Current Measurement Failure

What does 2211 mean?

A failure has occurred in a current transformer within the output current measurement circuit. This will lead to inaccurate or no current feedback for the drive, severely impacting motor control, protection functions, and overall drive performance.

• Failure in the current measurement circuitry (e.g., current transformers, Hall effect sensors).
• Internal fault within the drive's current sensing hardware.
• Open circuit or short circuit in the current sensor signal path.
• Incorrect current sensor calibration or configuration (P1-01, P1-02).
