An encoder is a device that compiles or converts signals or data into signals that can be communicated, transmitted, and stored. The encoder converts angular or linear displacement into an electrical signal.
Fault Symptom:
1. Encoder own fault: It refers to the failure of the encoder's own components, resulting in its failure to generate and output correct waveforms. In this case, the encoder needs to be replaced or its internal components repaired.
2. Encoder connection cable fault: this fault has the highest probability of presenting, and it is often encountered in repair, so it should be a priority factor. Generally, the encoder cable is open, short-circuited, or in poor contact, and the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is not tightly fixed, forming loose and causing open welding or breaking, at which time the cable needs to be clamped.
3. Encoder +5V power supply decline: It means that the +5V power supply is too low, generally not lower than 4.75V, and the reason for the formation is that the power supply is faulty or the power transmission cable resistance is too large and causes loss, so the power supply needs to be repaired or the cable replaced.
4. Affirmative encoder battery voltage drop: this kind of problem generally has a meaningful and clear alarm, at this time the battery needs to be replaced, if the reference point position is lost, it must also be performed back to the reference point operation.
5. The encoder cable shield wire is not connected or falls off: this will introduce a disturbing signal, make the waveform unstable, and affect the accuracy of communication, so it is necessary to ensure that the shield wire is reliably welded and grounded.
6. Loose encoder device: This problem will affect the accuracy of position control, form a position error in abort and movement, and even the servo system overload alarm occurs as soon as the machine is turned on, please pay special attention.
Precautions for selection:
1. Mechanical device scale: including positioning stop, shaft diameter, device hole position; cable outlet method; the volume of the installation space; Whether the protection level of the working environment meets the requirements.
2. Resolution: that is, the number of pulses output per turn when the encoder is working, and whether it meets the requirements of planning and application accuracy.
3. Electrical interface: encoder output methods commonly include push-pull output (F-type HTL pattern), voltage output (E), open collector circuit (C, common C is NPN tube output, C2 is PNP tube output), and long-line driver output. The output method should match the interface circuit of the control system.
