Anti-hunting regulator P gain (FUN_59)
Higher AHR (anti-hunting regulator) proportional gain enhances the
responsiveness of the system and provides good hunting prevention. However,
unstable current conditions may result if you set it too high.
Anti-hunting regulator start/end frequency (FUN_60/FUN_61)
FUN_60 and 61 are used to define the minimum and maximum frequency
where the AHR function will operate.
6.5.10 Setting the operation speed and input voltage
for battery operation
Battery operation is an emergency measures to continue the inverter operation
using the external battery when the power source is interrupted due to blackout
or other reasons.

Battery Run
FUN_67 and FUN_68 are displayed only when one of the multifunction inputs
DIO_01 –07 is set for “Battery Run”.
FUN_67 is used to define the operation speed during the emergency operation
on battery power.
FUN_68 is used to define the battery input voltage during the emergency
operation on battery power.
To enable the inverter operation on battery, turn on the signal at the multifunction
input that is set for the battery operation (“Battery Run”). The inverter runs on
battery based on the speed set at FUN_67, and the low voltage fault trip level is
