D674A906U01 FET3251COP1B4COH2 Automatic spare parts

The controller D674A906U01 FET3251COP1B4COH2 is the master command device which controls the start, speed regulation, braking and reverse of the motor by changing the connection of the main circuit or control circuit and changing the resistance value in the circuit according to the predetermined sequence. D674A906U01 FET3251COP1B4COH2 is composed of program counter, instruction register, instruction decoder, time sequence generator and operation controller. It is the “decision mechanism” to issue commands, that is, to complete the coordination and command of the operation of the whole computer system.

Controller D674A906U01 FET3251COP1B4COH2 consists of a combination logic controller and a microprogram controller. The two controllers have their own advantages and disadvantages. Combinatorial logic controller is cumbersome in design and complex in structure. Once the design is complete, it cannot be modified or expanded, but it is fast. Microprogram controller is convenient in design, simple in structure, easy to modify or expand, modify the function of a machine instruction, only need to reprogram the corresponding microprogram; To add a machine instruction, just add a microprogram to the control memory, but it does so by executing a microprogram. The specific comparison is as follows: combinational logic controller, also known as hardwired controller, is composed of logic circuit, completely rely on hardware to achieve the function of instructions.
