62: Up Command
Setting Function
62 Up Command
ON : Raises the frequency reference.
OFF : Holds the current frequency reference.
Note:
• If you only set the Up command or only set 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, oPE03 occurs:
–Up/Down command
–Accel/Decel Ramp Hold
–Reference sample hold
–Offset Frequency 1, 2, 3 addition
–Up/Down 2 Command
• You can use the Up/Down command when the keypad is in REMOTE mode and when b1-01 ≠ 0 [Freq. Ref. Sel. 1 ≠ Keypad].
• The Up/Down command does not function when you use Ext Ref 1/2 [H1-xx = 9] to switch to parameter b1-15 [Freq. Ref. Sel. 2].
When you input the Up command, the frequency reference increases. When you input the Down command, the
frequency reference decreases.
The Up and Down commands are more important than all other frequency references. When the Up/Down
command is enabled, 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 12.43 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 [FRef 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 FRef Hold Selection on page
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 [FRef Upper Limit].
Use an analog input or d2-02 [FRef Lower Limit] to set the lower limit value of the frequency reference. The
configurable values change when the setting for d4-10 [Up/Dw Frq Low 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 at the same time that 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.
