2.1.2 Thru-Shaft Pulse Wheel Installation

Rotate the pulsewheel so the stamped letter "Z" or "This Side Out" is visible, away from the motor. Slide the pulse

wheel onto the motor shaft. Push the wheel along the shaft until the edge of the pulsewheel is flush with the machined

recess in the encoder frame. See Figure 4. It is recommended to use a straight edge for this purpose. For best results,

align the two surfaces to within ±0.010 inch. The purpose of this step is to properly center the pulsewheel under the

sensor.

a. Clamp Style

With the pulsewheel properly aligned, use a 9/64 inch hex wrench to tighten the #8 socket head cap screw

in the pulsewheel clamp to a nominal 30 inch-pounds.

b. Set Screw Style

With the pulsewheel properly aligned, use a 9/64 inch hex wrench to tighten (2) 8-32 UNC set screws with

nominal torque.

3. Be sure the wheel does not have excessive wobble greater than 0.010 inch. Rotate the motor shaft by hand. It should

freely rotate and not touch the frame at any time. If everything is mechanically correct, the resulting sensor to

pulsewheel air gap will be a nominal 0.019 inch.

4. Position the encoder cover over the mounted encoder frame. Insert and tighten four Phillips head screws. This completes

the mechanical mounting of the unit.

NOTE

The picture below shows how to align the pulse wheel

on the SL85. The pulse wheel is aligned the same way

for both the End-Of-Shaft and Thru-Shaft models. Be

sure the letter "Z" and "This Side Out" are visible

on the face of the pulse wheel after installation.
