Encoder failure causes and repair methods

　Absolute encoder this component, when we have been using it may be faulty problems, because even the most sophisticated instruments and equipment will have a failure. Binary encoder it can be expressed in two states, namely, on and off. This state can be realized by the height of the potential. Computers are made up of various electronic components. One of the important components is semiconductor i.e. familiar diodes, transistors etc. Semiconductors can transmit and process information through its switching state. If other systems are used, it will make the computer more complicated to manufacture and process information. So any information entered into the computer must eventually be converted to binary. At present, the common is ASCII code. The most basic unit is a bit. absolute value encoder wholesale from the single-turn absolute value encoder to multi-turn absolute value encoder, absolute value rotary single-turn absolute value encoder, in order to rotate the measurement of photoelectric code disk each channel engraved line, in order to obtain a unique code, when rotating more than 360 degrees, the code is back to the origin, so that does not comply with the principle of the only absolute code, such a code can only be used for the range of rotation of 360 degrees Such a code can only be used for the measurement within 360 degrees of rotation and is called a single-turn absolute encoder.

　　Binary encoders are subject to the following failures: noisy rotation, internal pin disconnection, wear of the resistor body (a basic type of component failure), burnout, and switch damage. The following is an analysis of the causes of these failures and how to deal with them.

　　Binary encoder rotation noise causes and treatment methods

　　Binary encoder appears to rotate the main reason for the noise is the resistance body wear (a basic type of component failure), so that the moving piece contacts and the resistance body between the contact is poor (line loosening), the resistance value is suddenly large and small, thus generating ;kala, kala ;the sound. At this time, you can use a multimeter (purpose: to measure voltage, current and resistance) according to the aforementioned method of detection, and then you will find the meaning: the clock used to indicate the corresponding time of the parts have jumped phenomenon.

　　For binary encoder with this fault, you can first use the cleaning method of troubleshooting, that is, using tweezers on the cotton ball dipped in anhydrous alcohol (termed ethanol), and then use the cotton ball near the rotor shaft, so that the alcohol is injected into the resistor body along the rotor shaft, and constantly rotate the rotor shaft until the noise disappears.

　　Binary encoder pin internal break causes and processing methods

　　When a binary encoder pin is internally disconnected, a binary encoder does not work, i.e., there is no change in the current or voltage of the circuit when the spindle is rotated. A tie-bit encoder is a device that converts a signal or data compilation into a form usable for communication, transmission, and storage by converting an angular displacement or linear displacement into an electrical signal, the former known as a code disk and the latter known as a code scale. Encoder signal outputs include sine wave, square wave, open collector, push-pull, and many other forms. For the volume binary encoder, there may be no sound fault, or volume off the phenomenon, when the multimeter (use: measuring voltage, current and resistance) detection (check and test) between the two fixed pins or fixed pins and sliding contacts between the pins of resistance, the resistance value of infinity or close to infinity, it can be judged that its pins of the internal broken circuit.

　　Carbon film resistor bodies can also burn out severely due to overcurrent and cause open circuits. Binary encoders that are open-circuited due to an internal break in the pin or a burnt-out resistor body are generally inconvenient to repair and are replaced.
