1.4 Operation method of synchronous control

1.4.1 Synchronous control execution procedure

The synchronous control is executed using the following procedure.
Preparation
STEP 1
Refer to Chapter 2
Refer to Chapter 3
Refer to Chapter 4
and Section 5.2
STEP 2
Refer to
Appendices
STEP 3

Complete
STEP 6
synchronous
control
Set the following parameters.
Positioning parameters
Expansion parameters
Set "input axis parameters" for synchronous
control .
( Pr.300 to Pr.304 , Pr.320
Set the cam data.
Set "synchronous parameters" for 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 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
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
REMARK
• Mechanical elements such as limit switches are considered as already installed.
• Parameter settings for positioning control apply for all axes with the Simple Motion
module.
• 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.
<Method 1>
Directly set (write) the parameters in the Simple Motion
module using GX Works2.
<Method 2>
Set (write) the parameters from the PLC CPU to
to Pr.329 )
the Simple Motion module using the program.
Turn ON the target axis bit in
" Cd.380
