Yaskawa CIMR-V7CU43P7 AC Variable Frequency Drive

The Yaskawa CIMR-V7CU43P7 Varispeed V7-4X AC drive is a compact, general-purpose variable frequency drive that provides precise speed and torque control for AC motors in industrial automation. It supports V/f and open-loop vector control and is commonly applied in conveyors, pumps, fans, and packaging lines, as well as material handling systems and machine tools, enabling energy efficiency and smoother operation. Key specifications include a 3-phase input of 380–460 VAC with an adjustable 0–460 VAC output, 8.6 A output current, and a ~3.7 kW (≈5 HP class) rating, with an output frequency range of 0–400 Hz, and 150% overload capability for 60 seconds. Communication is via RS-485 or RS-422, and the unit is available in a NEMA 4X / Type 12 enclosure variant (V7-4X), weighing about 13 pounds. It is designed for AC 3-phase induction motors and is part of Yaskawa’s Varispeed V7 family, commonly used for replacement or retrofit in older V7 drive systems. Common replacements include CIMR-V7AZ40P7, CIMR-V7NU43P7, CIMR-AB4A0007FMA.
