11.1 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.
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.
