haas 160 alarm

[s00073055]

hello all, iam trying to run a 94 haas vfo off a 40kva 3 phase generator i checked the input voltage and getting 410v and have connected to the correct input terminals on the tranformer, when i power up i get the servos off alarm, and the low voltage 160 alarm. i bought the machine from a workshop and seen it working ,it was a 1 year 7 months before i put power to it. does anyone see what i have done wrong here or have any ideas thanks.

410 volts sounds a little out of range. Im thinking the voltage should be in the range of 440-480 volts. Is the voltage the same going into the phase converter? What is the voltage from each leg to ground? (277?)

thanks for reply. i have 235 from leg to ground its looking like this is to low, it said on the installation notes not to exceed 260volts so i want to be careful about that.

Sounds low to me also. Usually on 460 volt 3 phase its 277 volts to ground with a range of 260-285 volts from what I have personally seen. I would check the voltage at your main circuit panel also. The power company may not be sending you enough voltage through their transformer. Line to line should be within 440-480 volts. Good luck.
