12.7 H: TERMINALS
SIEPYEUOQ2A01G AC Drive Q2A Technical Manual 705
When you input the Up command, the frequency reference will increase. When you input the Down command,
the frequency reference will decrease.
The Up and Down commands have priority over all other frequency references. When you enable the Up/Down
command, the drive will ignore these frequency references:
• Frequency reference from Keypad [b1-01 = 0]
• Frequency reference from Analog Input [b1-01 = 1]
• Frequency reference from Pulse Train Input [b1-01 = 4]
■ 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 12.43 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.
