About encoder output signals

2022-09-17

Rotary encoder is used to measure the speed of the device, everyone in the actual operation of the application process, will come into contact with the rotary encoder output signal type, I do not know whether you know these types? Today to popularize (refers to all over, throughout the general) under this knowledge. General encoder output signal in addition to the A, B two-phase, every turn also output a zero pulse Z. SSI signal conversion display is suitable for all kinds of winch, screw starter gate lifting height measurement. When the spindle rotates in clockwise direction, it outputs pulses according to the following figure, and the signal of A channel is located before the B channel; when the spindle rotates counterclockwise, the signal of A channel is located after the B channel. The signal of channel A is located before channel B. When the spindle rotates counterclockwise, the signal of channel A is located after channel B. Thus, it can be determined whether the spindle is rotating forward or reverse. Zero Position Signal of Rotary Encoder The encoder sends out one pulse for every one-week rotation, which is called zero pulse or mark pulse, and the zero pulse is used to determine the zero position or mark position. The zero pulse is used to determine the zero position or marking position. The zero pulse is measured accurately regardless of the direction of rotation...

Four types of delayed introduction to absolute encoders

2022-09-17

Encoder latency depends on the bandwidth of the analog (definition: a virtualization of a real thing or process) amplifier, its internal interpolating interpolation processing, resolution, and the encoder interface it uses. I. Interpolation interpolator delay If the analog encoder signal sine/cosine interpolation interpolation interpolation is an MCU/DSP based system, the delay period may exceed 200us or more. Particular attention should be paid when higher frequencies and resolutions are used, especially for synergistic multi-axis control and redundant systems. In such cases, delays can cause (enable, enable) position data to be perhaps not current or not synchronized. To meet this challenge, an ultra-fast flash-based interpolating interpolator can take on this task. iC-NV is a parallel internal processing, can be obtained with a delay of less than 1us interpolating interpolator. Encoder Interface Latency When a serial encoder interface is used, it is the data transfer time that usually only plays an important role. Absolute encoders ...

Encoder Installation: Connecting Absolute Encoders to PLCs

2022-09-17

As we know, absolute encoder encoder is a kind of rotary measurement device, it will be measured by the angular displacement directly into a digital signal. Therefore, we will be in the application of the rotary encoder output pulse signal directly into the PLC, the use of high-speed counter on the PLC pulse signal counting, in order to obtain the measurement results. It is important to note that the number of phases of the rotary encoder outputs is different for different models of rotary encoders! Some rotary encoders output A, B, Z three-phase pulses, some have only two phases, A and B, and the simplest has only A phase. Encoder mounting high-speed end mounting can fully use the full range and improve the resolution. Tie rope displacement sensor is a linear displacement sensor in the structure of the delicate composition, fully combines the advantages of the angle sensor and linear displacement sensor, to become a small installation size, compact structure, large measuring stroke, high precision sensors, the stroke from a few hundred millimeters to more than a dozen meters ranging. Application we will...

High-precision domestic encoder manufacturer product customization (mass production) introduction

2022-09-16

In the past few years, the domestic encoder in the gradual rise, especially high-precision encoders, technology has also made new breakthroughs. In the many domestic encoder manufacturers, there has been a complete realization of the "localization" of the encoder brand, we are a realization of the "full localization" of the encoder supplier. "Full localization" encoder, for the civilian does not seem to have much significance, but for the military industry, it is a great breakthrough, purely domestic encoders do not receive the shackles of foreign countries, can greatly support the domestic military industry. West Verdi encoder using customized strategy to provide high-precision encoders, starting from the high-end encoder replacement. Some special positions are generally imported encoders in the work, we start from this point, non-destructive replacement. Domestic encoders are now fully capable of one-to-one replacement, and this point also requires purchasing companies to pick up confidence in domestic encoders. Over the years, high-end high-precision encoders are imported brands of the market, domestic encoders...

Kuebler Kuebler encoders for local replacement of non-destructive solutions online

2022-09-15

Kuebler Kuebler encoder, is an excellent German product, in the field of automation performance. Many domestic industries have used or are using Kuebler encoders, Kuebler encoders in the European encoder industry occupies an important seat. Recently, some customers inquire about the domestic substitution of Kuebler encoder. Due to, the current market known reasons caused by some imported brands need to be replaced, either a long period of time, or delivery is difficult and so on. The use of domestic encoders is also in line with the trend of domestic substitution. For the non-destructive replacement of Kübler encoders, we give the following solutions. Alternative solutions: 1, according to the use of parameters to customize the corresponding encoder products for alternative use; 2, already in use, you can directly send the encoder model to re-customize the production of the corresponding encoder products. Quality: 1, we suggest the first customization, take a small amount of customization,...

Baumer encoders for local replacement solutions

2022-09-13

Baumer encoder is a very good brand, in many mechanical control in the performance of the very good. Baumer encoder is highly favored at the same time, but also reflects a serious shortcomings: is too long lead time. Recently, a company pointed out that Baumer encoder delivery period and extended, has affected the company use. The new crown and the international situation and other reasons, caused by the Baumer encoder delivery period is long, this point for the domestic enterprise users is an insurmountable gap. After receiving procurement inquiries, we gave a solution and shipment in 7 working days. In general, we can customize the corresponding encoder according to the demand, to replace the imported encoder. Before, many friends worry about the quality and stability.

Encoder Installation Steps and Installation Precautions

2022-09-12

Encoder is a precision measurement of angular displacement based on the principle of electromagnetic induction sensor, can be used to measure the speed of mechanical devices can also be used for speed regulation of mechanical devices, and sometimes the speed of machining needs to be changed can use the encoder to work. Then how to correctly install the encoder it Encoder installation installed after the installation of reduction gear, such as the shaft end of the winch rope drum or the last section of the reduction gear shaft end, this method has been no gear back and forth clearance, the measurement of the more direct, higher precision, this method is generally measured over long distances, for example, a variety of lifting equipment, feeding trolleys positioning. Absolute encoder code value" with the measured "position" corresponds to a unique, with "power failure memory" function, no rotary measurement of accumulated errors, in "a cycle of "It is superior to the incremental encoder in the field of measurement and control, and the range can be adjusted by adding a front reduction gearbox. The encoder also has a shielded wire, the use of the shielded wire should be grounded to improve anti-interference. Encoder installation steps and ...
