Figure 4-11: Initialization with a position sensor
The trigger signal of the sensor is forwarded to the electronic unit by the higher-level
control system. Here, too, it can be specified whether the system should consider the
active edge of the trigger signal when the slider is moved inwards or outwards.
If the trigger signal is already High when the initialization is started, the slider is first
moved in the opposite direction until the signal goes low. At this point the slider is
moved in the specified direction to trigger the active edge.
In this third case no reference run is executed. The actual position of the slider upon
powerup of the electronic unit is saved as zero-position. This implies that the slider must
already find itself in the desired zero-position before powering up the unit.
After the initialization is done in one of the three modes it is possible to check if the
slider can move freely along its entire stroke range. During this process the slider is
moved over the specified range with same specified speed. Should the slider encounter
an obstacle within its stroke range an error message is sent out to inform that the
initialization was not completed successfully.
