YASKAWA CIMR-AU4A0058FAA – A1000 400V Variable Frequency Drive for 22–30 kW Motors

The YASKAWA CIMR-AU4A0058FAA is an A1000-series AC drive designed for dependable control of 400V-class induction and permanent magnet motors. From my experience, this 58 A frame is a sweet spot for mid-to-large pumps, fans, conveyors, and compressors where you need high torque at low speed and stable process control. You might notice that the “4A” indicates 380–480 VAC operation, and the “0058” current class typically aligns with 22 kW (Heavy Duty) to 30 kW (Normal Duty) motors, which suits many industrial lines without oversizing the cabinet.

Key Features

• Wide control capability – V/f, Open Loop Vector, and Closed Loop Vector control for both IM and PM motors, giving you flexibility across mixed assets.
• High-torque performance – Stable low-speed torque for conveyors, winders, and lifting applications, typically without hunting.
• Built-in RS-485 (Modbus RTU) – Quick integration to most PLCs; optional cards for EtherNet/IP, PROFINET, PROFIBUS, DeviceNet, CANopen, and Modbus/TCP.
• Energy saving for fans/pumps – Automatic energy optimization and sleep/wake functions reduce kWh in variable-torque systems.
• Safe Torque Off (STO) – Dual-channel STO input helps meet machine safety designs (commonly SIL2/Cat.3 on A1000 series).
• Auto-tuning & quick commissioning – Motor auto-tune and an intuitive keypad shorten startup time; parameter copy saves repeat setup effort.
• Robust protection – Overcurrent, overvoltage, ground fault, motor overload, and heatsink temperature protections built in.
• EMC-ready build – The “F” in FAA typically indicates an integrated EMC filter, helping with panel compliance in most cases.

Technical Specifications

Application Fields

This model is commonly selected for:

• Pumps and fans (water, HVAC, cooling towers) where variable-torque control drives energy savings.
• Conveyors and material handling needing smooth starts and accurate speed holding.
• Compressors and blowers that benefit from soft ramping and pressure control loops.
• Machine tools, mixers, and winders using vector control for better low-speed torque.
• Retrofits replacing legacy 400V drives while reusing existing PLC/fieldbus infrastructure.

One thing I appreciate is how forgiving it is on commissioning: auto-tune usually dials in the motor parameters quickly, so you’re not stuck chasing overshoot in your first run. A packaging OEM told us they swapped in this exact rating on a three-line conveyor bank and cut panel heat and noise while keeping the same Modbus mapping—no PLC changes needed.

Advantages & Value

• Reliability – A1000 series drives are known for long service life and strong protection features, which in many cases reduces unplanned downtime.
• Compatibility – Works with both IM and PM motors; straightforward retrofit via built-in Modbus and optional fieldbus cards.
• Cost savings – Energy optimization for fans/pumps and minimal tuning time help trim operating and commissioning costs.
• Support – Clear parameter structure, keypad copy, and widely available documentation make maintenance simpler for onsite teams.

Installation & Maintenance

• Panel standards – Mount vertically in a clean, dry enclosure. Keep recommended clearance above/below the heatsink for airflow; avoid direct heat sources.
• Wiring – Use shielded motor cable for longer runs; land control wiring separately from power to limit noise. Ground per IEC/UL guidance.
• EMC – The FAA variant typically includes an EMC filter; route cables and bond shields correctly for compliance.
• Braking – Dynamic braking is supported; depending on frame size, use the recommended external braking transistor/unit and resistor as specified by Yaskawa.
• Routine care – Inspect fans and heatsinks for dust, check terminals for tightness, review fault history, and perform firmware updates when applicable.
• Environmental – Operate within 0–40 °C without derating (up to 50 °C with derating) and within the humidity limits listed in the manual.

Quality & Certifications

• CE, UL/cUL; RoHS compliant; manufactured under ISO 9001 and typically ISO 14001 processes.
• Safety: STO function commonly certified to SIL2/Cat.3 on A1000 series (model-specific documentation applies).
• Our warranty: 365 days. Manufacturer’s regional policies may vary; documentation provided upon request.
