Pepperl+Fuchs decrypts it for you why the encoder suddenly strikes at work

Pepperl+Fuchs customer service recently encountered a problem from a customer, saying that the encoder in use often has no data, and the value is fixed at a value without changing, and it resumes counting after a period of time. I tried to replace the template and cable, and the 24V power supply was normal when a problem occurred. The problem still exists. The situation like this is basically caused by the following reasons.

When the encoder has such a problem, you can also consider whether there is an error or the magnetic field environment is too strong at the beginning of the setting. In fact, the basic reasons for the encoder failure can be roughly divided into four categories: 1. The encoder cannot correctly feedback the actual speed due to installation reasons; 2. The encoder component is damaged; 3. There is a problem with the encoder circuit; 4. The environmental magnetic field factor . Since the encoder encoder is installed differently, the result is that the speed is fast and slow. The consequence is that the motor oscillates and decelerates. The external phenomenon is the sound of the motor as if the bearing is broken. (This is a DC used on a straightening machine. Motor, 185KW). I only encountered this phenomenon recently. I discovered it from the comparison of the speed and current curves. When I processed it, I didn't notice what caused it. I analyzed it afterwards. Combining the Qujing Come to this conclusion.
