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 main machine, and the speed control mode is adopted, the other is slave and torque
control is adopted. The actual output torque of the host machine is the torque command of the slave. At this time,
the torque of the slave needs to follow the host quickly, Then the acceleration and deceleration time of torque
control of slave is 0.00s.

Torque control
0: Speed control
1: Torque control
It is used to select the control mode of inverter: speed control or torque control, which cannot be switched
during the operation of inverter.
The X terminal of VH6 has a function related to torque control: torque control inhibition (function 29).
When the speed control / torque control switching terminal is invalid, the control mode is determined by PF-00.
If the speed control / torque control switching is effective, the control mode is equivalent to the reverse value of
PF-00.

PF-01 is used to select the torque setting source, and there are 8 torque setting methods.
The torque setting adopts relative value, and 100.0% corresponds to the rated torque of the motor. The setting
range is -200.0% - 200.0%, indicating that the maximum torque of the inverter is twice the rated torque of the
inverter.
When the torque is given as positive, the inverter operates in positive;
When the torque is given as negative, the inverter operates in reverse.
The torque setting sources are described as follows:
0: Digital setting (PF-02)
It refers to that the target torque directly uses the PF-02 set value.
