ASR1／ASR2 switch frequency
5.00 to 599.00 Hz
7.00
Sets the low-speed and high-speed ASR switching point in the FOC area. Provides flexibility to meet two needs:
in the high-speed region of the estimator switch point it has a high response, and in the low-speed region of the
estimator switch point it has a lower response. The recommended switching point is higher than Pr.10-39.
A low setting does not cover Pr.10-39. If the setting is too high, high-speed range is too narrow.

After estimating the inertia and setting Pr.11-00 bit 0 = 1 (auto-tuning), you can adjust Pr.11-03, 11-04 and 11-05
separately by speed response. The larger the setting value, the faster the response. Pr.11-02 is the switch
frequency between the low-speed/high-speed bandwidth.

This function enables when Pr.11-00 bit 0 = 1.
Increase the setting for Pr.11-12 to reduce the command tracking difference and improve the speed response. Use
this function for speed tracking applications.
Set Pr.11-01 correctly to get excellent improvement of the speed response.
