Chapter 4 - Base Mounting Procedures
Mounting Surface Requirements
Proper mounting
of the 401/402XR is
essential
to optimize product performance. All specifications
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 a flatness error less than or equal to
0.013mm/300mm.
•
Catalog specifications may deviate for positioners mounted to surfaces that do not meet the
above conditions.
•
If the surface does not met these specifications the surface can be shimmed to comply with
these requirements.
•
If mounting conditions require that the table base is
overhung
, table 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 met
specifications due to the additional error caused by deflection and non-support of the base. Contact
Parker Hannifin Corporation for guidelines on specifications of overhang applications.
Base Mounting Methods
Base thru holes
The 401/402XR tables have counter bored holes in the base of the unit. See Dimensional
Drawings, Chapter 2, for hole locations. See Internal Access Procedure, Chapter 6, to gain access
to mounting holes.
Riser Blocks
Tools Required:
Allen Key
Most of the motors used with the 401/402XR series have a taller profile than the positioner. Thus
the unit cannot be mounted with the motor and table in the same plane. Riser blocks can be
provided to space the table above a mounting surface.
•
Locate sufficient amount of Riser Blocks for the required length of travel.
•
Lay out Riser Blocks such that the entire length of the positioner is supported.
•
Access interior of the positioner. See Internal Access Procedure Chapter 6.
•
Mount Riser Blocks to the positioner using screws provided.
•
Mount positioner to the work surface using counter-bored holes in the riser blocks.
