3.6 "Output Cam" technology object
Use the "Output cam" technology object to generate switching
signals based on the axis position. The switching signals can be
output to the integrated outputs of the technology CPU or to the
outputs of a standard slave at DP(DRIVE.
The Technology CPU distinguishes between the cams listed below:
• Position-based cam
Position-based cams are set when the ON position is reached, and reset when
the OFF position is reached.
• Switching cams
Switching cams are set when the ON position is reached and must be reset in
the user program.
• Time-based cam
Time-based cams are set for the duration of a defined pulse period when the
ON position is reached.
Interconnections
The "Cam" technology object can be interconnected with the following technology
objects:
• Positioning axes
• Synchronization axes
• External encoders
