Yaskawa CIMR-R5U4018 AC Drive Varispeed Series

The Yaskawa CIMR-R5U4018 Varispeed 656RC5 regenerative drive combines precise speed control of AC 3-phase induction motors with regenerative braking to capture and feed energy back into the DC bus in high-inertia industrial systems. This panel-mounted AC drive accepts 3-phase 380–480 VAC input and delivers a DC bus regenerative interface through a PWM inverter with regenerative capability, enabling effective energy management for braking. It is commonly installed in conveyors, cranes, hoists, elevators, and other heavy machinery where controlled deceleration and energy recovery reduce heat in braking components and improve overall system efficiency. Manufactured by Yaskawa Electric Corporation, the CIMR-R5U4018 is part of the Varispeed 656RC5 series and is designed for regenerative energy control and braking management across applications requiring energy feedback to the power system. It is compatible with AC 3-phase induction motors, mounting as a panel-mounted industrial unit, and features a key capability to reduce the need for external braking resistors while dissipating excess energy efficiently. Common replacements include CIMR-G7A4018, CIMR-AU4A0018FAA, and CIMR-AC4A0018FAA.
