9.2 Curve tables (CTAB)
<m>
<memory
location>
If CTABLOCK/CTABUNLOCK is programmed without specification of the curve table to be
locked/unlocked, then all curve tables or all curve tables in the specified memory will be
locked/unlocked:
CTABLOCK()
CTABLOCK(,,"SRAM")
CTABLOCK(,,"DRAM")
CTABUNLOCK()
CTABUNLOCK(,,"SRAM")
CTABUNLOCK(,,"DRAM")
588
When a curve table range
CTABLOCK(<n>,<m>)/CTABUNLOCK(<n>,<m>) is
locked/unlocked, <m> is used to specify the number of the last curve
table in the range.
<m> has to be greater than <n>.
Specification of memory location (optional)
In the case of locking/unlocking without a memory location being
specified, the specified curve tables are locked/unlocked in the static
and the dynamic NC memory.
In the case of locking/unlocking with a memory location being
specified, of the specified curve tables, only those located in the
specified memory location are locked/unlocked. The rest are not
locked/unlocked.
"SRAM"
Lock/unlock in the static NC memory
"DRAM"
Lock/unlock in the dynamic NC memory
Locks all curve tables in the static and the dynamic NC
memory
Locks all curve tables in the static NC memory
Locks all curve tables in the dynamic NC memory
Unlocks all curve tables in the static and dynamic NC
memory
Unlocks all curve tables in the static NC memory
Unlocks all curve tables in the dynamic NC memory
