ON : Increases the frequency reference.
OFF : Holds the current frequency reference.
Note:
• If you set only the Up command or only the Down command, the drive will detect oPE03 [Multi-Function Input Setting Err].
• If you set two or more of these functions at the same time, the drive will detect oPE03:
–Up/Down command
–Accel/Decel Ramp Hold
–Reference Sample Hold
–Offset Frequency 1, 2, 3 addition
–Up/Down 2 Command
• The Up/Down command does not function in these conditions:
– b1-01 = 2, 3 [Freq. Ref. Sel. 1 = Modbus, Option PCB]
– b1-02 ≠ 1 [Run Comm. Sel 1 ≠ Analog Input]
– Drive is in LOCAL mode
– Set to b1-15 [Freq. Ref. Sel. 2] by use of H1-xx = 9 [MFDI Function Select = Ext Ref 1/2]
When you enter the UP command, the frequency reference increases. When you enter the Down command, the
frequency reference decreases.
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]
Table 12.41 shows the Up and Down commands with their operation.

Combine Frequency Reference Hold Functions and Up/Down Commands
• When you clear the Run command or when d4-01 = 0 [Freq Reference Hold Selection = Disabled], and you
restart the drive, the Up/Down command resets to 0.
• When d4-01 = 1 [Enabled], the drive saves the frequency reference set during the Up/Down command. When
you cycle the Run command or restart the drive, the drive saves the frequency reference value and restarts the
motor at this frequency value. After you clear the Run command, activate the terminal set for the Up command
or Down command to set the saved reference value to 0.
Note:
Refer to "d4-01 [Freq Reference Hold Selection]" for more information.
Combine Upper/Lower Limits of the Frequency Reference and the Up/Down Commands
Set the upper limit value of the frequency reference to d2-01 [Frequency Reference Upper Limit].
Use an analog input or d2-02 [Frequency Reference Lower Limit] to set the lower limit value of the frequency
reference. The configurable values change when the setting for d4-10 [Up/Down Freq Lower Limit Select]
changes. When you input a Run command, these are the lower limits of the frequency reference:
• When the lower limit of the frequency reference is set only for d2-02, the drive accelerates the motor to the
lower limit value of the frequency reference when you input the Run command.
• When the lower limit of the frequency reference is set only for analog input, the drive accelerates the motor to
the lower limit value of the frequency reference when the Run command, and Up command or Down command
for the drive is enabled. When only the Run command is enabled, the motor does not start.
• When these conditions occur, the drive accelerates the motor to the d2-02 setting value when the Run command
is input. When the motor accelerates to the setting value of d2-02, the motor accelerates to the lower limit value
of the analog input when you enable the Up/Down command.
– The lower limit value of the frequency reference is set for the analog input and d2-02
– The lower limit value of the analog input is higher than the setting value of d2-02
