– The lower limit value of the frequency reference is set for both the analog input and d2-02
– The lower limit value of the analog input is higher than the setting value ofd2-02
Note:
Refer to "d4-10: Up/Down Freq Lower Limit Select" for details.
The following time chart 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 Freq Reference Retention Select [d4-01] is
enabled and disabled is shown below.
11: Down Command
■
Setting Value Function
11 Down Command
ON : Decreases the frequency reference.
OFF : Holds the current frequency reference.
Note:
• If only one of either the Up command or Down command has been set, oPE03 [Multi-Function Input Setting Err] will be detected.
• If two or more of the following functions have been allocated at the same time, oPE03 occurs.
–Up/Down command
–Accel/Decel Ramp Hold
–Reference Sample Hold
–Offset Frequency 1, 2, 3 addition
• The Up/Down command can be used when the keypad is in REMOTE mode or b1-01 ≠ 0 [Frequency Reference Selection 1 ≠
Keypad].
• The Up/Down command does not function when switching to parameter b1-15 [Frequency Reference Selection 2] using External
Reference 1/2 Selection [H1-xx = 2].
If the Up command is input, the frequency reference increases, and if Down command is input, the frequency
reference decreases.
Up and Down command has priority over all other frequency references. When the Up/Down command is
enabled, the following frequency references will be disregarded.
• Frequency reference from Keypad [b1-01 = 0]
• Frequency reference from Analog Input [b1-01 = 1]
