Faults and Alarms
Number / Fault Cause
F043 The link to the internal signal processor is
interrupted
DSP link
F044 A fault has occurred in the softwiring of
binectors and connectors
BICO manager fault
F045 A hardware fault has occurred during access
to an optional board.
HW fault on optional
boards
F046 A fault has occurred during the transfer of
parameters to the DSP.
Parameter coupling
fault
12-4
Counter-measure
- Reduce pulse frequency (perhaps caused by
calculating time overflow)
- If fault re-occurs, replace the board/unit
The pulse frequency P340 should not be
adjusted to values larger than 7.5 kHz (for
60MHz - DSP) or 6 kHz (for 40MHz - DSP). If
higher values are set, indices 12 to 19 have to
be checked on visualization parameter r829.
The indicated free calculating time of the DSP
time slots always have to be greater than zero.
If the calculating time is exceeded, this is also
displayed by fault F043 (DSP coupling).
Remedy: Reduce pulse frequency (P340)
Fault value r949:
>1000: Fault during connector softwiring
>2000: Fault during binector softwiring
- Voltage OFF and ON
- Factory setting and new parameterization
- Exchange the board
1028:Link memory is full. The link area
between the two processors is full. No further
connectors can be transferred.
- Reduction of the linked connections between
the two processors. Interface between the two
processors is position control/setpoint
conditioning i.e.softwires from and to the
setpoint conditioning, position controller,
speed controller, torque interface and current
controller which are not necessary should be
dissolved to reduce the link (value 0).
- Replace CU board (Compact, chassis units)
- Replace the unit (Compact PLUS)
- Check the connection betewen the subrack
and the optional boards
- Replace optional boards.
If fault re-occurs, replace the board/unit
