For the ”position–related switching signals (cams)” function, the simulated cam signal is output via these
output signals.

Note:
 Only after the axis has been referenced can it be guaranteed that the cam switching signals have a
”true” position reference when they are output.
This is the reason that an external AND logic operation must be established between the output sig-
nal ”reference point set/no reference point set” and the output signals ”cam switching signals 1,2”
(e.g. using an external PLC).
 The function ”position–related switching signals (cams)” is described in Chapter 6.2.3.
