3.6.6.2 Actual value 1 and 2 (actual value 1, actual value 2)
Measured pressure at air ports (2) and (4)
The measured pressure at the air ports (2) and (4) of the valve is given as a signed integer value by
bytes 5 … 4 (PDI) (4) and 3 … 2 (PDI) (2).

3.7 Teach-in run
Various Motion Apps require information about the physical behaviour of the connected peripherals in
order to run. This information is determined by the Motion Terminal during the process referred to as
the "teach-in run". The information is saved as “teach-in data” within a parameter set on the Motion
Terminal controller (
è
3.4.3.8 Teach-in data).
A teach-in run can be executed in 2 different modes:
–
Automatic
An automatic program is executed which determines and saves the corresponding teach-in data.
This mode is sufficient for most applications.
– Manual
The valve is in teach-in mode. The movements of the drive are controlled manually (via the Web-
Config interface or using the higher-order controller).
This allows individual movements to be executed which can each then be analysed by the teach-in
routine.
The type of teach-in run that can be used depends on the Motion App for which the teach-in data are
to be determined. Not all Motion Apps have the option of both types of teach-in run. Some Motion
Apps can be completely operated without a teach-in run having been performed beforehand.
The steps performed automatically during a teach-in run are dependent on the Motion App to be
taught in and, if applicable, documented in the description of the corresponding Motion App.
3.7.1 Prerequisites for starting the teach-in run
Before starting a teach-in run for a particular Motion App, the system and application parameters used
by this Motion App must have been parameterised.
In addition, the application parameter “Motion App to be taught in” (255) must be parameterised
to the ID of the Motion App for which the teach-in run is to be executed (
è
3.4.3.2 Application
parameters).
