Tools and accessories
Four M6 screws of suitable length (p. 42)
Suitable screwdriver
Mounting the P-5x7/P-5x8
1.
Align the P-5x7/P-5x8 on the underlying surface so that the corresponding mounting
holes in the base body (see figure) and the surface are in line.
2.
Fix the P-5x7/P-5x8 with the screws:
a)
Insert a screw into each hole.
b)
Tighten the screws crosswise. Pay attention to the specified torque range (p. 45)
while doing so.
3.
Check that the P-5x7/P-5x8 is sitting firmly on the surface.

Fixing the Load
NOTICE
Mechanical overload of the platform!
Fixing loads with high torques and heavy loads in general can overload the platform of the
P-5x7/P-5x8. Mechanical overload can damage the piezo actuators, sensors, and flexures of the
P-5x7/P-5x8 and lead to loss of accuracy.
Avoid torques on the platform.
Do
not
exceed the maximum permissible loads according to the specifications (p. 37).
Hold the load and adhere to the specified torque range when tightening (or loosening) the
screws (p. 45).
NOTICE
Warping the P-5x7/P-5x8 when fixing loads with an uneven contact surface!
Fixing loads with an uneven contact surface could warp the P-5x7/P-5x8. Warping reduces the
accuracy.
Fix loads on the P-5x7/P-5x8 only when the surface contacting the P-5x7/P-5x8's motion
platform has a flatness of at least 20
μ
m.
For applications with large temperature fluctuations:
Fix loads to the P-5x7/P-5x8 only when they have the same or similar thermal expansion
properties as the P-5x7/P-5x8.
