CHECKING THE
ENCODER

Encoder Mounting and General Information
The provided encoder is a precision instrument which outputs
3000 bi-directional quadrature pulses per revolution of the
shaft.
Do not apply excessive axial or radial thrust on encoder shaft
(rated for 30lbs. axial thrust).
Do not press or dive gears or pinions on the encoder shaft.
Encoders are an instrument containing an accurately posi-
tioned electronic system. Dropping will cause damage as the
inner disc is made of glass and is easily damaged.
Parts should slide freely on the shaft prior to securing with a
clamp or set screw. (.001 slide fit).
Excessive clearance in mounting hole can lead to inaccuracy.
If encoder is taken apart, the warranty is invalidated. (seal bro-
ken)
Encoder wheel should not exceed .001 TIR.
If mounting encoder and wheel assembly on belt or roller:
● Tighten bracket to facilitate no vertical movement.
● Apply encoder wheel to surface to be measured in position
that will not allow slippage, but confirms to above warn-
ings.
Alternatives to above mounting of encoder:
● Direct drive through solid (precision board) coupling to
encoder on output side of any type gear box to remove error
due to backlash in gears.
● Use O-ring as a drive belt from belt sheave to encoder
wheel. (Items must be machined on mandrels or actual
mounting shafts to facilitate precision TIR to obtain best
accuracy.)
