Autotuning fault

What does F028 mean?

This ATV310 fault occurs when the drive's auto-tuning function fails to complete successfully. This can be caused by the motor not being properly connected, a motor phase loss during the tuning process, using a special motor type incompatible with standard autotuning, or the motor rotating during the tuning procedure.

• Motor is not connected to the drive output during the autotuning process
• Motor phase loss detected during the autotuning procedure
• Special motor type that is not compatible with the drive's standard autotuning algorithm
• Motor is rotating (e.g., being driven by the load) when autotuning is initiated

Click steps to track your progress.

1. 1

   Check that the motor and drive are compatible for autotuning, referring to documentation.

2. 2

   Verify that the motor is physically connected to the drive's output terminals during the autotuning process.

3. 3

   If an output contactor is being used downstream of the drive, ensure it is closed and energized during auto-tuning.

4. 4

   Check that the motor is completely stopped and uncoupled from the load, if possible, before initiating autotuning.
