ABSTRACT:
A motor controller drives and controls a motor to drive a shaft subject to gravity. The motor controller includes a PI control unit which controls the velocity of the motor, a brake which prevents the falling of the shaft in accordance with a brake signal, and a storage unit which detects the brake signal input to the brake. On the basis of the state of the detected brake signal, the storage unit stores the torque command value when the brake signal has changed from off to on, and sets the stored torque command value to an integral component of the PI control unit when the brake signal has changed from on to off.
