摘要: A frequency control method is incorporated in a motor drive to prevent overcurrent trips when an induction subjected impact loads or reconnection under load. The includes current regulator loop stator and voltage the command regulator. Motor sensed error developed. This processed through proportional-integral which controls operating signal responds during limit conditions reduce speed until subside. can then be re-accelerated up desired speed.
