Important for positioning accuracy:
–
The cylinder, guide, measuring system and load must be rigid in the direction of movement, have
very little play and must be connected flush with each other.
–
The play between the drive, guide, load and displacement encoder must be smaller by at least the
factor 10 than the required tolerance. The play should be
0.1 mm.
Note
Lateral loadings produce false measuring results and may damage the displacement
encoder.
Use an external guide for the payload in order to prevent transverse loadings on the
drive.
Use fastening elements which will permanently resist the forces of acceleration.
If necessary, provide a sufficiently large energy chain in order to minimise the effects of bending
forces on the positioning behaviour.
Note
Observe the notes in the operating instructions for the axis used.
Ensure that the following is complied with:
–
the permissible transverse force
–
the permissible longitudinal force
–
the permitted mass moment of inertia
–
the maximum permissible speed and swivel frequency
Notes on coupling (piston rod drive)
If a coupling is required between the piston rod and the guide:
Check the play of the coupling.
The requirement is: coupling play ≤ 0.05 mm
Set the play of the coupling correspondingly.
Too much coupling play leads to:
–
noise due to knocking on the coupling
–
increased wear on the coupling
–
worse operating behaviour
Make sure that the coupling play does not exceed 0.05 mm.
