Without repetition, without the need for memorization. Another advantage of multi turn encoders is that due to their large measurement range, they often have more flexibility in practical use. This way, there is no need to struggle to find the zero point during installation, and a certain middle position can be used as the starting point, greatly simplifying the difficulty of installation and debugging. The advantage of multi turn absolute encoders in length positioning is obvious. Currently, most of the newly developed servo motors in Europe use multi turn absolute value encoders. 3. The sine cosine servo motor encoder consists of a photoelectric encoder with a central axis, on which there is a circular pass

Dark engraved lines, read by photoelectric emitting and receiving devices, obtain four sets of sine wave signals combined into A B、C、D, Each sine wave has a phase difference of 90 degrees (360 degrees relative to one cycle). By reversing the C and D signals and superimposing them on the A and B phases, stable signals can be enhanced; Additionally, output a Z-phase pulse for each revolution to represent the zero reference position. A regular sine cosine encoder has a pair of orthogonal sin, cos1Vp-p signals, which are equivalent to the AB orthogonal signals of an incremental encoder for square wave signals. Each cycle repeats many signal cycles, such as 2048; And a narrow symmetrical triangle
