Function
The CAM Control module features 24 digital outputs used for mapping cam tracks.
Run the "EFAS CAM-Creator" to write the cam program and save it on the fail-safe CAM Control module
memory.
The CAM Control module supports the following operating options:
Standalone
Together with a EFAS Controller optional EFAS modules and further EtherCAT slaves
Together with an EtherCAT master, a EFAS bus coupler and optional EFAS module plus further
EtherCAT slaves
