Function
Every channel behaves like an independent NC. A maximum of one
part program can be processed per channel.
• Control with one channel:
One mode group exists.
• Control with several channels:
Channels can be grouped to form several "mode groups."
Example:
Control with 4 channels, where machining is carried out in 2
channels and 2 other channels are used to control the transport of
the new workpieces.
Mode Group1
Mode Group2
Technologically-related channels can be combined to form a mode
group.
Axes and spindles of the same mode group can be controlled by one
or more channels.
An operating mode group is in one of "Automatic", "JOG" or "MDI"
operating modes, i.e., several channels of an operating mode group
can never assume different operating modes.
Channel status via symbol
The channel status and the channel operational messages are output
with
symbols in the channel status line:
Channel status
Channel interrupted
Channel active
Channel RESET
Channel operational messages
Stop: Action is required
(e.g., cancel feed disable).
