Cam Auto-Generation Function - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Cam auto-generation function

The cam auto-generation function is used to generate cam data automatically for specific purposes based on parameter
settings.
With this function, cam data is generated in the cam open area.
It is possible to generate up to 1 Mbyte including the regular cam data. (Example: 64 cam data (with the stroke ratio format,
resolution is 4096) can be automatically generated.)
The processing time of cam auto-generation takes longer if the data point is larger. Also, the real processing time changes by
status of axis start etc.

format)
