Problems with centrifugal fans, experts please help

New centrifugal fan, 355kw rated current 690A. Previously it was done manually, and the program was tested separately; operating at 50HZ gave normal results with normal current levels ； Currently, it can only operate at 80%; at 38HZ, the current is already over 660A. There were no issues with the current during previous testing – could someone experienced give some advice?
