I had the same thing on mine with a Siemens control and I can't remember what it was exactly, but I think it was that I had a button pushed that I should not have had or there was a low lube warning on or something. Check everything like that.

Low way lube will create this problem. Also if the machine just thinks the way lube is low it will go into single block mode. I had to take my lube manifold that is behind the cover on the spindle end of the machine and take it apart to clean. After putting it back together, it was hell priming the lube system. I had to keep turning the machine off and then turning it back on so the initial startup pulses built enough pressure in the system to satisfy the alarm condition. Hope this helps.
