The sensor includes linear encoder and rotary encoder, which is used for the position measurement of speed, displacement and angle. Yuheng optics can provide rotary encoders based on optical, magnetic and gear principles, linear encoders based on optical principles and supporting products.
At present, the encoder used in elevator is mainly incremental encoder, which is used together with frequency converter or other speed control system to provide speed and position information for speed control system or control system. Generally, frequency divider is added for pulse equivalent conversion. Encoder installation is mainly coaxial connection with traction motor to measure speed and feedback of motor. Now the door motor of frequency conversion door system is also equipped with...
In practice, the faults caused by rotary encoder are not a few, and it is quite troublesome to check. Sometimes, although it has been checked, it is still not reassuring. Therefore, I would like to introduce a simple method to confirm the rotary coding fault. From the schematic diagram of the drive and regulation system, it can be clearly seen that it is because of the rotary coding that the microcomputer inverter motor is between. If there is a problem with the rotary encoder, the abnormal...
An encoder is a device that compiles signals (such as bit streams) or data and converts them into signal forms that can be used for communication, transmission and storage.Encoder converts angular displacement or linear displacement into electrical signals, the former is called code wheel and the latter is called code scale.
Manual sensor posital encoder The encoder corrects the reference position into the memory position of the counting device every time it passes the reference point. Before the reference point, the accuracy of the position cannot be guaranteed. For this reason, in industrial control, there are methods such as finding the reference point first, turning on the machine and changing it.
Incremental encoder usually has three signal outputs (there are six signals in difference): A,B and Z, which generally adopt TTL level, A pulse is in front, B pulse is behind, A and B pulses differ by 90 degrees, and a Z pulse is sent out every turn, which can be used as a reference mechanical zero position. Generally, A leads B or A before B-ultrasound is used for direction determination. The incremental encoder of our company is defined as the clockwise rotation of the encoder as forward...
Dual concentric rotary encoder Incremental encoder usually has three signal outputs (there are six signals in difference): A,B and Z, which generally adopt TTL level, A pulse is in front, B pulse is behind, A and B pulses differ by 90 degrees, and a Z pulse is sent out every turn, which can be used as a reference mechanical zero position. Generally, A leads B or A before B-ultrasound is used for direction determination. The incremental encoder of our company is defined as the clockwise rotation...
Gear sensor rotary encoder incremental The incremental rotary encoder has the difference of resolution, which is measured by the number of pulses per turn, ranging from 6 to 5400 or higher, and the more pulses, the higher the resolution; This is one of the important basis for selection.
Generally, the signal obtained from the photoelectric detection device of the encoder is low in level and irregular in waveform, and cannot be directly used for control, signal processing and long-distance transmission, so it is necessary to amplify and shape the signal in the encoder. The processed output signal is generally similar to sine wave or rectangular wave. Because the rectangular wave output signal is easy to be digitally processed, it is widely used in control system. The signal...

Encoders can be divided into contact type and non-contact type according to the reading mode. According to the working principle, encoders can be divided into incremental and absolute types. Incremental encoder converts displacement into periodic electrical signal, and then converts this electrical signal into counting pulse, and the displacement is expressed by the number of pulses.
