– The lower limit value of the analog input is higher than the setting value of d2-02
Note:
Refer to d4-01: Freq Reference Hold Selection on page 234 for more information.
Figure 2.64 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 . Figure 2.64 shows the time chart when Freq Reference Retention Select [d4-01] is
enabled and disabled.

11: Down Command
Setting Value Function Description
11 Down Command
Sets the command to use a push button switch to decrease the drive frequency reference. You must also set Setting 10 [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
•
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]
