) in the Inverter at the same time as
enabling data in RAM.
The following table shows the ENTER command data. ENTER command data can only be written.
The ENTER command is enabled by writing 0 to register number 0900H or 0901H.
Register No. Contents
0900H Write parameter data to EEPROM
0910H Parameter data is not written to EEPROM, but refreshed in RAM only.

 MEMOBUS Communications

The maximum number of times you can write to EEPROM using the Inverter is 100 thousand. Do not fre-
quently execute ENTER commands (0900H) written to EEPROM.
The ENTER command registers are write-only. Consequently, if reading these registers, the register
INFO address will become invalid (Error code: 02H).

Error Codes
The following table shows MEMOBUS communications error codes.
Error Code Contents
Function code error
01H
A function code other than 03H, 08H, or 10H has been set by the PLC.
Invalid register number error
02H The register address you are attempting to access is not recorded anywhere.
With broadcast sending, a start address other than 0000H, 0001H, or 0002H has been set.
Invalid quantity error

24H
Attempting to write parameters from the PLC while processing parameters in the Inverter.

Slave Not Responding

In the following cases, the slave will ignore the write function. If the slave address specified in the command
message is 0, all slaves execute the write function, but do not return response messages to the master.
When a communications error (overrun, framing, parity, or CRC-16) is detected in the command message.
When the slave address in the command message and the slave address in the Inverter do not agree.
When the data that configures the message and the data time length exceeds 24 bits.
When the command message data length is invalid.

Application Precautions
Set a timer in the master to monitor response time from the slaves. Make the setting so that if no response is
sent to the master from the slave within the set time, the same command message is sent again from the mas-
ter.

 Self-Diagnosis
The Inverter has a built-in function for self-diagnosing the operations of serial communications interface cir-
cuits. This function is called the self-diagnosis function. The self-diagnosis function connects the communica-
tions parts of the send and receive terminals, receives the data sent by the Inverter, and checks if
communications are being performed normally.
Perform the self-diagnosis function using the following procedure.
1. Turn ON the power supply to the Inverter, and set 67 (communications test mode) in parameter H1-05
(Terminal S7 Function Selection).
2. Turn OFF the power supply to the Inverter.
3. Perform wiring according to the following diagram while the power supply is turned OFF.
4. Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)
5. Turn ON the power supply to the Inverter again.

Pass will be displayed if self-diagnosis is completed without an error occurring.

If an error occurs, a CE (MEMOBUS communications error) alarm will be displayed on the Digital Operator,
the error contact output will be turned ON, and the Inverter operation ready signal will be turned OFF.

 Protective and Diagnostic Functions

This section describes the fault and alarm functions of the Inverter. These functions include fault detection,
alarm detection, programming error detection and auto-tuning error detection.

Fault Detection
When the Inverter detects a fault, the fault contact output is operated and the Inverter output is switched OFF
and the motor coasts to stop. (The stopping method can be selected for some faults.) A fault code is displayed
on the Digital Operator/LED Monitor.
The faults can be categorized in two groups:
Faults that can be reset without cycling the power using an input or the reset key at the Digital Operator
(resetable faults)
Faults that require to cycle the power (non-resetable faults)
When a fault has occurred refer to the following to identify the fault and to correct the causes.
To reset a fault it is necessary to remove the RUN signal and correct the fault reason. Otherwise a Reset is not
accepted or the Inverter trips with the same fault again.
The following tables shows a list of faults and corrective actions.

Alarm Detection
Alarms are Inverter protection functions that indicate unusual conditions without switching off the inverter
and operating the fault output contact. The alarm automatically disappears when its cause is eliminated.
During an alarm condition, the Digital Operator/LED Monitor alarm display flashes and an alarm output is
generated at the multi-function outputs (H2-01 to H2-03) if programmed.
When an alarm occurs, take appropriate countermeasures according to the table below.

 Troubleshooting

Troubleshooting

Due to parameter setting errors, faulty wiring etc., the Inverter and motor may not operate as expected when
the system is started. If that occurs, use this section as a reference and perform the appropriate countermea-
sures.
If a fault code is displayed, refer to page 7-2, Protective and Diagnostic Functions.

If A Parameter Cannot Be Set

Use the following information if a parameter cannot be set.

The display does not change when the Increment and Decrement keys are pressed.
The following causes are possible:

The Inverter is operating (Drive mode).

There are some parameters that cannot be set during operation. Turn off the Run Command and then set the
parameters.

Passwords do not match. (Only when a password is set.)

If the parameter A1-04 (Password) and A1-05 (Password Setting) settings are different, the parameters for the
initialize mode cannot be changed. Enter the correct password in A1-04.
If you cannot remember the password, check parameter A1-05 (Password Setting) by pressing the Shift/
RESET key and the MENU key simultaneously in the A1-04 display. Read the password and set it in parame-
ter A1-04.

OPE01 through OPE11 is displayed.

The set value for the parameter is wrong. Refer to Table 7.4 in this chapter and correct the settings.

CPF00 or CPF01 is displayed.

This is a Digital Operator/LED Monitor communication error. The connection between the Digital Operator/ 7
LED Monitor and the Inverter may be faulty. Remove the Digital Operator/LED Monitor and then re-install it.

7-17
 If the Motor Does Not Operate Properly
The following causes are possible:

The motor does not operate when an external operation signal is input.
The frequency reference is 0.00 Hz or a no speed is selected by the multi-function contact inputs. Check the
input signals and the frequency reference settings.
Also make sure to set the Baseblock signal. The Inverter does not accept any input if it is baseblocked.

The load is too heavy

Check the motor current. If it is at the limit of the Inverter rated current the load might be too high. Check the
Inverter size and the mechanical system. Check also if the brake is working or not to make sure, that the motor
is not running against the closed brake.

If the Direction of the Motor Rotation is Reversed

If the motor rotates in the wrong direction, the motor output wiring may be incorrect.
The direction of the motor rotation can be reversed by switching two wires among U, V, and W. If an encoder
is used, the polarity has to be switched over as well. If the Inverter is operated in V/f mode parameter b1-04
can be used to change the rotation direction.

If the Motor Stalls or Acceleration is Slow

The torque limit has been reached.

When a torque limit has been set in parameters L7-01 to L7-04, the output torque will be limited according to
these settings. Therefore the motor may not develop enough torque to accelerate or the acceleration time might
7 be very long.

The stall prevention level during acceleration is too low.

If the value set in L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be
increased. Check that the set value is suitable and that the load is not too large for the motor.

The stall prevention level during running is too low.

If the value set in L3-06 (Stall Prevention Level during Running) is too low, the motor speed and torque will
be limited. Check that the set value is suitable and that the load is not too large for the motor.

Autotuning has not been performed for vector control

Vector control does not work properly, if autotuning has not been performed. Perform autotuning, or set the
motor parameters manually.

7-18
 Troubleshooting

If Motor Deceleration is Slow

The following causes are possible:

The deceleration time is too long

The following causes are possible:

The deceleration time setting is too long.

Check the deceleration time setting (parameters C1-02, C1-04, C1-06, and C1-08).

Motor torque is insufficient.

If the parameters are correct and there is no overvoltage fault, then the motor's power may be insufficient.
Consider increasing the motor and Inverter capacity.

The torque limit has been reached.

When a torque limit is reached (L7-01 to L7-04), the motor torque will be limited. This can lengthen the decel-
eration time. Check the L7- parameters to be sure that the torque limit values are suitable.

If the Motor Overheats

The following causes are possible:

The load is too large.

If the motor load is too large and the torque exceeds the motors rated torque, the motor may overheat. Either
reduce the load or increase the acceleration/deceleration times. Also consider increasing the motor size.

The ambient temperature is too high.

7
The motor rating is determined by a particular ambient operating temperature range. The motor will overheat
if it is run continuously at the rated torque in an environment where the maximum ambient operating tempera-
ture is exceeded. Lower the motor's ambient temperature to an acceptable value.

Autotuning has not been performed for vector control

The Vector control performance may not be optimal, if autotuning has not been performed. Perform autotun-
ing, or set the motor parameters manually. Alternatively, change the Control Method Selection (A1-02) to V/f
Control (0 or 1).

7-19
 If Peripheral Devices are Influenced by the Starting or Running Inverter
The following solutions are possible:
Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency. This will help to
reduce the amount of transistor switching noise.
Install an Input Noise Filter at the Inverter's input power terminals.
Install an Output Noise Filter at the Inverter's motor terminals.
Use shielded motor cables or a conduit. Metal shields electrical noise.
Check the grounding of the Inverter and motor.
Separate main circuit wires from control circuit wires.

If the Earth Leakage Breaker Operates When the Inverter is Running

The Inverters output is pulse modulated, i.e. the output voltage consists of high frequency pulses (PWM).
This high frequency signal causes a certain amount of leakage current which may cause the earth leakage
breaker to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage
detection level (i.e., a sensitivity current of 200 mA or higher, with an operating time of 0.1 s or more), and
one, which incorporates high frequencies countermeasures (i.e., one designed for use with Inverters). Lower-
ing the Inverter's Carrier Frequency Selection (C6-02) can also help, since the leakage current increases with
the cable length.

If There is Mechanical Oscillation

Use the following information when there is mechanical vibration:

Oscillation and hunting occur with V/f control

7 The torque compensation parameter settings may be incorrect for the machine. Adjust parameters C4-01
(Torque Compensation Gain) and C4-02 (Torque Compensation Delay Time). Decrease C4-01 carefully in
steps of 0.05 and/or increase C4-02.
Furthermore the Slip Compensation Delay Time (C3-02) can be increased or decreased.

Oscillation and hunting occur with open-loop vector control.

The torque compensation parameter settings may be incorrect for the machine. Adjust parameters C4-01
(Torque Compensation Gain), C4-02 (Torque Compensation Delay Time Parameter) and C3-02 (Slip Com-
pensation Delay Time) in order. Lower the gain parameters and raise the delay time parameters.
If autotuning has not been performed, proper performance may not be achieved for Vector Control. Perform
autotuning or set the motor parameters manually.

Oscillation and hunting occur with closed-loop vector control

The gain adjustment may be insufficient. Adjust the speed control loop (Automatic Speed Regulator, ASR) by
changing the C5- parameters. If the oscillation points overlap with those of the machine and cannot be
eliminated, increase the ASR Delay Time, and then readjust the ASR gains.
If autotuning has not been performed, proper performance may not be achieved for closed-loop vector control.
Perform autotuning or set the motor parameters manually.

Maintenance and
Inspection
This chapter describes basic maintenance and inspection for the Inverter.

Maintenance and Inspection ...............................................8-2

 Maintenance and Inspection

Periodic Inspection
Check the following items during periodic maintenance.
The motor should not vibrate or make unusual noises.
There should be no abnormal heat generation from the Inverter or motor.
The ambient temperature should be within the Inverters specifications.
The output current value shown in U1-03 should not be higher than the motor or the Inverter rated current
for extended period of time.
The cooling fan in the Inverter should be operating normally.

Before attempting any maintenance checks, make sure that the three-phase power is disconnected. With power
removed from the unit, the DC bus capacitors will stay charged for several minutes. The charge LED in the
Inverter will light red until the DC bus voltage is below 10VDC. To ensure that the DC bus is completely dis-
charged, measure between the positive and negative bus with a DC voltmeter. Be sure not to touch terminals
immediately after the power has been turned off. Doing so can result in electric shock.

Cooling fans used for the Inverter has two types; Heatsink cooling fan and heatsink circulation fan. Heatsink
cooling fan blows air to the Inverter cooling fin. Heatsink circulation fan stirs up the air inside the Inverter
unit.
Table 8.2 shows the number of cooling fans used in the Inverter. For more information on models and specifi-
cations of cooling fans, contact your Yaskawa representative or YASKAWA ELECTRIC ENGINEERING
CORPORATION.
When replacing the fan, use the specified type of the fan. If the inapplicable fans are used, performance of the
Inverter will not be fully obtained.

 Inverter Application Precautions

Selection
Observe the following precautions when selecting an Inverter.

Installing Reactors
A large peak current can flow in the power input circuit when the Inverter is connected to a large-capacity
power transformer (600 kVA or higher) or when switching a phase shifting capacitor. Excessive peak current
can destroy the converter section. To prevent this, install a DC or AC reactor to improve the power supply
power factor.
If a thyristor converter, such as a DC inverter, is connected in the same power supply system, connect a DC or
AC reactor regardless of the power supply conditions shown in the following diagram.

DC or AC reactor
Power supply
required
(kVA)
DC or AC reactor not
required

Inverter capacity (kVA)

Installation
Observe the following precautions when installing an Inverter.

Installation in Enclosures
Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, or
install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that
the temperature surrounding the Inverter does not exceed the allowable temperature. Do not install the Inverter
on wood or other combustible materials.

Installation Direction
Mount the Inverter vertically to a wall or other vertical surface.

Settings
Observe the following precautions when making settings for an Inverter.

10 Upper Limits
The maximum output frequency can be set up to 120Hz. Setting the output frequency too high can damage the
machine. So pay attention to the mechanical system and observe required limits for the output frequency.

DC Injection Braking
If the DC Injection Braking Current or the Braking Time are set too high the motor can overheat what can
damage the motor

10-2
 Inverter Application Precautions

Acceleration/Deceleration Times
The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load
torque, and the load's inertial moment (GD2/4). If the stall prevention functions are activated during accelera-
tion or deceleration, it might be necessary to increase the acceleration or deceleration time.
To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.

Handling
Observe the following precautions during wiring or maintenance of an Inverter.

Wiring Check
The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.
Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully.

Magnetic Contactor Installation

If a magnetic contactor is installed in the power supply line, do not exceed one start per hour. Switching more
often can damage the inrush current prevention circuit.

Maintenance and Inspections

After turning OFF the main circuit power supply it can take several minutes before the DC bus is discharged
completely. The CHARGE LED, indicating if the DC bus is charged, glows above a voltage of 10VDC.

10

10-3
 Motor Application Precautions

Using the Inverter for an Existing Standard Motor

Observe the following precautions when using an Inverter for an existing standard motor.

Low Speed Ranges

If a standard cooled motor is used at low speed the cooling effects are diminished. If the motor is used in
parameter torque applications in low speed area the motor may overheat. If full torque is required at low speed
continuously an externally cooled motor must be used.

Installation Withstand Voltage

If the Inverter is used with an input voltage of 440 V or higher and long motor cables, voltage spikes at the
motor terminals may occur which can damage the motor windings. Please ensure that the motor insulation
class is sufficient.

Noise
The noise generated in the motor depends on the carrier frequency. The higher the setting, the less is the gen-
erated noise.

Using the Inverter for Special Motors

Observe the following precautions when using a special motor.

Pole-changing Motor
The rated input current of pole-changing motors differs from that of standard motors. Select an appropriate
Inverter according to the maximum current of the motor.

Single-phase Motor
Do not use an Inverter for a single-phase motor. These motors are often equipped with capacitors Any capaci-
tor directly connected to the Inverter output may damage the Inverter.

Gearmotor
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
In particular, continuous operation of an oil-lubricated motor in the low speed range may result in burning. If
the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer.

Power Transmission Mechanism (Speed Reducers, Belts, and Chains)

10 If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will
be affected when the motor operates only in the low speed range. The power transmission mechanism will
make noise and experience problems with service life and durability if the motor is operated at a speed higher
than the rated speed.

 EMC Compatibility

EMC Compatibility
Introduction
This manual was compiled to help system manufacturers using Yaskawa frequency Inverters to design and
install electrical switch gear. It also describes the measures necessary to comply with the EMC Directive. The
manual's installation and wiring instructions must therefore be followed.
Our products are tested by authorized bodies using the standards listed below.
Product standard: EN 61800-3:1996
EN 61800-3; A11:2000

Measures to Ensure Conformity of Yaskawa Inverters to the EMC Directive

Yaskawa frequency Inverters do not necessarily have to be installed in a switch cabinet.
It is not possible to give detailed instructions for all of the possible types of installation. This manual therefore
has to be limited to general guidelines.
All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass
this on to the environment like an aerial.
Connecting an item of electrical equipment (e.g. inverter) to a supply without a line filter can therefore allow
HF or LF interference to get into the mains.
The basic countermeasures are isolation of the wiring of control and power components, proper grounding and
shielding of cables.
A large contact area is necessary for low-impedance grounding of HF interference. The use of grounding
straps instead of cables is therefore definitely advisable.
Moreover, cable shields must be connected with purpose-made ground clips.

Laying Cables
Measures Against Line-Borne Interference:
Line filter and frequency Inverter must be mounted on the same metal plate. Mount the two components as
close to each other as possible, with cables kept as short as possible.
Use a power cable with well-grounded shield. Use a shielded motor cable not exceeding 20 meters in length.
Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (e.g.
metal plate).
Shielded Cable:
Use a cable with braided shield.
Ground the maximum possible area of the shield. It is advisable to ground the shield by connecting the cable
to the ground plate with metal clips (see following figure).

10

10-5
 Ground clip Ground plate

The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and paint.
Ground the cable shields at both ends.
Ground the motor of the machine.
