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
WIRING DIAGRAMS
tighten down all mounting hardware. Check motor/encoder
shaft alignment with a straight edge from multiple positions
around the shaft circumference to verify that it meets
specifications. Use thread locker supplied on cap screws which
mount M6 to foot bracket.
8) Ensure any flat or keyway on the motor and encoder shaft are
aligned with the set screw holes of the flexible coupling. Apply
thread locker to coupling set screws and tighten per
manufacturer’s recommendations.
9) Recheck alignment and tighten all hardware after first several
hours of operation.
MINIMIZE DOWNTIME: Should M6 replacement be required,
leave the foot mounting bracket installed on its base and mount
the new M6 to the bracket. This maintains the original alignment.
WIRING INSTRUCTIONS
The M6 can be wired for single phase, two-phase, with or without
complements, with or without markers. See wiring diagrams on the
following page.
CAUTION
Do not wire the M6 Encoder while energized. Doing so
may damage the encoder, and/or cause risk of fire or
explosion.
For bidirectional operation of the encoder, proper phasing of the
two output channels is important. Phase A channel leads phase B
channel for clockwise shaft rotation as viewed from the anti-drive
or accessory end of the motor (M6 mounting end).
CORRECTIVE ACTION FOR PHASE REVERSAL
1)
Remove Power.
2) Exchange wires on cable, either at encoder cable end, or at
speed controller end (but not both).
a)
Single Ended 2 Phase Wiring (see wiring diagram)
Exchange A and B at the use end of the wires.
b)
Differential 2 Phase Wiring (see wiring diagram)
Exchange
either A with A– in the phase A pair OR B with B–
in the phase B pair but
NOT both.
3) Apply Power.
4) Verify encoder feedback is correct, using hand rotation of
shaft, or jog mode of the speed controller.
Refer to the system drawing for specific cable requirements where
applicable.
Physical properties of cable such as abrasion, tensile strength,
solvents, marine applications, etc., are dictated by the specific
appli cation. Requirements for hazardous locations are dictated
by the rele vant codes. General electrical requirements are:
stranded copper, 20 AWG (.52mm
2
) through 14 AWG (2.08mm
2
),
each wire pair individually shielded with braid or foil with drain
wire, 0.05 uF maximum total mutual or direct capacitance, outer
sheath insulator, 2,000 ft. max. (See line driver specifications).
Temperature ratings of wire and wire glands should be 20°C over
the maximum expected ambient or motor temperature to allow for
temperature rise in the encoder itself.
MAINTENANCE
CAUTION
Do not open the M6 housing. Doing so will void the
warranty and may cause the risk of fire or explosion.
