Yaskawa CIMR-F7U4055 Variable Frequency Drive

The Yaskawa CIMR-F7U4055 Varispeed F7 AC Drive is a 100 HP three-phase variable frequency drive designed to precisely control motor speed and torque in high-power industrial systems. It accepts 3-phase input at 380–480 VAC and delivers adjustable 0–480 VAC output with an output frequency range from 0 to 400 Hz and a current rating around 125 A, making it suitable for conveyors, pumps, compressors, and heavy machinery. Part of the Varispeed F7 series, this PWM-based VFD supports V/f and vector control methods and uses a 3-phase input/output configuration with a typical NEMA 1 enclosure, aligning with general-purpose industrial drive applications. Common replacements include CIMR-F7A4055, CIMR-F7Z4055, and CIMR-F7U4075, reflecting its role in retrofit and maintenance of large-scale drive systems.
