Abstract
A system and computer-implemented method for improving controlling the operation of an alternating current electric motor using programmable multiplexed tap input logic. Programmed bit patterns and corresponding tap numbers are stored in a look-up table in a non-volatile electronic read-write memory element. Input channels are monitored for tap input signals, and an input bit pattern is formed based on the tap input signals. The input bit pattern is compared to the programmed bit patterns, and if the input bit pattern matches a particular programmed bit pattern, then a control signal is transmitted to activate the particular tap number which corresponds to the particular programmed bit pattern, thereby controlling the operation of the motor. If there is no active tap, then the motor is turned off. The programmed bit patterns and/or the corresponding tap numbers may be changed by writing to the look-up table in the non-volatile electronic read-write memory element.
