Installation And Use Of Pull Box Encoder

   An encoder (encoder) is a device that compiles a signal (such as a bit stream) or data into a signal form that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into an electrical signal, which is called a code plate, which is called a yardstick. According to the readout Mode encoder can be divided into two types: contact and non-contact; According to working principle, the encoder can be divided into two types: incremental and absolute. The incremental encoder is to convert the displacement into a periodic electrical signal, then turn the electrical signal into a counting pulse, using the number of pulses to indicate the size of the displacement. Each position of an absolute encoder corresponds to a determined number, so its value is only related to the starting and ending position of the measurement, regardless of the intermediate process of measurement.Pull Box Encoder
   Installation and use: Absolute rotary encoder Mechanical installation use: The absolute Rotary encoder mechanical installation has high-speed end-installation, low speed end of installation, auxiliary machinery installation and other forms. High-speed End installation: installed in the Power motor shaft end (or gear connection), the advantage of this method is high resolution, because the multiple-loop encoder has 4096 laps, the number of motor rotation circle in this range, can fully use the full range and improve the resolution, the disadvantage is that moving objects through the deceleration gear, to return the gear gap error, generally used in one-way high-precision control positioning, such as rolling seam control. In addition, the encoder is installed directly at the high-speed end, the motor jitter should be small, or it is easy to damage the encoder. Low-speed End installation: installed in the gear reducer, such as winch wire rope reel shaft End or the last section of the Reducer gear shaft end, this method has no gear to return to the gap, measurement more direct, high precision, this method generally measured long-distance positioning, such as a variety of lifting equipment, feeding car positioning and so on. Auxiliary mechanical Installation: Commonly used are gear rack, chain belt, friction wheel, collecting rope machinery.Pull Box Encoder
   The encoder has 5 leads, of which 3 are pulse output lines, 1 are COM ends, and 1 are power cords (OC Gate output type). The encoder power supply can be external power supply, also can directly use PLC $literal power supply. The power supply "-" end is connected with the encoder's COM end, "+" with the encoder's power side. The COM end of the encoder is connected with the PLC input COM end, A, B, z two-phase pulse output line directly with the PLC input end connection, a, b for the difference of 90 degrees of pulse, Z believe that the encoder in the rotation of a circle only a pulse, is usually used to do 0 points of the basis, the connection should pay attention to the PLC input response time. Rotary Encoder also has a shielding line, the use of shielding line grounding, improve anti-jamming.Pull Box Encoder
