Torque control
This chapter explains the torque control under Real sensorless vector control or Vector control.
• Under torque control, output torque is controlled to output the torque as commanded.
• 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.
