What does 11 mean?
The current measurement system has detected that there is no current flowing in one of the motor phases. This typically indicates a broken motor cable, a loose connection, or an open winding in the motor itself. Running a motor with a missing phase can cause severe damage to the motor and the drive output stage.
Complete Troubleshooting Guide
- 1
Check all motor cables for breaks, loose connections, or damage.
- 2
Inspect the motor windings for an open circuit or internal fault.
