Setting the Magnetic Encoder Limits
The mSR080 with the magne c encoder op on comes equipped with adjustable end of travel limit
sensors and a home sensor. The sensors are ac vated by magne c targets on the side of the stage as
shown in image #2 below. The factory se ng loca on of the limit sensor targets provide the full nomi-
nal travel of the stage with approximately 2mm of over travel before the stage encounters the hard
stop. The home sensor is set such that during a posi ve direc on move the home sensor trips approx-
imately in the center of the travel of the stage.
To adjust travel, simple loosen both screws on the targets ~1/4 turn using a Philips screw driver, slide
the target to the desired posi on, push the target upward toward the carriage top to seat the target
on the bo om side of the carriage (see image #2) and ghten the screws.
NOTE: The ac ve length of the target is approximately 9mm, if the target is moved greater than 9 mm
from the stage hard stop, the stage can move beyond the ac ve area of the target and shut off on the
other side of the target. This can lead to having the stage behind a limit sensor. Cau on in setup and
programming should be taken to avoid this poten al issue.
Limit sensor hysteresis: Limit sensor can have up to 2 mm of hysteresis which means a er ac va on
the stage must move more than 2 mm away from the ac va on point to release the limit sensor from
being ac ve.
Home sensor hysteresis: Home sensor can have up to 0.6 mm of hysteresis which means a er ac va-
on the stage must move more than 0.6 mm away from the ac va on point to release the home sen-
sor from being ac ve.
