Under the torque control mode, the difference between the motor output torque and the load torque determines
the speed change rate of the motor and the load. The motor speed may change rapidly, causing problems such as
noise or excessive mechanical stress. By setting the acceleration and deceleration time of torque control, the
motor speed can change smoothly.

In the torque control of small torque starting, it is not recommended to set the torque acceleration and
deceleration time. If the torque acceleration and deceleration time is set, it is suggested to increase the speed
filter coefficient properly. When torque quick response is needed, torque control acceleration and deceleration
time is set to 0.00s.
For example, two motors in hard connection drive the same load. In order to ensure the load distribution evenly,
one inverter is set as the master, and the speed control mode is adopted, the other is slave and torque control is
adopted. The actual output torque of the master is the torque command of the slave. At this time, the torque of
the slave needs to follow the master quickly, then the acceleration and deceleration time of torque control of
slave is 0.00s.

The above parameters are used for fixed length control.
In the application, it is necessary to set the corresponding input terminal function as "length counting input"
(function 22). When the pulse frequency is high, the X4 port must be used. The actual length A0-01 can be
calculated by dividing the number of pulses sampled by terminals and A0-02. When the actual length is greater
than the set length A0-00, the multi-function digital Y outputs the "length reached" ON signal. In the process of
fixed length control, the length reset operation (function 23) can be carried out through the multi-function X
terminal.
