• When the Up 2 Command is active,
the drive accelerates the motor.
• When the Down 2 Command is
active, the drive decelerates the
motor.
• For all other statuses, the drive will
follow the frequency reference.

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).
• 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).

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.
■ 76: Down 2 Command
Setting Function Description
76 Down 2 Command
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 = 75 [Up 2 Command] together.
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/Down 2 Bias Upper Limit/Lower Limit].
• Refer to “d4: Frequency Ref Up/Down & Hold” for more information.
■ 77: ASR Gain (C5-03) Select
Setting Function Description
77 ASR Gain (C5-03)
Select
Sets the function to switch the ASR proportional gain set in C5-01 [ASR Proportional Gain 1] and
C5-03 [ASR Proportional Gain 1/2].
ON : C5-03
Switches the proportional gain to C5-03 [ASR Proportional Gain 2].
OFF : C5-01
Switches the proportional gain to C5-01 [ASR Proportional Gain 1].
Note:
Refer to “C5: Automatic Speed Regulator (ASR)” for more information.

Function Description
78 Analog TorqueRef
Polarity Invert
Sets the rotation direction of the external torque reference.
ON : External torque reference reverse direction
OFF : External torque reference forward direction
