Manual initialization of linear actuators

You can use this function to initialize the positioner without needing to move the actuator to
the lower and upper endstops. The lower and upper endstops of the actuator travel are set
manually. When the control parameters are optimized, the further initialization process runs
automatically.
Requirements
The following requirements must be fulfilled before activating manual initialization:
1. The positioner has been prepared for using on linear actuators.
2. The actuator spindle can be moved completely.
3. The displayed potentiometer position is within the permissible range between "P5.0" and
"P95.0".
Initializing the linear actuator automatically
1. Switch to the "Configuration" mode. To do this, press the
until the display shows the following:
2. Call the "2.YAGL" parameter. To do this, briefly press the
on the display depending on the setting:
3. Check whether the value displayed of the "2.YAGL" parameter matches with the setting of
the transmission ratio selector. If required, change the setting of the transmission ratio
selector to 33° or 90°.
