Current control loop is not tuned
ABB · Application Error ABB Motion Drives Error trouble shoo
¿Qué significa 4068 ?
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.
Causas comunes
- 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.
Pasos de reparación & Lista de verificación

- 1
Re-run the full autotuning process, ensuring the current control loop tuning step is successfully completed first.
- 2
Verify that the correct motor type (asynchronous motor) is selected in the drive parameters for which this tuning is applicable.
- 3
Check drive diagnostics for any errors or warnings related to the current control loop tuning process itself.
- 4
Ensure all motor nameplate data (e.g., current, voltage, speed) are accurately entered before starting autotuning.
