1.4 Operation method of synchronous control
1.4.1 Synchronous control execution procedure
The synchronous control is executed using the following procedure.
Refer to Chapter 2
Refer to Chapter 3
Refer to Chapter 4
and Section 5.2
Set the following parameters.
Set "input axis parameters" for synchronous
Set the cam data.
Set "synchronous parameters" for synchronous
Create a program that executes to
start / change control / stop synchronous
Synchronous control start",
start and stop the input axis operation and
change the reduction ratio)
Write the program, which is created in
STEP1 and STEP2, to the PLC CPU.
Turn ON the synchronous control start bit for
the axis that starts synchronous control.
Verify that it is during synchronous control.
Operate the input axis.
Monitor the synchronous control operation
Execute the control change for the speed
change ratio, cam No., etc.
Stop the input axis.
Verify the input axis is stopped and turn OFF
the synchronous control start bit for the axis
that stops synchronous control.
End of control
• Mechanical elements such as limit switches are considered as already installed.
• Parameter settings for positioning control apply for all axes with the Simple Motion
• Be sure to execute the OPR when the OPR request flag is ON.
Chapter1 Outline of Synchronous Control
One of the following two methods can be used.
Directly set (write) the parameters in the Simple Motion
module using GX Works2.
Set (write) the parameters from the PLC CPU to
the Simple Motion module using the program.
Turn ON the target axis bit in
synchronous control by the program in STEP 2.
Verify that it is during synchronous control in
Md.26 Axis operation status
Operate the input axis by the program in STEP 2.
Monitor using GX Works2.
Changing the control by the program in STEP 2.
Stop the input axis by the program in STEP 2.
Turn OFF the target axis bit in
control by the program in STEP 2.
