5. OPERATION
(2) Incremental value command positioning in absolute value command system
The position data set in the absolute value command system are used as incremental values in
positioning. Set the input signals and parameters as indicated below.

Here, Absolute value/incremental value selection RY(n+2)B is turned ON since the position data are
handled as incremental values.

Note. An external input signal is detected after a delay of the input filter setting time in parameter No. 2. Also, configure a sequence
that will change Point table selection earlier with consideration given to the output signal sequence from the controller and the
variations of signal changes due to the hardware.
