Synchronous control
start
• Synchronous control begins if the target
axis bit is turned ON.
• Synchronous control ends if the bit is
turned OFF during synchronous control.
Fetch cycle: Operation cycle
Set the target axis in 16bits.
(bit0: axis 1 to bit15: axis 16
(Note-1)
)
OFF : Synchronous control end
ON : Synchronous control start
0 36320
[Cd.381]
Synchronous control
analysis mode
• If the target axis bit is turned ON and
synchronous control is started, the
analysis is only executed and the control
does not start.
Fetch cycle: At start of the synchronous
control
Set the target axis in 16bits.
(bit0: axis 1 to bit15: axis 16
(Note-1)
)
OFF : Synchronous control analysis
mode OFF
ON : Synchronous control analysis
mode ON
0 36322
(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.
Example
The following shows a procedure of aligning the synchronous position of an output axis
that references the input axis.
1) Set the following values in the synchronous control initial position parameters.

Setting value
[Pr.460] Setting method of current value per cycle after main
shaft gear
2: Calculate from input axis
[Pr.462] Cam axis position restoration object
2: Cam axis feed current value restoration
[Pr.463] Setting method of cam reference position
0: Previous value
[Pr.464] Setting method of cam axis current value per cycle
2: Current value per cycle after main shaft gear
2) Turn ON the target axis bit of "[Cd.381] Synchronous control analysis mode", and then
turn the target axis bit from OFF to ON in "[Cd.380] Synchronous control start" to start
the synchronous control analysis mode.
3) Verify the target axis bit is OFF for "[Cd.380] Synchronous control start", and execute
positioning for the output axis to be updated to "[Md.409] Cam axis feed current value".
4) Turn OFF the target axis bit of "[Cd.381] Synchronous control analysis mode", and
then turn the target axis bit from OFF to ON in "[Cd.380] Synchronous control start" to
start synchronous control.
