• Channelspecific frames and frames active in the channel for transforming closed
calculation rules into Cartesian coordinate systems. Offsets, rotations, scalings, and
mirrorings for geometry axes and special axes are programmed in a frame.

• Display of channelspecific alarm responses.
• Display of current machining sequence (axis position, current G functions, current
auxiliary functions, current program block) for each channel.
• Separate program control functions for each channel.
These functions (with the exception of the display functions) are controlled and checked by
the PLC with interface signals.
Channels in the same mode group always have to be operated in the same mode
(AUTOMATIC, JOG, MDA).
Channel configuration
The channels can be assigned individual channel names via machine data:
MD20000 $MC_CHAN_NAME (channel name)
.
The various axes are then assigned to the available channels via machine data. There can
be only one setpointissuing channel at a time for an axis/spindle. The axis/spindle actual
value can be read by several channels at the same time. The axis/spindle must be registered
with the relevant channel.
The following channelspecific settings can also be made using machine data:
• Reset states or initial programming settings of G-groups via machine data:
MD20150 $MC_GCODE_RESET_VALUES (reset state of G-groups)
• Auxiliary function groups for compilation and output timing
• Transformation conditions between machine axes and geometry axes
• Other settings for the execution of a part program
