Mounting Considerations
Note: These dimensions include shaft end play and codewheel warp.
For both rotary and linear motion, angular misalignment, EA must be * ± 1 degrees to achieve Encoding Characteristics.
All dimension for mounting the module and codewheel/codestrip should be measured with respect to two mounting posts, as shown above
