3. Using a transfer punch, locate the encoder mounting screw positions.
4. Drill and tap the required #8-32 X 1/2” (minimum) mounting holes.
5. Mount the encoder using the #8-32 screws provided. Tighten the screws just
enough to hold the encoder in place, and still be loose enough to make alignment
adjustments.
6. Mount an indicator on the knee and adjust the probe to measure the position of the
top of the encoder.
7. Slowly move the X-axis through its entire range of travel while observing the
indicator. The top of the encoder should be parallel to the X axis movement of the
table (within 0.002”) over its entire range of travel.
NOTE: If the encoder is not properly aligned the reader head will not read correctly.
8. Loosen the screws at one end of the encoder, and adjust the position up or down as
required for alignment. The play in the mounting holes should provide enough
movement.
9. Once aligned, fully tighten the mounting screws.
10. Recheck the alignment.
Mounting and Aligning X Axis Reader Head
1. Move the table to the dead stop position at one end of its range of travel.
2. Slide the reader head as far as it will go in the same direction.
