23 MOT STALL
Motor stalled
While starting the motor
the
current exceeded
the value of parameter
[P 28.17]
for a time
longer than parameter
[P 28.15]
and
the
speed feedback value was below parameter
[P 28.16]
.
Check: - Motor stalled?
- Load changed during start?
- Correct field current?
- Current/torque limitation;
- Parameter settings
[P 15.08]
.

28 ARM OVOLT
Armature (DC circuit) overvoltage
Check: - Setting of param.
[P 28.22]
suitable
for the system configuration?
- Setting of field current and actual
value as well as the complete
field supply (FIELD EXCITER);
- Was the motor accelerated by
the load?
- Speed scaling;
- Armature voltage feedback;
- Connections between SDCS-
CON-2 and SDCS-PIN boards;
- Coding of voltage evaluation on
SDCS-PIN-xx board.

or/ and
[P 40.02]
Check: - Is the mains voltage within the
admissible tolerance?
- Did the mains contactor close
and open?
- Voltage scaling via parameter
[P 42.06]
rated line voltage
correct?
- Connections between SDCS-
CON-2 and SDCS-PIN-xx boards;
- Coding of voltage measurement
on SDCS-PIN-xx board.
