Torque Control
The torque control function controls the motor to maintain the preset torque value. The motor
rotation speed is constant when the output torque and load torque are balanced. Therefore, the
motor rotation speed is decided by the load when controlling the torque.
When the motor output torque is greater than the load torque required, the speed of motor
becomes too fast. To prevent this, set the speed limit. (The torque control function cannot be used
while the speed limit function is running.)

Note
•
To operate in torque control mode, basic operation conditions must be set. For more information,
refer to .
•
The torque control cannot be used in a low speed regeneration area or low load conditions.
•
If you change the rotation direction while operating, an over current trip or low speed reverse
direction error will be generated.
