14.2 Curve tables
● Maximum number of possible curve segments in memory memType.
CTABMSEG(memType, segType)
● Number of polynomials already used in memory memType.
CTABPOL(memType)
● Number of curve polynomials used by curve table number n.
CTABPOLID(n)
● Number of still possible polynomials in memory memType.
CTABFPOL(n)
● Maximum number of possible polynomials in memory memType.
CTABMPOL(n)
Boundary values of curve tables
Behavior of the leading axis/following axes on the edges of the curve table:
● The value at the beginning of the curve table is read by a following axis.
CTABTSV(n, degrees, F axis), following value at the beginning of the curve table
● The value at the end of the curve table is read by a following axis.
CTABTEV(n, degrees, FAxis), following value at the end of the curve table
● The value at the beginning of the curve table is read by the leading axis.
CTABTSP(n, degrees, FAxis), master value at the beginning of the curve table
● The value at the end of the curve table is read by the leading axis.
CTABTEP(n, degrees, FAxis), master value at the end of the curve table
● Determine the value range of the following value.
CTABTMIN(n, FAxis), minimum following value of curve table
CTABTMAX(n, FAxis), maximum following value of the curve table
Parameter
● Following axis:
Name of axis via which the following axis is programmed in the definition.
● Leading axis:
Name of axis via which the leading axis is programmed.
● n, m
Numbers for curve tables.
Curve table numbers can be freely assigned. They are used exclusively to uniquely identify
a curve table.
In order to delete a curve table area using the command CTABDEL(n, m) must be greater
than n.
● p
Entry location (in memType memory area)
