Hard Stop: Speed Limitation Versus Load
IDL225-LM stages use electrical end-of-run and elastomer hard stops to
stop the carriage as smoothly as possible past the end-of-runs. The
overtravel allowed by the hard stops is 0.35 in. (9 mm).
When the stage is used with a controller supplied by Newport, the factory
settings of the "software limits" prohibit any commanded motion beyond
this travel range.
Nevertheless, for safety reasons, follow the recommendations
above to minimize risk of mechanical damage, in case of failure
or incorrect adjustment of parameters.
The maximum speed of the stage must be limited so that the
hard stops will always stop the carriage in 0.35 in. (9 mm) or
less, to avoid any shock between the carriage and stage body.
The graph at left, provides stage speed as a function of applied
load. This curve defines allowed operating conditions to stop
within the 0.35 in. (9 mm) over-travel allowed by the hard stops.
To stop within this distance, the user must maintain speed and
load within this tolerance. This graph assumes correct wiring of
the electrical end of runs will cut motor power before contact
with the hard stop.
