4.3.2. Mechanical Hard Stop Adjustments
Stages equipped with the hard stop option (-HS) have the hard stops set at the factory prior to
shipment. Although the hard stops are adjustable, contact Aerotech before you change their
position because the optical limits could need to be updated. If you change the hard stop position
but do not update the optical limits, the stage travel could hit a hard stop and cause damage the
stage or payload.
WARNING : Mechanical Hazard! Do not adjust the hard stops to an angle smaller than
the limit travel of the stage. Maintain at least ±5° of travel between the optical limits
and the hard stops. Allow for enough over-travel between the electrical limit and the
hard stop for the stage to completely decelerate and stop before it hits the hard stop. If
the stage hits the hard stop, that could result in damage to the stage and payload and
the possibility of injury.
1. Disconnect all electrical power from the stage.
2. Remove the Graduated Scale. It is secured with four [QTY. 4] M2.5 socket head cap screws (
Figure
4-2 ).
Note the orientation of the scale so that it can be returned to the same position.
DANGER : Pinch Point Hazard! You must be careful when you handle the stage with
the graduated scale ring removed and the bumper and hard stops exposed.
