2.9 Channel-specific programming

2.9 Channel-specific programming
The NC area of the SINUMERIK 880 control is broken down into several channels.
Each channel has its own block preparation feature, which combines data from the part pro-
gram with NC data such as zero offsets, tool offsets etc. and transfers it to the interpolator via
a buffer memory.
The NC area is divided into different channels. These NC channels are combined to form
.
mode groups Channel assignment to these groups is specified by machine data. Depending
on the workpiece involved, machining programs can be generated for all channels and these
are entered into the central NC program memory.
SINUMERIK 880, SW 6 can be divided into a maximum of 16 channels.
SINUMERIK 880 GA2, SW 1 can be divided into a maximum of 8 channels chosen from 1 to
16. The following channels can be activated, for example:
• Channels 1 to 8
• Channels 5 to 12
• Channels 9 to 16
• Channels 1, 4, 7, 9, 10, 14, 15, 16
The basic versions of SINUMERIK 880, SW 6, and SINUMERIK 880 GA2, SW 1, comprise 4
channels.
