Hello we have a chevalier 1620 with fanuc drives and motors oimd control. Power is 208 3 phase. We have a problem with when the drives turn on we get 30 amps on each leg from the power coming in. Sometimes it will go away. Majority of the time we get 30 amp draw with nothing running. What ends up happening is it will trip the breaker when the breaker gets hot. We have been in contact with fanuc for over 30 days and chevalier. No one can figure this problem out. Does anyone have a idea of what would draw 30 amps when the machine isnt even running?
