Function
l Interconnection of function blocks
l Encoder settings in single unit steps
l Set stretching factor through 6 decades
7.6.22.1 Interconnection of function blocks
The function block is connected directly behing the digital frequency input DFIN.
Stop!
The DFIN code C0425 must be set to selection 6 to evaluate the encoder signals correctly.
7.6.22.2 Encoder adaptation
The encoder is adapted to the controller using the freely adjustable encoder constants
