F043
DSP link
The link to the internal signal processor is
interrupted
- 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
60 MHz - 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)
F044
BICO manager fault
A fault has occurred in the softwiring of
binectors and connectors
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).
F045
HW fault on optional
boards
A hardware fault has occurred during access
to an optional board.
- Replace CU board (Compact, chassis units)
- Replace the unit (Compact PLUS)
- Check the connection betewen the subrack
and the optional boards
- Replace optional boards.
F046
Parameter coupling
fault
A fault has occurred during the transfer of
parameters to the DSP.
If fault re-occurs, replace the board/unit
