HITACHI AEH020A Servo Drive Module

Product Description

HITACHI AEH020A is a high-performance servo drive module of Hitachi industrial automation series, a compact AC servo amplifier developed to match Hitachi servo motors. It integrates three control modes: position, speed and torque. Built-in dynamic brake and regenerative brake circuits, it features fast response and high positioning accuracy. Its compact structure allows easy cabinet mounting. Suitable for motion control in high-precision automation equipment, widely used for OEM matching and spare parts replacement of imported industrial control machinery.
