An oscilloscope can also be used to verify proper output of the

AV56 encoder at the encoder connector itself and at the drive/

controller cabinet. If the outputs show large variations in the

signals at steady speed (jitter or "accordion effect", see figure

5), check rotor position. If the rotor position is correct, the motor

or shaft may be highly magnetized. Replace any magnetized

material nearby with non-magnetic material (aluminum, stain-

less) (shafts, etc). If variations persist, consider replacing with

super-shielded models, option -005.

Do not use rotors from THIN-LINE I (M56, M56S,

M67, M85, M115) with AV115. This will cause incor-

rect PPR output, but the AV115 LED will remain

green.

ENCODER REMOVAL

The AV115 stator housing can be removed by loosening and

removing the socket head cap screws.

CAM SCREW ROTOR REMOVAL

Disengage the (2) cam screws by turning them counterclock-

wise less than 1 full turn. The cam heads will visibly move

away from the shaft. Remove the rotor by hand by pulling it

away from the motor. If the rotor will not move, do NOT use a

gear puller, and do not use a heat gun. Instead, insert two M6

screws, >25mm length into the Jack Screw Holes shown in Fig

2. Alternately tighten the screws to push the rotor away from

the motor and remove it.

LARGE BORE SET SCREW ROTOR REMOVAL

Disengage the (2) set screws by turning them counterclockwise

until removed from the rotor. Retain the set screws. Remove

the rotor by hand by pulling it away from the motor. If the rotor

will not move, do NOT use a gear puller, and do not use a heat

gun. Instead, pry the rotor away from the motor gently, being

careful to only pry against the rotor metal hub and not the mag-

netic outer strip.
