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