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