Abstract
A motor control apparatus for an injection molding machine has a control function section for stopping a drive motor; i.e., a servomotor in order to stop a movable member, upon reception of an open signal indicating that a safety door is opened. The motor control apparatus further includes an additional control function section for performing position control for the servomotor, upon reception of the open signal, so as to stop the movable member at a predetermined position. Therefore, when the safety door is opened and thus the open signal is supplied to the additional control function section, the additional control function section performs position control for the servomotor such that the movable member stops at the predetermined position.
