The required PC software is included in the scope of delivery of the controllers from PI. The
operation of the controllers is described in the corresponding user manuals.
The operating parameters must be adjusted depending on the version of the L-402 used.
If extension cables and/or adapter cables are required to connect the L-402 to the controller,
they must be ordered separately.
To order, contact our customer service department (p. 25).
3.7 Technical Features
3.7.1 Rotary Encoder
The models with DC motors are equipped with a rotary encoder. A rotary encoder is
implemented at a rotating point in the drivetrain, e.g., the motor shaft. To determine the
relative position, the controller counts the encoder signals, the so-called impulses.
3.7.2 Limit Switches
The L-402 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 linear actuator runs into the
hard stop.
See "Limit Switch Specifications" for more information (p. 29).
3.7.3 Reference Switch
The L-402 is equipped with one direction-sensing reference switch that is located at about the
midpoint of the travel range. This sensor transmits a TTL signal that indicates whether the linear
actuator is on the positive or negative side of the reference switch.
See the controller's user manual for the commands that make use of the reference signal.
For more information, see "Reference Switch Specifications" (p. 29).
