Number / Fault Cause
F091 The rotating measurement takes longer than
programmed in a measured status. Possible
Mld Time causes:
Load torque too high
Load torque not uniform
Ramp-function generator disabled
F095 Due to entries for
- Permissible phase sequence
Mld n(set) - Maximum frequency,
- Minimum speed,
- Changeover frequency between V and I
model,
- Start of field-weakening frequency,
- Frequency suppression bandwidth
it was not possible to determine a permissible
frequency range for the rotating measurement.
F096 The rotating measurement was aborted due to
the inadmissible external intervention.
Mld abort
F097 The measured values for the nominal ramp-up
time when optimizing the controller deviate too
Mld meausred value greatly.
Cause: very unsteady load torque
F098 The rotating measurement has detected a fault
in the speed actual value signal. The fault
Mld Tachof 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)

Counter-measure
Eliminate the cause and re-start the
measurement (power up the converter again).
If it re-occurs, replace CU, or replace the unit
(Compact PLUS).
There must be a 10% frequency range which
lies above 1.1 times the changeover frequency
and below 0.9 times the start of field-
weakening frequency.
Possible counter-measures
- Permit both phase sequences
- Increase maximum frequency
- Reduce minimum speed,
- Reduce changeover frequency between the
V and I model.
- Reduce or remove the frequency
suppression bandwidth.
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)
If necessary, increase the torque limit values
to 100 percent
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
