2.7 Signal types & scaling
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. a speed or position) in the function block interconnection.

* As of controller software version V3.0 the resolution of an encoder revolution can be parameterised in C00100
(Lenze setting: 16 bits/encoder revolution).
