Incremental encoder accuracy depends on the mechanical and electrical two factors,
these factors are: Raster indexing error, disc eccentricity, bearing eccentricity, e-reading
Several means into the optical portion of the errors and inaccuracies. Determine the
encoder resolution is measured in electrical degrees, the encoder accuracy depends Set
the pulse encoder generates indexing. The following electrical degrees with a 360 ° rotation
of the shaft to said machine, and rotation of the shaft must be a full week of Period. To know
how much electrical equivalent of the mechanical angle of 360 degrees can be
calculated with the following formula: Electrical 360 = Machine 360 ° / n ° pulses / revolution
Encoder indexing error is the electrical angle of the unit two successive pulse maximum
offset to represent. Error exists in any encoder, which Is caused by the aforementioned
factors. Eltra encoder maximum error is ± 25 electrical degrees (declared in any condition),
equivalent to the rated Offset values ± 7%, as the phase difference 90 ° (electrical) of the
two channels of the maximum deviation ± 35 electrical degrees is equal to ± 10% deviation
