Number / Fault
Cause
F027
Pulse resistance fault (only Compact PLUS) /
UCE Phase L3 (chassis)
Pulse resistor fault /
UCE Phase L3
F029
A fault has occurred in the measured value
sensing system:
Meas. value sensing
- (r949 = 1) Offset adjustment in phase L1 not
Compact PLUS only
possible
- (r949 = 2) Offset adjustment in phase L3 not
possible.
- (r949 = 3) Offset adjustment in phases L1
and L3 not possible.
- (r949=65) Autom. Adjustment of the analog
inputs is not possible
F035
Parameterizable external fault input 1 has
been activated.
External fault 1
F036
Parameterizable external fault input 2 has
been activated.
External fault 2
F038
A voltage failure has occurred during a
parameter task.
Voltage OFF during
parameter storage
F040
Incorrect operating status
Internal fault of
sequence control
F041
A fault has occurred during the storage of
values in the EEPROM.
EEPROM fault
F042
The available calculating time of the time slot
has been exceeded.
Time slot overflow
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

Operating Instructions
Counter-measure
- Check the converter outputs for earth fault
- Check the switch for "Safe OFF" on Compact
units
Fault in measured value sensing
Fault in power section (valve cannot block)
Fault on CU
- Check whether there is an external fault
- Check whether the cable to the
corresponding digital output is interrupted
- P575 (Src No ExtFault1)
- Check whether there is an external fault
- Check whether the cable to the
corresponding digital output is interrupted
- P576 (Src No ExtFault2)
Re-enter the parameter. The number of the
parameter concerned is indicated in fault value
r949.
Replace the control board (CUMC) or the unit
(Compact PUS).
Replace the control board (CUMC) or the unit
(Compact PLUS)
- Reduce pulse frequency
- Calculate individual blocks in a slower
sampling time
- Reduce pulse frequency (perhaps caused by
calculating time overflow)
- If fault re-occurs, replace the board/unit
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).
