9−1−6. Scaling of analog output
The analog output for standard specifications is set between the minimum value and the
maximum value with the output of 0 to 2 000.
By changing the F−21 and F−22 , optional value can be decided.

F−21 sets the display when the minimum value is desired to output.
F−20 sets the display when the maximum value is desired to output.
例)F−21：Set as 1 000
F−22：Set as 5 000
When the display is 5 000, the maximum value outputs.
When the display is 1 000, the minimum value outputs.

Warning ● Take care that the setting on the F−22 doesn’t exceed the maximum
display value that has set in the Chapter 5.
● For the F−21, less value than the value to set for F−22 should be set.
If neglected, the correct output can’t be obtained.
