5 Installation
12 Version: 1.2.0 MP164E L-402 Mniature Stage
INFORMATION
The use of locating pins during mounting reduces deviations from the ideal alignment of the
stage.

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 L-402 and the
application, in accordance with the legal regulations.
5.2 Attaching the L-402 to a Surface
NOTICE
Warping of the L-402 due to mounting on uneven surfaces!
Mounting the L-402 on an uneven surface can warp the L-402. Warping reduces the accuracy.

Mount the L-402 onto an even surface. The recommended flatness of the surface is ≤10
µm.

For applications with large temperature changes:
Only mount the L-402 on surfaces that have the same or similar thermal expansion
properties as the L-402.
Requirements

You have read and understood the general notes on installation (p. 11).

You have provided a suitable surface (for the required position and depth of the holes
for accommodating the screws and locating pins, see "Dimensions" (p. 30)):
− For mounting on the bottom of the L-402: Two M2 threaded holes are provided.
− For mounting on the front of the L-402: Two M2.5 threaded holes are provided.
− If you use locating pins to align the L-402: Two 1.5 mm Ø locating holes are present.
− The flatness of the surface is ≤10 µm.
− For applications with large temperature changes: The surface should have the same
or similar thermal expansion properties as the L-402 (e.g., surface made of
aluminum).

You have accounted for the space required to route cables without bending and
according to regulations.
