Current control loop is not tuned

What does 4068 mean?

The current control loop has not been properly tuned before attempting rotor parameters autotuning, specifically applicable to asynchronous motors. Proper current loop tuning is a prerequisite for accurate rotor parameter identification.

• Rotor parameters autotuning initiated before the current control loop was tuned.
• Skipped or incomplete current loop tuning during the commissioning process.
• Incorrect motor type selected, leading to an expectation of current loop tuning when it hasn't occurred.
• Corruption of tuning parameters requiring a re-tune.

Click steps to track your progress.

1. 1

   Re-run the full autotuning process, ensuring the current control loop tuning step is successfully completed first.

2. 2

   Verify that the correct motor type (asynchronous motor) is selected in the drive parameters for which this tuning is applicable.

3. 3

   Check drive diagnostics for any errors or warnings related to the current control loop tuning process itself.

4. 4

   Ensure all motor nameplate data (e.g., current, voltage, speed) are accurately entered before starting autotuning.
