Error wohlenberg 115. asix 7 not calibrated

If anyone can help me, thanks in advance. I have a 1996 Wohlenberg 115 guillotine that won't let me move the rear carriage. When I try to move it, I get the error "Axis 7 not calibrated." And if I try to calibrate it in operator mode, it still won't let me.

 

Did you try calibrating the knife? If you entered that screen without completing it, it wont let you calibrate the back gauge.

 

I haven't tried calibrating the blade yet. I'll try calibrating the blade to see what happens.
