12.1 Mounting surface preparation
To ensure correct operation, the mounting surface should be prepared as follows:
•
surface flatness requirement of 0.05 mm/m
•
surface should be free of paint and burrs
•
refer to installation drawing for required mounting hole positions (see
To further simplify and help reduce installation time, it is recommended that the machine axis to
which the encoder is to be mounted is prepared with a datum edge or aligned dowel pins to help
locate the edge of the extrusion and ensure parallelism to the axis of motion.
