Encoding Characteristics
Encoding Characteristics over the Recommended
Operating Conditions and Mounting Conditions. These
characteristics do not include codewheel/codestrip
contribution.
1. The typical values are average over the full rotation
of the codewheel at Nominal Mouting Position and
Typical Operating Conditions.
2. For a codestrip, the Typical Values are obtained at
zero angular displacement and Typical Operating
Conditions.
3. Maximums are the worst case values predicted over
the full range of Recommended Mounting Tolerances
and Operating Conditions, with consideration to popu-
lation shift.
