At least I belive there is no risk of damage to the motor! Somebody else may be able to confirm this for you keith. Overspeed could be an issue for the pump also!

Ok just checking! Even though the vfd input is 400volts the rated motor voltage should be set to 380volts within the vfd. Also the rated frequecy of the motor 50hz is at 380 volts the vfd can change this ratio and run the motor above 50 hz without damage there just becomes a point...
