10: Up Command
Setting Value Function Description
10 Up Command
You must also set Setting 11 [Down Command] . Sets the command to use a push button switch to decrease the drive frequency
reference
ON : Increases the frequency reference.
OFF : Holds the current frequency reference.
Note:
• If only one of either the Up command or Down command has been set,
oPE03 [Multi-Function Input Setting Err]
will be detected.
• If two or more of the following functions have been allocated at the same time, oPE03 occurs.
– Up/Down command
– Accel/Decel Ramp Hold
– Reference Sample Hold
– Offset Frequency 1, 2, 3 addition
• The Up/Down command can be used when the keypad is in REMOTE mode or b1-01 ≠ 0 [Frequency Reference Selection 1 ≠
Keypad] .
• The Up/Down command does not function when switching to parameter b1-15 [Frequency Reference Selection 2] using External
Reference 1/2 Selection [H1-xx = 2] .
If the Up command is input, the frequency reference increases, and if Down command is input, the frequency
reference decreases.
Up and Down command has priority over all other frequency references. When the Up/Down command is
enabled, the following frequency references will be disregarded.
• Frequency reference from Keypad [b1-01 = 0]
• Frequency reference from Analog Input [b1-01 = 1]
The table below shows the Up and Down commands with their corresponding operation.

Up Command (10) Down Command (11)
OFF OFF Holds the current frequency reference.
ON OFF Increases the frequency reference.
OFF ON Decreases the frequency reference.
ON ON Holds the current frequency reference.
Combine Frequency Reference Hold Functions and Up/Down Commands
• When the Run command is cleared, or when the drive is restarted when
d4-01 = 0 [Freq Reference Retention
Function = Disabled] , the Up/Down command will reset to 0.
• When parameter d4-01 = 1 [Enabled] , the drive saves the frequency reference set during the Up/Down
command. If the Run command is cycled or the drive is restarted, the drive stores the frequency reference value
and restarts the motor at this frequency value. After the Run command is cleared, turn ON the terminal set for
the Up command or Down command to reset the stored reference value to 0.
Note:
Refer to “ d4-01: Freq Reference Hold Selection ” for details.
Combining 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] .
The lower limit value of the frequency reference can be set with analog input or in
d2-02 [Frequency Reference
Lower Limit] . The configurable values differ depending on the setting for d4-10 [Up/Down Freq Lower Limit
Select] . When the Run command is executed, the lower limits of the frequency reference are as follows.
• When the lower limit of the frequency reference is set only for d2-02 , the drive accelerates the motor up to the
lower limit value of the frequency reference at the same time the Run command is input.
• When the lower limit of the frequency reference is set only for analog input, the drive accelerates the motor up
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 the following conditions are present, the drive accelerates the motor up to d2-02 setting value if the Run
command is input. When the motor has accelerated to the setting value of d2-02 , if the Up/Down command is
enabled, the motor accelerates to the lower limit value of the analog input.
