The ERO ELECTRONIC controller is a master command device that controls motor starting, speed regulation, braking, and reversing by changing the wiring of the main circuit or control circuit and altering resistance values in the circuit according to a predetermined sequence. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It serves as the "decision-making unit" for issuing commands, coordinating and directing the operations of the entire computer system.
