1.4 Wiring between Inverter and Peripheral devices and notice

Caution

1. After turning OFF the main circuit power supply, do not touch the circuit
components or change any circuit components before the “CHARGE” lamps
extinguished. (It indicates that there is still some charge in the capacitor).
2. Never do wiring work or take apart the connectors in the inverter while the power
is still on.
3. Never connect the inverter output U/T1, V/T2, W/T3 to the AC source.
4. Always connect the ground lead E to ground.
5. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock.)
6. The CMOS IC on the control board is vulnerable to ESD. Do not try to touch the
control board.
7. If Sn-03 is 7,9,11 (2-wire mode) or is 8,10,12 (3-wire mode), except parameter
settings of Sn-01 and Sn-02, the other parameter settings will return to their initial
settings at factory. If the inverter is initially operated in 3-wire mode (Sn-03=
8,10,12), the motor will rotate in CCW sense after setting changed to 2-wire mode.
(Sn-03= 7,9,11). Be sure that the terminals 1 and 2 are OPEN so as not to harmful
to personal or cause any potential damage to machines.

Caution

1.Determine the wire size for the main circuit so that the line voltage drop is within
2% of the rated voltage. If there is the possibility of excessive voltage drop due to
wire length, use a larger wire (larger diameter) suitable to the required length
Line voltage drop(V) = 3 × wire resistance(Ω/km) × wire length(m) × current(A) × 10 -3
2.If the length of the cable wire between the inverter and the motor exceeds 30m, use
a lower carrier frequency for PWM (adjust the parameter Cn-34). Refer to Page 56.

Example of connection between the 7200MA and typical peripheral devices are
shown as below.
Power supply ■Power supply switch(NFB) and earth leakage breaker
．Choose the power supply switch(NFB) of proper current
rating.
Power supply ．Do not use the power supply switch(NFB) as the switch
switch(NFB) that the inverter is used to control the running or stop of
and earth motor.
leakage ．When the earth leakage breaker installed to protect the
breaker
leakage current fault, be sure that the earth leakage breaker
has the sensitivity amperage≧200mA per inverter and
operation time ≧0.1 sec to avoid false-triggering.
■ Electromagnetic contactor
．In normal operation, you don’t need an electromagnetic
Electromagnetic contactor. However, you need to install an electro-
contactor magnetic contactor while in the case of sequence control
through the external device or automatically re-start after
power outage.
．Do not use the electromagnetic contactor as the switch that
control the operation of running or stop.
AC reactor ■ AC reactor
．The AC-side reactor on the input AC side can improve the
power factor and suppress the surge current.

■ Input noise filter

Input noise ．7200MA will comply with the EN55011 class A regulation if
filter an input noise filter (specified by TECO) is used.
．Please refer to the selection guide “1.9 Peripheral device”
on page 24.

■ 7200MA inverter
7200MA ．Input power supply can be connected to any terminal
inverter R/L1, S/L2, T/L3 on the terminal block. The phase
sequence of input power supply is irrelevant to phase
sequence.
．Please connect the ground terminal E to the site ground
securely.
Zero phase
■ Zero phase core
core ．Install the zero phase corer to eliminate noise transmitted
between the power line and the inverter.
．Please refer to the selection guide “1.9 Peripheral device”
on page 25
.
■ Induction Motor
Induction ．If one inverter is to drive more than one motors, the
motor
inverter’s rated current should be much greater than the
sum of total current of motors while in operation.
．The inverter and the motor should connect to the ground
separately.

*1 : It is assumed constant torque load.

*2 : The main circuit has terminals of R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, B1/P,
B2/R, B2,Θ.
*3 : The control wire is the wire led to the pin terminals of control board.
*4 : In Table 3, the specified Part No. of NFB and MC are the item No. of the
products of Taian. The customer can use the same rating of similar products
from other sources. To decrease the noise interference, be sure to add R-C
surge suppressor (R: 10Ω/5W, C: 0.1µF/1000VDC) at the 2 terminals of coils
of electromagnetic contactor.
15
■ External circuit wiring precaution:
(A) Control circuit wiring:
(1) Separate the control circuit wiring from main circuit wiring (R/L1, S/L2, T/L3,
U/T1, V/T2, W/T3) and other high-power lines to avoid noise interruption.
(2) Separate the wiring for control circuit terminals RA-RB-RC (R1A-R2B-R2C)
(contact output) from wiring for terminals c∼j, A01, A02, GND, DO1, DO2
(R2A-R2C), DOG and 15V, VIN, AIN, AUX, GND, IP12, IG12, A (+), A (-).
(3) Use the twisted-pair or shielded twisted-pair cables for control circuits to prevent
operating faults. Process the cable ends as shown in Fig. 3. The max. wiring
distance should not exceed 50 meter.

When the digital multi-function output terminals connect serially to an external
relay, an anti-parallel freewheeling diode should be applied at both ends of relay, as
shown below.
50 mA max. 48V max.

7200MA external wiring circuit

Fig. 4 The Optical-couplers connect to external inductive load

(B) Wiring the main circuit terminals:
(1) Input power supply can be connected to any terminal R/L1, S/L2 or T/L3 on the
terminal block. The phase sequence of input power supply is irrelevant to the
phase sequence.
(2) Never connect the AC power source to the output terminals U/T1, V/T2 and. W/T3.
(3) Connect the output terminals U/T1, V/T2, W/T3 to motor lead wires U/T1, V/T2,
and W/T3, respectively.
(4) Check that the motor rotates forward with the forward run source. Switch over
any 2 of the output terminals to each other and reconnect if the motor rotates in
reverse with the forward run source.
(5) Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit.

16
(C) GROUNDING：
(1) Always use the ground terminal (E) with a ground resistance of less than
100Ω.
(2) Do not share the ground wire with other devices, such as welding machines or
power tools.
(3) Always use a ground wire that complies with the technical standards on
electrical equipment and minimize the length of ground wire.
(4) When using more than one inverter, be careful not to loop the ground wire, as
shown below.

(a) OK (b) OK (c) NO

Fig. 5 7200MA ground winding

•Determine the wire size for the main circuit so that the line voltage drop is within
2% of the rated voltage. (If there is the possibility of excessive voltage drop, use a
larger wire suitable to the required length)

• Installing an AC reactor
If the inverter is connected to a large-capacity power source (600kVA or more),
install an optional AC reactor on the input side of the inverter. This also improves
the power factor on the power supply side.

•If the cable between the inverter and the motor is long, the high-frequency leakage
current will increase, causing the inverter output current to increase as well. This
may affect peripheral devices. To prevent this, adjust the carrier frequency, as
shown below:

Cable length < 30m 30m ~50m 50m ~100m ≧100m

Carrier frequency 15kHz max 10kHz max 5kHz max 2.5kHz

•Model : JUNFOC046S －－－－－－－
•Code No. : 4H000D0250001
•According to the required power rating and wire size, select the matched ferrite
core to suppress EMI noise.
•The ferrite core can attenuate the frequency response at high frequency range
(from 100KHz to 50MHz, as shown below). It should be able to attenuate the
RFI from inverter to outside.
•The zero-sequence noise ferrite core can be installed either on the input side or
on the output side. The wire around the core for each phase should be winded by
following the same convention and one direction. The more winding turns the
better attenuation effect. (Without saturation). If the wire size is too big to be
winded, all the wire can be grouped and go through these several cores together
in one direction.

2. Using LCD Digital Operator
■ Functions of LCD digital operator
JNEP-31 LCD digital operator has 2 modes: DRIVE mode and PRGM mode.
When the inverter is stopped, DRIVE mode or PRGM mode can be selected by
PRGM
pressing the key DRIVE . In DRIVE mode, the operation is enabled. Instead, in
the PRGM mode, the parameter settings for operation can be changed but the
operation is not enabled. The component names and function are shown as below:

operation mode indicators

■ Parameter description
The 7200MA has 4 groups of user parameters:

Parameters Description
An-□□ Frequency command
Bn-□□ Parameter groups can be changed during running
Sn-□□ System parameter groups (can be changes only after stop)
Cn-□□ Control parameter groups (can be changed only after stop)

The parameter setting of Sn-03 (operation status) will determine if the setting
value of different parameter groups are allowed to be changed or only to be
monitored, as shown below:

DRIVE mode PRGM mode

Sn-03
To be set To be monitored To be set To be monitored
0*1 An,Bn Sn,Cn An,Bn,Sn,Cn －

1 An Bn,(Sn,Cn) *2 An Bn,Sn,Cn

*1：Factory setting
*2：When in DRIVE mode, the parameter group Sn-, Cn- can only be monitored if
the RESET key and the DSPL key are to be pressed simultaneously.

After a few trial and adjustment, the setting value Sn-03 is set to be “1” so as not
be modified again.

■ Example of using LCD digital operator

Note：
Before operation: Control parameter Cn-01 value must be set as the
input AC voltage value. For example, Cn-01=380 if
AC input voltage is 380.

This example will explain the operating of 7200MA according to the following time

(11) Auto Torque Boost Gain (Bn-11)

•The inverter can increase the output torque to compensate the load increase
automatically through the auto torque boost function. Then the output voltage will
increase. As a result, the fault trip cases can be decreased. The energy efficiency is
also improved. In the case that the wiring distance between the inverter and the
motor is too long (e.g. more than 100m), the motor torque is a little short because
of voltage drop. Increase the value of Bn-11 gradually and make sure the current
will not increase too much. Normally, no adjustment is required.

(22) Timer ON_Delay Time (Bn-37)

•The timer function is enabled when the timer function input setting (Sn-25~28=19)
and its timer function output setting (Sn-30~32=21) are set for the multi-function
input and output respectively.
•These inputs and outputs serve as general-purpose I/O . Setting ON/OFF delay
time (Bn-37/38) for the timer can prevent chattering of sensors, switches and so on.
•When the timer function input ON times is longer than the value set for Bn-37, the
timer function output turns ON.
•When the timer function input OFF time is longer than the value set for Bn-38, the
timer function output turns OFF. An example is shown below.

(24) Energy_Saving Gain (Bn-39)
•Input the energy_saving command while a light load causes the inverter output
voltage to be reduced and save energy. Set this value as a percentage of the V/F
pattern. The setting range is 50~150%. The factory setting is 100% and the energy
saving function is disabled. If the energy saving gain Bn-39 is not 100%, the
energy saving function is enabled.
•In energy saving mode (Bn-39≠100), the output voltage will automatically
decrease and be proportional to energy saving gain Bn-39. The Bn-39 setting
should not be small so that the motor will not stall.
•The energy saving function is disabled in the PID close-loop control and during
acceleration and deceleration.

(1) Input Voltage Setting (Cn-01)
•Set inverter voltage to match power supply voltage at input side (e.g.：200V/220V,
380V/415V/440V/460V)
(2) V/F Curve Parameter Settings (Cn-02∼Cn-08)
•The V/F curve can be set to either one of the preset curves (setting Sn-02=0∼14)
or a customer user-set curve (setting Sn-02=15).
•Setting Cn-02∼Cn-08 can be set by the user when Sn-02 has been set to “15”. The
user-defined V/F curve can be specified through the settings of Cn-02∼Cn-08 as
shown in Fig. 18. The factory setting is straight line for the V/F curve. (Cn-05=Cn-
07, Cn-06 is not used) as shown below (220V/60Hz case).

•In low speed operation (<3Hz), a larger torque can be generated by increasing the
slope of V/F curve. However, the motor will be hot due to over-excitation. At the
same time the inverter will be more inclined to fault. Based upon the applied load,
properly adjust the V/F curve according to the magnitude of monitored current into
the motor.
•The four frequency settings must satisfy the following relationship, otherwise an
error message “V/F Curve Invalid” will display.
(a) Max. output freq.≧ Max. voltage freq. ＞ Mid. Output freq. ≧ Min. output freq.
(Cn-02) (Cn-04) (Cn-05) (Cn-07)
(b) Max. output volt.≧ Mid. output volt. ＞ Min. output voltage
(Cn-03) (Cn-06) (Cn-08)
•If Mid. Output frequency (Cn-05) = Min. output frequency (Cn-07), the setting
(Cn-06) is not effective.
(3) Motor Rated Current (Cn-09)
•Electronic overload thermal reference current
•The factory setting depends upon the capacity type of inverter (Sn-01).
•The setting range is 10%∼200% of the inverter rated output current.
•Set the rated current shown on the motor nameplate if not using the TECO 4-pole motor.

47
(4) Motor No-Load Current (Cn-10)
•This setting is used as a reference value for torque compensation function.
•The setting range is 0∼99％ of the inverter rated current Cn-09 (100%).
•The slip compensation is enabled when the output current is greater than motor no-
load current (Cn-10). The output frequency will shift from f1 to f2 (>f1) for the
positive change of load torque. (See Fig. 19)

•This setting is used as a reference value for torque compensation function. See Fig.

04) as 100%.
•The setting is shown in Fig. 20 in the constant torque and constant output range. If
setting Cn-11 is zero, no slip compensation is used.
•There is no slip compensation in the cases when the frequency command is less
than the Min. output frequency or during regeneration.

•It is for torque compensation function. The default setting depends upon the
inverter capacity (Sn-01). Normally, the setting does not need to be altered. See
Table 10~11 on page 69.

(8) DC Injection Braking Starting Frequency (Cn-14)

(9) DC Injection Braking Current (Cn-15)
(10)DC Injection Braking Time at Stop (Cn-16)
(11)DC Injection Braking Time at Start (Cn-17)
•The DC injection braking function decelerates by applying a DC current to the
motor. This happens in the 2 cases:
a. DC injection braking time at start: It is effective for temporarily stopping and
then restarting, without regeneration, a motor coasting by inertia.
b. DC injection braking time at stop: It is used to prevent coasting by inertia when
the motor is not completely stopped by normal deceleration when there is a
large load. Lengthening the DC injection braking time (Cn-16) or increasing the
DC injection braking current (Cn-15) can shorten the stopping time.
•For the DC injection braking current (Cn-15), set the value for the current that is
output at the time of DC injection braking. DC injection braking current is set as a
percentage of inverter rated output current, with the inverter rated output current
taken as 100%.
•For the DC injection braking time at start (Cn-17), set the DC injection braking
operating time when the motor is started.
•For the DC injection braking starting frequency (Cn-14), set the frequency for
beginning DC injection braking for deceleration. If the excitation level is less than
the Min. output frequency (Cn-07), the DC injection braking will begin from Min.
output frequency.
•If the DC injection braking time at start (Cn-17) is 0.0, the motor starts from the
Min. output frequency and no DC injection braking are enabled.
•If the DC injection braking time at stop (Cn-16) is 0.0, no DC injection braking is
enabled. In this case, the inverter output will be blocked off when the output
frequency is less than the DC injection braking at start frequency (Cn-14).

(12) Frequency Command Upper Bound (Cn-18)

(13) Frequency Command Lower Bound (Cn-19)
•The upper and lower bounds of the frequency command are set as a percentage of
the Max. output frequency (Cn-02 as 100%), in increments of 1%.
•The relationship Cn-18 > Cn-19 must be abided by. If not, an error message “Freq.
Limit Setting Error” may occur.
•When the frequency command is zero and a run command is input, the motor
operates at the frequency command lower bound (Cn-19). The motor will not
operate, however, if the lower limit is set lower than the Min. output frequency
(Cn-07).

•Operation is prohibited within the jump frequency range, but changes during
acceleration and deceleration are smooth with no jump. To disable this function,
set the jump frequency 1∼3 (Cn-20∼Cn-22) to 0.0Hz.
•For the jump frequency 1∼3 (Cn-20∼Cn-22), set the center frequency to be jumped.
•Be sure to set the jump so that Cn-20 ≥ Cn-21 ≥ Cn-22. If not, a message “Jump
frequency setting error” is displayed. For Cn-23, set the jump frequency
bandwidth. If Cn-23 is set as 0.0Hz, the jump frequency function is disabled.

(18) Number of Auto Restart Attempt (Cn-24)

•The fault restart function will restart the inverter even when an internal fault
occurs during inverter operation. Use this function only when continuing operation
is more important than possibly damaging the inverter.
•The fault restart function is effective with the following faults. With other faults,
the protective operations will engage immediately without attempting to restart
operation.
•Over-current •Ground fault •Main circuit over-voltage
•The fault restart count will automatically increase upon the restart activated and
will be cleared in the following cases:
a. When the operation is normal for 10 minutes after a fault restart is performed.
b. When the fault-reset input is received after the protection operation has been
activated and the fault confirmed. (e.g., by pressing RESET or enable Fault reset
terminal e)
c. When the power is turned off and on again.
•When one of the multi-function output terminals (RA-RB-RC or R1A-R1B-R1C,
DO1, DO2 or R2A-R2C) is set to restart enabled, the output will be ON while the
fault restart function is in progress. See page 90 for the setting of (Sn-30~Sn-32).

(19) Stall Prevention Level During Acceleration (Cn-25)
(20) Stall Prevention Level During Running (Cn-26)
•A stall occurs if the rotor can not keep up with the rotating electromagnetic field in
the motor stator side when a large load is applied or a sudden acceleration or
deceleration is performed. In this case, the inverter should automatically adjust the
output frequency to prevent stall.
•The stall prevention function can be set independently for accelerating and
running.
•Stall Prevention During Acceleration : See Fig. 24. Stop acceleration if Cn-25
setting is exceeded. Accelerate again when the current recovers.
•Stall Prevention During running : See Fig. 25. Deceleration is started if the run
stall prevention level Cn-26 is exceeded, especially when an impact load is applied
suddenly. Accelerate again when the current level is lower than Cn-26.

(26)Overtorque Detection Level (Cn-32)
(27)Overtorque Detection Time (Cn-33)
•The Overtorque detection function detects the excessive mechanical load from an
increase of output current. When an overtorque detection is enabled through the
setting Sn-12, be sure to set Overtorque Detection Level (Cn-32) and Overtorque
Detection Time (Cn-33). An overtorque condition is detected when the output
current exceeds the Overtorque Detection Level (Cn-32) for longer than the
Overtorque Detection Time (Cn-33). The multi-function output terminals (control
circuit terminals RA-RB-RC or R1A-R1B-R1C, DO1, DO2 or R2A-R2C) can be
set to indicate an overtorque condition has been detected.

b. enable only during frequency agreement. Stop operation after detection.
c. enable at anytime. Continue operation even after detection.
d. enable at anytime. Stop operation after detection.
•See more details on page 76

(28)Carrier Frequency Setting (Cn-34)

•Lower the carrier frequency can decrease the noise interference and leakage
current. Its setting is shown below.
Carrier frequency(kHz) = 2.5kHz* Cn-34 setting

Cn-34 = 1 2 3 4 5 6* *factory setting

(2.5 kHz) (15 kHz)

(louder) (insensible)

55
•The output frequency does not need to be adjusted, except in the following cases.
a. If the wiring distance between the inverter and motor is long, lower the carrier
frequency as shown below to allow less leakage current.
Wiring distance <30m 30m~50m 50m~100m >100m
Carrier frequency (Cn-34) <15kHz <10kHz <5KHz <2.5KHz

b. If there is great irregularity in speed or torque, lower the carrier frequency.

(29) Speed Search Detection Level (Cn-35)

(30) Speed Search Time (Cn-36)
(31) Min. Baseblock Time (Cn-37)
(32) Speed Search V/F Curve (Cn-38)
•The speed search function will search the speed of a frequency coasting motor
from the frequency command or max. frequency downward. And it will restart up
smoothly from that frequency or max. frequency. It is effective in situations such
as switching from a commercial power supply to an inverter without tripping
occurred.
•The timing of speed search function as shown below：

Fig. 27 Speed search timing chart

56
•The speed search command can be set through the multi-function contact input
terminal g ~ j (By setting the parameters Sn-25 ~ Sn-28).
If Sn-25 ~ Sn-28= 21 : Speed search is performed from Max. output frequency
and motor is coasting freely.
If Sn-25 ~ Sn-28= 22 : Speed search starts from the frequency command when
the speed search command is enabled.
•After the inverter output is blocked, the user should input speed search command
then enable run operation, the inverter will begin to search the motor speed after
the min. baseblock time Cn-37.
•Speed search operation, if the inverter output current is less than Cn-35, the
inverter will take the output frequency as the real frequency at that time. From
those values of real frequency, the inverter will accelerate or decelerate to the set
frequency according to the acceleration or deceleration time.
•While the speed search command is being performed, the user can slightly
decrease the setting of V/F curve (Cn-38) in order to prevent the OC protection
function enabled. Normally, the V/F curve need not be changed. (As below)
•Speed search operating V/F curve = Cn-38 * (normal operating V/F curve )

Note : 1. The speed search operation will be disabled if the speed search command is
enacted from the Max. frequency and the setting frequency. (I.e., Sn-25=20,
Sn-26=21 and multi-function input terminals g, h is used at the same time).
2. Make sure that the FWD/REV command must be performed after or at the
same time with the speed search command. A typical operation sequence is
shown below.

Ry1
Speed search command
Ry1 Ry2
RWD/REV run command

3. When the speed search and DC injection braking are set, set the Min.
baseblock time (Cn-37). For the Min. baseblock time, set the time long
enough to allow the motor’s residual voltage to dissipate. If an overcurrent
is detected when starting a speed search or DC injection braking, raise the
setting Cn-37 to prevent a fault from occurring. As a result, the Cn-37
setting cannot be set too small.

57
(33)Low Voltage Alarm Detection Level (Cn-39)
•In most cases, the default setting Cn-39 need not be changed. If an external AC
reactor is used, decrease the low voltage alarm detection level by adjusting Cn-39
setting smaller. Be sure to set a main-circuit DC voltage so that a main circuit
undervoltage is detected.

(34)Slip Compensation Primary Delay Time (Cn-40)

•In most cases, the setting Cn-40 need not be changed. If the motor speed is not
stable, increase the Cn-40 setting. If the speed response is slow, decrease the
setting of Cn-40.

(35)S-curve Characteristic Time at Acceleration Start (Cn-41)

(36)S-curve Characteristic Time at Acceleration End (Cn-42)
(37)S-curve Characteristic Time at Deceleration Start (Cn-43)
(38)S-curve Characteristic Time at Deceleration End (Cn-44)
•Using the S-curve characteristic function for acceleration and deceleration can
reduce shock to the machinery when stopping and starting. With the inverter, S-
curve characteristic time can be set respectively for beginning acceleration, ending
acceleration, beginning deceleration and ending deceleration. The relation between
these parameters is shown in Fig. 28.

(39) PG Parameter (Cn-45)
•The parameter is set in the unit of pulse/revolution. The factory setting is 0.1 P/R.

•Cn-45 and Cn-46 must meet the following relationship:
2 * Cn-45 * Cn-02
< 32767

•If not, an error message “Input Error” will be displayed

•Set the proportion gain and integral time of the speed control (ASR)

(43) ASR Proportion Gain 2 (Cn-49)

•Use these constants to set different proportional gain and integral time settings for
high-speed operation.

•These settings of Cn-51 and Cn-52 will limit the ASR range. See Fig. 44 on page 86.
(47)Excessive Speed Deviation Detection Level (Cn-53)
•This parameter set the level of detecting PG speed deviation. The value of Cn-02 is
referred as 100%, the default unit setting is 1%.
(48)Overspeed Detection Level (Cn-54)
•Set this parameter for detecting overspeed. The value of Cn-02 is referred as 100%,
the default unit setting is 1%. Please refer setting of Sn-43 on page 96.

59
(49) PID Integral Upper Bound (Cn-55)
(50) PID Primary Delay Time Constant (Cn-56)
•Please refer to Fig. 14“Block diagram for PID control in inverter”
•The parameter Cn-55 prevents the calculated value of the integral control of PID
from exceeding the fixed amount. The value is limited within 0-109% of Max.
output frequency (100%). Increase Cn-55 will improve the integral control. If
hunting cannot be reduced by decreasing the Bn-18 or increasing Cn-56, Cn-55
has to decrease. If the setting of Cn-55 is too small, the output may not match the
target setting.
•The parameter Cn-56 is the low-pass filter setting for PID control output. If the
viscous friction of the mechanical system is high, or if the rigidity is low, causing
the mechanical system to oscillate, increase the setting Cn-56 so that it is higher
than the oscillation period. It will decrease the responsiveness, but it will prevent
the oscillation.

(51) Motor Line-to-Line Resistance R1 (Cn-57)

•Set the motor’s terminal resistance (including the motor external cable resistance)
in Ω unit.
•The default setting depends upon the type of inverter (but do not include the motor
external motor cable resistance).
•This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 100.
•Increase the setting when the generating torque is not large enough at low speed.
•Decrease the setting when the generating torque is extremely high and cause
overcurrent trip at low speed.

(52) Motor Rotor Equivalent Resistance R2 (Cn-58)

•Set the motor’s rotor Y-equivalent model resistance in Ω unit.
•The default setting depends upon the type of inverter. Normally this value isn’t
shown on the motor’s nameplate, so it might be necessary to contact motor
manufactor.
•This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 100.

(53) Motor Leakage Inductance Ls (Cn-59)

•Set the motor’s rotor Y-equivalent model leakage inductance in mH unit.
•The default setting depends upon the type of inverter.
•This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 100.
60
(54) Motor Mutual Inductance Lm (Cn-60)
•Set the motor Y-equivalent model mutual inductance in mH unit.
•The default setting depends upon the type of inverter.
•This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 100.

(55) Slip Compensation Gain (Cn-61)

•The parameter Cn-61 improves speed accuracy while operating with a load.
•Usually, the setting Cn-61 need not be changed. Adjust the setting if the speed
accuracy is needed to improve.
•When actual speed is low, increase the set value.
•When actual speed is high, decrease the set value.

(1) Inverter capacity selection (Sn-01)
•The inverter capacity has already been set at factory according to the following
tables. Whenever the control board is replaced, the setting Sn-01 must be set again
according to the following tables.
•Whenever the setting Sn-01 has been changed, the inverter system parameter
settings should be changed based upon the constant torque (CT) load (setting of
Sn-61= 0) or variable torque (VT) load (Sn-61= 1).

*1 Use the variable torque patterns when there is a quadratic or cubic relationship
between the speed and load, such as in fan or pump applications. The user can
properly choose the desired (V/f) patterns (Sn-02=04, 05, 06,or 07) based upon
the load torque characteristics.
*2 In the fan or pump applications, the load torque have a quadratic or cubic
relationship between the speed and load. The inverter capacity rating can be
increased to a value that doubles its own specified capacity rating in some special
case. For example, a 1-Hp inverter can be used to drive a 2-Hp motor with same
voltage class. But, due to the real hardware limitation, 220V 3HP, 10HP and
440V 3HP can not be adapted any larger capacity.

(2) V/F curve selection (Sn-02)

• Set the inverter input voltage (Cn-01) first to match the power supply voltage. The
V/f curve can be set to ant of the following.
Sn-02 = 00~14 : one of 15 pre-set curve patterns
= 15 : V/F pattern can be set by the user through setting of Cn-01~Cn-08

•The parameter is used to select the source of run command.
Sn-04 = 0 : digital operator
1 : control circuit terminal
2 : RS-485 communication
•If Sn-04 is set as 1, the run source is from the control circuit terminal. Under the
initial setting of 2-wire operation (through setting of Sn-03=7 or 9 or 11), the run
source will be FWD/STOP, REV/STOP.
•If Sn-04 is set as 1, the run source is from the control circuit terminal. Under the
initial setting of 3-wire operation (through setting of Sn-03=8 or 10 or 12), the run
source will be RUN, STOP, FWD/ REV.

•After the stop command is input and the minimum baseblock time (Cn-37)
has elapsed, DC injection braking is applied and the motor stopped.
•The DC injection braking time depends upon the output frequency when the
stop command is input and the “DC injection time at stop” setting (Cn-16) as
shown in Fig. 32.
•Lengthen the minimum baseblock time (Cn-37) when an overcurrent (OC)
occurs during stopping. When the power to an induction motor is turned OFF,
the counter-electromotive force generated by the residual magnetic field in
the motor can cause an overcurrent to be detected when DC injection braking
stop is applied.

•Please refer to “Stall prevention level during acceleration” on page 53.

(15) Stall Prevention Selection During Deceleration (Sn-15)

•If external braking resistor unit is installed, the Sn-15 setting must be disabled (Sn-
15= 0).
•If no external braking resistor unit is installed, the inverter can provide about 20%
regenerative braking torque. If the load inertia is so large that it exceeds the
regenerative braking torque, the parameter Sn-15 is set as “1”. When setting Sn-
15= 1 (enabled) is selected, the deceleration time (Bn-02 or Bn-04) is extended so

stall prevention level during running and continues for more than
100ms. The motor is accelerated back to the reference frequency again
when the current falls below this level Cn-26).
•Please refer to “Stall prevention level during running” on page 53.

(17) Operation Selection at Fault Contact during Fault Retrying (Sn-17)

Sn-17 = 0 : Do not output fault restart. (The fault contact does not work)
= 1 : Output fault restart. (The fault contact operates)
•Please refer to “Number of auto restart attempt” on page 52.

(18) Operation Selection at Power Loss (Sn-18)
•This parameter specifies the processing to be performed when a momentary power
loss occurs (within 2 sec)
Sn-18= 0 : When power loss ride through is enabled, operation will be restarted
after a speed search envoked if the power is restored within the allowed
time.
= 1 : When power loss ride-through is disabled the inverter will stop after a
momentary power loss. An undervoltage fault will be detected then. If
the power is interrupted for more than 2 seconds, the fault contact
output will operate and the motor will coast to stop.
(19) Zero Speed Braking Selection (Sn-19)
•The run-source and frequency command is input from control circuit under the
setting of Sn-04=1 & Sn-05=1, If Sn-19 is enabled, the blocking torque will be
generated in DC-braking mode when the frequency command is 0V and forward –
run source is “ON”.
•A time-chart shows the above action as below. The zero-braking selection Sn-19 is
set to 1 and the DC-braking current Cn-15 is limited within 20% of rated current.

(23) Motor Overload Protection Selection (Sn-23)
Sn-23 = 0: Electronic overload protection disable.
Sn-23 = 1~4 : Electronic overload protection enabled. The electronic thermal
overload is detected according to the characteristic curves of
protection operating time. vs. motor rated current setting (Cn-09).
Sn-23 = 1 :The overload is detected according to the standard motor cold start curve.
= 2 : The overload is detected according to the standard motor hot start curve.
= 3 : The overload is detected according to the specific motor cold start curve.
= 4 : The overload is detected according to the specific motor hot start curve.
•Disable the motor protection function (setting 0) when 2 or more motors are
connected to a single inverter. Use another method to provide overload protection
separately to each motor, such as connecting a thermal overload relay to the power
line of each motor.
•The motor overload protection function should be set as Sn-23= 2 or 4 (hot start
protection characteristic curve) when the power supply is turned on or off frequently,
because the thermal values is reset each time when the power is turned off.
•For the motor without forced cooling fan, the heat dissipation capability is lower
when in the low speed operation. The setting Sn-23 can be either ‘1’ or ‘2’.
•For the motor with forced cooling fan, the heat dissipation capability is not
dependent upon the rotating speed. The setting Sn-23 can be either ‘3’ or ‘4’.
•To protect the motor from overload by use of electronic overload protection, be
sure to set the parameter Cn-09 according to the rated current value shown on the
motor nameplate.

controlled through RS-485 port either by MODBUS or PROFIBUS protocol. Please refer to
“7200MA RS-485 MODBUS/PROFIBUS Application Manual”
•The output gain (Bn-14 and Bn-15) will determine the output voltage at multi-
function analog output at AO1, AO2 terminal. The specified multiple of 10V will
correspond to the 100% output monitored value.
(35) Pulse Output Multiplication-Gain Selection (Sn-35)
•If the multi-function output terminal (DO1) be set as pulse output (when Sn-31 or
Sn-32= 14),the final output pulse frequency is the multiple (according to Sn-35) of
the inverter output frequency. Refer to Fig. 46 for pulse signal output.
•Ex1 : when Sn-35= 0, the inverter output frequency is 60Hz, the output pulse
frequency is 60 Hz (duty = 50%).
•Different settings of Sn-35 and their corresponding multiple numbers as shown
below :

(37) RS-485 Communication Baud Rate Setting (Sn-37)
(38) RS-485 Communication Parity Setting (Sn-38)
(39) RS-485 Stopping Method After Communication Error (Sn-39)
•The 7200MA inverter has a built-in RS-485 port for monitoring inverter status and
reading the parameter setting. Under the remote mode operation, the inverter status
and the parameter settings can be monitored. Moreover, the user can change the
parameters setting to control the motor operation.
•7200MA will use MODBUS protocol to communicate with external units by
means of the cable line form RS-485 port.
•Parameter definition is as follows：
•Sn-36： inverter station address, setting range 1~31.
•Sn-37 = 0：1200bps (bps: bit / sec)
= 1：2400bps
= 2：4800bps
= 3：9600bps
•Sn-38 = 0：no parity
= 1：even parity
= 2：odd parity
•Sn-39 = 0： Deceleration to stop with Bn-02 (deceleration time), when RS-485
has communication error.
= 1： Coast to stop
= 2： Deceleration to stop with Bn-04 (deceleration time), when RS-485
has communication error.
= 3： Continue to run (will stop if the key stop is pressed)
•Every data stream has a data length of 11 bits : 1 start bit，8 data bits，1 parity bit
and 1 stop bit. If Sn-38=0, the parity bit is 1.
•3 different commands are used for communication between the inverter and
external units:
a. Read command : external units to read the memory address of the inverter.
b. Write command : external units to write the memory address of the inverter in
order to control the inverter.
c. Circuit test command : To test the communication status between the inverter
and external units.
•The change of setting Sn-36, Sn-37, Sn-38 will be effective in the next start time
after turning off the inverter.
•Do not make the DRIVE/PRGM changeover while writing the date into the
inverter through RS-485 port.

4. Fault display and troubleshooting

4.1 General
The 7200MA have the protective and warning self-diagnostic functions. If fault
occurs, the fault code is displayed on the digital operator. The fault contact output
(RA-RB-RC or R1A-R1B-R1C, DO1, DO2 or R2A-R2C) operates, and the inverter
shut off to stop the motor. If warning occurs, the digital operator will display the
warning code. However, the fault-contact output does not operate. (except some
certain cases, see page on ‘Warning and Self-Diagnosis Functions’). The digital
operator will return to its previous status when the above warning is clear.
•When a fault has occurred, refer to the following table to identify and to clear the
cause of the fault.
•Use one of the following methods to reset the fault after restarting the inverter.
1. Stop the inverter.
2. Switch the fault reset input at terminal f signal or press the RESET key on the
digital operator.
3. Turn off the main circuit power supply and turn on again.

APPENDIX
A. Adjusting PID controller
Use the following procedure to activate PID control and then adjust it while
monitoring the response.
1. Enable PID control.
2. Increase the proportional gain Bn-17 as far as possible without creating oscillation.
3. Decrease the integral time Bn-18 as far as possible without creating oscillation.
4. Increase the derivative time Bn-19 as far as possible without creating oscillation.
The Proportional, Integral and Derivative control function provides closed-loop
control, or regulation, of a system process variable (pressure, temperature, etc.). This
regulation is accomplished by comparing a feedback signal with a reference signal,
which results in an error signal. The PID control algorithm then performs calculations,
based upon the PID parameter settings (Bn-16 through Bn-20 on page 38), on this error
signal. The result of the PID algorithm is then used as the new frequency reference, or is
added to the existing speed reference.
The PID target value can come from the frequency command (from operator) or a
Multi-Function Analog Input.
Select the PID control feedback signal from external terminal AIN for a current
signal (4-20mA DC) or from VIN for a voltage (0-10 VDC).
The Proportional gain is the value by which the error signal is multiplied to generate
a new PID controller output. A higher setting will result in a system with quicker
response. A lower setting will result in a more stable yet slower system.
The Integral Time is a parameter that determines how fast the PID controller will
seek to eliminate any steady-state error. The smaller the setting, the faster the error will
be eliminated. To eliminate the integral function entirely, set this parameter to 0.0
seconds. A lower setting will result in a more responsive system. A higher setting will
result in a more stable yet slower system.
The Integral Upper Limit is a parameter that will limit the effect that the integrator
can have. It works if the PID controller output is positive or negative. It can also be used
to prevent integrator “wind-up.”
The Derivative Time is a parameter that can be adjusted to increase system response
to fast load or reference changes, and to reduce overshoot upon startup. To eliminate the
differential function entirely, set this parameter to 0.00 seconds.
The PID Output Limit (Cn-51, Cn-52) is parameter that can be used to set the
maximum effect the PID controller will have on the system. It also will limit the PID
output when it is either positive or negative.
NOTE : When the PID output limit is reached, the integrator will hold and not change in
value until the PID output is less than the PID output limit.
The PID bias (Bn-20) is a parameter that will add a fixed percentage to the PID
output. It can be used to tune out small system offsets.
NOTE : This parameter is set as a percentage of maximum output frequency.

109
 The above parameters are factory set for optimum results for most applications, and
generally do not need to be changed.
The PID Primary Delay Time is a parameter that adds a filter to the PID output to keep
it from changing too quickly. The higher the setting, the slower the PID output will change.
All of these parameters are interactive, and will need to be adjusted until the control
loop is properly tuned, i.e. stable with minimal steady-state error. A general procedure
for tuning these parameters is as follows:
1. Adjust Proportional Gain until continuous oscillations in the Controlled Variable
are at a minimum.
2. The addition of Integral Time will cause the steady-state error to approach zero.
The time should be adjusted so that this minimal error is attained as fast as possible,
without making the system oscillate.
3. If necessary, adjust derivative time to reduce overshoot during startup. The drive’s
acceleration and deceleration rate times can also be used for this purpose.
Output Before
If overshoot occurs, shorten the derivative
time (D) and lengthen the integral time (I).

G Set-up using the Sensorless Vector Control.
The 7200MA standard with two selectable control modes, V/F control mode
(Sn-67=0) and sensorless vector control mode (Sn-67=1). When the sensorless vector
control mode is selected, be sure to make the inverter capacity and the motor rating
are suitably matched.
The AUTOTUNE feature can be used to identify and store the important motor
parameters for the sensorless control mode.
Refer to p. 60, 61 and 100 to see more details about sensorless vector control.

• The Sequence of Motor Parameter Autotuning:

1. Disconnect the motor load and make sure that the wiring between the inverter
and the motor is suitable. Check the class difference of inverter capacity and
motor rating is less than 2 class or equal.
PRGM
2. Switch to PRGM operation mode by pressing the LCD Digital Operator DRIVE

key.
3. Key in motor rated voltage data to Cn-03 (Max. Output Voltage) and the motor
rated frequency to Cn-04 (Max. voltage frequency) according to the motor’s
nameplate.
4. Enable the Autotuning function by setting Sn-66=1.
PRGM
5. Switch to DRIVE operation mode by pressing the DRIVE key, then run the
inverter by pressing the RUN key.
6. The inverter system immediately enters into the autotuning operation, while
complete (normally, about 25 seconds), the inverter return to stopped condition.
Press the STOP key to stop the parameter autotuning operation while
abnormality occurs during autotuning operation.
7. Finally, press the STOP key to return the system to normal operation mode.
The value of motor parameter will be automatically stored in these parameters
Cn-57 (motor line-to-line resistance R1), Cn-58 (motor rotor equivalent
resistance R2), Cn-59 (motor leakage inductance Ls) and Cn-60 (mutual
inductance Lm).

117
•The Operations and Adjustments of Sensorless Vector Control：

1. Make sure the inverter capacity and motor rating is suitable matched. Used the
AUTOTUNE feature to identify and store the motor parameters in the first time
sensorless vector operation after installation, and key in the motor rated voltage
data onto Cn-03 and the motor rated frequency onto Cn-04 according to the
motor nameplate.
2. Enable the sensorless vector control mode by setting Sn-67=1.
3. Increase the setting Cn-57 to increase the generating torque at low speed.
Decrease the setting Cn-57 to reduce the generating torque to avoid over current
trip at low speed.
4. Adjust the setting Cn-61 if the speed accuracy need to improve. When the actual
speed is low, increase the set value and when the actual speed is high, decrease
the set value.
5. If the motor speed is not stable or the load inertia is too large, increase the
Cn-40 (slip compensation primary delay time) setting.
If the speed response is slow, decrease the setting of Cn-40.
