Control Circuit Error

What does CPF00 mean?

A self-diagnostic error has occurred within the drive's control circuit. This indicates an internal problem with the drive's core control logic, which is critical for all operations. This fault can lead to unpredictable drive behavior, unstable control, or complete operational shutdown if not addressed.

Complete Troubleshooting Guide

1. 1

   Cycle power to the drive (turn off, wait for power to fully dissipate, then turn on) and observe if the fault clears.

2. 2

   If the problem persists, contact Yaskawa technical support or your nearest sales representative for guidance on replacing either the control board or the entire drive unit.
