Path traversing behavior
9.3 Curve tables (CTAB)
Parameters
CTAB
CTABINV
CTABSSV
CTABSEV
Faxis
Laxis
n, m
Degrees
ApproxMasterValue
• CTABSSV, CTABSEV
CTABSSV can be used to read the starting value of the curve segment that belongs to the
specified master value. CTABSSV can be used to read the end value of the curve segment
that belongs to the specified master value.
• Trailing or leading position derived from curve table with CTAB, CTABINV
R10 = CTAB(LV, n, degree, Faxis,
Laxis)
R10=CTABINV(FV, approxLV, n, degrees,
Faxis, Laxis)
• Determining the segments of the curve table by specifying a master value with
R10 = CTABSSV(LV, n, degrees, Faxis,
Laxis)
R10 = CTABSEV(LV, n, degrees, Faxis,
Laxis)
9-28
CTABSSV, CTABSEV
Read a following value directly from a master value.
Read the master value for a following value.
Read the start value of the curve segment for a following
axis.
Read the end value of the curve segment for a following axis.
Following axis
Axis that is programmed via the curve table.
Leading axis
Axis that is programmed with the master value.
Numbers for curve tables.
Curve table numbers can be freely assigned. They are used
exclusively for the unique identification.
Gradient for incline at start or end of segment in curve
table
The position value of the expected approximation value that
can be used to determine a unique master value.
Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Following value for a master value
Master value to a following value
Starting value of the following axis in
the segment belonging to the LV
End value of the following axis in the
segment belonging to the LV
