Protective
Function

Ground Fault

Grounded output. The protecction is effective for Drive output
terminals - U, V, W.
GROUND FAULT EF, (during CONST. SPD) Operating conditions that need to be reviewed:
Protective
Function
Over voltage Protects the Drive when the DC bus voltage reaches the
momentary overvoltage protection level by a braking operation.
(Drive cannot protect against an input line overvoltage.)
