Abstract

See full text

Provided is a numerical control system of an industrial machine that makes it possible to eliminate overshoot occurred at the time of stopping, thereby preventing interference of the machine, for example, in a case in which the torque of a motor such as a servomotor used in a feed axis of a machine tool is limited by a command unit of a CNC. A numerical control system of an industrial machine includes a command unit and a control unit configured to control driving of a motor of the industrial machine in accordance with a command from the command unit, and to perform position control by receiving a command of an end point position from the command unit or without receiving a command of the end point position from the command unit, and the control unit includes an in-deceleration torque limit release unit that, in a case of performing torque limitation of the motor, releases the torque limitation only during deceleration.
