Converter Faults
When a fault is generated in the Converter, that fault is passed to the Inverter
so all the faults are recorded in the Inverter fault queue. Faults in the
converter are numbered 1 to 99.
When using PowerFlex 700 Vector Control, the fault from the Converter is
added to a base number of 300, so all the Converter faults are numbered 301
to 399. The pop-up window on the HIM alerts the user to look at the fault
log in the PF700AC to get the specific fault text.
When using PowerFlex 700S Phase II Control, the faults from the Converter
are all combined into one fault code (F110) in the Inverter. The pop-up
window on the HIM alerts the user to look at the fault log in the PF700AC
to get the specific fault text.
For a complete listing of Converter faults, descriptions, and actions, please
refer to the PowerFlex 700L Active Converter User Manual (publication
PFLEX-UM002…).

Port 6 Adapter F76 Communication adapter on DPI port 6 reported
a fault.
Check communication cable and check adapter fault queue
for information about the fault.
Port 6 DPI Loss F86 DPI Communications to port 6 was lost. If adapter was not intentionally disconnected, check wiring.
Replace wiring, port expander, or Main Control Board as
needed. Check HIM connection.
