When you activate the terminal set for Up2 Command, the bias will increase. When you activate the terminal set
for Down 2 Command, the bias will decrease. When you activate or deactivate the two commands, the drive will
hold the frequency reference.
2 Command and d4-01, d4-03, d4-05.
Note:
• When using this function, set the optimal bias limit value with d4-08 and d4-09 [Up/Dw2 Bias Upper Limit and Up/Dw2 Bias Lower
Limit].

• When the Up 2 Command is active, the drive
0
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
0
Command and Down 2 Command are active,
1
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.
• When the Up 2 Command is active, the drive
accelerates the motor.
• When the Down 2 Command is active, the
1 -
drive decelerates the motor.
• For all other statuses, the drive will follow the
frequency reference.
• When the Up 2 Command is active, the drive
0
accelerates the motor to "Frequency 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 "Frequency
Reference - d4-03" (the bias value will decrease
to the value set in d4-03).
• When the Up 2 Command and Down 2
> 0 -
Command are not active and when the Up 2
1
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.
• When the Up 2 Command is active, the drive
0
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
0 0
Command and Down 2 Command are active,
1
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, the drive holds the bias value
until the output frequency and the actual
frequency reference agree (speed agreement).
• When the Up 2 Command is active, the drive
accelerates the motor (increases the bias value).
• When the Down 2 Command is active, the
0 1 - drive decelerates the motor (decreases the bias
value)
• For all other statuses, the drive will follow the
frequency reference.
• When the Up 2 Command is active, the drive
0
accelerates the motor to "Frequency 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 "Frequency
> 0 - Reference - d4-03" (the bias value will decrease
to the value set in d4-03).

• During acceleration or deceleration, when the
frequency reference increases or decreases
more than d4-07, the drive holds the bias value
until the output frequency and the actual
frequency reference agree (speed agreement).
Storing the Frequency Reference or
Operation
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.
