Cause
The way the control unit is
powered does not correspond
to parameter setting.
Communication errors
detected between the drive
control unit and the power unit.
Connection between the drive
control unit and the power unit
is lost.
Internal communication error.
Measurement circuit fault.
Power unit power supply
failure.
Measurement circuit fault.
Version check cannot find a
matching power unit FPGA
logic.
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.
What to do
Check setting of 95.04 Control board
supply.
Check the connection between the
control unit and the power unit.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected modules,
"Y YY" specifies the affected BCU control
unit channel (0: broadcast). "ZZ"
specifies the error source (1: Transmitter
side [link error], 2: Transmitter side [no
communication], 3: Receiver side [link
error], 4: Receiver side [no
communication], 5: Transmitter FIFO
error [see "XXX"], 6: Module [xINT board]
not found, 7: BAMU board not found).
"XXX" specifies the transmitter FIFO
error code (1: Internal error [invalid call
parameter], 2: Internal error
[configuration not supported],
3: Transmission buffer full).
Check the connection between the
control unit and the power unit.
Contact your local ABB representative.
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).
Contact your local ABB representative,
quoting the auxiliary code.
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 is set to 0 (reduced run function
disabled).
Contact your local ABB representative,
quoting the auxiliary code.
