  • Page 76 Before operation <Selection method of torque control> Torque control is exercised to develop torque as set in the torque command. The motor speed becomes constant when the motor output torque and load torque are balanced. For torque control, therefore, the speed is determined by the load. For torque control, the motor gains speed as the motor output torque becomes greater than the motor load.
