This function is used to prevent the hunting of a V/F controlled fan or motor caused by current
distortion or oscillation due to mechanical resonance or other reasons. You can set the hunting
prevention function (CON-90) to prevent current hunting.
CON-91 AHR P-Gain : Increasing AHR proportional gain improves the responsiveness of the
anti-hunting regulation. However, current oscillation may result if AHR proportional gain is set
too high.
8.42 Fire Mode
This function is used to allow the inverter to ignore minor faults during emergency situations,
such as fire, and provides continuous operation to protect other systems, such as ventilation
fans. When fire mode is activated, the inverter operates continuously based on the set
frequency and direction.
