3.6.1.1 Undervoltage

„Error! Undervoltage" (E.UP) is triggered if the DC link voltage drops due to brownouts or a generally too weak
power grid. For this error, the automatic restart can be activated.

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.
