Use of function blocks

You can configure the signal flow in the controller yourself by interconnecting function blocks. This
makes it easy to adapt the controller to different applications.

2.3.1

Signal types

Every function block has a specific number of inputs and outputs which can be connected to one
another. The signal types occurring at the inputs and outputs depend on the individual functions:

l

Quasi analog signals

– Symbol:

H

– Unit: %

– Identification: a

– Value range: ±16384 = ±100 %

– Resolution: 16−bit, scaling ±16384

¢ ±100 %

l

Digital signals

– Symbol:

G

– Unit: binary, with HIGH or LOWlevel

– Identification: d

– Resolution: 1−bit

l

Speed signals

– Symbol:

F

– Unit: rpm (for display, internal representation in [inc/ms])

– Identification: phd

– Value range: ±2

15

− 1

– Resolution: 16−bit

l

Phase signals

– Symbol:

E

– Unit: inc

– Identification: ph

– Value range: ±2

31

− 1

– Resolution: 32−bit, scaling 1 revolution

Only signals of the same type can be combined. I.e. an analog output signal of a function block can
only be linked with the analog input of another function block. If you try to combine two different signal
types, the combination will not be accepted.
