Cause
The hardware of the drive does
not match the information
stored in the memory unit. This
may occur eg. after a firmware
update or memory unit
replacement.
Problem with internal
temperature measurement of
the drive.
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.
What to do
Cycle the power to the drive.
Check the auxiliary code. The auxiliary
code categories are as follows:
1 = PU and CU ratings not the same.
Rating ID has changed.
2 = Parallel connection rating ID has
changed.
3 = PU types not the same in all power
units.
4 = Parallel connection rating ID is active
in a single power unit setup.
5 = It is not possible to implement the
selected rating with the current PUs.
6 = PU rating ID is 0.
7 = Reading PU rating ID or PU type
failed on PU connection.
8 = PU not supported (illegal rating ID).
With parallel connection faults (BCU
control unit), the format of the auxiliary
code is 0X0Y. "Y" indicates the auxiliary
code category, "X" indicates the first
faulty PU channel in hexadecimal (1...C).
(With a ZCU control unit, "X" can be 1 or
2 but this is irrelevant to the fault.)
See A5EA Measurement circuit
temperature (page 573).
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.
