12.7 H: TERMINALS
684 SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
■ 65: Up2 Command
Setting Function Description
65 Up2 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 = 66 [Dw2 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. Table 12.44 gives information about the relation between operation of the Up/Down
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].
• Refer to “d4: FREQUENCY UP/DOWN” for more information.

• 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.

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.

• 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.

• 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 FRef 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.
