Re: [CAD_CAM_EDM_DRO] Re: Hi frequency inverters and spindles

the only bad thing that could happen is if the motor
were to demand more current than it is designed for
(say in a stall condition), the 10 HP drive would
supply it whereas a 7.5 Hp drive would fault out. So
you could potentially burn up your motor. Other than
that......have at it.
