VDF Spindle encoder failure

Round Head

Jun 23, 2015
I am running a VDF180CTe 2 axis turning center. Siemens 840D My spindle encoder has died and we are weeks out getting a new one.I would like to run my programs for some simple turning with no threading and no tapping. I can program using G94 mm/min instead of G95 mm/rev everything works except when starting the spindle the spindle feedback to the control is not there so the machine will not move after I start the spindle in the program My spindle starts fine and runs fine..just says 2 rpm on control vs 1000 rpm programmed. My question...Is there a parameter that I can turn off to bypass the spindle feedback to the control.
