Cam data structures
5.7.2 SMC_CAMXYVA
An XYVA cam consists of an array of SMC_CAMXYVA. Each variable of that array describes
a point on the cam using dX (master position), dY (slave position), dV (first derivative dY/
dX; corresponds to the slave velocity at constant master velocity 1) and dA (second
derivative d²Y/dX²; corresponds to the slave acceleration at constant master velocity 1).
The start and end points of the cam must always be included.
5.7.3 SMC_CAMTable_<Variable type>_<Number of elements>_1
An equidistant cam table is described in this data structure. The individual slave positions
are stored in Table: ARRAY[0..<Number of elements>-1] OF <Variable type>. The start and
end points of the cam must always be included.
The variables fEditorMasterMin, fEditorMasterMax, fTableMasterMin, fTableMasterMax
describe an additional scaling of the tables, whereby the range of definitions/values is
stored in SoftMotion units (fEditorMaster, fEditorSlave) and scaled on table units
(fTableMaster, fTableSlave).
5.7.4 SMC_CAMTable_<Variable type>_<Number of elements>_2
A non-equidistant cam table is stored in Table: ARRAY[0..<Number of elements>-1] OF
ARRAY[0..1] OF <Variable type>. In contrast to the equidistant format, the first element is
the master position and the second is the slave position.
