Fault Occurs Simultaneously with Power Loss
WARNING!
Sudden Movement Hazard. Ensure there are no short circuits between the main circuit terminals (U, V, W) or between
the ground and main circuit terminals before restarting the drive. Failure to comply may result in serious injury or death
and will cause damage to equipment.
