Abstract
In an injection molding machine, a control instruction value change unit decreases a control instruction value for each axis when a power outage is detected by a power outage detection unit and returns the control instruction value for each axis to an original value when a power recovery is detected by the power outage detection unit.
Claims6
A control device for an injection molding machine for continuing operation in the event of a power outage and driving an axis by a servo-motor, comprising:
- a driving device configured to drive the servo-motor;
- a power outage detection unit configured to detect a power outage of a power supply to the driving device;
- a molding operation control unit configured to control a molding operation;
- a control instruction value change unit configured to, instruct a change of a control instruction value output from the molding operation control unit to the driving device for each axis to the molding operation control unit, and,
- output an instruction of decreasing the control instruction value for each axis when the power outage detection unit detects a power outage and output an instruction of returning the control instruction value for each axis to an original value to the molding operation control unit when the power outage detection unit detects a power recovery.
