If a negative virtual master axis speed Z159.9– is selected, the cam is processed re-
versely.
Example for the calculation time of processing with a virtual master axis:
Count supporting points Z159.5– = 512
Virtual master axis speed Z159.9– = 216
Fieldbus task cycle time Z1.10– = 1 ms
In order to obtain the required speed, in order to process the cam in 0.4 sec,
the following is required:
4.6.5.3 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 (Z159.2– bit 5 = 0):
n Processing is executed cyclical (Z159.2– bit 5 = 0):
In order to process the AND operation in bit mode, the supporting point count
must comply with a power of 2 (for example 256 or 512).
