Sets the hunting-prevention
gain.
Normally, there is no need to
change this setting.
If necessary, make the adjust-
ments as follows:
• 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 suppressed
and the motor may stall.
