Yaskawa CIMR-AU4A0103FAA A1000 Vector VFD 480V 75HP 103A NEMA 1
Product Overview
The Yaskawa CIMR-AU4A0103FAA is a high-capacity A1000 industrial vector drive for three-phase 380–480 VAC systems. It is rated at 75 HP and 103 A in normal duty, or 60 HP and 91 A in heavy duty. The separate ratings allow the drive to be matched to variable-torque equipment or more demanding constant-torque machinery.
Main Features
- 103 A normal-duty output for higher-power variable-torque loads.
- 91 A heavy-duty output with increased short-term overload capacity.
- V/f, open-loop current vector and closed-loop vector control methods.
- Supports induction motors and compatible permanent-magnet motor configurations.
- Optional encoder feedback for closed-loop speed and torque applications.
- Programmable I/O for sequencing, interlocking and speed-reference control.
- External braking equipment can be configured for high-inertia stopping duties.

Compatible System and Applications
The drive can be applied to industrial pumps, fans, compressors, conveyors, mixers, extruders and process-production machinery. Heavy-duty selection is appropriate where the machine requires high breakaway torque or repeated acceleration. Closed-loop performance depends on the correct encoder option, motor data and tuning procedure.
Maintenance and Replacement Notes
Do not select the replacement from the 75 HP title rating alone. Verify whether the installed application uses normal duty or heavy duty and compare the motor nameplate current with the applicable 103 A or 91 A rating. Record all motor, I/O, communication and protection parameters before replacement. External braking units, reactors and filters must be evaluated separately.
