Pulse distributor of stepping motor the pulse distributor of stepping motor can be realized by hardware or software method.
Hardware ring Distributor: composed of digital circuits such as counters.
It has good response speed, intuitive and convenient maintenance.
Software loop: composed of computer interface circuit and corresponding software.
Limited by the computing speed of microcomputers, it is sometimes difficult to meet the requirements of high-speed real-time control. Hardware ring distributor 2.
The method of software ring distribution software ring distribution is to use computer programs to set the bit State of the hardware interface, thus generating a certain Pulse Distribution output. 1)
The output interface corresponds the output of the computer to each phase winding of the stepping motor one by one.
8031 single chip microcomputer itself contains 4 8-bit I/O ports, P0, P1, P2 and P3.
To realize the Pulse Distribution of the three-phase stepping motor, three output port lines are required. In this example, P1. 0, P1. 1, P1. 2 bits are used as the output of Pulse Distribution.
