○
Used to set the forward or reverse maximum running frequency of the inverter under the torque
control mode.
When the inverter torque control, if the load torque is less than the motor output torque, the motor
speed will continue to rise, to prevent mechanical systems appear coasters and other accidents, must
limit the motor highest speed when torque control.

Under the torque control mode, the difference between the motor output torque and load torque,
determine the speed change rate of the motor and load, so the speed of the motor can be changed
quickly, which brings the problems such as high noise or mechanical stress. By setting the torque
control acceleration and deceleration time, the motor speed can change smoothly.
But for the occasion need torque rapid response, you need to set the torque control acceleration and
deceleration time is 0.00 s.
For example: two motor hard-wired drag the same load, in order to ensure the load uniform
distribution, set a frequency inverter for the host, using the speed control mode, another inverter for
the host and using torque control, the actual output torque of the host as the torque instructions of
slave, the slave torque needs to quickly follow the host at this point, so the torque control acceleration
and deceleration time of slave is 0.00s.
