● Slide ways
● Hydrostatic guides
● Aerostatic guides
The following requirements should be taken into account when a suitable lin‐
ear guide system is selected:
●
High accuracy and no backlash
● Low friction and no stick-slip effect
● High rigidity
● Steady run, even at high velocities
● Easy mounting and adjustment
Manufacturer
Linear guiding systems are not in the scope of delivery of the mo‐
tor and must be ordered separately. The selection of a suitable
linear guiding system is in the sole responsibility of the machine
manufacturer. When selecting linear measuring systems please
observe that this system uses sinusoidal instead of rectangular
output signals. With sinusoidal output signals, a significantly high‐
er position resolution and better position accuracy is reached via
special evalutation revolution of our controllers. See also chapter
9.21 "Position and velocity resolution" on page 128 .
In the following you will find an incomplete list of manufacturers of suitable
length measuring systems for linear motors: Furthermore, other manufactur‐
ers are available which cannot be listed all.

9.16 Braking systems and holding devices
The following systems can be used as braking systems and/or holding devi‐
ces for linear motors:
●
External braking devices
● Clamping elements for linear guides
● Holding brakes integrated in the weight compensation
Further designs about stand-still of linear motors are given in
chapter 9.17 "End position shock absorber " on page 123 and
chapter 9.20 "Deactivation upon EMERGENCY STOP and in the
event of a malfunction " on page 125 as well as in the appropri‐
ate functional description of the drive controller.
