Position Data Table Configuration with XG-PM

Video Tutorial

 

The Position Data table in XG-PM is used to setup various axis movement. Each built-in Axis of the XEM CPU can have 400 entries in the Position data table.

The Position table is setup in the XG-PM software.

Step Action
1

Open the XG5000 project for the application. Go to Tools menu è Position Control to open XG-PM software.
2 Open the XG-PM project or connect to PLC and select Project è Open From PLC...
3

Open the Position data table in the Workspace for the axis that is being configured.

This example shows Axis #1.

Control Type

Control Type determines the type of movement for a step in the Position data table.

Control Type Description
ABS, (SNG)POS Absolute Positioning of a single axis.
ABS, (SNG)SPD Speed Control for a single axis. This or INC, (SNG)SPD can be used for Speed Control.
ABS, (SNG)FEED FEED Control for a single axis. This or INC, (SNG)FEED can be used for FEED Control.
ABS, (LIN)INT Absolute Linear interpolation movement command.
ABS, (CIR)INT Absolute Circular interpolation movement command.
INC, (SNG)POS Relative Positioning of a single axis.
INC, (SNG)SPD Speed Control for a single axis. This or ABS, (SNG)SPD can be used for Speed Control.
INC, (SNG)FEED FEED Control for a single axis. This or ABS, (SNG)FEED can be used for FEED Control.
INC, (LIN)INT Relative Linear interpolation movement command.
INC, (CIR)INT Relative Circular interpolation movement command.

Operation Type

Operation Type handles what to do after the movement is finished. The Operation Type changes meaning based on the Control Type Selected.

Operation Type Description
SNG, END Finish after the completion of the current step position control.
SNG, KEEP Continue to the next step after the completion of the current step position control.
SNG, CONT Continue to the next step continuously without stop.
REP, END Change the step number to the Repeat step number after the completion of the current step position control.
REP, KEEP Continue to the repeat step number after the completion of the current step position control.
REP, CONT The current step and the repeat step number continuously without stop.
Operation Type Description
SNG, END Speed control using current step's DATA.
SNG, KEEP Speed control using current step's DATA. If VTP command executed, continue to the next step after the completion of the current step's positioning.
SNG, CONT Not supported. Will give an error.
REP, END Speed control using current step's DATA.
REP, KEEP Speed control using current step's DATA. If VTP command executed, continue to the repeat step No. after the completion of the current step's positioning.
REP, CONT Not supported. Will give an error.
Operation Type Description
SNG, END Finish after the completion of the current step’s FEED control.
SNG, KEEP Continue to the next step after the completion of the current step FEED control.
SNG, CONT Not supported. Will give an error.
REP, END Change the step number to the Repeat step number after the completion of the current step FEED control.
REP, KEEP Continue to the repeat step number after the completion of the current step FEED control.
REP, CONT Not supported. Will give an error.
Operation Type Description
SNG, END Finish after the completion of the current step’s linear interpolation.
SNG, KEEP Continue to the next step after the completion of the current step’s linear interpolation.
SNG, CONT Continue to the next linear interpolation step continuously without stop.
REP, END Change the step number to the Repeat step number after the completion of the current step linear interpolation.
REP, KEEP Continue to the repeat step number after the completion of the current step’s linear interpolation.
REP, CONT The current linear interpolation and the repeat step number continuously without stop.
Operation Type Description
SNG, END Finish after the completion of the current step’s circular interpolation.
SNG, KEEP Continue to the next step after the completion of the current step’s circular interpolation.
SNG, CONT Continue to the next circular interpolation step continuously without stop.
REP, END Change the step number to the Repeat step number after the completion of the current step circular interpolation.
REP, KEEP Continue to the repeat step number after the completion of the current step’s circular interpolation.
REP, CONT The current circular interpolation and the repeat step number continuously without stop.

Additional Definitions

Parameter Definition
Target Position

Target Position is the position the step will be at when it is finished.

Operation Speed

Operation speed is the speed the axis will move at during the step.

Accel. No.

Choose the acceleration of the movement from the Axis Acceleration parameters.

Decel. No.

Choose the Deceleration of the movement from the Axis Deceleration parameters.

M Code Set the M Code when using the code number for sub operation of positioning control.
Dwell Time (ms) Dwell time is the time an axis waits after a movement for the axis to complete the step.
Sub. Axis Setting

Select the sub axis for an interpolation type movement. Set to none if not using interpolation.

Cr. Int. Auxiliary Point Set the secondary data (middle point, center point, radius) during circular interpolation. This is value used for the Cir. Int. mode selected.
Cir. int. mode

Set the generating method of arc (middle point, center point, and radius) during circular interpolation.

Circular int. turns Set the number of arcs to draw during circular interpolation. This can be used to perform circles over 360 degrees.
Helical int.

Set the axis to run linear operation during helical interpolation.

Multiple Position tables can be open at the same time to allow easy data manipulation across the selected axes.

Step Action
1

Open the Axis Position data tables that will be edited.
2

Open Window menu. Chose Tile Horizontally or Tile Vertically.
