9.1 Product brief
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, MDI, 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, MDI, or JOG. This is ensured through the NC internal mode logic.
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
The following options are available for testing or moving in position a new part program.
• 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.
Block search
The block search function enables the following program simulations for locating specific program points:
• Type 1 without calculation at contour
• Type 2 with calculation at contour
• Type 4 with calculation at block end point
• Type 5 automatic start of the selected program point with calculation of all required data from history
• Automatic start of an ASUB after a block search
