7.1 Linear motor
Note:
Ensure that no parts are located between the forcer and the magnet track!
The linear motor operates maintenance-free.
7.2 Positioning measurement system
7.2.1 Magnetic positioning measurement system
Note:
Ensure that no dirt particles are located between the encoder and the measuring scale!
The magnetic positioning measurement system works on a non-contact basis and thus requires no maintenance.
Check the magnetic positioning measurement system regularly for soiling, cleaning this when necessary.
Otherwise, accumulating dirt particles will detach under the constant pressure of the cover plate.
7.2.2 Optical positioning measurement system
Note:
Ensure that no dirt particles are located between the encoder and the measuring scale! Only clean using a soft
cloth in order to avoid scratching the measuring scale!
The optical positioning measurement system works on a non-contact basis and thus requires no maintenance.
Regularly check the measuring scale for dirt and clean if necessary, as otherwise the surface of the measuring
scale may become scratched and may no longer function correctly.
7.3 Electromechanical components
The energy chain and the cable have a limited lifetime. However, the lifetime cannot be calculated exactly due to
ambient conditions and drive performance. The following components should therefore be regularly checked for
wear and correct position, and should be replaced if necessary (wearing parts are not covered by the warranty):

Cable in the energy chain (e.g. signs of abrasion on the cable insulation)

Cable plug connections

Distance between the limit switch shelter and sensors (common cause of malfunction of the limit/reference
switch)
Note:
In critical production situations, make sure that there is a stock of wearing parts!
7.4 Linear guideways
7.4.1 Lubrication
As with rolling bearings, the rails of linear motor systems require a sufficient supply of lubricant. This lubrication
reduces wear, protects against dirt and deposits, prevents corrosion and extends service life.
Note:
Observe the instructions of the lubricant manufacturer.
Check the miscibility of different lubricants. Lubricants of the same classification (e.g. CL) and similar viscosity
(maximum difference of one class) are miscible. Greases are miscible when their base oil and thickening types
are the same. The viscosity of the base oil must be similar and the NGLI class may be different by a maximum of
one grade.
Note:
Ensure that old grease, dirt and chippings are removed from the profile rails before lubrication.
