The switching function is adjustable between 0 and The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuators exact fail-safe position.

This SPDT switch is provided for safety interfacing or signaling, beelimo example, for fan start-up. The ASIC monitors and controls the brushless DC motors rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition.
