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 (Page 139 ADVANCED
SYNCHRONOUS CONTROL INITIAL POSITION).
"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 power supply of the Motion module turns OFF

4.7 Synchronous Control Monitor Data
Storage details
• The current value after combining the main input and
sub input values from the main shaft is stored.
• Value is stored even after system's power supply OFF.
Refresh cycle: Operation cycle (During synchronous
control only)
• The position value per cycle after the main shaft gear
is stored.
• One cycle is considered the cam axis length per cycle.
• Value is stored even after system's power supply OFF.
Refresh cycle: Operation cycle (During synchronous
control only)
• The position value per cycle after the auxiliary shaft
gear is stored.
• One cycle is considered the cam axis length per cycle.
• Value is stored even after system's power supply OFF.
Refresh cycle: Operation cycle (During synchronous
control only)
• The current phase compensation amount is stored.
Refresh cycle: Operation cycle (During synchronous
control only)
• The position value per cycle is stored, which is
calculated from the input movement amount to the
cam axis. (The value after phase compensation)
• Value is stored even after system's power supply OFF.
Refresh cycle: Operation cycle (During synchronous
control only)
• The command position value as the cam reference
position is stored.
• Value is stored even after system's power supply OFF.
Refresh cycle: Operation cycle (During synchronous
control only)
• The command position value while controlling the cam
axis is stored.
• Value is stored even after system's power supply OFF.
Refresh cycle: Operation cycle (During synchronous
control only)
• The executing cam No. is stored.
Refresh cycle: Operation cycle (During synchronous
control only)
• The executing cam stroke amount is stored.
Refresh cycle: Operation cycle (During synchronous
control only)
