The hunting-prevention
function suppresses hunting
when the motor is operating
with a light load.
This function is enabled in
V/f control method only.
If high response is to be
given priority over vibration
suppression, disable the
hunting-prevention function.
Set the hunting-prevention
gain multiplication factor.
Normally, there is no need to
make this setting.
Make the adjustments as fol-
lows:
• If vibration occurs with
light load, increase the set-
ting.
• If the motor stalls, reduce
the setting.
If the setting is too large, the
voltage will be too sup-
pressed and the motor may
stall.
