Hunan Code Disc Manufacturer: How to Judge Common Faults of Encoder

In many cases, the encoder is not bad, but only the main cause of intrusion, resulting in waveform is not very good, resulting in counting prohibition. Please tell me how to distinguish?

The encoder is a meticulous component, which is mainly due to the serious intrusion around the encoder, such as whether there is a large motor, DC welding machine continuously starting to cause intrusion, whether it is transmitted in the same pipeline as the power line, etc.

It is also very important to choose which kind of export opposite intrusion. Generally, it is better to export the power with opposite direction signals to resist intrusion, I .e. A ~ A- ,B ~ B- ,Z ~ Z-, which is characterized by the addition of 8-wire switching power supply instead of 5-wire (total zero). The transmission of power with reverse direction signal in the cable is symmetrical and less intrusive, and discrimination can be added to the receiving equipment (for example, when the receiving machine equipment signal uses the 90 phase angle of A and B data signals, and when the pulse signals 10, 11, 01 and 00 are seen, it is counted as an effective single pulse, and this method can effectively improve the anti-intrusion characteristics of the system).

Even encoders have their own advantages and disadvantages. There is a big difference in the data signal output of the internal power supply circuit of the code disc electronic device chip. Otherwise, how can a 1000 line incremental encoder be so different from more than 300 blocks to 3000 diversification?

① Clean (move out, turn off and protect) the source of intrusion, ② identify whether it belongs to the total error or leakage of the mechanical equipment gap, ③ identify whether it belongs to the control system and the power circuit socket of the encoder is inconsistent (the encoder model is not selected correctly);① ② ③ After the test, the problem condition can be basically identified. If it cannot be cleaned, it must be further analyzed.

What is the simple way to distinguish whether it belongs to the fault of the encoder itself. Now your enterprise encoder has been large-scale production, professional skills production has been perfect application, commodity problem rate can be in a few thousandths. The specific method of cleaning is to replace it with an encoder of the same type. If the problem is the same, cleaning at all is a difficult problem for the encoder, because the accidental occurrence of some problems with the two encoders at the same time may not be large and can be regarded as 0. If an encoder of the same type is replaced and the problem is cleaned immediately, it can be judged to be an encoder problem at all.

Hunan code disc manufacturer: the difference between encoder and code disc

In general, the encoder and the code wheel all refer to the encoder. But the detailed code disc is the grating ruler disc of the optical encoder.

Encoder: A machine device that writes and converts data signals or information into a method that can be used to communicate, transmit, and store signals.

The encoder converts the angular velocity or vertical offset into an electronic signal. The former is called a code wheel, and the latter is called a code ruler.
