The launch of the rotary P+F Pepperl+Fuchs encoder series, with its high-performance product characteristics, provides a more flexible and effective solution for global motor testing. Rotate a single-turn absolute encoder to measure each engraved line of the photoelectric code disk during rotation to obtain a unique code. When the rotation exceeds 360 degrees, the code returns to the original point, which does not comply with the principle of absolute code uniqueness. The encoding can only be used for measurement within 360 degrees of rotation, which is called a single-turn absolute encoder. If you want to measure rotation beyond 360 degrees, you must use a multi-turn absolute encoder.

On the basis of the single-turn encoding, the number of turns encoding is added to expand the measuring range of the encoder. Such an absolute P+F Pepperl+Fuchs encoder is called a multi-turn absolute encoder, which is also determined by the mechanical position. Each position code is unique and does not repeat, without the need to remember. Another advantage of multi-turn encoders is that due to the large measurement range, the actual use tends to be richer, so there is no need to laboriously find the change point during installation. It is enough to use a certain intermediate position as the starting point, which greatly simplifies the difficulty of installation and debugging. The pulses sent by the rotary encoder are counted, and then the coefficients of the mechanical transformation ratio and the radius of rotation are fixed, and the linear correspondence between the pulses and the actual travel distance can be obtained. PLC uses the high-speed counting module QD62D to read the value of the rotary encoder and perform digital processing, which can convert the pulse value into an actual distance value such as mm. At present, our equipment uses the original value of the rotary encoder for processing. The distance values on all touch screens are pulse values rather than actual distance values, which is more convenient and intuitive when processing data.
