Per-unit of System Inertia
Settings
 Decrease the setting value if there is high frequency spur which occurs on Iq current
command of ASR. If the response of sudden load is too slow, then increase the setting
value.
ASR1/ASR2 Switch Frequency

Settings
 Low-speed/ high speed switch point of ASR in FOC area. This provides higher response in
high speed area and lower response in low speed area to meet customers demand. It is
suggested that the switch point should >Pr10-39.
 If the setting value is too low, it will not cover Pr10-39. If it's too high, the range of high speed
will be too narrow.

 After estimating inertia and set Pr.11-00 to bit 0=1 (auto tuning), user can adjust
parameters Pr.11-03, 11-04 and 11-05 separately by speed response. The larger number
you set, the faster response you will get. Pr.11-02 is the switch frequency for
low-speed/high-speed bandwidth.
 Position control pulse command (MIx=37) and P2P position control Kp gain can adjust
Pr11-05. The higher the value, the lower the steady-state error.
