.
ASR1 / ASR2 Switch Frequency
Default: 7.00
Settings 5.00–599.00Hz
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)
ASR 1 Integral Time
Default: 0.100
Settings 0.000–10.000 sec.
