 From the proximity switches, photoelectric switches to the rotary encoders: Industrial control positioning, proximity switches, photoelectric switch application has been very mature and easy to use. 
 But as the continuous development of industrial control, has a new requirement, so that the application of rotary encoders used to highlight the advantages of: information technology: In addition to positioning, but also know the specific location of the control room 
 ; Flexibility: Flexible positioning can be adjusted in the control room; site installation convenience and safety, and longevity: the size of a fist, rotary encoders, can be measured from several μ to several hundred meters from the n-station, as long as the solution the safety of a rotary encoder installation problems, avoid a lot of proximity switches, photoelectric switches installed in the field machine trouble, crashed and was easy to heat, moisture problems and other issues. As is the photoelectric encoder, no mechanical wear and tear, as long as the installation location is accurate, its life is often very long. Multifunctional: in addition to positioning, but also remote current location, speed for conversion, 
 For the inverter, stepper motor applications such as particularly important.

 Economy: the control station for more than simply the cost of a rotary encoder, and more importantly, installation, maintenance, wear and tear costs 
 , Life growth of the economy gradually exposed. As mentioned above the advantages of rotary encoder has been more and more widely used in various industrial applications. 
 From the incremental encoder to the absolute encoder: rotary incremental encoder to turn the output pulse by counting the device to know its location, when the encoder is not fixed, or power failure, 
 Rely on counting device's internal memory to remember the location. Thus, when the power outage, the encoder can not have any movement, when the calls work, the encoder output pulse during 
 Can not interfere with the loss of pulse, or, counting equipment will offset the zero memory, and this is no way to know the amount of offset, only the wrong results to be known production. 
 The solution is to increase the reference point, after a reference point for each encoder, the reference position into the counting device modified memory location. In the reference point before the location can not guarantee the accuracy.

 To this end, each operation in the industrial in there first find the reference point, the boot give change and other methods. For example, the positioning of the scanner printer is to use the principle of incremental encoders, each boot, 
 We can hear the burst of Pilipala sound, it was looking for reference point, then work. This approach is too much trouble for some industrial projects, 
 Not even allowed to give change boot (boot will know the exact location), so there is the emergence of the absolute encoder. Absolute rotary encoder, absolute position of each unique because of its anti-interference 
 Without power-down memory, has been more widely used in various industrial systems point of view, length measurement and positioning control. Optical encoder absolute encoder, there are many road carved lines, 
 Engraved lines each in turn to 2 lines, 4 lines, 8 lines, 16 lines. . . . . . Arrangement, so that at each position encoder, by reading through each line of carved, dark, 
 Get a zero power from 2 to 2 n-1 power only 2 binary code (Gray code), which is called n-bit absolute encoder. This encoder is a mechanical encoder position from the decision, 
 It is not power, interference. Absolute encoder determined by the mechanical position of the uniqueness of each location, it does not need memory, need to find the reference point, and do not have count 
 When you need to know the location, when the position went to read it. Thus, anti-interference characteristics of the encoder, the reliability of data is greatly enhanced.

 Because of the absolute encoder is much better than in the positioning of the incremental encoder has been increasingly used in industrial positioning. Because of its high-precision absolute encoder, the output bits more 
 If still using a parallel output, each of its output signal to ensure a good connection, but also for more complex conditions isolation, the number of multi-core connection cables, thus causing much inconvenience and reduce the reliability of 
 Therefore, the absolute encoder output in a multi-digit type, generally use the serial output or bus-type output, the German production of the absolute encoder is the most common serial output SSI (synchronous serial output). 
 From single-ring absolute multi-turn absolute encoder to the encoder: rotary single-turn absolute encoder to measure the optical code disk rotating in the groove of the road in order to obtain a unique code, when the rotation over 360 degrees, 
 Code back to the origin, so as not to comply with the principle of absolute encoding only, so that the encoder can only be used to rotate 360 ??degrees within the range of measurement, known as single-ring absolute encoder. 
 If you want to measure the rotation over 360 degrees, it is necessary to use multi-turn absolute encoder. Encoder manufacturers use the principle of mechanical gear clocks, when the center of rotation encoder, 
 Through another set of gear code disc (or set of gear, multiple sets of code disk), encoded in a single lap on the basis of the code to increase the number of turns in order to expand the measuring range of the encoder, 
 This is called an absolute multi-turn encoder Absolute encoder, it is also determined by the mechanical position encoder, encoding the only non-repetition of each position, without memory.

 Another advantage of multi-turn encoder is due to measurement range, the actual use is often more affluent, so that unnecessary struggling to find zero installation will be an intermediate position as a starting point on it, 
 Greatly simplifies the installation and debugging difficult. Absolute multi-turn encoder positioning in the length of the obvious advantages, has been increasingly used in industrial positioning. 
 Absolute rotary encoder mechanical installation: absolute mechanical rotary encoder side installation to install high-speed, low-side installation, auxiliary machinery installations and other means.

 High-speed side installation: Installation in the power end of motor shaft (or gear connection), the advantages of this method is high resolution, the multi-turn encoder with 4096 laps, the motor rotation number within this range, 
 Foot range and can be fully used to improve the resolution, the disadvantage is, after moving objects through the reduction gear, to return a gear clearance error, generally used for one-way high-precision positioning control, such as rolling of the roll gap control. 
 Another high-speed encoder directly on the side of the motor to be smaller jitter, or easily damaged encoder. Low-side Installation: Install the reduction gear, the 
 Such as the winch rope drum shaft or the last one reduction gear shaft, this method is no longer to gear backlash, more direct measurement of high precision, this method is generally measured distance positioning 
 For example, a variety of lifting equipment, feed cart positioning. Auxiliary machinery installation: commonly used rack and pinion, chain belts, friction wheels, closing rope machinery.
