.
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, e.g., 845–FC–*–*. See encoder accessories in the
Sensors
catalog.
2.
Use the dimension drawings in the installation instructions to determine
the encoder mounting hole locations (see “Related documentation” on
page iii).
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; this will cause
premature failure of the encoder or machine bearings. Always use a flexible
coupling.
