Data Required For Major Positioning Control - Mitsubishi Electric MELSEC-L LD75P User Manual

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".
Setting item
[Da.1] Operation pattern
[Da.2] Control system
[Da.3] Acceleration time No.
[Da.4] Deceleration time No.
[Da.5] Axis to be interpolated
Positioning
[Da.6]
address/movement amount
Positioning data
[Da.7] Arc address
[Da.8] Command speed
[Da.9] Dwell time
[Da.10] M code
M code ON signal output
[Da.27]
timing
[Da.28] ABS direction in degrees
Interpolation speed
[Da.29]
designation method
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.
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)
Set the control system defined as a "major positioning control". ( Page 339, Section 9.1)
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.)
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.)
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)
Set the target value during position control. ( Page 352, 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 the M code ON signal output timing for each positioning data.
Set the ABS direction in degrees for each positioning data.
Set the interpolation speed designation method for each positioning data.
