Product Overview

The Yaskawa CIMR-AU4A0088FAA is an A1000 vector drive designed for three-phase 380–480 VAC industrial power systems. It delivers 88 A with a nominal 60 HP normal-duty rating and 75 A under heavy-duty operation. The drive is intended for industrial applications requiring flexible motor-control methods, configurable I/O and reliable overload performance.

Main Features

• 88 A normal-duty output for moderate-overload and variable-torque equipment.
• 75 A heavy-duty rating for applications requiring increased starting and transient torque.
• Supports V/f, open-loop vector and closed-loop vector control.
• Optional feedback hardware for encoder-based speed and torque regulation.
• Programmable digital and analog I/O for machine-control integration.
• Standard serial communication with optional industrial network interfaces.
• External braking equipment can be selected for rapid deceleration or regenerative loads.

Technical Specifications

Compatible System and Applications

The CIMR-AU4A0088FAA is suitable for larger conveyors, extruders, mixers, process machines, high-inertia equipment and general production lines. Application selection should be based on motor full-load current and required overload capacity. Rapid stopping or overhauling loads normally require a correctly selected external braking unit and braking resistor.

Maintenance and Replacement Notes

Before installation, compare the original drive nameplate, motor current, control mode, carrier frequency, encoder option, communication card and terminal assignments. For used equipment, the cooling fans, DC bus, power terminals and stored fault history should be inspected. When migrating to GA800, verify the converted parameters through functional commissioning on the actual machine.
