The 401/402/403XE positioner can be mounted in a normal, side, vertical, or inverted orientation. For vertical
(Z axis) mounting, care must be taken since certain ballscrew and load combinations can backdrive in a pow-
er loss situation. For all orientations, the cables should be secured as to not interfere with the movement of
the carriage.

Mounting Surface Requirements
Proper mounting of the 401/402/403XE positioner is essential to optimize product performance. All specifica-
tions are based on the following conditions:
•
The positioner must be bolted down along its entire length.
•
The positioner must be mounted to a flat, stable surface with flatness error less than or equal to
0.013mm/300mm
(0.0005”/
ft).
•
Catalog specifications may deviate for a positioner mounted to a surface that does not meet the above
conditions.
•
If the surface does not meet the above conditions the surface may be shimmed to comply with these re-
quirements.
•
If mounting conditions require that the table base be overhung, catalog specifications will not be met over
that portion of the table. Additionally, in X
-
Y systems the overhung portion of the Y axis may not meet
specifications due to the additional error caused by deflection of the unsupported base. Contact factory
for guidelines on specifications of overhung applications.
Base Through Hole Mounting

401/402/403XE
The 401XE, 402XE and 403XE have counterbored clearance holes in the
base of the unit for mounting. To properly mount the positioner along its en-
tire length, it is required that all counterbored holes be used. See Chapter 2
for hole location and size.
If equipped with a hard cover (R1 option), the cover needs to be removed to
access the holes. To do so, use a 2.0mm hex wrench to remove the two but-
ton head screws at each end of the cover.
