Technical Features
3.5.1
Linear Encoder (Sensor)
The positioner is equipped with an optical linear encoder. Refer to the table in the
"Specifications" section (p. 33) for the encoder resolution.
Optical linear encoders measure the actual position directly (direct metrology). Therefore,
errors occurring in the drivetrain such as nonlinearity, backlash or elastic deformation, cannot
influence the measurement of the position.
3.5.2
Reference Switch
The positioner is equipped with a direction-sensing reference switch, which is located at about
the midpoint of the travel range. This sensor sends a TTL signal indicating whether the
positioner is on the positive or negative side of the reference switch.
See the controller user manual and/or associated software manuals for the commands that
make use of the reference point signal.
