Positioner calibration is a function that enables the robot to perform a synchronized follow-up with the operation of a jig device installed outside the robot or to perform a linear or circular operation relative to the jig device. The external jig device in which the positioner calibration function will be applied to is called a positioner or station.
Using the positioner calibration function makes it possible to compensate for the operational difficulties because of the limitation of the robot operation area. In other words, even if the positioner moves while the workpiece is fixed onto it, the robot can still perform a linear or circular operation on the workpiece by following up with the movement of the positioner.
You can simply set the positioner’s coordinate system by performing the positioner calibration by teaching three points for a 1-axis positioner and five points for a 2-axis positioning.
