Datum Setting
The datum setting procedure assigns a display value to a
known position. With the ND 200 series, you can set two
separate datum points.
There are several ways to set the datum:
• Enter a numerical value, or
• Transfer a value from an operating parameter
(see P79, P80), or
• By external signal
Select datum 1 or 2.
Enter a numerical value (here, 5).
SET starts blinking.

Confirm the entered numerical value.
You can switch between datums 1 and 2 as desired. Datum 2
can be used, for example, for working with incremental dimen-
sions.
When you switch back to datum 1, the display unit resumes
display of the encoder's actual position.
