Undervoltage
The DC-link voltage has gone
below the internal safety limit:
• most probable cause: supply
voltage is too low
• frequency converter internal
fault
• Power outages
In case of temporary sup-
ply voltage break reset the
fault and restart the fre-
quency converter. Check
the supply voltage. If it is
adequate, an internal fail-
ure has occurred.
Contact the distributor
near to you.
