Yaskawa Electric Corporation CIMR-MR5A2018 Servo Drive

The CIMR-MR5A2018 is a VS-656MR5 spindle converter from Yaskawa Electric that provides regulated DC power to spindle inverter systems in CNC spindle drives, delivering 22.9 kW of output (30 kVA) from a 230V AC three-phase input for high-performance motor speed and torque control, with precise speed control, rapid acceleration and deceleration, and regenerative braking. This panel-mounted industrial converter is used in CNC machining centers, milling machines, CNC lathes, and automated metalworking systems to power spindle motors with a stable DC bus and regenerative energy handling, working with Yaskawa spindle inverter systems. As a legacy/discontinued unit, it appears in surplus and refurbishment markets, with common replacements including Yaskawa Electric CIMR-M5A20180-XXXA, CIMR-MR5A2015, and GA700 Industrial Drive.
