Sets the torque limit with the communication
terminal of the terminal block.
Sets the torque limit with the FieldBus
communication option.
This enters the torque reference by linking
the common area with the user sequence
output.
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.
Sets the torque limit for forward retrograde (motoring) operation.
Sets the torque limit for forward regenerative operation.
Sets the torque limit for reverse regenerative operation.
Sets the torque limit for reverse retrograde (motoring) operation.
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).
Adjust output voltage compensation values for sensorless vector
control. For output voltage compensation, refer to 5.10.2 Sensorless
Vector Control Operation Guide for Induction Motors on page 193.
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.
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.
