Technical Features

3.8.1

Rotary Encoder

The L-406.x0DG10 and L-406.x0DD10 models are equipped with an incremental rotary encoder.
A rotary encoder is implemented at a rotating point in the drivetrain, e.g., the motor shaft.
3.8.2

Limit Switches

The L-406 is equipped with optical limit switches.
Each limit switch sends its signal to the controller on a dedicated line. The controller then stops
the motion. If the controller does not stop the motion in time, the positioner runs into the hard
stop.
See "Limit Switch Specifications" (p. 46) for more information.
3.8.3

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.
