Synchronous Control Monitor Data - Mitsubishi Electric QD77MS User Manual

4.7 Synchronous control monitor data

Synchronous control monitor data is updated only during synchronous control.
The monitor values ([Md.400], [Md.401], [Md.402], [Md.407], [Md.408], and [Md.409]) from
the last synchronous control session are restored the next time the system's power supply
turns ON. Restarting operation status from the last synchronous control session is possible
through returning to the last position via positioning control (Refer to Chapter 5).
"The last synchronous control session" indicates status just before the last synchronous
control session was stopped as follows. These are listed with the last synchronization status.
• Just before "[Cd.380] Synchronous control start" turns from ON to OFF.
• Just before deceleration stop by a stop command or an error, etc.
• Just before the system's power supply turned OFF to the Simple Motion module.
