Returns the table number entered as the <p>th curve table in the
specified memory.
Example:
CTABID(1,"SRAM") returns the number of the first curve table in
the static NC memory. In this context the first curve table is the curve
table with the highest table number.
Note:
If the sequence of curve tables in the memory changes between
consecutive calls of CTABID, e.g. due to the deletion of curve tables
with CTABDEL, CTABID(<p>,...) can return a different curve table
with the same number <p>.
Returns the lock state of curve table number <n>:
0 Table is not locked
1 Table is locked by CTABLOCK
2 Table is locked by active coupling
3 Table is locked by CTABLOCK and active coupling
-1 Table does not exist
Returns the memory location of curve table number <n>:
0 Table in the static NC memory
1 Table in the dynamic NC memory
-1 Table does not exist
Returns the periodicity of curve table number <n>:
0 Table is not periodic
1 Table is periodic in the leading axis
2 Table is periodic in the leading and following axes
-1 Table does not exist
Entry number in memory
Number (ID) of curve table
Specification of memory location (optional)
Static NC memory
"SRAM"
Dynamic NC memory
"DRAM"
Note:
If a value is not programmed for this parameter, the default memory
location set with
MD20905 $MC_CTAB_DEFAULT_MEMORY_TYPE is used.
