(1) Set ASR Calculation Selection F2-02 = 1: Bandwidth.
(2) Adjust the ASR high-speed and low-speed area through Pr. F2-03 ASR High/ Low
BW Switch FREQ.
(3) If the starting torque is insufficient or the speed response is slow, increase setting
for Pr. F2-04 ASR Zero-Speed BW.
(4) If the speed in the low-speed area oscillates at low frequency or responds slowly,
increase setting for Pr. F2-05 ASR Low-Speed BW.
(5) If the speed in the low-speed area oscillates at high frequency, decrease setting for
Pr. F2-05 ASR Low-Speed BW.
(6) If the speed in the high-speed area oscillates at low frequency or responds slowly,
increase setting for Pr. F2-06 ASR High-Speed BW.
(7) If the speed in the high-speed area oscillates at high frequency, decrease setting for
Pr. F2-06 ASR High-Speed BW.
B. Adjust ASR gain
(1) Set ASR Calculation Selection F2-02 = 0: Gain.
(2) Adjust the ASR high-speed and low-speed area through Pr. F2-03 ASR High/ Low
BW Switch FREQ.
(3) If the starting torque is insufficient or the speed response is slow, increase setting
for Pr. F2-07 ASR Zero-Speed Gain or decrease setting for Pr. F2-08 ASR Zero-
Speed Integral Time.
(4) If the speed in the low-speed area oscillates at low frequency or responds slowly,
increase setting for Pr. F2-09 ASR Low-Speed Gain or decrease setting for Pr. F2-
10 ASR Low-Speed Integral Time.
(5) If the speed in the low-speed area oscillates at high frequency, decrease setting for
Pr. F2-09 ASR Low-Speed Gain or increase setting for Pr. F2-10 ASR Low-Speed
Integral Time.
(6) If the speed in the high-speed area oscillates at low frequency or responds slowly,
increase setting for Pr. F2-11 ASR High-Speed Gain or decrease setting for Pr. F2-
12 ASR High-Speed Integral Time.
(7) If the speed in the high-speed area oscillates at high frequency, decrease setting for
Pr. F2-11 ASR High-Speed Gain or increase setting for Pr. F2-12 ASR High-Speed
Integral Time.
7. Adjust speed observer filter bandwidth.
(1) If the speed response is too slow or the frequency command cannot be tracked, increase
setting for Pr. F1-03 Speed Observer Filter BW.
(2) If the output frequency fluctuates too much, decrease setting for Pr. F1-03 Speed
Observer Filter BW.
8. Test loading capacity at low-frequency.
(1) If the loading capacity at low-frequency is insufficient, increase setting for Pr. F1-08
Observer Low Speed Gain.
(2) If the low-frequency current is unstable or the output frequency fluctuates too much,
decrease setting for Pr. F1-08 Observer Low Speed Gain.
