P+F encoders are devices that encode signals (such as bitstreams) or data, converting them into a signal form that can be used for communication, transmission, and storage. Encoders convert angular or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to the working principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into periodic electrical signals, and then convert these electrical signals into counting pulses, using the number of pulses to represent the magnitude of the displacement. Each position of an absolute encoder corresponds to a specific digital code; therefore, its reading depends only on the starting and ending positions of the measurement, and is independent of the intermediate process.

P+F encoders can be classified as follows:

1. Classification by encoder die engraving method:

(1) Incremental type: A pulse signal is emitted for each unit angle rotated (some emit sine and cosine signals, which are then subdivided and chopped to produce higher frequency pulses). Typically, there are A-phase, B-phase, and Z-phase outputs. A-phase and B-phase outputs are pulses delayed by 1/4 cycle. The delay relationship distinguishes between forward and reverse rotation, and the rising and falling edges of A-phase and B-phase can be used for 2x or 4x frequency multiplication. Z-phase is a single-turn pulse, emitting one pulse per revolution.

(2) Absolute value type: For each revolution, a binary value corresponding to each reference angle is emitted. Multiple positions can be recorded and measured using an external clocking device.

2. Classification by signal output type: Voltage output, open collector output, push-pull complementary output, and long-line drive output.

3. Classification by encoder mechanical mounting method:

(1) Shaft type: Shaft type can be further divided into clamping flange type, synchronous flange type, and servo mounting type, etc. (2) Bushing type: Bushing type can be further divided into semi-hollow type, fully hollow type, and large diameter type, etc.

4. Based on the working principle of the encoder, it can be divided into: photoelectric type, magnetoelectric type, and contact brush type.

P+F encoder installation and use

Mechanical installation and use of absolute rotary encoders:

The mechanical installation of absolute rotary encoders includes high-speed end installation, low-speed end installation,

auxiliary mechanical device installation, etc.

High-speed end installation: Installed on the shaft end of the power motor (or gear connection). The advantage of this method is high resolution. Since multi-turn encoders have 4096 turns, the number of motor rotations is within this range, which can fully utilize the range and improve resolution. The disadvantage is that after the moving object passes through the reduction gear, there is gear backlash error in the return stroke. It is generally used for unidirectional high-precision control and positioning, such as roll gap control in steel rolling. In addition, when the encoder is directly installed on the high-speed end, the motor vibration must be small, otherwise the encoder is easily damaged. Low-speed end installation: Installed after the reduction gear, such as at the shaft end of a hoisting wire rope drum or the shaft end of the last reduction gear. This method eliminates gear backlash, resulting in more direct and accurate measurements. It is generally used for long-distance positioning measurements, such as in various lifting equipment and material handling trolleys.

P+F encoder auxiliary mechanical installation:

Commonly used methods include gear and rack systems, chain belt systems, friction pulleys, and rope winding mechanisms.
