Synchronous Control Initial Position - Mitsubishi Electric QD77MS User Manual

5.1 Synchronous control initial position

The following synchronous control monitor data can be aligned to a set position when starting
synchronous control, as the initial position for synchronous control.
The alignment to a synchronous control initial position is useful for restoring a system based
on the last control status along with restarting synchronous control after canceling midway.
[Md.400] Current value after composite main shaft
[Md.401] Current value per cycle after main shaft
[Md.402] Current value per cycle after auxiliary
[Md.407] Cam axis current value per cycle
[Md.408] Cam reference position
[Md.409] Cam axis feed current value
