1.2.2 Preconditions
Memory configuration
Static NC memory
Memory space for curve tables in static NC memory is defined by machine data:
18400 $MN_MM_NUM_CURVE_TABS (number of curve tables)
18402 $MN_MM_NUM_CURVE_SEGMENTS (number of curve segments)
18403 $MN_MM_NUM_CURVE_SEG_LIN (number of linear curve segments)
18404 $MN_MM_NUM_CURVE_TABS (number of curve table polynomials)
Dynamic NC memory
Memory space for curve tables in dynamic NC memory is defined by machine data:
18406 $MN_MM_NUM_CURVE_TABS_DRAM (number of curve tables)
18408 $MN_MM_NUM_CURVE_SEGMENTS_DRAM (number of curve segments)
18409 $MN_MM_NUM_CURVE_SEG_LIN_DRAM (number of linear curve segments)
18410 $MN_MM_NUM_CURVE_POLYNOMS_DRAM (number of curve table polynomials)
1.3 Master value coupling
1.3.1 Function
The "master value coupling" function can be used to process short programs cyclically with
close coupling of the axes to one another and a master value that is either generated
internally or input from an external source.
The master value can for example be derived from a conveyor belt or a vertical shaft.
Either an axis or path master value coupling can be used, and activated and deactivated in
the NC parts program or by using a synchronous action.
Coupling with the master value is defined using a curve table.
1.3.2 Preconditions
The option "Master Value Coupling and Curve Tables Interpolation" or the relevant option of
generic coupling (refer to "Reconditions" for generic coupling) is a prerequisite for utilization
of the function.
