fault
E114 MCB control fault
The common mode motor
voltage of the drive has
exceeded internal fault
limit.
Control board temperature
is
too high.
The desaturation detection
of
the IGBTs in HB1 (half
bridge
1) or HB2 (half bridge 2) of
a
PM has detected a short
circuit.
A PM in the converter
does not
send data to the control
hub
(PM Tx channel fault).
The watchdog supervision
of
the communication link
between BCU and AC500
has
detected a communication
failure.
MCB close command and
MCB close feedback do
not
match.
Check for drive internal ground faults
(secondary cabling, PMs, transformer,
terminal unit).
Check for drive external ground faults
(motor cable, motor windings).
Check the HVD board.
Check for proper cooling of the control
unit cabinet.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Check converter output terminals for a
phase to phase short circuit.
Replace the faulty PM.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Check POF wiring to the PM (or replace).
Check control hub daughter board (or
replace).
Replace the PM
Check Modbus cable.
Check FSCA-01 module.
Check setting of parameter groups 54
FBA B settings, 55 FBA B data in and 56
FBA B data out (changes allowed only by
ABB authorized personnel).
Note: Make sure that up to maximum of
two fieldbus extension modules are used
on the BCU.
Check if MCB has tripped on its own, by
means of short circuit protection relay or
overload protection relay and adapt MCB
protection relay settings if required.
Check MCB control wiring between
ACS580MV and MCB
