Yaskawa CIMR-AU4A0072FAA A1000 Vector VFD 480V 50HP 72A NEMA 1
| Place of Origin | USA |
| Brand Name | YASKAWA |
| Model Number | CIMR-AU4A0072FAA |
Product Overview
The Yaskawa CIMR-AU4A0072FAA is a 380–480 VAC A1000 industrial vector drive rated at 50 HP and 72 A in normal duty, or 40 HP and 60 A in heavy duty. Its dual-rating design allows engineers to size the drive according to motor current, required starting torque and application overload rather than nominal motor horsepower alone.
Main Features
- 72 A normal-duty output for variable-torque and moderate-overload equipment.
- 60 A heavy-duty output for constant-torque production machinery.
- V/f, open-loop current vector and closed-loop vector control methods.
- Optional encoder feedback for precise speed and torque control.
- 120% normal-duty overload and 150% heavy-duty overload for 60 seconds.
- Built-in braking transistor for an appropriately engineered dynamic-braking circuit.
- Built-in Modbus RTU communication with optional Ethernet and fieldbus interfaces.

Compatible System and Applications
This model can be used with conveyors, compressors, centrifuges, process pumps, mixers, packaging machines and general production equipment. The heavy-duty rating should be used where the machine requires high breakaway torque, short acceleration times or frequent load changes. Motor current and thermal loading must be verified during selection.
Maintenance and Replacement Notes
Confirm the full FAA suffix, supply voltage, motor current, braking arrangement, communication network and installed feedback card before replacement. Record the existing parameter set and terminal functions before removing the original drive. GA800 may be considered for modernization, but it should not be treated as a direct plug-in replacement without checking dimensions, wiring, options and parameter assignments.
