Kia KT15 wont run program

I have kia kt 15 with yasnac lx3 was running a part when machine just shut down. restarted it every thing started back up servo turned on turret moves. when I push cycle start nothing happens tried to run in mdi didn't work . the alarm light is on on the control pad put there is no alarm or error code displayed. It shut off right when the spindle speed was going to reduce from 1500 to 800rpms.Any thoughts would be appreciated.


Thanks
