The following table shows an outline of the "positioning data" configuration and setting
details required to carry out the "major positioning controls".
Set the method by which the continuous positioning data (Ex: positioning data No.1,
No.2, No.3) will be controlled. (Refer to Section 9.1.2.)
Set the control method defined as a "major positioning control". (Refer to Section 9.1.)
Select and set the acceleration time at control start. (Select one of the four values set
in

Set an axis to be interpolated (partner axis) during the 2-axis interpolation operation
(Refer to Section 9.1.6.).
LD77MS4
Set the target value during position control. (Refer to Section 9.1.3.)
Set the sub point or center point address during circular interpolation control.
Set the speed during the control execution.
The time between the command pulse output is completed to the positioning
completed signal is turned ON. Set it for absorbing the delay of the mechanical system
to the instruction, such as the delay of the servo system (deviation).
Set this item when carrying out sub work (clamp and drill stops, tool replacement, etc.)
corresponding to the code No. related to the positioning data execution.
Set an axis to be interpolated during the 2- to 4-axis interpolation operation.

Major positioning control sub functions
Refer to Section 3.2.5 "Combination of LD77MS main functions and sub functions"
for details on "sub functions" that can be combined with the major positioning
control.
Also refer to Chapter 13 "Control Sub Functions" for details on each sub function.
Major positioning control from GX Works2
"Major positioning control" can be executed by test function of GX Works2.
Refer to "Simple Motion Module Setting Tool Help" of GX Works2 for details on
carrying out major positioning control from the GX Works2.
