Code Description
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 reverse torque limit for forward operation.
Cn.55 FWD –Trq Lmt Sets the regenerative torque limit for forward operation.
Cn.56 REV +Trq Lmt Sets the reverse torque limit for reverse operation.
Cn.57 REV –Trq Lmt Sets the regenerative torque limit for reverse 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 will be 200% when 10
V is entered. When the torque limit input source is any device other
than the keypad, Torque limit can be viewed in the Monitor mode.
Set one of CnF.21–23 (only displayed when an LCD keypad is used)
to 21 (Torque limit).
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 can 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 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.
