INJECTION MOLDING MACHINE CONTROLLING DRIVE OF MOVABLE PART WITH MOTOR |
摘要 |
In an injection molding machine, a predetermined torque limit value set in advance and acceleration/deceleration torque calculated by an acceleration/deceleration torque calculation section are added to set an output torque limit value for a motor. By this operation, quick acceleration or deceleration can be achieved in an injection process, and breakage of a mold and mechanism section of the injection molding machine can be prevented. |

1. An injection molding machine that controls drive of a movable part with a motor, the injection molding machine comprising:
a speed instruction section for issuing an instruction of a speed and an acceleration of the movable part; an acceleration/deceleration torque calculation section for calculating torque necessary for the change of the speed instructed by the speed instruction section; and an output torque limit setting section for setting an output torque limit for the motor, wherein the output torque limit setting section adds a predetermined torque limit value set in advance and the acceleration/deceleration torque calculated by the acceleration/deceleration torque calculation section to set an output torque limit value for the motor each time the value of the acceleration instructed by the speed instruction section changes. |
