1.3 Operation Method of Synchronous Control

Set the following parameters.
• Common parameters ([Pr.24], [Pr.82], [Pr.89],
[Pr.96], [Pr.97], [Pr.150] to [Pr.153])
• Positioning parameters ([Pr.1] to [Pr.4],
[Pr.7] to [Pr.22], [Pr.25] to [Pr.42], [Pr.81],
[Pr.83], [Pr.84], [Pr.90], [Pr.95],
[Pr.116] to [Pr.119], [Pr.122], [Pr.123])
• Extended parameters ([Pr.91] to [Pr.94])
Set "input axis parameters" for advanced
synchronous control.
RD77MS: [Pr.300] to [Pr.304], [Pr.320] to [Pr.329]
RD77GF: [Pr.300] to [Pr.304], [Pr.320] to [Pr.329],

[Pr.710] to [Pr.714], [Pr.1010] to [Pr.1013]
*2 Set the cam data.
Set "synchronous parameters" for advanced
*3
synchronous control. ([Pr.400] to [Pr.468])
Create a program that executes to start / change
control / stop synchronous control.
(Set "[Cd.380]Synchronous control start", start and
*4
stop the input axis operation and change the
reduction ratio)
Write the program, which is created
in STEP1 and STEP2, to the CPU module.
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 status.
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
One of the following two methods can be used.
<Method 1>
Directly set (write) the parameters
in the Simple Motion module using
the engineering tool.
<Method 2>
Set (write) the parameters from
the CPU module to the Simple
Motion module using the program.
Turn ON the target axis bit in
"[Cd.380] Synchronous control start"
and start 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 the engineering tool.
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
"[Cd.380] Synchronous control start"
to stop synchronous control
by the program in STEP 2.
