Can damage be done to the machine by shutting down the phase converter? I have a service bulletin from Bridgeport that states that warranties are voided if a machine is run on a phase converter. I guess they have had bad experiences with phase converters or had no faith in them. Most create an artificial phase that varies greatly. I do not know if your phase converter can provide enough power to the drives. These controls can be fitted to many different size machines. The parameters are set such that the control knows how to accel, decel, rapid, etc the motors. Is your parameter sheet is wrong, or you are using a phase converter, the ability to accel a given amount of mass may not be there thus giving an error.
Try writing a simple program with no tool change and only one slow feed rate, say the X axis for one inch. You will need to turn the spindle on to do a feedrate. Repeat using a faster feed rate until it faults out. This will prove a point that the machine can move. It will also tell you at what speed it will fault out. You may have to change the parameters for rapid.

George, been running this machine on this phase converter for over a year now and no problems and the guy that owned it before used it with success.
