Inovance E030.1 fault code meaning
Inovance / E030.1
Series: MD520
Load loss fault
AC drive
Meaning: Asynchronous motor: This fault is triggered during run when the output current is below 25% no-load current and the synchronous frequency is below 90% rated frequency. Synchronous motor: This fault is triggered when the output current is below the load loss current threshold (default: 10%) and either the current reference exceeds the rated current or the output voltage exceeds the detection threshold (detection threshold: 50% × (back EMF +0.25 times the rated voltage)).
Possible causes
- AC drive output phase loss
