0: Bias value is held if no input Up 2 or Down 2 is active.
1: When the Up 2 reference and Down 2 reference are both on
or both off, the applied bias becomes 0. The specified accel/
decel times are used for acceleration or deceleration.

All Modes
The Up/Down 2 bias value is saved in d4-06 when the
frequency reference is not input by the digital operator. Set as
a percentage of the maximum output frequency.

All Modes
Limits how much the frequency reference is allowed to change
while an input terminal set for Up 2 or Down 2 is enabled. If
the frequency reference changes for more than the set value,
then the bias value is held and the drive accelerates or
decelerates to the frequency reference. Set as a percentage of
the maximum output frequency.
