3.2.2 General
Note
Retain the packing in which the unit was shipped, for use in future transportation.
Caution
Once removed from its packaging, the stage can be easily damaged by
mishandling. The unit should only be handled by its base, not by any
attachments to the moving platform.
Warning
The stage is not suitable for mounting in a vertical (Z-axis) configuration.
Caution
The straightness of motion of the stage could be affected if the mounting
surface is not flat. Care should be taken when bolting the stage to the
worksurface, to ensure that the base plate does not warp. Shims should be
fitted as necessary - see Section 3.2. for more details.
When bolting the stage to the work surface, high tightening torque of the
attachment bolts can result in an increased resistive force on the moving
platform. This in turn can lead to degraded performance and may require the
PID parameters to be adjusted.
As a general guide, 70 N.cm is a recommended nominal torque when tightening
the attatchment bolts.
High drag forces can adversely affect phase initialization, homing, positioning
accuracy and general reliability. Take care to minimize drag caused by
attachments to the moving platform (cables, tubing, electrical wiring),
especially when the stage is changing direction.
When mounting the stage close to other equipment, ensure that the travel of the
moving platform is not obstructed. If equipment mounted on the moving
platform is driven against a solid object, damage to the internal mechanism
could occur. The range of travel is 100 mm (3.94“).
