4.6.5.4 Setting options of cam generator
Cyclical processing
1 Time controlled processing modes
If cyclical processing is selected in parameter Z159.2–, the cam generator jumps back
to the first table index after reaching the maximum table index Z159.4–. The cam gen-
erator then restarts processing. For more information, referring to the cyclical curve off-
set at a table index jump see chapter ZCyclical curve offset– on page 429.
2 Parameter-controlled processing mode
If the input parameters are float parameters, then the selection of the cyclical process-
ing does not effectuate the behavior of float parameters as described in chapter
ZParameter-controlled processing– on page 427.
Additionally to the base value Z159.14– and to the shift factor Z159.15– at the input
parameters of an integer data type, a mask is generated to specify the index. This acts
on the input parameters. This mask operates after subtraction of the base value and
after shift operation. Referring to mask operation only those bits are used to specify the
index, which are required to activate the curve index.
Example:
Initial situation: Value input parameter = 0x0075AB39 
Base value Z159.14– = 0xA000 
Shift factor Z159.15– = 7 
Count supporting points Z159.5– = 512
The following index results after subtraction of base value and after shift operation:
Having 512 supporting points applies to 512 = 2
9
. Therefore, 9 bits are required to re-
spond to the 512 supporting points of the cam. This mask, which contains 9 bits is gen-
erated by the controller. If there were 256 supporting points, then in conclusion the
mask will have 8 bits.
Example:
Index 22 is the active table index.
If the cyclical processing is not selected, the active table index is the index 0xEA16 =
59926. This index is greater than the maximum index of (count supporting points - 1)
= 511. The active table index is limited to a maximum index of 511 at non-cyclical pro-
cessing.
