5.3.5 Mechanical adjustment the incremental encoder
The incremental encoder on the X- and Y-Axis must be adjust of a distance of 0,4 mm +/- 0,1 mm
to the incremental scale.
Please Note:
For adjust the distance use a plastic feeler gauge of 0,4 mm.
After this adjustment of the incremental encoder you have to check the zero pulse and track sig-
nals (see chapter Tracksignals and Zeropulse).

5.4 Track signals and Zero pulse
5.4.1 Check the zero pulse signal
The zero pulse on the incremental scale must be recognize from the incremental encoder secure
and perfectly. To check the zero pulse you can check the analog or digital zero pulse.
If the zero pulse is not recognize correctly, the axis will reference to a spurious peak. Placement
offsets will be the result.
On the incremental measurement you can‘t make any electrical adjustments.
