If a negative virtual master axis speed
is selected, the cam is processed re-
versely.
Example for the calculation time of processing with a virtual master axis:
Count supporting points
= 512
Virtual master axis speed
= 216
Fieldbus task cycle time
= 1 ms
In order to obtain the required speed, in order to process the cam in 0.4 sec,
the following is required:
3.6.5.3 Parameter-controlled processing
With parameter-controlled processing, the table index is specified by an input parameter
and is adjusted by an accordant parameterization.
Index calculation is made as follows:
m
Input parameters - type "Float":
m
Input parameters - type "Integer":
n
Processing is executed once, only (
bit 5 = 0):
n
Processing is executed cyclical (
bit 5 = 0):
In order to process the bitwise AND in this case, the supporting point count
must comply with a power of 2 (for example 256 or 512).
