Starting/Ending For Synchronous Control - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Starting/ending for synchronous control

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

Setting item Setting details
[Cd.380] • Synchronous control begins if the target axis bit
Synchronous is turned ON.
control start • Synchronous control ends if the bit is turned
OFF during synchronous control.
Fetch cycle: Operation cycle
*1 When the synchronous control analysis mode is executed simultaneously or the synchronous control analysis mode and the
synchronous control start are executed simultaneously for multiple axes, perform the setting for the synchronous control start in batches
for each word. If the axes are set continuously in bits, the synchronous control analysis mode and the synchronous control start may not
operate depending on the timing.
*2 The range from axis 1 to 4 is valid in the 4-axis module and from axis 1 to 8 is valid in the 8-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 advanced synchronous control parameters.
"5: Analyzing" is set in "[Md.26] Axis operation status" at the synchronous control start, and the advanced synchronous control
parameters are analyzed. "[Md.141] BUSY" 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.
"[Md.141] BUSY" 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 the following for the stop operation of output axis at the synchronous control end.
