9 MAJOR POSITIONING CONTROL
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 Setting details
Positioning dat
a N
o. 1
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. (Refer to Section 9.1.2.)
Da.2 Control system
Set the control system defined as a "major positioning control". (Refer to 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. (Refer to
Section 9.1.6.)
Da.6
Positioning address/
movement amount
Set the target value during position control. (Refer to 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.
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".)
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.
