Yaskawa CIMR-G3U4030 Variable Frequency Drive

The Yaskawa CIMR-G3U4030 Safetronics Varispeed AC Drive is a 3‑phase variable frequency drive designed for industrial motor control, converting 380–480 VAC input to regulate speed and torque for AC induction motors in conveyors, pumps, compressors, and other heavy‑duty equipment. This ~30 kW (40 HP) class drive typically delivers about 60–70 A output, using a PWM inverter with V/f control and early vector capability, and it is panel‑mounted for industrial installations. Belonging to the Safetronics/Varispeed G3 family, it is commonly used for replacement or retrofit in legacy Safetronics and G‑series drives, with common replacements including CIMR-G7A4030, CIMR-AU4A0031FAA, and CIMR-AC4A0031FAA.
