ENERGY SAVING CONTROLLER AND APPARATUS OR INJECTION MOLDER IMPLEMENTING THE SAME

摘要

PURPOSE: A control device for saving energy and an injection-molding machine equipped with the same are provided to save energy of an existing device with an oil-hydraulic circuit by the attachment of a control device for saving energy on an oil-hydraulic circuit or oil pressure equipment. CONSTITUTION: A control device(100) for saving energy comprises a solenoid operation detection unit(111), a motor RPM determining unit(112), and an inverter(101). The solenoid operation detection unit detects the operation state of the solenoid with being connected to one or more solenoids. The valve varies the flow direction of the working fluid of an oil-hydraulic circuit. The motor RPM determining unit determines the RPM(Revolution Per Minute) of an induction motor(60) based on the detection result of the solenoid operation detection unit. The inverter is serially connected between the induction motor and the power supply unit.
