Auto-tuning Interrupted

What does Er - 03 mean?

The auto-tuning process was interrupted because the STOP key was pressed during its operation. This is a user-initiated stop, not an actual system fault, and prevents the tuning from completing.

• Operator inadvertently pressed the STOP key on the drive keypad during the auto-tuning sequence.
• External E-STOP or a control input configured to stop the drive was activated during tuning.
• Momentary loss of control power or power dip interrupting the drive's operation during tuning.
• Communication timeout from a master device (e.g., PLC) configured to stop the drive on error, triggered by tuning delays.
