Chapter 4 Installation
6. Rotate the machine slowly and verify that the flexible coupling is not
deforming beyond specifications.
7. Align machine to its mechanical zero or home position.
8. Remove the screw cover on the back of the encoder and press the preset
push button to change the preset value to the current shaft position value.
(The factory preset value is zero.)
9. Replace the screw cover.
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).
8. Align machine to its mechanical zero or home position.
9. Remove the screw cover on the back of the encoder and press the preset
push button to change the preset value to the current shaft position value.
(The factory preset value is zero.)
10. Replace the screw cover.
Mechanical specifications
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.
