Incline of the curve table function
The output of the gradient (<gradient>) makes it possible to calculate the velocity of the leading
or following axis at the corresponding position.
Specification of the leading or following axis
The optional specification of the leading and/or following axis is important if the leading and
following axes are configured in different length units.
CTABSSV, CTABSEV
The CTABSSV and CTABSEV commands are not suitable to query programmed segments in
the following cases:
● Circles or involutes are programmed.
● Chamfering or rounding with CHF/ RND is active
● Smoothing with G643 is active
● NC block compression (COMP...) is active.
3.16.2.7 Curve tables: Check use of resources (CTABNO, CTABNOMEM, CTABFNO,
CTABSEGID, CTABSEG, CTABFSEG, CTABMSEG, CTABPOLID, CTABPOL,
CTABFPOL, CTABMPOL)
The programmer can use these commands to obtain up-to-date information about the use of
resources for curve tables, table segments, and polynomials.

Meaning
CTABNO: Determine the total number of defined curve tables (in the static and the dy‐
namic NC memory)
CTABNOMEM: Determine the number of defined curve tables in the specified <memory
location>
CTABFNO: Determine the number of curve tables remaining possible in the
specified <memory location>
CTABSEGID: Determine the number of curve segments of the specified <segment type>
used by curve table number <n>
