9.1.1
Data required for major positioning control
The following table shows an outline of the "positioning data" configuration and setting details required to carry out the
"major positioning controls".
The settings and setting requirement for the setting details of [Da.1] to [Da.10] and [Da.27] to [Da.29] differ according
to the "[Da.2] Control system". (

Page 364, Section 9.2)
(1) Major positioning control sub functions
Refer to

Page 59, Section 3.2.5 for details on "sub functions" that can be combined with the major
positioning control.
Also refer to

Page 507, CHAPTER 12 for details on each sub function.
(2) Major positioning control from GX Works2
"Major positioning control" can be executed by test function of GX Works2.
Refer to

Page 756, Appendix 6.5 for details on carrying out major positioning control from GX Works2.
Remark
600 positioning data (positioning data No. 1 to 600) items can be set per axis.
Setting item Setting details
Positioning data
[Da.1] Operation pattern
Set the method by which the continuous positioning data (Ex: positioning data No. 1, No. 2, No.
3

) will be controlled. (  Page 342, Section 9.1.2)
[Da.2] Control system Set the control system defined as a "major positioning control". (

Page 339, Section 9.1)
[Da.3] Acceleration time No.
Select and set the acceleration time at control start. (Select one of the four values set in [Pr.9],
[Pr.25], [Pr.26], and [Pr.27] for the acceleration time.)
[Da.4] Deceleration time No.
Select and set the deceleration time at control stop. (Select one of the four values set in [Pr.10],
[Pr.28], [Pr.29], and [Pr.30] for the deceleration time.)
[Da.5] Axis to be interpolated
Set an axis to be interpolated (partner axis) during the 2-axis interpolation operation and a
circular interpolation axis during the 3-axis helical interpolation control.
(
 Page 359, Section 9.1.6)
[Da.6]
Positioning
address/movement amount
Set the target value during position control. (  Page 352, Section 9.1.3)
[Da.7] Arc address Set the sub point or center point address during circular interpolation control.
[Da.8] Command speed Set the speed during the control execution.
[Da.9] Dwell time
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).
[Da.10] M code
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.
[Da.27]
M code ON signal output
timing
Set the M code ON signal output timing for each positioning data.
[Da.28] ABS direction in degrees Set the ABS direction in degrees for each positioning data.
[Da.29]
Interpolation speed
designation method
Set the interpolation speed designation method for each positioning data.
