YASKAWA CIMR-AU4A0165FAA A1000 – High‑performance 480 V Variable Frequency Drive for IM & PM Motors
The YASKAWA CIMR-AU4A0165FAA belongs to the A1000 series, a workhorse AC drive that handles both induction motors (IM) and permanent magnet (PM) motors with clean, consistent torque. From my experience, it’s a smart choice when you need dependable vector control on 380–480 V lines, especially in plants where uptime and energy efficiency actually matter. You might notice that it drops into retrofit jobs easily, thanks to rich I/O, standard Modbus, and a long list of fieldbus card options.

Application Fields
This model suits mid‑to‑large loads on 480 V systems where smooth speed control, energy savings, and reliable torque are needed:
- HVAC: large supply/return fans, cooling towers, and high‑lift pumps
- Water & wastewater: aeration blowers, clarifier drives, and transfer pumps
- Metals & mining: conveyors, feeders, and process mixers
- Food & beverage: augers, homogenizers, screw compressors
- General manufacturing: extruders, winders, test stands, and machine retrofits
A customer in a plastics plant told me the A1000 “just behaves” during wide speed swings on a 480 V extruder, especially with the built‑in PID and speed search features minimizing process upsets after power dips.
Advantages & Value
- Reliability – A1000 is known for long service life; the protective diagnostics seem to be spot‑on for most plants.
- Compatibility – Works with existing PLCs over Modbus or standard fieldbus cards; handles both induction and PM motors.
- Energy & process savings – Energy optimization and stable vector control typically reduce kWh and scrap, especially on variable torque loads.
- Lifecycle support – Parameter copy, DriveWizard tools, and widely available spares make maintenance straightforward.
- Procurement-friendly – Short lead options, global approvals, and predictable commissioning help reduce project risk.
Installation & Maintenance
- Cabinet & ventilation – Mount vertically in a clean, dry panel; allow clearances per manual (top/bottom for airflow). For enclosed cabinets, plan for forced ventilation or a heat exchanger.
- Wiring – Use shielded control wiring, segregate power/control, and bond ground to a low‑impedance earth. On long motor leads, consider a dV/dt filter or sine filter.
- Power quality – A line reactor or DC choke is recommended in most cases to reduce harmonics and protect the rectifier. Add an EMC filter where required by local standards.
- Braking & dynamic stops – For high‑inertia loads, size an external braking resistor module if fast decel is required.
- Safety – Use the Safe Torque Off (STO) inputs as part of a validated safety circuit (SIL2/PLd architectures). Verify stop category requirements.
- Routine maintenance – Clean heatsink and intake filters, check fans annually, re‑torque terminals, and back up parameters. Firmware updates via keypad/DriveWizard when applicable.
- Commissioning tips – Run motor auto‑tune, set proper accel/decel ramps, enable energy‑saving where appropriate, and log key alarms during trial runs.
Quality & Certifications
- CE, UL, cUL, and RoHS compliant (A1000 series, region dependent)
- Functional safety: STO suitable for SIL2 / PL d when correctly integrated
- Manufactured under ISO 9001 quality systems
- Warranty: 365 days
