1.13 Program coordination
Channels
A channel can process its own program
independently of other channels. It can control
the axes and spindles temporarily assigned to it
via the program.
Two or more channels can be set up for the
control during startup.
Program coordination
If several channels are involved in the
machining of a workpiece it may be necessary
to synchronize the programs.
Special instructions (commands) are available
for program coordination. Each instruction is
programmed separately in a block.
