Read following axis value for specified leading axis value
(<master value>)
Read leading axis value for specified following axis value
(<following value>)
Define following axis minimum value:
• In the entire definition range of the curve table
or
• In a defined interval <a> to <b>
Define following axis maximum value:
• In the entire definition range of the curve table
or
• In a defined interval <a> to <b>
Number (ID) of curve table
The <gradient> parameter returns the incline of the curve table
function at the calculated position.
Axis whose motion is to be calculated using the curve table
(optional)
Axis providing the master values for the calculation of the following
axis motion (optional)
with CTABINV
Leading axis value:
• for reading the associated following axis value with CTAB
or
• for the selection of the curve segment with CTABSSV/CTABSEV
The assignment of a leading axis value to a following axis value
with CTABINV must not always be unique. CTABINV requires,
therefore, an approximate value for the expected leading axis
value as a parameter.
Lower limit of the master value interval with CTABTMIN/CTABTMAX
Upper limit of the master value interval with CTABTMIN/CTABTMAX
Note:
The master value interval <a> to <b> always has to be within the
curve table's definition range.
