6.4.3 Torque instruction limit
When the absolute value of the torque instruction input by the host computer is greater than the
absolute value of the torque instruction limit, the actual drive's torque instruction is limited and
equal to the limit value of the torque instruction. Otherwise, it is equal to the torque instruction
value input by the host computer.
At any time, there is one and only one torque limit value valid. And the positive and negative
torque limit values do not exceed the maximum torque of the drive and motor and ±300.0% of the
rated torque.

(1) Set torque limit
The torque limit comes from the internal torque. The user needs to set the torque limit. After the
setting, the drive torque instruction will be limited within the torque limit value. When the torque
limit value is reached, the motor will operate with the torque limit value as the torque instruction.
The torque limit value should be set according to the load operation requirements. If the setting is
