Description of the Software Modules and Parameters
If a negative virtual master axis speed
versely.
Example for the calculation time of processing with a virtual master axis:
Virtual master axis speed

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":
Index
Index
Count supporting points
Virtual master axis speed
Fieldbus task cycle time
Processing time
In order to obtain the required speed, in order to process the cam in 0.4 sec,
the following is required:
= Count_Supporting points 256
Virtual master axis speed
Index = Parameter value Base value (P159.14)
n Processing is executed once, only

= Parameter value Base value (P159.14)
n Processing is executed cyclical
Mask = 0xFFFFFFFF >> 32
 
= Parameter value Base value (P159.14)
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).
