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". (Refer to Section 9.2 "Setting the positioning data".)
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 system 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 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. (Refer to
Section 9.1.6.)
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 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.
Major positioning control sub functions
Refer to Section 3.2.4 "Combination of QD75 major functions and sub functions"
for details on "sub functions" that can be combined with the major positioning
control.
Also refer to CHAPTER 12 "CONTROL SUB FUNCTIONS" for details on each sub
function.
Major positioning control from peripheral devices
"Major positioning control" can be executed from the peripheral device test mode.
Refer to GX Configurator-QP Operating Manual for details on carrying out major
positioning control from the peripheral device.
REMARK

600 positioning data (positioning data No. 1 to 600) items can be set per axis.
