Unit of induction motor system inertia is kg-cm

The base value for PM system inertia is set by Pr.05-38 and the unit is in kg-cm

ASR1 / ASR2 Switch Frequency

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

ASR1 Low-speed Bandwidth

ASR2 High-speed Bandwidth

Zero-speed Bandwidth

 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 response you. Pr. 11-02 is the switch frequency for the low-speed / high-speed

 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.

5.00–599.00Hz
