INSTALLATION

Installation and removal videos for the AV56/67/85/115 are available

on Avtron's web site. Refer to the back page of these instructions for

outline and mounting dimensions. The motor must comply with 1998

NEMA MG 1, section 4, for tolerances on diameters and runout for

shafts and accessory faces. Axial float or endplay must be l

ess than ±0.050".

In preparation for installing the Model AV85 encoder, it is first

necessary to clean both the accessory motor shaft and the mounting

face. These surfaces must be inspected and any paint, burrs, or other

surface imperfections removed.

Installation procedures should be performed only by qualified

personnel. Safety precautions must be taken to ensure machinery

cannot rotate and all sources of power are removed during installation.

ROTOR INSTALLATION

For set screw and endofshaft rotors only: Apply antiseize compound

to the motor shaft. For all rotors: Slide the rotor onto the shaft with

the marking "Motor side" facing in, (toward the motor face). The rotor

centerline must match the sensor centerline. To accomplish this, use

the rotor locating gauge (A28505) and slide the rotor onto the shaft

until it is in the proper position as shown in Figure 1. If a guage is not

available, use the stator housing alignment grooves as

show in Figure 3.

STANDARD CAM SCREW ROTOR INSTALLATION

The motor shaft must extend at least 0.63" from the motor face. Turn

the cam screws of the rotor in the directions shown on the rotor to

engage the cams. Tighten to 5060 inlb [5.6 6.8 Nm] (See Figure 2)

using the 3mm hex wrench. Total cam screw rotation will be less than

one turn.

CAUTION

Do not adjust the cam screws before motor shaft

mounting; bottoming out the screws, or backing them

out excessively, can lead to insufficient shaft holding

force. Thread locker is preapplied on the cam screws.

LARGE BORE SET SCREW ROTOR INSTALLATION

The motor shaft must extend at least 0.63" from the motor face. Apply

thread lock er to the rotor set screw holes, preferably from the inside of

the rotor bore before mounting. Tighten the rotor set screws to 15 inlb

[2 Nm] using the 2mm Thandle hex wrench.

CAUTION

Use only a T-handle or torque hex wrench to tighten

set screws; using a right angle wrench will not provide

enough holding force, and the rotor may slip.
