OVER SWFREQ
(FF55)
02.19 FW 2 bit 09
Switching frequency is too high. Check motor parameter settings (parameter
group 99 START-UP DATA)
Ensure that ID run has been completed
successfully.
PANEL LOSS
(5300)
02.19 FW 2 bit 13
Control panel or DriveWindow selected as
active control location for drive has ceased
communicating.
Check panel connection (see appropriate
hardware manual).
Check control panel connector.
Replace control panel in mounting platform.
Check Fault Function parameters.
Check DriveWindow connection.
PARAM CRC
(6320)
CRC (Cyclic Redundancy Check) error Switch control board power off and on again.
Reload firmware to control board.
Replace control board.
POWERFAIL
(3381)
INT board powerfail in several inverter units of
parallel connected inverter modules.
Check that INT board power cable is
connected.
Check that POW board is working correctly.
Replace INT board.
POWERF INV xx
(3381)
INT board powerfail in inverter unit of several
parallel connected inverter modules. xx (1...12)
refers to inverter module number.
Check that INT board power cable is
connected.
Check that POW board is working correctly.
Replace INT board.
PPCC LINK
(5210)
02.19 FW 2 bit 11
Fibre optic link to INT board is faulty.
Check fibre optic cables or galvanic link. With
frame sizes R2-R6 link is galvanic.
If RMIO is powered from external supply,
ensure that supply is on. See parameter 16.09.
PPCC LINK xx
(5210)
02.19 FW 2 bit 11
INT board fibre optic connection fault in
inverter unit of several parallel connected
inverter modules. xx refers to inverter module
number.
Check connection from inverter module Main
Circuit Interface Board, INT to PPCC
Branching Unit, PBU. (Inverter module 1 is
connected to PBU INT1 etc.)
PP OVERLOAD
(5482)
Excessive IGBT junction to case temperature.
This fault protects IGBT(s) and it can be
activated by short circuit at output of long
motor cables.
Check motor cables.
RUN DISABLED
(FF54)
02.19 FW 2 bit 04
No Run enable signal received. Check setting of parameter 16.01. Switch on
signal or check wiring of selected source.
SC INV xx y
(2340)
02.18 FW 1 bit 04.
Short circuit in inverter unit of several parallel
connected inverter modules. xx (1...12) refers
to inverter module number and y refers to
phase (U, V, W).
Check motor and motor cable.
Check power semiconductors (IGBTs) of
inverter module.
SHORT CIRC
(2340)
02.18 FW 1 bit 00
Short-circuit in motor cable(s) or motor Check motor and motor cable.
Check there are no power factor correction
capacitors or surge absorbers in motor cable.
Output bridge of converter unit is faulty. Contact ABB representative.
