Using the position–dependent switching signals 1 and 2, cams can be
simulated without any mechanical equipment (e.g. at inaccessible posi-
tions), dependent on the actual position value.
The absolute cam switching positions are entered via parameter, and
the associated cam switching signals are output as output signal.
Notice
Only after the axis has been referenced, is it guaranteed that the cam
switching signals really do have a ”true” position reference when
output.
This means that an AND logic operation must be externally established
between the ”Reference point set/reference point not set” output signal
and the ”Cam switching signals 1, 2” output signals (e.g. using an
external PLC).

No.
Name Min. Standard Max. Units Effective
0310 Cam switching position 1 –200 000 000 0 200 000 000 MSR Immedi-

The cam switching positions 1 and 2 are set using these parameters.
The following assignment applies:
P0310 (cam switching position 1) ––> cam switching signal 1
P0311 (cam switching position 2) ––> cam switching signal 2
