Fault tracing 593
5692 PU board powerfail Power unit power supply
failure.
Check the auxiliary code (format
ZZZY YYXX). “YY Y” specifies the
affected inverter module (0…C, always 0
for ZCU control units). “XX” specifies the
affected power supply (1: Power supply
1, 2: Power supply 2, 3: both supplies).
5693 Measurement circuit
DFF
Measurement circuit fault. Contact your local ABB representative,
quoting the auxiliary code.
5694 PU communication
configuration
Number of connected power
modules differs from expected.
Check setting of 95.31 Parallel
connection rating id. Cycle the power to
the drive. If the control unit is externally
powered, also reboot the control unit
(using parameter 96.08 Control board
boot) or by cycling its power.
If the problem persists, contact your local
ABB representative.
5695 Reduced run Number of inverter modules
detected does not match the
value of parameter 95.13
Reduced run mode.
Check that the value of 95.13 Reduced
run mode corresponds to the number of
inverter modules present. Check that the
modules present are powered from the
DC bus and connected by fiber optic
cables to the BCU control unit.If all
modules of the inverter unit are in fact
available (eg. maintenance work has
been completed), check that parameter
95.13 is set to 0 (reduced run function
disabled).
5696 PU state feedback State feedback from output
phases does not match control
signals.
Contact your local ABB representative,
quoting the auxiliary code.
5697 Charging feedback Incorrect parameter setting. Check the setting of 95.09 Switch fuse
controller. The parameter should be
enabled only if an xSFC charging
controller is installed.
The charging switch and DC
switch were operated out of
sequence, or a start command
was issued before the unit was
ready.
The normal power-up sequence is:
1. Close charging switch.
2. After charging finishes (charging OK
lamp lights), close DC switch.
3. Open charging switch.
Charging circuit fault. Check the charging circuit.
With a frame R6i/R7i inverter module, the
auxiliary code “FA” indicates that the
charging contactor status feedback does
not match the control signal.
With parallel-connected frame R8i
modules, the auxiliary code (format
XX00), “XX” specifies the affected BCU
control unit channel.
5698 Unknown power unit
fault
Unidentified power unit logic
fault.
Check power unit logic and firmware
compatibility.
Contact your local ABB representative.
6000 Internal SW error Internal error. Contact your local ABB representative,
quoting the auxiliary code.
