Cause
Internal communication error.
Measurement circuit fault.
Power unit power supply failure.
Measurement circuit fault.
Number of connected power modules
differs from expected.
Number of inverter modules detected
does not match the value of parameter
95.13 Reduced run mode.
State feedback from output phases
does not match control signals.
• Incorrect parameter setting.
• The charging switch and DC
switch were operated out of
sequence, or a start command
was issued before the unit was
ready.
• Charging circuit fault.
Fault tracing 661
What to do
Contact your local ABB representative.
If the control unit is externally
powered, check the setting of
parameter 95.4 Control board
If the problem persists, contact your
local ABB representative, quoting the
auxiliary code.
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).
Contact your local ABB representative,
quoting the auxiliary code.
Check setting of 95.31 Parallel type
configuration. Cycle the power to the
drive. If the control unit is externally
powered, also reboot the control unit
(using parameter 96.8 Control board
boot) or by cycling its power.
If the problem persists, contact your
local ABB representative.
Check that the value of
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 Reduced run mode
set to 0 (reduced run function
disabled).
Contact your local ABB representative,
quoting the auxiliary code.
• Check the setting of
fuse controller. The parameter
should be enabled only if an xSFC
charging controller is installed.
• The normal power-up sequence
is:
1. Close charging switch.
