The PG 674 as a programmimg device

4.6.10 Programming cams

You may allocate "any" number of cams to each output. The
limit is set by the encoder resolution. A cam consists of a
switching-on and the corresponding switching-off position of
the output. Program the cams either by entering the output
switching points via the numeric key pad or by using the teach-
in method.

Cam numbering

The cams are numbered consecutively from 0 to n for every out-
put. The numbers are assigned to the rising pulse edges in as-
cending order. This means that i.e. a cam which is switched on
at position 10 has a smaller number than the cam which is
switched on at position 15.

We strictly advise you against programming cams while
the machine is running. Doing so could lead to undefined
switching states that are dangerous to both man and
machine.

Programming cams using the numeric key pad

Example:
- output O0.05: cam ON = 155, cam OFF = 275
