Fault

number

Fault Counter-measure

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
