Custom angle encoders encoder 

 In practice, the faults caused by rotary encoder are not a few, and it is quite troublesome to check. Sometimes, although it has been checked, it is still not reassuring. Therefore, I would like to introduce a simple method to confirm the rotary coding fault. From the schematic diagram of the drive and regulation system, it can be clearly seen that it is because of the rotary coding that the microcomputer inverter motor is between. If there is a problem with the rotary encoder, the abnormal feedback signal will inevitably affect the normal operation of the motor. At this time, we simply turn the feedback of the rotary encoder off to open-loop control, If the motor can still be in normal fast running state, then it can be determined that the elevator fault is really generated on the rotary encoder, otherwise it should be found in other aspects. This is the theory and method to confirm the fault of rotary encoder. Application Precision measuring…
