ASR1 / ASR2 Switch Frequency
Default: 7.00
Settings
5.00–599.00 Hz
 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.

Zero-speed Bandwidth
Default: Read only
Settings
1–40 Hz
 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.
