Number of cams
The number of cams available determines the cam cycle time and the maximum number of
assignable cams.
Number of cams Cam cycle time
16 cams 20.48 µs
32 cams 40.96 µs
64 cams 81.92 µs
128 cams 163.84 µs

Range:
0 = cam controller
1 = CPU
Bit number = track number
Bits 13 to 15 must be 0.
The machine data "activation of track outputs" defines how the track signals of tracks 0 to 12 are
activated. Tracks can be activated by:
 The cam controller: Track signals are activated and deactivated by the FM 352 cam processing
functions.
 CPU: The track signals represent the corresponding values of the track enables in the channel
DB.
This allows the explicit activation of track outputs in the user program.
