Shaft Rotation Direction
When you view the encoder from the shaft side, the shaft rotation is clockwise
(CW) or counterclockwise (CCW), as shown.

Mounting with a Solid Shaft
1. Be sure to select the proper size flexible coupling clamp to mate to the
encoder shaft, for example, 845–FC–*–*. See our website at
http://
ab.rockwellautomation.com/Motion-Control/Encoders
for encoder
accessories.
2. To determine the encoder mounting hole locations, use the dimension
drawings in the installation instructions (see “
Related Documentation”
on page
7
).
3. Slide the flexible coupling onto the shaft, but do not tighten the set
screws.
ATTENTION:
Do not rigidly connect the encoder shaft to the machine. A rigid
connection causes premature failure of the encoder or machine bearings.
Always use a flexible coupling.
