1.2.7 Signal types and scalings

Most inputs and outputs of Lenze function blocks/system blocks can be assigned to a certain signal

type. We distinguish between digital, analog, position and speed signals.

The identifier of the corresponding input/output variable has an ending (starting with an underscore).

It indicates the signal type.

Note!

Due to their scaling, analog signals have an asymmetrical resolution range (−200 % ... +199.99 %):
