Yaskawa CIMR-G5U40P4 AC Variable Frequency Drive

The Yaskawa CIMR-G5U40P4 Varispeed 616G5 AC Drive is a compact 3-phase variable frequency drive designed to control motor speed and torque while improving energy efficiency in industrial automation applications. It accepts three-phase input in the 380–480 VAC range (typical 400 V class); output is an adjustable AC signal proportional to frequency with an output frequency up to ~400 Hz and an output current of about 1.8–2.2 A, delivering a 0.75–1 HP class drive and supporting both V/f and vector control capability. Designed for AC 3-phase induction motors, the CIMR-G5U40P4 is intended for panel mounting in environments with a typical NEMA 1 / IP20 enclosure, making it suitable for general-purpose motor speed and torque control in conveyors, pumps, fans, HVAC equipment, and light-duty manufacturing lines. Common replacements in the Varispeed 616G5 family include CIMR-AU4A0002FAA, CIMR-VB4A0002BAA, and CIMR-V7CU40P2, reflecting its role in replacement and retrofit projects for legacy inverter drive systems.
