Yaskawa CIMR-P5M4037 Variable Frequency Drive

The Yaskawa CIMR-P5M4037 (GPD506 / P5 series) is a heavy-duty AC variable frequency drive designed for high-power motor control in manufacturing and process environments. It converts fixed 3-phase 380–460 VAC input into adjustable 0–460 VAC 3-phase output to precisely control speed, torque, and acceleration of large motors, delivering about 50 HP with input current around 88 A and output current ~80 A (VT) or ~64 A (CT). The drive provides a 0–400 Hz output and overload capability of 120–150% for 60 seconds, using PWM inverter control. Features include PID control, energy-saving mode, and power monitoring, all housed in a panel-mounted large-frame enclosure weighing around 48 kg. As a flagship GPD506/P5 general-purpose drive, it has been widely used to regulate pumps, fans, compressors, conveyors, and process-control equipment in HVAC and heavy industrial plants where reliable speed and torque control are essential. This CIMR-P5M4037 is a discontinued/legacy product, with common modern replacements from Yaskawa including the A1000 and GA800 series, or the P7 line for HVAC and process applications.
