F096
Mld abort
The rotating measurement was aborted due to
the inadmissible external intervention.
The fault value in r949 defines the type of
intervention:
4 Setpoint inhibit
5 Changeover, setpoint channel
8 Unexpected change in the converter status
12 Motor data set changeover (for function
selection "Compl. Mot ID")
13 Changeover to slave drive
14 Motor data set changeover to data set with
v/f_charac
15 Controller inhibit is set
16 Ramp-function generator is disabled
17 Selection "Tacho test" for F controller
18 Ramp-function generator stopped
Eliminate cause
22 Inverter inhibit:
Check inverter release (P561)
F097
Mld meausred value
The measured values for the nominal ramp-up
time when optimizing the controller deviate too
greatly.
Cause: very unsteady load torque
If necessary, increase the torque limit values
to 100 percent
F098
Mld Tachof
The rotating measurement has detected a fault
in the speed actual value signal. The fault
value defines the type of fault.
The fault measurement may have been
erroneously generated if the drive speed is
externally forced (e.g. completely locked drive
generates the "no signal" message)
The fault value in r949 defines the type of
intervention
4 No speed signal present
5 Sign of the signal is incorrect
6 A track signal is missing
7 Incorrect gain
8 Incorrect pulse number

GRND Init
During the ground fault test, a current not
equal to zero has been measured, or an UCE
or overcurrent monitoring has responded,
although no value has yet been triggered.
The cause of the fault can be read out from
r376 "GrdFltTestResult".
Check the converter output for short-circuit or
ground fault
(-X2:U2, V2, W2 - including motor).
Check that the CU is inserted correctly.
Sizes 1 and 2:
- Check the transistor modules on the PEU
board -A23 for short-circuit.
Size 3 and 4:
- Check the transistor modules -A100, -A200,
-A300 for short-circuit
