Fault and Alarm Messages
Fault Fault description
No.
F103 Thy/Grnd Flt
Fault when conducting the
thyristor/ground-fault test
This fault message can only occur if the
thyristor/ground-fault test is activated with
parameters P353 / P354.
A software check is made to see whether
all thyristors have blocking capability,
whether they can be fired, and whether
there is a ground fault
Identification of the firing lines and the
associated thyristors should always be
made with the aid of the relevant wiring
diagram (see Section 3-5 "Power
terminals").

Possible causes
Countermeasures
- Thyristor defective
- Thyristor externally shorted
(e.g. by ground fault in grounded
system and ground fault in the
motor)
- Connection to DC link interrupted
(e.g. fuse blown)
Possible reasons for the thyristor
being defective:
- Interruption in the RC circuit
- Converter and compensation
control not optimized (excessive
current peaks)
- Cooling not guaranteed (e.g. fan
not running, ambient temperature
too high, to little air intake, heat
sink severely contaminated)
- Excessive voltage peaks in
supply system
- Ground fault
- Connection to DC link interrupted
(e.g. fuse blown)
- CUR module defect
- Firing pulse line to relevant
thyristor interrupted
- Ribbon cable X109 not correctly
plugged in or interrupted (and
ribbon cable X27 in the case of
power section connected in
parallel)
- Defect in electronics and/or
power interface module
- internal interruption on the gate
line in the thyristor module
- Connection to DC link interrupted
(e.g. fuse blown)
- As under 11 to 16
- As under 11 to 16
- Parameter P076 wrong
- As under 11 to 16
- As under 1 to 6
