2.2 Encoder Frame Installation

To install the encoder frame, perform the following steps.

1. Orient the encoder frame so the 4.5 inch I.D. surface will fit over the 4.5 inch C flange (encapsulated side toward the

motor). Mount frame onto the motor flange. Insert the four 3/8 inch x 16 UNC socket head cap screws through the frame

and into the motor frame. Use a 5/16 inch hex wrench to tighten a nominal 25 foot pounds. See Figure 3.

Rotate the pulse wheel so the set screw or label "This Side Out" are visible, away from the motor. Slide the pulse

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

machined recess in the encoder frame. See Figure 4. We recommend you 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 pulse wheel under

the sensor.

With the pulse wheel properly aligned, use a 9/64 inch hex wrench to tighten the 8 x 32 UNC socket head cap screw in

the pulse wheel clamp to a nominal 30 in-pounds.

Pulse wheels which utilize the set screws should be tightened to a nominal 30 in⋅lbs torque. 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 pulse wheel air gap will be a nominal 0.019

inch.
