Cam Data Operation Function - Mitsubishi Electric QD77MS User Manual

3.2.2 Cam data operation function

This function is used to write/read cam data via buffer memory with the cam operation control
data. The amount of data for each operation is 4096 points with the stroke ratio data format,
and 2048 points with the coordinate data format. If it is more than that, the operation should
be executed separately.
