■
F: Not Used
Setting Value Function Description
F Not Used
Use this setting for unused terminals or to use terminals in through mode.
Through Mode uses the signal input to the terminal as a digital input for the upper sequence through a communication
option or MEMOBUS/Modbus communications. This input signal does not have an effect on drive operation.

10: Up Command
Setting Value Function Description
10 Up Command
Sets the command to use a push button switch to increase the drive frequency reference. You must also set Setting 11 [Down
Command] .
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 [Frequency Reference Selection 1 = Memobus/Modbus Communications, Option PCB]
– b1-02 ≠ 1 [Run Command Selection 1 ≠ Control Circuit Terminal]
–
Drive is in LOCAL mode
–
Set to b1-15 [Frequency Reference Selection 2] by use of H1-xx = 2 [MFDI Function Select = External Reference 1/2 Selection]
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 12.56 shows the Up and Down commands with their operation.

Up command (10) Down command (11)
OFF OFF Keeps the current frequency reference.
ON OFF Increases the frequency reference.
OFF ON Decreases the frequency reference.
ON ON Keeps the current frequency reference.
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.
