Description
Yaskawa CIMR-VU2A0020FAA | V1000 Compact Current Vector AC Drive Core Category
Dynamic Product Introduction
Panel builders replacing failing drives on high-cycle machinery often face severe space constraints alongside strict performance demands. The CIMR-VU2A0020FAA resolves these physical and dynamic hurdles by packing high-performance current vector control into a remarkably tight footprint. Rather than relying on sluggish open-loop V/f control, this CIMR-VU2A0020FAA inverter computes motor flux vector components in real-time, delivering high starting torque and rapid response dynamics without requiring external encoder feedback.
Deploying the CIMR-VU2A0020FAA onto production conveyors, pumps, or industrial washers ensures smooth speed transitions while lowering thermal stress on the driven motor. Its integrated auto-tuning routine adapts cleanly to varying motor parameters, making field commissioning straightforward and precise.

Global Sourcing & Live-Test SOP (Transparency Core)
Sourcing surplus or replacement variable frequency drives requires verifying both power section integrity and microchip logic boards. Every secondary-market CIMR-VU2A0020FAA unit passes through a rigorous testing pipeline:
- Inbound Verification: Technicians perform visual checks for capacitor leakage, inspect cooling fan bearing wear, and cross-reference anti-counterfeit holographic labels against Yaskawa production databases.
- Live Simulation: The CIMR-VU2A0020FAA is mounted onto a specialized dynamometer test rig, connected to a 3-phase 230V source, and paired with an equivalent 5 HP induction motor load.
- Diagnostics: Engineers execute static and rotational auto-tuning, run full-speed frequency sweeps up to 120 Hz, and verify dynamic braking transistor response using an oscilloscope and digital multimeter. Units undergo a 4-hour thermal run under full load.
- Final Prep: Fault history registers are completely cleared, parameter sets are reset to factory defaults, and the drive is sealed in an antistatic moisture-barrier bag.
The Field Engineer’s Pitfall Guide
- ❗ DC Bus Capacitor Form Decay: Powering up a surplus that has sat on a shelf unpowered for several years without reforming its electrolytic capacitors can cause internal short circuits. (—though using a variable AC supply to slowly ramp up voltage over an hour prevents catastrophic failure.) I’ve seen maintenance teams blow an entire bank of input rectifiers simply by hitting an aged drive with full line voltage instantly.
- ❗ Carrier Frequency Overheating: Maximizing the PWM carrier frequency above factory defaults to eliminate motor acoustic noise without derating the will trigger premature thermal trips under heavy loads.
- ❗ Sink/Source Logic Jumpers: Forgetting to configure the internal 24V sinking/sourcing (PNP/NPN) input jumper correctly before wiring external PLC command signals results in complete unresponsiveness to start/stop commands.
Intent-Driven FAQ
Will swapping a failed require reprogramming parameters from scratch?
If you have access to a copy of the parameter set saved via Yaskawa’s DriveWizard software or if you swap the detachable digital operator keypad from the old unit, you can easily upload the complete configuration directly into the replacement .
Can this drive run permanent magnet (PM) motors as well as standard induction motors?
Yes. The V1000 firmware architecture natively supports PM open-loop vector control, allowing the to drive high-efficiency interior permanent magnet motors without feedback encoders.
What is the purpose of the built-in RS-485 port on the front terminal strip?
The RS-485/RS-422 interface supports Modbus RTU communication protocol, enabling direct integration with PLCs, SCADA systems, or remote operator interfaces for monitoring and parameter management.
How do I handle an occasional oH (heatsink overheat) fault during peak summer months?
Check the cooling fan intake slots on the bottom of the for dust or lint accumulation. Ambient temperatures exceeding 50 °C require supplemental panel cooling or derating the drive.
What kind of warranty accompanies a surplus or pre-owned unit?
Qualified automation distributors back verified surplus units with a robust 1-year replacement warranty covering both the power stack and control board electronics.
Are you planning to control this drive via hardwired digital/analog signals or through its serial communication network?
