• Under torque control, the operation is controlled to output the commanded torque.
• Motor rotation speed is steady when the motor output torque and load torque are balanced.
Thus, motor speed during torque control is determined by the load.
• Under torque control, motor speed accelerates so motor output torque does not exceed motor load. In order to
prevent the motor from overspeeding, set a speed limit. (Speed control is performed instead of torque control during
speed limit.)
• If speed limit is not set, speed limit value setting is regarded as 0 Hz and torque control is not enabled.
