Channel
An NC channel represents the smallest unit for manual traversing of axes and automatic
processing of part programs. At any one time, a channel will always be in a particular mode,
e.g., AUTOMATIC, MDA, or JOG. A channel can be regarded as an independent NC.
Mode group
A channel always belongs to a mode group. A mode group can also consist of several
channels. A mode group can be identified by the fact that all channels of the mode group are
always in the same mode at a particular time, e.g., AUTOMATIC, MDA, or JOG. This is
ensured by the internal mode logic of the NC.
A mode group can be regarded as an independent multi-channel NC.
Channel gaps
When channels are configured, placeholder channels can be provided in order to create as
uniform a configuration as possible over machines in a series. Only the channels that are
actually used are then activated.
Program test
For purposes of testing or breaking in a new part program, the following options are available
for reducing critical situations while still in the testing phase:
• Program execution without setpoint outputs
• Program execution in singleblock mode
• Program execution with dry run feedrate
• Skip part program blocks
• Block search with or without calculation.
