F095 MId n(set)
Due to entries for
• Permissible phase sequence
• 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.
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.
F096 MId abort
The rotating measurement was aborted due
to 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
F097 MId measured 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
