Abstract:
A method and controller to automatically determine a grounding condition of a motor drive, in which an inverter is operated at a predetermined frequency while a load resistor is connected between a single phase of a motor drive inverter output and a reference node, a leakage flux linkage value is computed according to a neutral-ground voltage of the motor drive, and a processor determines whether the motor drive is solid grounded, high-resistance grounded, or floating according to the leakage flux linkage value. In certain examples, the processor automatically turns the inverter off while the load resistor is connected between the single phase of the inverter output and the reference node, and automatically determines whether the motor drive is delta corner grounded according to the neutral-ground voltage.

Claim (Index 9):
The motor drive of  claim 8 , wherein the processor is further configured to execute the program instructions to automatically determine that the motor drive is high-resistance grounded if the leakage flux linkage value is greater than or equal to the first threshold value and the leakage flux linkage value is less than or equal to the second threshold value.
