Page 4: Before Getting Started
Before Getting Started . . . Check Your Travel Length Verify the travel length of the encoder is correct for your machine. The overall length of the linear encoder is not the travel (See page 13 for travel lengths and corresponding overall dimensions). Do not o set the encoder (extra travel on one end, insu cient travel on the other end). - Page 5 Squareness & Parallelism It is extremely important that the encoder is parallel to the axis of movement, and the reader head is parallel to the encod- er. Avoid skewed installs, as loss of accuracy, premature wear, and/or irreversible damage can occur. Correct Incorrect Disassembly &...

Page 7: Mounting Procedures
Mounting Procedures Wherever possible, the encoder end caps need to be mounted to a machined at surface parallel to the axis of movement. In the case where no machined at surfaces are available on the machine, mounting spars with leveling setscrews should be used. instruments Innovations in Precision... - Page 8 Hold the encoder in place at the desired location Check the alignment using dial indicator to and transfer punch one mounting hole. indicate the front and the top of the encoder body. It must be parallel to the axis Drill and tap with #10-32 standard tap. Required of travel to within a Total Indicator Reading thread depth is 1/2”.
- Page 9 Determine reader head attachment method and prefabricate mounting hardware, if necessary, to match your particular machine. The reader head must be attached to a at surface parallel to the encoder body. Depending on the situation there are two mounting options: Utilize #8 through holes on the side of the Utilize the pretapped M4 holes on the readerhead.
- Page 10 Remove the screw holding the shipping bracket to the encoder end cap. Do not remove the shipping bracket from the reader head yet. Move the machine axis to the dead stop on one end, and mark the reader head location. Gently slide the reader head towards the same end and then slide it back 1/4” (6mm) to allow for a travel reserve (safety factor).
