No. Description
④
Using machine data, you can control whether the previously determined track identifier bits of
tracks 0 to 12 of the cam controller are passed on, or whether they are set directly by the track
enable signal (TRACK_EN).
⑤
You enable the track signals of tracks 0 to 12 by setting TRACK_EN, and the count function by
setting CNTC0_EN / CNTC1_EN.
⑥
The track signal of track 3 and digital input I3 can be logically linked by an AND operation,
provided you have set this option in the machine data (EN_IN_I3).
⑦
All track and cam identifier bits can be read at this location (i.e., before these are logically
linked with machine and channel data) using the ACTPOS_EN or CAMOUT_EN job.
At tracks 3 to 31, the track identifier bit is equivalent to the track result (point 1).
⑧
After having been logically linked with the machine / channel data, the track signals of tracks 0
to 12 are available in the checkback signals. The track signals of tracks 13 to 31 and the track
identifier bits of point 7 are identical. The track signals of tracks 0 to 12 are also available at the
digital outputs Q0 to Q12.
