Setting the Magnetic Encoder Limits
The mSR100 with the magnetic encoder option comes equipped with adjustable end of travel
limit sensors and a home sensor. The sensors are activated by magnetic targets located in a slot
on the encoder scale bracket as shown in image #4 below. The factory setting location of the
limit sensor targets provide the full nominal 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 pos-
itive direction move the home sensor trips approximately in the center of the travel of the stage.
To adjust travel, simple loosen the screw on the target ~1/4 turn using a 1.3mm hex wrench,
slide the target to the desired position, and tighten the screws.
NOTE: The active 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 active 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.
Caution in setup and programming should be taken to avoid this potential issue.
Limit sensor hysteresis: Limit sensor can have up to 2 mm of hysteresis which means after acti-
vation the stage must move more than 2 mm away from the activation point to release the limit
sensor from being active.
Home sensor hysteresis: Home sensor can have up to 0.6 mm of hysteresis which means after
activation the stage must move more than 0.6 mm away from the activation point to release the
home sensor from being active.
