Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
The calculated armature circuit resistance is greater than 32.767 Ω, therefore P110 = 32,767 Ω has been set. All other
31
parameters have also been set. Possibly the calculated P111 and therefore also the current controller parameters P155
and P156 have been distorted by the limitation in P110 .
Possible cause:
•e.g. field supply from the armature terminals
r047 Index 002:
1
Fault has occurred during optimization run for current controller and precontrol for armature and field (selected by means of
P051=25)
2
Fault has occurred during optimization run for speed controller (selected through setting P051=26)
3
Fault has occurred during optimization run for field weakening (selected through setting P051=27)
4
Fault has occurred during internal offset adjustments (selected through P051=22)
5
Fault has occurred in optimization run for friction and moment of inertia compensation (selected through setting P051=28)
F051
No optimization run when permanent memory is disabled
(active in all operating states)
If P051.001 is set to 0 (write access to permanent memory disabled), it is not possible to execute an optimization run.
F052
Optimization run aborted as a result of external cause
(active in operating states of – –, I, II)
This fault message is activated when the converter ceases operating in the RUN state (state I, II or --) during an optimization run
(and thus in response to every FAULT) or if the EMERGENCY STOP or SHUTDOWN command is applied. The optimization run
is aborted. Only those parameters which had been fully optimized prior to activation of the fault message are altered .
When the STANDSTILL command is applied, this fault message is not activated if the optimization run for field weakening is
interrupted after the 1st field weakening measuring point has been recorded or, in the case of the optimization run for friction and
moment of inertia compensation, after the measuring point at 10% maximum speed has been determined. In these cases, the run
may be interrupted by STANDSTILL so as to be able to complete the run in several stages (by repeated restarts) for a limited
travel path.
Fault value:
1
Run was aborted because converter is no longer
operating in RUN mode
2
Run was aborted because EMERGENCY STOP
command was applied (speed controller setpoint =0)
3
Run was aborted because STANDSTILL command was
applied (ramp-function generator setpoint=0)
4
Operation has been aborted because P051 was changed
during the optimization run
5
Run was aborted because SWITCH-ON command was
not applied within 30 s of selection of optimization run
6
Operation has been aborted because the OPERATING
ENABLE command was not entered within 1 minute of
selection of the optimization run.
7
Operation has been aborted because converter was not
in operating state < o7.2 15 s after selection of the
optimization run with P051 = 25, 26, 27 or 28 (input of
OFF1 command may have been forgotten)

controller and precontrol for armature and field
(selected by means of P051=25)
i002=2 Fault has occurred during optimization run for speed
controller (selected through setting P051=26)
i002=3 Fault has occurred during optimization run for field
weakening (selected through setting P051=27)
