Information

DC Control Board refers to a master device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit according to a predetermined sequence to control the start, speed, brake and reverse of the motor.

DC Control Board

The DC Control Board is composed of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire system.

The DC Control Board is divided into a combination logic controller and a microprogram controller. Both controllers have their strengths and weaknesses. The combinatorial logic controller is cumbersome to design and has a complicated structure. Once the design is completed, it cannot be modified or expanded, but it is fast.

The DC Control Board is easy to design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, you only need to reprogram the corresponding microprogram; to add a machine instruction, you only need to add a microprogram to the DC Control Board. However, it is done by executing a micro process.
