Can a magnetic induction encoder replace an L B encoder? Does it have anything to do with the system

What PLC are you using? The high-speed port of each PLC is different, in addition, whether you use an external module or use a unit PLC, its connection is different, if you use the built-in high-speed port, the connection method is relatively simple, A phase is connected to X0, B phase is connected to X1, Z phase can not be connected, because Z phase is a weekly pulse phase, that is, the encoder rotates one week for a pulse, according to your needs, if you want to use, you can connect to any input port. Shanghai Barutu Construction Machinery Technology Co., Ltd. will answer for you.

Guboa, this magnetic induction encoder, I have a guest to replace the L+B encoder, but there are many types of L+B encoders, and if you want to replace the parameters of the system without changing them, use them normally as before, then you need to meet the following points:

1. You need to find out the original parameter requirements of the motor, understand whether it is a square wave output or a sine wave output, and compare the waveform;

2. Measure the size of the original encoder, and consider whether to choose the standard type or micro type of GUBOA magnetic induction encoder in combination with the size of the original encoder and the installation space;

3. Confirm whether the voltage of the encoder is 5V and the electrical interface;

4. Confirm whether the driver of the encoder and the encoder can be used universally, including the speed accuracy requirements, etc., which is generally no problem.

The above is the general problem that needs to be considered to replace the L+B encoder with the GUBOA magnetic induction encoder, and the replacement of other encoders is also similar. I hope it can help you, if you have any other questions, you can always ask or send me a private message, Suzhou Bodi Electromechanical Adong is happy to learn and progress with you.

Germany VS Sensorik spindle encoder can better replace L+B encoder, you can send me a private message for details.

The magnetic induction encoder is a magnet-based non-contact sensor designed as a magnetic induction sensor to sense the number of teeth on the gear. It is a non-contact magnetoelectric encoder that processes the circuit to fix the tremor or split signal into 1VPP or TTL (RS422LINE Driver) signals.

The selection of magnetic induction encoder mainly involves the specifications and characteristics of the electrical appliances themselves, and the use of the environment on the other hand. According to the specifications and characteristics of electrical appliances, the magnetic induction encoder is selected according to the specifications and characteristics of its own electrical appliances, and the selection of the magnetic induction encoder mainly needs to consider the use of collapse and vertical, the collocation with the system, the selection of absolute and incremental commands of the encoder, the selection of the resolution of the magnetic induction encoder, the selection of sine wave and square wave, etc.

In addition to the information provided above, the selection of magnetic induction encoder should also consider the cost budget of the customer. Well-known foreign brands such as Siemens, Fanuc, Tamagawa, etc., and brands such as Guboa are slightly more cost-effective, and the parameters are interchangeable.

The selection technology level of magnetic induction encoder is the interface of the joint section, the output signal of the encoder, the parameters, and the specifications of the matching gears, etc., in addition, the characteristics of some customers also need to consider the wire length of the noisy encoder, etc., followed by the brand of the encoder, the brand of the magnetic induction encoder is still quite a lot, most of the previous Fanuc, Siemens, Tamagawa Heidenhain, and now the market share of the Guboa encoder has also increased, which is roughly to consider these aspects.

IC-HAUS China - Magnetic encoder chip in the MU series, the incremental encoder is a pair of magnetic poles of one turn (column), absolutely 2 turns (2 rows or 3 rows) of magnetic pole pairs, through the nonius principle of vernier calipers to achieve absolute measurement of singleturn position. Multiturn is the weft root effect, which powers the memory and remembers the position.

How the encoder works, how it works is analyzed.

The working principle of encoders and the differences between four-wire and five-wire encoders.

Different encoders work in slightly different ways, but in general, an encoder is a component that converts a mechanical signal with a change in displacement into a digital signal.

Rotary encoders, two types. One is how many pulses are emitted in one revolution. The faster the pulse, the more pulses.

One is how much speed and how much voltage is generated. The faster the voltage, the higher the voltage.

I guess you're talking about the second option.

What type of encoder DU is the landlord Bai is talking about, if it is an electric spindle coder, I can talk about my internal opinion.

At present, the electric main capacitor shaft encoder mainly relies on imports, mainly for the three major German brands: Heidenhain, L+B, VS. Let's talk about the pros and cons of a few brands::

1. Heidenhain: Heidenhain is recognized as the world's highest precision encoder, mainly producing magnetic grid encoders, although the accuracy is high, but its cost is too high, and the magnetic ring is susceptible to magnetic interference, and the current electric spindle is basically using magnetic induction incremental gear encoder to replace magnetic grid encoders.

2. L+B: It entered the Chinese market earlier, has high recognition and complete models, but the grease coating layer on the surface of its readhead is easy to scratch, which affects the reading of the signal, and the interference with strong magnetism is not very strong.

3. VS:VS is the encoder of major spindle manufacturers in Europe, its magnetic induction incremental gear encoder can be fully compatible with the replacement of L+B encoders, and its readhead is not greased, and the design of fully enclosed metal shell is adopted, its anti-magnetic interference can reach 30kV, which can be used in strong magnetic environments such as synchronous motors.

The working principle of the four-wheel battery car loan code device.

Zhongshan Baidi Electromechanical Dong Gong is happy to help you with this question, there are several ways to judge whether the magnetic induction encoder is burned out. Generally, customers will use a universal meter to measure, and the perpetual chronometer can measure whether it is broken, but the waveform cannot be seen. If the oscilloscope is measured, it is more intuitive, you can see the waveform of the encoder, A+, A-, B+, B-, Z+, Z-, these groups of signals, and then which group of signals are abnormal, the waveform can be displayed.

For example, the qualified current of our GUBOA encoder is 18-25mA, and the qualified voltage is 5V 10%; Forward rotation qualified waveform a b z phase; Invert the phases of the qualified waveforms a, b, and z. When the current is 25mA and the voltage is 5V, there is no problem with the power supply. During the forward rotation test, there is no voltage in the output of A, B, and Z signals, and the power supply is judged to be burned.

It mainly depends on whether the signal can be sent, and whether the signal misses, if there is, it may be broken.

Touching its forehead, it is hot and it is burned.

Is there an encoder**? Send me to see if it can be replaced.

They cannot be substituted for each other, and the differences between the two are as follows:

First, the reference is different.

1. Incremental encoder: It converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses indicates the size of the displacement.

2. Absolute value encoder: each position corresponds to a certain digital code, so the indication value is only related to the start and end positions of the measurement, and has nothing to do with the intermediate process of measurement.

Second, the characteristics are different.

1. Incremental encoder: when the rotating shaft rotates, there is a corresponding pulse output, and the judgment of the direction of rotation and the increase or decrease of the number of pulses are realized with the help of the direction circuit and counter at the rear. The starting point of the count can be set arbitrarily, which can realize the infinite accumulation and measurement of multiple turns.

Third, the principle is different.

1. Incremental encoder: when the code disc rotates with the working shaft, the light and shade change will be generated every time it turns through a gap, and then after shaping and amplification, the electrical pulse output signal of a certain amplitude and power can be obtained, and the number of pulses is equal to the number of gaps turned. This pulse signal is sent to a counter to be counted, and the angle at which the disc is turned can be known from the measured number of digits.

2. Absolute encoder: there are many optical channel engraved lines, each engraved line is arranged in turn with 2 lines, 4 lines, 8 lines, and 16 lines, and at each position of the encoder, by reading the pass and dark of each engraved line, a group of unique binary codes from the zero power of 2 to the n-1 power of 2 are obtained.

The incremental form can be understood as an increase in displacement.

The absolute value can be understood as the absolute position of the displacement.

It depends on how you replace it, what two coaxial jobs can do, and the rest is meaningless.

The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses indicates the size of the displacement.

Each position of an absolute encoder corresponds to a defined digital code, so its indication is only relevant to the start and end positions of the measurement, and not to the intermediate process of the measurement.

I am an automator and our factory uses a rotary encoder that converts the input of the machine into an electrical signal that can be processed by counters, tachometers, programmable logic controllers (e.g. PLCs) and industrial computers. The overall accuracy is relatively accurate.

These encoders convert mechanical inputs into electrical signals that can be processed by counters, tachometers, programmable logic controllers (e.g. PLCs), and industrial computers. The overall accuracy is relatively accurate.

Encoder: It is used by many spindle manufacturers, including our company. L+B's encoders entered the Chinese market early and are very popular in the domestic market due to their "Made in Germany" quality.

However, for us encoder debuggers, it also needs to be improved, for example, there is a layer of grease on the surface of the readhead of L+B (which should be related to the reading signal), and this layer of grease must not have scratches, otherwise it will have a certain impact on the encoder signal, so we must pay special attention when installing the encoder. In addition, the anti-magnetic interference ability of L+B's encoder is not good, and the tools used in installation must be demagnetized, which are all problems that L+B needs to solve.

Encoder: VS is also a German brand, our company is also new to contact, is at the exhibition acquaintance, and later their ** business came to our company to communicate. According to them, VS is also a German brand, completely made in Germany, and is the best merchant of European brands such as Fischer, Weiss, etc.

There is a complete replacement system for L+B, and L+B models can be provided for VS product replacement. Our company ordered 10 sets of samples for testing, after testing, there is no problem with the signal, and it has the following advantages compared with L+B: the encoder does not have a surface grease similar to L+B's readhead, so there is no need to worry about scratches; The anti-magnetic interference value of the encoder can reach 30kV, and the tool does not need to be degaussed, and can be applied to strong magnetic environments such as synchronous motors; The encoder has an automatic amplitude stabilization function for the first time, which allows us to adjust the signal by ourselves even if the installation angle and air gap are slightly off, which is also the feature we are most interested in, and it is convenient for installation.

At present, our company has ordered another batch of VS encoders, and we are verifying the possibility of replacing L+B, which is very likely in my opinion. There is also the VS detection box, which is really easy to use for encoder debugging or maintenance personnel, as said upstairs, at present, VS** provides us with a set of prototypes that are being tested, and the follow-up trial results will be fed back later.

3.Heidenhain encoder: The accuracy of Heidenhain encoder is undoubtedly the highest among all brands, but it is not generally expensive, VS or L+B can completely replace Heidenhain, so our company basically no longer uses Heidenhain encoder.
