Abstract
An injection molding machine has a control device which controls an input to an incorporated motor. The control device sets a setting value a setting value of the motor to be held for a predetermined setting time. Additionally, the control device determines a reduction ratio which causes the setting value to be reduced according to passage of time, and controls the input to the motor based on the reduction ratio. Thereby, a power consumption of the motor is reduced.
Claims14
A control method of controlling an input to a motor incorporated in an injection molding machine based on a setting pressure so as to reduce energy consumption of said motor, comprising:
- setting a pressure setting value for an output of the motor to be held for a predetermined setting time;
- setting a reduction ratio to reduce the pressure setting value in accordance with passage of time;
- and
- controlling the input to said motor based on the reduction ratio.
An injection molding machine having a control device for controlling an input to an incorporated motor so as to reduce energy consumption of said motor, the control device comprising:
- setting means for setting a pressure setting value for an output of the motor to be held for a predetermined setting time;
- and
- determining means for determining a reduction ratio to reduce the pressure setting value in accordance with passage of time;
- wherein the control device is configured to control the input to said motor based on the reduction ratio.
