1. Grating pollution This will reduce the signal output amplitude, and the oil must be quietly wiped off with absorbent cotton dipped in anhydrous alcohol.

2. Encoder connection cable fault: the probability of this fault is high, and it is often encountered in repair, which should be the 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 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.

4. Encoder battery voltage drop: this fault generally has a meaningful and clear alarm, at this time the battery needs to be replaced, if the reference point azimuth recall is lost, it is necessary to perform the operation of returning to the reference point.

5. 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 too low or the power transmission cable resistance is too large and causes loss, so it is necessary to overhaul the power supply or replace the cable.

6. Loose encoder device: This problem will affect the accuracy of azimuth control, form an out-of-tolerance in the azimuth error of stopping and moving, and even overload alarm of the servo system will occur as soon as the machine is turned on, please pay special attention.

7. 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.
