Cam Auto-Generation Function - Mitsubishi Electric QD77MS User Manual

3.2.3 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: 256 cam
data (with the stroke ratio format, resolution is 1024) 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.

(Note-1): With the exception of positioning control, main cycle processing is executed during the next available time. It changes by status of
axis start.
[Cd.608] Cam auto-generation request
Set "1: Cam auto-generation request" to execute cam auto-generation.
Cam data is generated in the cam open area of the specified cam No. based on the cam
auto-generation data.
The setting value is reset to "0" automatically after completing the process.
The cam auto-generation data is saved in the cam storage area. The cam auto-generation
is executed automatically again when the next power supply turns ON or PLC READY
signal [Y0] OFF to ON.
If a warning occurs when requesting cam auto-generation, the warning number is stored in
"[Md.24] Axis warning No." of axis 1, and the setting value is reset to "0" automatically.
When another request command is set, this function does not get executed and the setting
value is reset to "0" automatically.
