Bending machine encoder

The encoder of the bending machine consists of a photoelectric code disk with a shaft in the center, on which there are circular and dark engraved lines, and is read by photoelectric transmitting and receiving devices to obtain four groups of sine wave signals combined into A, B, C, D , Each sine wave has a phase difference of 90 degrees (relative to a cycle of 360 degrees), the C and D signals are reversed and superimposed on the A and B phases to enhance the stable signal; in addition, a Z-phase pulse is output per revolution To represent the zero reference position. Since the phases A and B are different by 90 degrees, the encoder's forward and reverse rotation can be judged by comparing whether the A phase is the first or the B phase. The zero reference position of the encoder can be obtained through the zero pulse.Bending machine encoder The materials of the encoder code disc of the bending machine are glass, metal, plastic. The glass code disc is a thin scribe line deposited on the glass, which has good thermal stability and high accuracy. The metal code disc is directly scribed with and without pass. Not fragile, but because metal has a certain thickness, the accuracy is limited, and its thermal stability is an order of magnitude worse than that of glass. The plastic code wheel is economical, and its cost is low, but the accuracy, thermal stability, and life are all It's worse.Bending machine encoder Resolution—The number of open or dark engraved lines provided by the encoder of the bending machine per 360 degrees of rotation is called resolution, also called resolution indexing, or directly called the number of lines, generally 5 to 10,000 lines per revolution.Bending machine encoder okplazas.com specializes in the production and sales of various bending machine encoders, can provide bending machine encoder selection, bending machine encoder quotation, bending machine encoder installation instructions, bending machine encoder maintenance and other services, welcome to consult !
