Abstract: An intelligent automatic bypass for a motor control device determines if a fault that is occurring in the motor control device is a restricted or non-restricted fault. A restricted fault is one that may damage or destroy the motor if an automatic switch to bypass is allowed to occur for all faults that occur in the motor control device. The intelligent automatic bypass allows the automatic switch to bypass only if the fault is a non-restricted fault and blocks the automatic switch to bypass if the fault is a restricted fault.
