Cause : Intermediate circuit DC voltage is oscillating due to missing input power line phase or blown fuse.
Alarm is generated when DC voltage ripple exceeds 14% of nominal DC voltage.
Programmable fault function
parameter - 3016 SUPPLY PHASE
1.Check input power line fuses.
2. Check for input power supply imbalance.
3. Check fault function parameter setting.
