8.3 Tabular overview of the parameters
8.3.1 Overview of initialization parameters 1 to 5
Introduction
Parameters 1 to 5 are the same for all versions of the positioner. These parameters are used
to adjust the positioner to the actuator. Normally, setting these parameters is sufficient to be
able to operate the positioner on an actuator.
If you want to get to know all details of the positioner, gradually try out the effects of the
remaining parameters by systematic testing.
Note
Factory-set parameter values are printed in bold in the following table.
