The memory areas for user data in the NC are preset to suit most user require-
ments during an NCK general reset. The following areas can be adjusted to
achieve optimum utilization of the available user memory:
S
Tool management
S
Tool offsets
S
User variables
S
R parameters
S
Compensations (e.g. LEC)
S
Protection zones
S
Frames
The memory must be sectionalized before commencement of the actual start-up
process because all buffered user data (e.g. part programs, drive data) are lost
when the memory is re-allocated. Machine data, setting data and options are
not erased.
The MDs for the memory configuration are activated by power ON.
