• 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, if the Up/Down command is enabled, the
motor accelerates to the lower limit value of the analog input.
– 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
Note:
Refer to “d4-10 Up/Dw Frq Low Limit Select on page 600” for details.
Figure 12.80 shows an example of how Up/Down command operates. In this example, the lower limit value of the
frequency reference is set in d2-02. The time chart when FRef Hold Selection [d4-01] is enabled and disabled is
shown in Figure 12.80.

■ 63: Down Command
Setting Function Description
63 Down Command
Sets the command to decrease the drive frequency reference using a button. Users must also set Setting 62 [Up Command].
ON : Decreases 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
• To use the Up/Down command when the keypad is in REMOTE mode or b1-01 ≠ 0 [Freq. Ref. Sel. 1 ≠ Keypad]. If you use Ext Ref 1/2
[H1-xx = 9] to switch to parameter b1-15 [Freq. Ref. Sel. 2], the Up/Down command will not function.
When you input the Up command, the frequency reference will increase. When you input the Down command,
the frequency reference will decrease.
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]
