Set the integral gain 2 of a separate
controller.
YES
Cn.25

10 to
999ms Sensorless speed controller integral gain 0. YES
Cn.26
[18]
Flux estimator
proportional
gain
(*)
1 to
200% Sensorless vector control requires the rotor
flux estimator. Use these parameters to
adjust flux estimator gain
YES
Cn.27

Flux estimator
integral gain
(*)
1 to
200%
YES
Cn.28
[18]
Speed
estimator
proportional
gain 1
(*)
0 to
32767
Adjusts speed estimator gain for sensorless
vector control:
•
At low speed (10Hz or lower), increase
the value of Cn.29 by increments of 5.
•
At mid speed (30 Hz or higher), increase
the value of Cn.28 by increments of 500.
If the parameter setting is too extreme,
over current trip may occur at low speed.
YES

proportional
gain
(*)
10 to
1000 Adjusts the P and I gains of the sensorless
current controller.
If the value of Cn.10 is high, an overcurrent
trip at start can occur. In this case, reduce
the value of Cn.31 by decrements of 10.
YES
