Chapter 3 Installation
2. Use the dimension drawings in the installation instructions to
determine the encoder mounting hole locations (see “Related
Documentation” on page 9).
3. Slide the flexible coupling onto the shaft, but do not tighten the set
screws.
4. Mount the encoder and tighten with three size M4 mounting
screws (not supplied).
5. Center the flexible coupling and tighten the set screws.
Mounting with a Hollow Shaft
1. Loosen the screw on the clamping ring with a 2.5-mm star driver.
2. Slide the encoder onto the mating shaft until the flex mount rests
on the machine surface.
3. Hold encoder firmly and mark the two mounting holes. (If
mounting holes already exist, proceed to Step 6.)
4. Slide the encoder off. Drill and tap the marked holes to accept M4
(or equivalent) screws.
5. Slide the encoder back onto the shaft until the flex mount rests on
the machine surface.
6. Attach the encoder with two M4 (or equivalent) screws.
7. Tighten the clamping ring screw to 1.1 Nm (10 in–lb).
Be sure the mating shaft is chamfered and grease-free.
ATTENTION: The encoder should slide freely onto the shaft; if not, do not force.
Check the shaft for interferences such as gouges, burrs, rust, or size.
Do not stress the flex mount while tightening the screws.
