Yaskawa CIMR-AU4A0139FAA A1000 Vector VFD 480V 100HP 139A NEMA 1
Product Overview
The Yaskawa CIMR-AU4A0139FAA is a high-power A1000 vector drive designed for three-phase 380–480 VAC industrial systems. Its normal-duty rating is 100 HP and 139 A, while its heavy-duty rating is 75 HP and 112 A. This allows the same drive platform to support high-capacity variable-torque equipment and demanding constant-torque machinery.
Main Features
- 139 A normal-duty output for high-power pumps, fans and process equipment.
- 112 A heavy-duty output for demanding constant-torque applications.
- Normal-duty overload capacity of 120% for 60 seconds.
- Heavy-duty overload capacity of 150% for 60 seconds.
- V/f and current-vector control with optional closed-loop encoder feedback.
- Flexible programmable I/O for sequencing and machine interlocking.
- Standard Modbus RTU and optional industrial network interfaces.
- Supports engineered external braking arrangements for high-inertia loads.

Compatible System and Applications
This model is suitable for large pumps, fans, conveyors, mixers, crushers, process lines and other high-power industrial machines. Selection should consider continuous motor current, overload duration, ambient temperature, cabinet ventilation and acceleration requirements. Regenerative or rapid-deceleration applications normally require a correctly rated external braking unit and resistor.
Maintenance and Replacement Notes
For installed-base replacement, verify the complete FAA suffix, physical dimensions, input protection, DC reactor arrangement, communication option and control-terminal functions. Archive the existing parameters before removing the original drive. When considering GA800 migration, check the motor-control mode, I/O mapping, network configuration, cabinet space and external braking circuit.
