Abstract

See full text

A power supply device for supplying an electric power to a servo amplifier is configured by an AC/DC converter and a power accumulating device. Among a molding cycle, during a process where an amount of consumed power is small, a DC voltage is supplied to the servo amplifier from the AC/DC converter and a power is accumulated in the power accumulating device. In a process such as an injection process where a large power is required, a high DC voltage is supplied to the servo amplifier from the power accumulating device in place of the AC/DC converter.
