Err29 fault in Emotron VS Series Drive

Err29 fault indicates Instantaneous overcurrent. This means there was a sudden, massive spike in output current exceeding the hardware protection limit, usually caused by a short circuit or extreme sudden load. Possible Causes: 1: Inverter output circuit being grounded or short-circuit; 2: The acceleration and deceleration time is too short; 3: Manually torque boost or V/F curve not appropriate; 4: Voltage too low; 5: Start the running motor; 6: Sudden-load in the acceleration process; 7: Model selection of inverter power is too small. Solutions: 1: Troubleshooting peripheral problems; 2: To increase the acceleration time; 3: Adjust the manually torque boost or V/F curve; 4: Adjust the voltage to normal range; 5: Select RPM track start or start after motor stopped; 6: Cancel sudden-load; 7: Select the inverter with higher rating.
