0 • When the Up 2 Command is active,
the drive accelerates the motor
(increases the bias value).
• When the Down 2 Command is
active, the drive decelerates the
motor (decreases the bias value)
• When the Up 2 Command and Down
2 Command are not active and when
the Up 2 Command and Down 2
Command are active, the drive holds
the output frequency (holds the bias
value).
• When the frequency changes, it will
reset the bias.
• For all other statuses, the drive will
follow the frequency reference.
Not stored.

When the bias value and frequency
reference are constant for 5 seconds
after the frequency reference hold
starts, the drive will add the bias value
to the enabled frequency reference,
then reset.

0 • When the Up 2 Command is active,
the drive accelerates the motor to
“Freq Reference + d4-03” (the bias
value will increase to the value set in
d4-03).
• When the Down 2 Command is
active, the drive decelerates the
motor to “Freq Reference - d4-03”
(the bias value will decrease to the
value set in d4-03).
• When the Up 2 Command and Down
2 Command are not active and when
the Up 2 Command and Down 2
Command are active, the drive holds
the output frequency (holds the bias
value).
• When the frequency changes, it will
reset the bias.
• For all other statuses, the drive will
follow the frequency reference.

0 • When the Up 2 Command is active,
the drive accelerates the motor
(increases the bias value).
• When the Down 2 Command is
active, the drive decelerates the
motor (decreases the bias value).
• When the Up 2 Command and Down
2 Command are not active and when
the Up 2 Command and Down 2
Command are active, the drive holds
the output frequency (holds the bias
value).
• During acceleration or deceleration,
when the frequency reference
increases or decreases more than d4-
07 [Analog Freq Ref Fluctuate
Limit], the drive holds the bias value
until the output frequency and the
actual frequency reference agree
(speed agreement).
Not stored.

When the bias value is constant for 5
seconds after the frequency reference
hold starts, the drive will store the bias
value in d4-06. You cannot rewrite the
frequency reference is not possible.
The drive will store only the bias
value.
