66: Dw2 Command
Setting Function
66 Dw2 Command
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.
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].
• Refer to "d4: FREQUENCY UP/DOWN" for more information.
■
67: SpeedSearch Fmax
Setting Function
67 SpeedSearch Fmax
When the terminal is turned ON for b3-24 = 2 [SpSrch Method Selection = Current Det2], the drive starts speed
search from the maximum output frequency.
Note:
• The drive will detect oPE03 [Multi-Function Input Setting Err] when H1-xx = 67 and 68 are set at the same time.
• Refer to "b3: SPEED SEARCH" for more information.
■
68: SpeedSearch Fref
Setting Function
68 SpeedSearch Fref
When the terminal is turned ON for b3-24 = 2 [SpSrch Method Selection = Current Det2], the drive starts speed
search from the frequency reference.
Note:
• The drive will detect oPE03 [Multi-Function Input Setting Err] when H1-xx = 67 and 68 are set at the same time.
• Refer to "b3: SPEED SEARCH" for more information.

d4-05 d4-01
• When the Up 2 Command is active, the drive
accelerates the motor.
• When the Down 2 Command is active, the
0 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 "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
> 0 -
set in d4-03).

• During acceleration or deceleration, when the
frequency reference increases or decreases
more than d4-07 [Analog FRef Fluctuate
Limit], the drive holds the bias value until the
output frequency and the actual frequency
reference agree (speed agreement).
V/f CL-V/f OLV CLV
Sets the function to increase the frequency reference bias value to accelerate the motor when the terminal is activated. Set this
function and H1-xx = 65 [Up2 Command] together.
V/f CL-V/f OLV CLV
Sets the function to start speed search using an external reference although b3-01 = 0 [SpSrch@Start Selection = Disabled].
V/f CL-V/f OLV CLV
Sets the function to start speed search using an external reference although b3-01 = 0 [SpSrch@Start Selection = Disabled].
V/f CL-V/f OLV CLV
Sets the command to disable PID control when b5-01 = 1 [PID Enable = Enabled].

Storing the Frequency Reference or
Frequency Bias
Not stored.
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.
