3.6.1.1 Undervoltage
"Error ! Undervoltage "(E.UP) is triggered if the DC link voltage drop due to voltage dip or generally at low net-
work. The automatic restart can be activated for this error.
3.6.1.2 Overvoltage
"Error ! Overvoltage" is triggered if the DC link voltage increases beyond the overvoltage level.
3.6.1.3 Overcurrent
The "Error! Overcurrent“ (E.OC) is triggered, if the „OC tripping current“ (see technical data in the instruction
manual) is exceeded.
If this error occurs permanently, either the parameter setting is not correct or the COMBIVERT is defective.
