Cam Data Operation Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Cam data operation function

This function is used to write/read cam data via buffer memory with the cam operation control data. To operate the points
more than the amount of data for each operation (as follows), the operation should be executed separately.
Cam data format
Stroke ratio data format
Coordinate data format
Cam operation control data
Setting item Setting details
[Cd.600] • Set the command for operating cam data.
Cam data operation • The Simple Motion module resets the value to "0"
