5.4 Affixing the Load
NOTICE
Mechanical overload due to high torques and high loads!
When affixing the load, high torques and high loads can overload the moving
platform of the P-56x. Mechanical overload can cause damage to the piezo
actuators, sensors and flexure joints of the P-56x and lead to losses in accuracy.
Observe the torque range (p. 43) given for the screws used during installation.
Avoid torques >1.5 Nm on the moving platform.
Do
not
exceed the maximum permissible stress and load capacities according to
the specifications (p. 39).
NOTICE
Warping of the P-56x due to affixing of loads with uneven contact surface!
Affixing loads with an uneven contact surface can warp the P-56x. Warping reduces
the accuracy.
Only affix loads on the P-56x whose contact surface with the moving platform of
the stage has an evenness of at least 20
μm.
For applications with great temperature changes:
Only affix loads on the P-56x that have the same or similar thermal expansion
properties as the P-56x.
NOTICE
Center of load at unsuitable position!
If the center of load is located far outside of the moving platform (e. g. high set-ups
and long levers), the P-56x can be damaged from high strain on the flexure guides,
high torques and oscillations.
If the center of the load to be affixed is far above or to the side of the moving
platform, adjust the controller settings before start-up or contact our customer
service department (p. 37).
