Yaskawa Electric Corporation CIMR-VU4A0031FAA Variable Frequency Drive

The Yaskawa CIMR-VU4A0031FAA is a V1000 series variable frequency drive designed for general-purpose industrial motor control. This panel-mounted, IP20/NEMA 1 drive accepts 3-phase 380–480 VAC input and provides 0–480 VAC output with an adjustable 0–400 Hz frequency range, delivering up to ~20 HP (≈15 kW) for AC induction and permanent magnet motors. It uses open-loop vector control and V/f control to optimize speed and torque, supporting conveyors, pumps, compressors, HVAC equipment, and material-handling lines that require reliable variable-speed operation. The V1000 family covers applications from fractional horsepower up to 25 HP in a compact form factor, making it suitable for general-purpose motor speed and torque control. Common replacements include CIMR-AU4A0031FAA, CIMR-VC4A0031FAA, and CIMR-VU4A0031GAA, reflecting its role in retrofit and replacement scenarios.
