Milwaukee, Wis.— AF91 microdrive may be one of the smallest ad-justable-frequency drives (AFDs) made. AF91 is geared toward customers who require AFDs for low-horsepower functions. Changing load conditions are monitored and controlled by ramp regulators. An automatic recovery mechanism will attempt to regulate a faulty condition up to nine times following the first indication something is wrong. A diagnostic fault indication feature will remember what caused the unit to shut down, alert the user, and diagnose a solution to prevent future occurrences. Cutler-Hammer
