1.5.7 Signal types and scaling
A signal type can be assigned to most inputs and outputs of the Lenze function
blocks/system blocks. The following signal types are distinguished:
ƒ digital and analog signals
ƒ position and speed signals
The identifier of the corresponding input/output variable has an ending (starting with an
underscore). It indicates the signal type.
