Hello!
I have cnc lathe Hyundai HIT-200M, it's on Sinumerik 840D.
I have to make turret reference, it's on Mitsubishi MRJ2S-100A servodriver, turret have absolute encoder so there's battery for hold on memory of zero position.
But battery was broken, and i have alarm at mitsubishi AL.90 which means "Home position return incomplete".
Anyone know maybe how to make reference of turret at this machine?Is there some procedure for it.

Thank you

You should contact SIEMENS, there is a procedure to realign the turret.
