Step 8 - Setting the motor in “Flux Vect OL” mode (sensorless)
Menu 04 DRIVE CONFIG, parameter 04.2 Regulation mode, PAR: 552,
set = [1] Flux vector OL.
Test with no load applied to the motor
1 Set the value of PAR 2308 OverFlux perc to 120%.
2. Set the value of PAR 2312 OverFlux spd thr to approximately 25% of the
rated speed.
3. Close the Enable contact (terminals S3 – 7).
4. Close the FR forward src contact (PAR 1042), terminals S3 – 8. The drive
starts magnetising the motor.
5. Using the potentiometer, gradually increase the reference signal until reaching
the maximum speed.
6. Open the FR forward src contact (PAR 1042), terminals S3 – 8, until reach-
ing the minimum set speed requested by the application.
7. Check that the ramp is linear and, once the set value has been reached, that
the minimum speed remains stable.
If the ramp is not linear and the minimum speed is not stable, reduce the value
of PAR 2306 Flux observe gain OL in steps of 5.
Examples of values for PAR 2306 with standard 4-pole motors
100 For motor power ratings up to 15 kW
40-50 For motor power ratings of 45-55 kW
20-30 For motor power ratings of more than 132 kW
8. To save the new parameter settings, so that they are maintained also after
power-off, proceed as follows:

Test with rated load applied to the motor
1. Close the Enable contact (terminals S3 – 7).
2. Close the FR forward src contact (PAR 1042), terminals S3 – 8. The drive
starts magnetising the motor.
3. Using the potentiometer, gradually increase the reference signal until reaching
the maximum speed.
4. Open the FR forward src contact (PAR 1042), terminals S3 – 8, until reach-
ing the minimum set speed requested by the application.
- if current overload conditions occur at the minimum speed,
- if the current exceeds the rated current value setting,
- if the motor shaft is blocked at zero speed,
reduce the value set in PAR 2306 Flux observe gain OL in steps of 5 until
reaching the best working condition with no overload.
5. To save, repeat step 6.
