Series: SV670N-LK, SV670N-PTC, SV670NS-INT
Main circuit power phase loss
servo drive
Meaning: Drive three-phase input phase loss error
Possible causes
- 1. faulty wiring of the three-phase input cables
- 2. a three-phase servo drive is operating on a single-phase power supply. 3. three-phase power supply imbalance or all three phase voltages are too low.
