done in form of a reference run, by which the zero-position of the actuator is
determined.
After powering on the electronic unit a warning message is sent over the WARN output
to indicate that the motors have not yet been initialized. The initialization procedure
always starts from motor A. As soon as this is done the initialization of motor B begins,
and so on. After motor D has initialized the warning message is removed.

The linear motors of the LinMot
electronic unit. After the initialization the actual position of the slider is stored in the
electronic unit until the signal power supply to the unit is interrupted. The actual
position is still maintained when the linear motor is not powered and the slider is moved
from its position.
Three types of initialization are available for the linear motors of the LinMot
When initializing, the slider is moved with a user-definable speed until it encounters a
stop. As soon as the slider stops its position is taken as the zero-position.
Figure 4-10: Initialization to a stop (move out)
In this mode it can be specified whether the slider should be moved outwards or inwards
(the figure shows the "move out" option).
Hint: by using a stop that is fixed to the machine and not to the stator of the linear
motor, re-adjusting the stator position will not be necessary when replacing the motor,
because the reference stop for the zero position remains the same.
In order to initialize the motor by means of a trigger signal a digital position sensor is
needed to detect the slider when it is in the desired zero-position. The slider moves with
a user-definable speed over the position sensor. As soon as the sensor detects the slider
the actual position is taken as the zero-position.
