Hey all.

My Mazak QT18 NSP opened up the other morning with the Spindle Stop key blinking red. It will not let me operate main chuck (sub chuck works), barfeeder or rpm on either spindle, nor will it let me run any programs. I can click the keys switching the rpm from CW to CCW, but I can not press the stop to make it stop blinking and there is also no reaction when I press start spindle.
It feels like some conditions has not been fullfilled, but I'm at a loss here. Been going through prcedures and ladder diagram and not finding anything

Any ideas?

Thanks!
