communica-
tion fault
The series connected
capacitors in the DC
link of a PM are
heavily unbalanced.
PM rectifier's diode
open circuit is
detected.
The common mode
motor voltage of the
drive has exceeded
internal fault limit.
Ambient 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.
Check the event log for an auxiliary
code.
The code indicates which PM is
affected.
Replace the faulty PM.
Check the event log for an auxiliary
code.
The code indicates which PM is
affected.
Replace the faulty PM.
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.
