Alignment for running accuracy Due to the manufacturing process of the extruded profiles, a linear axis has a certain tolerance in terms in straightness and twist. The deviations are generally well within the specifications of EN 12020-2 in the case of the product.

Perform the following lateral alignment procedure for running accuracy.

￿The mounting surface must be machined smooth and flat.

￿First, slightly tighten the screws of the slot nuts or the clamping claws.

￿Provide a reference plane alongside the linear axis.

￿Place a dial gauge onto the carriage.

￿Move the carriage and record the deviation with reference to the ref- erence plane over the entire stroke.

￿Correct the deviations by lateral alignment of the linear axis and by tightening the screws appropriately. Observe the standard tighten- ing torques 47.

4.2.3Mounting the contact plate

A contact plate must be mounted to the carriage for the inductive sen- sors. Fastening threads are located at both sides of the carriage.

Unless otherwise specified, the standard tightening torques indicated on page 47 apply.

Before mounting See chapter 7 "Accessories and spare parts", subchapter 7.5 "Sensors and additional parts" for suitable contact plates.

You need a set of Allen keys.

￿Clean all parts you will use.

￿Check all parts for damage; repair damages.

Procedure

￿For mounting, select the side of the carriage that will be easily accessible for service.

￿Screw the contact plate to the carriage with M4 screws.

￿Align the contact plate in parallel with the carriage so as to have the same switching distance on both sides.
