2.3
Signal types & scaling
It is very helpful for the parameterisation & configuration of the controller to know the signal types
and their scaling listed below, which serve to process physical quantities (e.g. a speed or position)
within the function block interconnection.
Scaling of physical units
Note!
From software version V3.0
the resolution of an encoder revolution can be
parameterised in
(Lenze setting: 16 bits/encoder revolution).
