2.8 H: Terminal Functions
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
• The Up/Down command does not function in these conditions:
–b1-01 = 2, 3 [Frequency Reference Selection 1 = Serial Communications, Option PCB]
–b1-02 ≠ 1 [Run Command Selection 1 ≠ Digital Input]
–Drive is in HAND mode
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]
Table 2.48 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
