Hello, We have a LU35 4 axis lathe and our upper turret is stuck on the X limit switch and i can't figure out how to get it to move. I cannot find the Over Travel Release button. it has a OSP300 control. it doesn't apear to be in the electrical cabinet and i can't loacate it in the control.
Look for the over travel release switch on the top of the MF-EC1 board. Turn that to "I", then press NC reset to bring the servos back on - only pulse handle should be operational at this point. Move in direction to come off the switch, then turn the over travel release switch back off. BTW, you should never hit the overtravel switch - the stroke limits should stop you before that happens; you need to check those.
