Encoder fault classification

⑴ Encoder malfunction: refers to the failure of the encoder's components, which prevents it from generating and outputting the correct waveform. In this case, it is necessary to replace the encoder or repair its internal components.

⑵ Encoder connection cable fault: The probability of this fault occurring is often encountered during maintenance and should be a priority factor to consider. Usually, it is due to open circuit, short circuit or poor contact of the encoder cable, in which case the cable or connector needs to be replaced. Special attention should also be paid to whether the loosening caused by loose cable fixation leads to welding or circuit breaking. In this case, the cable should be clamped tightly.

⑶ Encoder+5V power supply drop: refers to the situation where the+5V power supply is too low, usually not lower than 4.75V. The reason for the low voltage is due to power supply failure or excessive resistance of the power transmission cable, which causes losses. In this case, the power supply needs to be repaired or the cable needs to be replaced.

⑷ Encoder battery voltage drop: This fault usually has a clear alarm meaning, and the battery needs to be replaced. If the reference point position memory is lost, the operation of returning to the reference point must also be performed.

⑸ Encoder cable shielding wire not connected or detached: This will introduce interference signals, make the waveform unstable, and affect the accuracy of communication. It is necessary to ensure reliable welding and grounding of the shielding wire.

⑹ Loose installation of encoder: This fault can affect the accuracy of position control, causing excessive positional deviation during stopping and movement, and even generating servo system overload alarm as soon as the machine is turned on. Please pay special attention.

⑺ Grating contamination can cause a decrease in signal output amplitude, and the oil stains must be gently wiped off with a degreasing cotton.

Rotary encoders convert mechanical inputs into electrical signals, which can be processed by counters, tachometers, programmable logic controllers, and industrial PCs.

The force on the encoder shaft is the main cause of bearing damage. Bearings may be subjected to both radial and axial loads. The load of bearings usually comes from installation errors and rollers or transmission gears. When the radial and axial loads increase, the bearing life becomes shorter. Therefore, it is very important to reduce bearing load and installation errors during encoder installation.

The encoder shaft is connected to the measured shaft through a flexible coupling. The coupling compensates for the axial and radial misalignment (radial and angular misalignment) between the rotary encoder and the drive shaft. This ensures that the rotary encoder bearings are free from external forces and that external forces do not affect their service life. If the encoder shaft is subjected to high forces, such as in the application of friction wheels, pulleys, or sprockets, Okate Company recommends installing bearing components for buffering.

Intrusion refers to foreign objects entering the bearing. Bearings are precision components, and the entry of any foreign object will cause a sharp decrease in bearing life. precisely because

For this reason, many encoders use sealing mechanisms to prevent foreign objects from entering.

The mechanical lifespan of rotary encoding is mainly determined by bearings. The expected service life of bearings depends on shaft load, temperature, shaft speed, and other factors

Things.

The situations discussed earlier together determine the lifespan of the bearing. We can reduce the axial force caused by installation errors and adopt appropriate measures

When sealing to prevent foreign objects and avoid unnecessary high temperatures to improve bearing life.

1. What is an "industrial rotary encoder"

Industrial rotary encoder is a type of rotary angle encoder that pre encodes the angular position relationship and outputs measurement values

Sensor, when measuring, can read the current angle position value or the angle change of motion movement, through a mechanical transmission device

It is also possible to measure length and height values, and the change in displacement can be obtained by taking the derivative of time to obtain the velocity and acceleration of the motion

Sensors or command transmitters.

2. What is an incremental (counting) encoder (also known as a relative encoder)

Incremental encoder, with pre position encoding internally, but its specific position needs to be based on the position relationship of two readings (e.g

The accurate position can only be obtained by the measurement method of increasing or decreasing the count relative to zero point Z and storing it electronically

Because the encoder determines its position based on two reading relationships, it is also called a "relative" encoder. The encoder has a dependency inside

All encoders that rely on the storage and accumulation of previous readings are relative encoders.

For example, the internal encoder of the following photoelectric incremental encoder: the number of engraved lines represents the A.B phase encoding for each interval position, with each revolution

A engraved line is the zero position Z phase, and the specific position is determined by the number of engraved lines relative to the Z phase or the relative movement of each line

Determine the relative movement from the starting point of the previous reading to the end point of this reading at what angle position.

Optical incremental encoder code disc form

3. What does it mean

It refers to the position value of the measurement origin that does not depend on the accumulated count of the previous measurement.

It is different from "relative value", which refers to the position value of a relative movement relative to the previous measurement position

Each normal measurement is unrelated to any other measurement relationship, so it is called.

4. What is encoding

Encoding refers to the pre positioning of all mechanical positions within the measurement range inside the measuring device (sensor)

The code that corresponds to the origin of the mechanical position, so that measurements at any time do not need to rely on the history of the previous measurement

History. Encoding that can be directly output even without moving.

The fundamental principle of encoding is to obtain complete location information without relying on movement, and each location is,

The second is unrelated to the previous reading (including various memory methods). Do not move the position, do not need to know the previous reading position

Measure and output the signal value.

What is the difference in "encoding"

The fundamental difference is that the name "formula" focuses on measuring the position of the receiving device relative to the external origin

Set the output mode, while "encoding" focuses on measuring the internal encoding form of the sensor, and within its range

Encode all positions at the origin position. As an encoder, it should be determined based on the principle of internal encoding reading

Determine its naming convention.

Actually, it relies on counting, whether it's internal battery memory, external batteries, or even low-power Wiegand meters

Numbers, all of which are 'counting', can no longer be called 'encoding' and can only be relative to the measurement receiving equipment“
