The encoder must be driven by a positive drive rather than a

friction drive. The following means of coupling are acceptable

when properly installed: Direct Coupling, Timing Belt/Pulleys,

Chain/Sprockets.

With a direct drive, use a flexible coupling and align the shafts as

accurately as possible. Example: For a size 62 Thomas Miniature

Coupling, angular misalignment must be less than 1.34°, parallel

misalignment less than 0.028", and axial float less than ± 0.031".

Overhung loads should also be minimized. Installations using

timing belts/pulleys should have just enough belt tension to

eliminate belt sag. Excessive tension will shorten belt and bearing

service life. Refer to the specifications for maximum bearing load

ratings. If a rubber slinger disc is used, position it on the shaft so

it will rotate freely.

CAUTION

Do not force or drive the coupling onto the shaft or

damage to the bearings may result. The coupling

should slide easily on the shaft. Remove nicks and

burrs if necessary. Consider driving shaft endplay

when positioning coupling.

For more details on alignment specifications, measure ment

techniques, and special considerations in specifying and installing

drive components, refer to separate installation instructions in

the Avtron PULSE GENERATOR HANDBOOK.

NEMA 56C FACE MOUNTING INSTRUCTIONS

1) Apply anti-seize compound to inner circumference of coupling

(both motor and encoder side).

2) Loosen set screws in coupling and apply thread locker to set

screws.

3) Place coupling on motor shaft, inserting to depth per

manufacturer's instructions.

4) Attach coupling to motor shaft using set screws per

manufacturer's instructions.

5) Bolt mounting flange (flowerpot) to motor C-Face, using

thread locker with fasteners.

6) Slide encoder shaft into other side of coupling. DO NOT

FORCE. Ensure 1/4" keyway aligns with coupling set screw

location.

7) Ensure C-Face on mounting flange matches and aligns with

encoder C-Face precisely.

The optional foot mounting bracket kit is Avtron P/N A28380.

Read all of the following instructions and the Avtron PULSE GEN-

ERATOR HANDBOOK prior to beginning any work.

The M6 performance and life will be directly affected by the

installation. Following this sequence of steps is recommended.

1) The foot mounting bracket must be secured to a flat, rigid,

vibration free steel or aluminum base which can be machined

to accept 5/16-18 mounting hardware. See next section.

2) Temporarily mount the M6 to the foot bracket, install the

coupling to the M6 and driver and verify that the location is

suitable for installation.

3) If the M6 encoder, bracket, and coupling are suited to the area,

check motor/encoder shaft alignment with a straight edge from

multiple positions around the shaft circumference to verify that

it meets specifications.

4) While maintaining alignment, precisely mark the position of the

foot bracket on its mounting base.

5) Remove the M6. Transfer punch or layout the mounting hole

pattern as indicated on outline drawing.

6) Machine four, 3/8" diameter through holes or tap four, 5/16-18"

holes in center of base slots to give some degree of freedom

in final alignment.

7) Reinstall the M6 with the flexible coupling loosely in place, and
