Number / Fault Cause Counter-measure
F107
MLd = 0
A fault has occurred during the test pulse
measurement
Read out fault value from r949. The figures of
the grey shaded areas indicate which fault has
occurred.
O O X X xx = 01: Both current actual values
remain 0
xx = 02: Motor-converter cable
phase U interrupted
xx = 03: Motor converter phase V
interrupted
xx = 04: Motor-converter phase W
interrupted
xx = 05: Current actual value I1
remains 0
xx = 06: Current actual value I3
remains 0
xx = 07: Valve U+ does not trigger
xx = 08: Valve U- does not trigger
xx = 09: Valve V+ does not trigger
xx = 10: Valve V- does not trigger
xx = 11: Valve W+ does not trigger
xx = 12: Valve W- does not trigger
xx = 13: Sign I1 incorrect
xx = 14: Sign I3 incorrect
xx = 15: Sign I1 and I3 incorrect
xx = 16: Sign I1 confused with I3
xx = 17: I1 confused with I3 and
both currents have an
incorrect sign
The digit of the xth digit indicates where the
fault has occurred.
X O O O x = 0 = Single converter
x = 1 = Inverter 1
x = 2 = Inverter 2
x = 3 = Inverters 1 and 2
Check that all 3 motor feeder cables and the
motor windings do not have any interruption.
Check the connection between the current
converter and the electronics and check the
current converter itself. Check the correct input
of the rating plate data for the motor data set
valid during the measurement.
F108
Mld Unsym
During the DC measurement, the
measurement results for the individual phases
differ significantly. The fault value indicates
which quantity(ies) is(are) concerned and in
which phase the greatest deviation occurred.
Read out fault value from r949. The digit of the
xth position indicates;
O O O X Transverse voltage too high
x = 1 = phase R
x = 2 = phase S
x = 3 = phase T
O O X O Dev. stator resistance
(1, 2, 3 as above)
X O O O Dev. dead-time compensation
(1, 2, 3 as above)
X O O O O Dev. valve voltage
(1, 2, 3 as above)
The motor, power section or actual-value
sensing are significantly non-symmetrical.
F109
Mld R(L)
The rotor resistance determined during DC
measurement deviates too significantly from
the value which was calculated by the
automatic parameterization from the rated slip.
- Incorrect input of rated speed or rated
frequency
- Pole pair number incorrect
