- (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

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.

SIMOVERT MASTERDRIVES Operating Instructions
Counter-measure
- Check the converter outputs for earth fault
- Check the switch for "SAFE STOP" on
Compact units
- Check the converter outputs for earth fault
- Check the switch for "SAFE STOP" on
Compact DC/DC units and chassis units with
the option "SAFE STOP"
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
- The technology functions Synchronization
(U953.33) and Positioning (U953.32) must not
be enabled at the same time.
