.

ASR1 / ASR2 Switch Frequency
Default: 7.0
Settings 5.0–1500.0 Hz
 The upper limit is the same as the maximum operation frequency for Pr.01-00.
 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, the high-speed range is too
narrow.

ASR1 Low-speed Bandwidth
Default: 10
Settings 1–40Hz (IM) / 1–100Hz (PM)

ASR2 High-speed Bandwidth
Default: 10
Settings 1–40Hz (IM) / 1–100Hz (PM)

Zero-speed Bandwidth
Default: 10
Settings 1–40Hz (IM) / 1–100Hz (PM)
 After estimating inertia and setting Pr.11-00 bit0=1 (auto-tuning), you can adjust Pr.11-03,
Pr.11-04 and Pr.11-05 separately according to the speed response. The larger the setting value,
the faster the response. Pr.11-02 is the switch frequency for the low-speed / high-speed
bandwidth.
 The position control pulse command (MIx=37) and P2P position control Kp gain can adjust
Pr.11-05. The higher the value, the lower the steady-state error.

ASR 1 Gain
Default: 10
Settings 0–40 Hz (IM) / 1–100Hz (PM)
