Circular Interpolation

Circular interpolation is used to move two axes in a circular path based on the target position and type of circular interpolation mode.

  • The XPM_IST function block is used to execute the circular interpolation from the Position data table.

  • The axes being controlled must already be configured using the XG-PM software before using XPM_IST.

REQ Input Edge detected request to execute the function block
BASE Input Base number of the motion controller.Equal to 0 for built-in position control.
SLOT Input Slot number of the motion controller.Equal to 1 for built-in position control
AXIS Input Axis number of the main axis for the circular interpolation move.Set to 1 thru 6 for built-in axes. This can be a constant or variable.
STEP Input Step to execute in the position table.Must be a value between 0 – 400.If value is set to 0, then the current step is executed.This can be a constant or variable.
