2.2 Explanation of the logic
2.2.1 Embedding
If you parameterize the preconfigured application "Reversing starter" under
"Parameters > Configuration", the function blocks "Control station" and
"Protection/Control" are interconnected by default as per Figure 2-7.
Figure 2-7
To embed the logic for blockage prevention, the interconnection of the ON
commands has been separated. The authorized control commands "ON<", "ON>"
and "OFF" from "Control station" are fed into the logic as inputs (marked in green in
Figure 2-1 and Figure 2-8). The outputs of the logic are interconnected to the "ON"
plugs of "Protection/Control" (marked in orange in Figure 2-1 and Figure 2-8). The
enabled command "OFF" from Control station remains connected with the "OFF"
plug of "Protection/Control".
