3.1 Working with function blocks

The signal flow of the controller can be configured by connecting function blocks. The controller can

thus be easily adapted to diverse applications.

3.1.1 Signal types

Each function block has a certain number of inputs and outputs, which can be interlinked.

Corresponding to their respective functions, only particular signal types occur at the inputs and

outputs:

l Quasi analog signals

– Symbol: 

– Unit: %

– Designation: a

– Value range: ±16384 = ±100 %

– Resolution: 16 bits, scaling: ±16384 ¢ ±100 %

l Digital signals

– Symbol: 

– Unit: binary, with HIGH or LOW level

– Designation: d

– Resolution: 1 bit

l Speed signals

– Symbol: 

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

– Designation: phd

– Value range: ±2

− 1

– Resolution: 16 bit

l Angle signals

– Symbol: 

– Unit: inc

– Designation: ph

– Value range: ±2

− 1

– Resolution: 32 bits, scaling: 1 revolution ¢ 65536 inc

Only the same signal types can be connected with each other. Thus, an analog output signal of one

function block can only be connected to the analog output of the other function block. If two different

signal types are connected, the connection will be rejected.
