Sets the torque limit with the FieldBus
communication option.
Sets the torque limit with a user sequence
output. The torque reference is received via
the common area addresses.
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 reverse torque limit for forward operation.
Sets the regenerative torque limit for forward operation.
Sets the regenerative torque limit for reverse operation.
Sets the reverse torque limit for reverse operation.
Sets the maximum torque. For example, if In.02 is set to 200%
and an input voltage (V1) is used, the torque limit will be 200%
when 10 V is entered. However, when the V1 terminal is set to the
factory default setting and the torque limit input source is any
device other than the keypad, check the parameter settings in
Monitor mode. Set CnF.21–23 (only displayed when an LCD
keypad is used) to 21 (Torque limit).
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 can become unstable depending on the controller gain settings.
Speed controller gain can improve the speed control waveform while monitoring the changes in
speed. If the speed deviation does not decrease fast enough, increase the speed controller P
gain or decrease I gain (time in ms). However, if the P gain value is increased too much or the I
gain value is decreased too much, severe vibrations may occur. If oscillation occurs in the speed
waveform, try to increase the I gain (ms) or reduce the P gain to adjust the waveform.
