One−time setting of X position
If slipping and non−integer pulse lengths can be ruled out, the X position must only be set once.
Procedure:
l Set the master drive (machine) to the position applied to the input CDATA−TP−POS.
– CDATA−X−TP/E5 = LOW
l X position is accepted with a LOW−HIGH edge at CDATA−X−TP.

The direction" indicates the increase of the integrator (output CDATA−XPOS):
– With positive input values at CDATA−DFIN, the integrator runs from 0 to its clock pulse length
(X cycle).
– With negative input values at CDATA−DFIN, the integrator runs from the clock pulse length (X
cycle) to 0.

Change of direction of rotation for connection at input CDATA−DFIN
(see also chapter 3.2.3.3)
This function is only available for the internal X integrator (C1332 = 0).
The direction can be reversed via code C1314 (see Fig. 3−9).

Stop!
The input CDATA−XOFFS is not affected by a reversal of the direction under C1314!
