Product Overview

The Yaskawa CIMR-AU4A0023FAA is an A1000 high-performance vector drive designed for 380-480 VAC three-phase industrial motor-control systems. It is rated for 15 HP and 23 A under Normal Duty operation or 10 HP and 18 A under Heavy Duty operation. The dual rating enables the drive to serve both variable-torque equipment and demanding constant-torque machinery.

The A1000 architecture supports open-loop and closed-loop current-vector control as well as open-loop and closed-loop V/f operation. With a compatible feedback option, the drive can receive incremental encoder, supported absolute encoder or resolver information. This expanded feedback capability differentiates the A1000 from compact microdrives and makes it suitable for applications requiring precise speed regulation and dynamic torque response.

Technical Specifications

Compatible System and Applications

The CIMR-AU4A0023FAA is suitable for pumps, fans, conveyors, mixers, machine tools, winders, extruders, packaging systems and process machinery. Normal Duty is generally selected for variable-torque or moderate-overload loads. Heavy Duty provides the stronger short-term overload profile required by machinery with higher starting torque, rapid load changes or frequent acceleration cycles.

Closed-loop control requires a compatible motor encoder, correct feedback option and suitable control parameters. Motor autotuning and encoder direction must be verified before mechanical coupling is fully loaded. Incorrect encoder wiring or motor rotation data can produce unstable control or an immediate feedback-related fault.

Maintenance and Replacement Notes

For an exact replacement, confirm the complete CIMR-AU4A0023FAA code and specification number. Similar A1000 drives can have different enclosure, region, software or factory configuration codes. Record the existing parameter set, motor tuning data, I/O assignments, network address and feedback option before removing the original unit.

Inspect the motor insulation, output cable and mechanical load if the previous drive failed with an overcurrent, ground fault or overload indication. Check cabinet ventilation and heatsink clearance before energizing the replacement. The IP20/NEMA 1 construction is not intended for direct exposure to water, conductive dust or corrosive contamination.

GA800 is the primary migration platform for many A1000 applications. Select the GA800 replacement by voltage, output current and duty rating, and verify mounting, encoder feedback, communication options and safety functions.
