Measuring system cables
Ready-made cables of Rexroth are in preparation for the electrical connec‐
tion between the output of the linear scale and the input of the scale inter‐
face. To ensure maximum transmission and scale interference safety, you
should preferably use these ready-made cables.
9.15 Linear guiding systems
Linear guiding systems for linear motors are, depending from the motor ar‐
rangement, are necessary due to feed forces and process forces and reacha‐
ble velocity. The used linear guiding system must be able to adjust process
and acceleration force.
Depending on the application, the following linear guides are employed:
●
Ball or roll rail guides
● 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
9.16 Manufacturers of linear guiding systems
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 responibility 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
9.22 "Position and velocity resolution" on page 127 .
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.
