It will depend on the controller used.

Most sets have at least-
Low oil pressure,
High engine temperature,
Low coolant level,
Over speed,
Under Speed,
Low AC volts,
High AC volts,
Over current,
Short circuit,
Weak battery,

Paralleling sets will also have-
Reverse power,
Loss of excitation,
Phase rotation,
Synch check,
Braeker fail to close,

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
