Category: Alarm

Cause

1. Supply voltage dropped;
2. Momentary power failure occurred;
3. Undervoltage protection threshold (P06.36) set too high;
4. Drive damaged (Note: this fault is not recorded by default; recording can be configured using P07.22)

Corrective action

1. Increase the supply voltage capacity and ensure a stable supply voltage;
2. With supply voltage confirmed normal, check whether the undervoltage protection threshold (P06.36) is set too high
