ASR Proportional Gain 1
Sets the gain to adjust ASR response.
Note:
If A1-02 = 0 [Control Method Selection = V/f], you must set H6-01 = 3 [Terminal RP Pulse
Train Function = Speed Feedback (V/F Control)] to enable this parameter.

RUN
ASR Integral Time 1
Sets the ASR integral time.
Note:
If A1-02 = 0 [Control Method Selection = V/f], you must set H6-01 = 3 [Terminal RP Pulse
