Installation Guide Linear Modules
4.2 Mounting the Load
The load is mounted on the front plate of the SM01 linear modules. For this purpose, threaded holes and fits
for dowel pins are machined into the plate.
The complete dimensions of the front plate as well as the positions and specifications of the threaded holes
and fits can be found in chapter 12.
The center of gravity of the mounted load mass should be centered and the load should be placed as close
as possible to the mounting plate. This ensures an even distribution of the mass and minimizes the
maximum load on the linear module.
•
It must be ensured that the front plate is not bent by the mounting of the load. This is
especially the case if the mounting side of the load is not flat. In this case, it is
recommended to place washers between the front plate and the load and to use only
two fixing screws. Bending the front plate will result in the guide becoming sluggish.
•
The back plate is only used to increase rigidity and must not be used for load mounting.
•
The holes provided must be used for mounting and load mounting. Mechanical
modification of the stator is prohibited and all mechanical modification of the front plate
is not recommended.
4.3 Vertical Load Balancing MagSpring®
When installed vertically, linear modules and other direct drives must apply a constant force to counteract
the weight force. With a magnetic spring, MagSpring®, installed parallel to the linear motor, the weight force
can be passively compensated. Then the drive is only used for the actual positioning operation or the
application of the dynamic forces required and therefore can be sized accordingly smaller.
•
In an unloaded case or when the SM01 module is in the horizontal position, it must be
ensured that the MagSpring does not pull the moving part of the guide into the end
stops in an uncontrolled manner, which can lead to damage. The maximum speed at
which the guide may be driven onto the end stops without the use of attenuators is 0.1
m/s and must be limited to initialization runs and emergency stop situations.
•
Do not mount, hold or lift the SM01 on the MagSpring. Increased forces on the
MagSpring stator may deform the mounting component and affect alignment.
