Signal type entry
In general, it is possible to assign a certain signal type to the inputs and outputs of the
Lenze function blocks. There are e.g. digital, scaled, position, acceleration and speed
signals.
A corresponding ending (preceded by an underscore) is added to the identifier of the
corresponding input/output to indicate the signal type.
15.1.3
Scaling of physical units
With regard to the parameter setting & configuration of the controller it is very helpful to
know the signal types and their scaling listed in the following table, which are used to
process physical values (e.g. an angular velocity or position) in the function block
interconnection.
