| Mounting
Autotech resolvers are designed to
operate reliable under extremely hostile environments, such as:
continuous mechanical shock, vibration, extreme temperature and humidity
changes, oil mist, coolant and solvents. Still ordinary
precautions to prevent damage to bearings of any rotation device should
be followed to prolong their life.
- It is recommended that the Autotech
encoder mounting bracket (MMB-EM359-010) be used, wherever possible,
for size 40 resolvers.
The servo-mount resolvers may be mounted either with traditional
servo-clamps or through the four threaded mounting holes on the face
of the resolver.
- If the resolver is to be axially shaft
driven, be sure that the shafts are aligned. Misaligned shafts
can destroy resolver bearings.
- If a pulley, coupling or sprocket is
mounted to the resolver shaft, DO NOT hammer or press on the
shaft. DO NOT force fit anything on to or off of the resolver
shaft.
Zero Reference-Size 40
resolvers
(SAC-RL100, E8R and SAC-RL210)
Size 40 resolvers are
at approximately zero when the shaft key way is aligned with mounting
hole and conduit fitting.

-
If the resolver is
belt-driven or chain-driven, DO NOT OVERTIGHTEN the drive belt
or chain. Too much side loading (radial) can destroy the
resolver bearings. Side loading is not allowed for E6R and
RL101 (size 11) resolvers.
-
To maintain the NEMA 13
rating of the resolver, the following precautions must be
taken: a) sealing compound must be used when fitting the
conduit pipe; b) the bearing seal must be checked once every six
months and replaced if necessary. Lubricating the bearing seal
periodically prolongs its life.

Zero Reference:
For most resolver types, the approximately zero reference may be
located by aligning the shafts as shown in the figures below.
CAUTION:
RL101 (size 11) resolvers must be coupled to an external shaft using
a flexible coupling.
Zero Reference-Size 25
resolvers
(E7R)
Servo mount resolvers:
Align shaft keyway with the face plate retaining screw which is in line
with a mounting hole.
Flange mount resolver:
Align shaft keyway with the face plate retaining screw that lies midway
between two mounting holes.
