ST500 | Err.11, what does this message mean and what can you do?
If the error message Err.11 appears on the frequency inverter display, it indicates an overload at the motor.
Causes:
- This message may occur due to insufficient mains voltage, an incorrect setting in the motor protection parameter (F8.03), too high a load on the motor, or the motor being blocked.
Solutions:
- Check the mains voltage and ensure adequate supply to the inverter.
- Check the motor protection parameter F8.03.
- Reduce the load on the motor and check the motor for technical defects.
- Check the motor wiring, especially if the star/delta configuration matches the selected voltage.
