Starting/Ending For Synchronous Control - Mitsubishi Electric QD77MS User Manual

1.4.2 Starting/ending for synchronous control

Set the parameters for synchronous control for each output axis to start synchronous control.
The status changes to synchronous control after the parameters are analyzed at the start of
synchronous control, and the output axes synchronize with input axis operations.

(Note-1): The range from axis 1 to 2 is valid in the 2-axis module, from axis 1 to 4 is valid in the 4-axis module, from axis 1 to 8 is valid in the
8-axis module, and from axis 1 to 16 is valid in the 16-axis module.
Starting method for synchronous control
Synchronous control can be started by turning the target axis bit from OFF to ON in
"[Cd.380] Synchronous control start" after setting the parameters for synchronous control.
"5: Analyzing" is set in "[Md.26] Axis operation status" at the synchronous control start, and
the parameters for synchronous control are analyzed. The BUSY signal turns ON after
completion of analysis, and "15: Synchronous control" is set in "[Md.26] Axis operation
status".
Start the input axis operation after confirming that "15: Synchronous control" is set in
"[Md.26] Axis operation status".
Ending method for synchronous control
Synchronous control can be ended by turning the target axis bit from ON to OFF in
"[Cd.380] Synchronous control start" after the input axis operation is stopped.
The BUSY signal turns OFF at the synchronous control end, and "0: Standby" is set in
"[Md.26] Axis operation status" at the output axis stop.
Synchronous control can also be ended by turning the target axis bit from ON to OFF in
"[Cd.380] Synchronous control start" during the input axis operation. However, it is
recommended to end after stopping the input axis operation since the output axis stops
immediately.
Refer to Section 1.4.3 "Stop operation of output axis" at the synchronous control end.
