The static NC memory contains an active and passive file system.
Active file system
The active file system contains system data used to parameterize the NCK:
● Machine data
● Setting data
● Option data
● Global user data (GUD)
● Tool-offset/magazine data
● Protection zones
● R parameters
● Work offsets/FRAME
● Sag compensations
● Quadrant error compensation
● Leadscrew error compensation
This data represents the current work data of the NCK.
The user's view of the active file system is data-oriented.
Passive file system
The passive file system contains all files loaded onto the NCK:
● Main programs
● Subprograms
● Global-user-data and macro definition files (*.DEF)
● Standard cycles
● User cycles
● Workpieces
● Comments
The user's view of the passive file system is file-oriented.
