KeyPad-1
Sets the torque limit with the keypad.

V1
Sets the torque limit with the analog input
terminal of the terminal block.

6
Int 485
Sets the torque limit with the communication
terminal of the terminal block.
8
FieldBus
Sets the torque limit with the FieldBus
communication option.
9
UserSeqLink
This enters the torque reference by linking the
common area with the user sequence output.
12
Pulse
Sets the torque limit with the pulse input of the
terminal block.
The torque limit can be set up to 200% of the rated motor torque.
Cn.54 FWD +Trq Lmt
Sets the torque limit for forward retrograde (motoring) operation.
Cn.55 FWD –Trq Lmt
Sets the torque limit for forward regenerative operation.
Cn.56 REV +Trq Lmt
Sets the torque limit for reverse regenerative operation.
Cn.57 REV –Trq Lmt
Sets the torque limit for reverse retrograde (motoring) operation.
In.02 Torque at 100%
Sets the maximum torque. For example, if In.02 is set to 200% and an input
voltage (V1) is used, the torque limit is 200% when 10V is entered. However,
when the VI terminal is set up with the factory default setting and the torque
limit setup uses a method other than the keypad, check the parameter
settings in the monitor mode. In the Config Mode CNF.21-23 (only displayed
when using LCD keypad), select 21(Torque limit).
Cn.91-93
SL Volt Comp1-3
Adjust output voltage compensation values for sensorless vector control. For
output voltage compensation, refer to 5.10.2 Sensorless Vector Control
Operation Guide to on page 153.
Cn.52 Torque Out LPF
Sets the time constant for torque command by setting the torque controller
output filter.
Adjust the controller gain according to the load’s characteristics. However, the motor can overheat or
the system may become unstable depending on the controller gain settings.
Note
Speed controller gain can improve the speed control waveform while monitoring the changes in
speed. If speed deviation does not decrease quickly, increase the speed controller P gain or decrease I
gain (time in ms). However, if the P gain is increased too high or I gain is decreased too low, severe
vibration may occur. If oscillation occurs in the speed waveform, try to increase I gain (ms) or reduce P
gain to adjust the waveform.
