摘要: Methods an apparatus are presented for identifying ground fault locations in multi-drive systems which individual drives perform self-diagnosis detected faults based on identified signal frequency while the system continue operation, and a location identifies suspected individually confirms or exonerates by selective command speed adjustment remain operational within tolerance ranges.
