1.2
Proper use
The linear units serve to move securely attached loads along the guide slides/slide plates or
supporting profiles in a linear direction in an environment where there is no danger of explosions and
in accordance with the operational and environmental conditions specified for this product. The product
can be installed as required (in a horizontal, vertical or diagonal) position.
In general, the ballscrew drives in the linear units are not self-locking.
If installed vertically, the linear unit motor (in this case the spindle of the ballscrew spindle and the
weight of the loaded slide plate must be calculated) should therefore have a holding brake to secure
the movable guide slide of the linear axle from falling/sinking when the power is off. If no holding brake
(e.g. magnetic brake) is fitted to the motor, another (electric) mechanical brake must be used, e.g. on
the end support of the ball spindle.
The linear units are incomplete machines (compare Article 2g of MD 2006/42/EC). Here an incomplete
machine is defined as follows (quote):
'An incomplete machine is a unit which almost forms a machine but which cannot fulfil any specific
function on its own.
A drive system is an incomplete machine.
An incomplete machine is only intended to be installed into other machines or other incomplete
machines or equipment, or joined together with these to form a machine as defined in this directive.'
The linear units LES4
– LES5 – LES6 are intended for installation into a machine or into other
incomplete machines.
The product should not be used outdoors or to transport people or in the food industry and clean
rooms.
Any other use than those described above is not considered correct and can lead to personal injuries
and damage to property.
