I am working with a EA1400n manipulator and a RM2-750TX positoner. This is using the NX100 controller. I need to know the proper way to calibrate the Robot to postioner calibration. I have been told two different ways to do it by two different Yaskawa techs and I need to know the correct way to do it that will give me the most accurate results. The TCP has been calibrated properly.
ROBOT to table Calibration

The way I have always done it -
Will this method be applied to a Ferris wheel type of positoner? We do not have a turntable on either of our Robots. The one I need to calibrate has a Ferris wheel. I have attached a couple photos of what it looks like.

I use the same procedure for all... the headstock plate is the same as a table top...

Ok that makes sense. However I now have the dilemma of our Robot arm does not reach the head stock on the positioner as it is a EA1400N, It is too short to reach all the way to the headstock.

OK in that case you might have to place a pointer on the beam. and teach it perpendicular to the center line.
But you must keep the posture of the robot the same. you will have to move rx, ry, and or rz.
if you can teach as shown you only have to move X, Y, and Z -
Ok so if I am doing it on the beam, should all of my points still try to be as close to the headstock as possible? or should I spread them apart as far as I can?

looks like your frame has some holes on the perimeter. I would install a sharpened bolt, and use that as your teach points
