introduction：Photoelectric encoder，It is a kind of sensor that converts the mechanical geometric displacement on the output shaft into a pulse or a digital quantity by photoelectric conversion。Photoelectric encoder output per revolution600（We use the boss didnt say）Pulse per unit，Five-wire system。Two of them are power cables，Three are pulse lines(Aphase、Bphase、Z)。The working voltage of the power supply is（ 5～ 24V）Dc power supply。The photoelectric encoder is composed of grating disk and photoelectric detection device。The grating disk is a certain diameter of the circular plate on the opening of a number of equal rectangular holes。Because the optical code disc is coaxial with the motor，Motor rotation time，The grating disk rotates at the same speed as the motor，Luminescence by meridian
