Detailed description
2.2 Curve tables
Access to curve table segments
• Read start value (following axis value) of a table segment
• Read end value (following axis value) of a table segment
Note
If curve table functions such as CTAB(), CTABINV(), CTABSSV() etc., in synchronous
actions are used, only main traverse variable, e.g. $AC_PARAM[ ... ] or $R[ ... ] is
permissible for the return value and the argument "degrees" of the function.
Example:
ID=1 WHEN TRUE DO $R1 = CTABSSV(10, 1, $R2)
or
ID=1 WHEN TRUE DO $AC_PARAM[1] = CTABSSV(10, 1, $AC_PARAM[2])
Enable/cancel blocking
The following functions can be used to enable or cancel deletion and overwrite blocks for
parts. programs.
• Enable deletion and overwrite block.
• Cancel deletion and overwrite block.
CTABUNLOCK releases the tables locked with CTABLOCK. Tables involved in an active
coupling remain locked, i.e. they cannot be deleted. However, the CTABLOCK command
is cancelled, i.e. the table can be deleted as soon as the coupling is deactivated. It is not
necessary to call CTABUNLOCK again.
General form: CTABUNLOCK(n, m, memType)
Applications of the forms:
Curve table with number n
CTABLOCK(n)
Curve tables in the number range n to m.
CTABLOCK(n, m)
All curve tables, irrespective of memory type
CTABLOCK()
All curve tables in the specified memory type
CTABLOCK(, , memType)
Curve table with number n
CTABUNLOCK(n)
32
CTABSSV(leading value, n, degrees, [following axis, leading axis])
CTABSEV(master value, n, degrees, [following axis, master axis])
General form: CTABLOCK(n, m, memType)
Special functions: Axis Couplings and ESR (M3)
