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.
16.1.3 Scaling of physical units
With regard to the parameter setting & configuration of the inverter 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.
