Product Overview

The Yaskawa CIMR-AU4A0058FAA is an A1000 series industrial vector drive designed for three-phase 380–480 VAC power systems. It provides a rated output of 58 A and 40 HP under normal-duty operation, or 45 A and 30 HP under heavy-duty operation. The dual-rating design allows the drive to be selected according to the actual overload, acceleration and torque requirements of the machine.

Main Features

• 40 HP and 58 A normal-duty rating for variable-torque and moderate-overload applications.
• 30 HP and 45 A heavy-duty rating for constant-torque machinery.
• Supports V/f control, open-loop current vector control and closed-loop vector control.
• Optional encoder feedback capability for applications requiring improved speed and torque regulation.
• Normal-duty overload capacity of 120% for 60 seconds.
• Heavy-duty overload capacity of 150% for 60 seconds.
• Built-in braking transistor for connection to a correctly selected braking resistor.
• Standard Modbus RTU communication with optional industrial network interfaces.

Technical Specifications

Compatible System and Applications

The CIMR-AU4A0058FAA is suitable for conveyors, mixers, extruders, pumps, fans, machine tools, packaging equipment and material-handling systems. Heavy-duty selection is recommended for high starting torque, frequent acceleration or repeated load changes. Closed-loop vector operation requires a compatible feedback option and matching motor encoder.

Maintenance and Replacement Notes

Before replacement, verify the complete model number, input voltage, motor full-load current, duty mode, control wiring and installed option cards. Existing motor, I/O, communication and protection parameters should be recorded before removing the original drive. When replacing the A1000 with a newer GA800 drive, verify cabinet dimensions, terminal assignments, communication options, braking equipment and parameter conversion requirements.
