CON-14 AHR P-Gain
Increasing AHR proportional gain improves responsiveness of the
anti-hunting regulation. However, current oscillation may result if AHR
proportional gain is set too high.
CON-15 AHR Low Freq
CON-16 AHR High Freq
Sets the lower limit frequency (CON-15) and the maxim limit
frequency (CON-16) for anti-hunting regulation.
