Title:
Injection molding machine
Document Type and Number:
Japanese Patent JP6234869
Kind Code:
B2
Abstract:
The invention provides an injection molding machine which can restrain stop of a motor caused by overload of a regenerative converter. The injection molding machine comprises a motor, a driving circuit of the motor, a regenerative converter which converts regenerated power from the driving circuit to alternating circuit and supplies the power to a power supply, and a controller which controls the regenerative converter. The controller monitors the regenerated load of the regenerative converter. When the regenerated load exceeds a threshold value, the controller restrains output of the regenerative converter to the power supply.
