L-731 / V-731 Precision XY Positioner
NOTICE
Damage due to removed caps or screws!
Removing caps and screws can lead to contamination and failure of the L-731 / V-731.
Do
not
loosen screws on the positioner, except when removing the transport lock (p. 20).
Do
not
remove any caps other than the ESD protection.
Remove the ESD protection only when connecting to the controller.
INFORMATION
For optimal repeatability, all components must be connected firmly together.
If possible, simulate the positioner motions with a mounted load or make suitable
calculations to detect collisions or unfavorable center of gravity constellations.
If necessary, take suitable constructive measures to avoid collisions and instability in
the overall system.
Avoid or mark danger zones that result from the installation of the positioner and the
application, in accordance with the legal regulations.

Attaching the L-731 / V-731 to a Surface
NOTICE
Warping of the L-731 / V-731 due to mounting on uneven surfaces!
Mounting the L-731 / V-731 on an uneven surface can warp the L-731 / V-731. Warping
reduces the accuracy.
Mount the L-731 / V-731 onto an even surface. The recommended flatness of the surface is
≤5 µm.
For applications with large temperature changes:
Only mount the L-731 / V-731 on surfaces that have the same or similar thermal expansion
properties as the L-731 / V-731.
NOTICE
Damage to the V-731 by impact of the platform with hard stops!
The V-731 has a linear drive without self-locking. When the XY positioner is tipped, the
platform can hit the hard stops without braking.
Only mount the V-731 onto absolutely horizontal surfaces.
Remove the transport lock just before mounting onto the surface.
