76: Down 2 Command
Setting Value Function
76 Down 2 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 you use this function, set the optimal bias limit values with d4-08 and d4-09 [Up/Down 2 Bias Upper Limit/Lower Limit].
• Refer to d4: Frequency Ref Up/Down & Hold on page 725

77: ASR Gain (C5-03) Select
Setting Value Function
77 ASR Gain (C5-03) Select
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.

• 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 active or not active, the drive
0 0
holds the output frequency (holds the bias
1
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).
V/f CL-V/f OLV CLV
Sets the function to decrease the frequency reference bias value to decelerate the motor when the terminal is activated. Set this
function and H1-xx = 75 [Up 2 Command] together.
V/f CL-V/f OLV CLV
Sets the function to switch the ASR proportional gain to C5-01 [ASR Proportional Gain 1] or C5-03 [ASR Proportional Gain
2].
V/f CL-V/f OLV CLV
Sets the rotation direction of the external torque reference.

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.
