How to Perform Quadrature Encoder Measurements
2023 / 02 / 07
Based on PC data acquisition, measurement is performed through a combination of modular hardware, application software, and a computer. Although data acquisition systems have different definitions based on different application requirements, the purpose of each system to collect, analyze, and display information is the same. The data acquisition system integrates signals, sensors, actuators, signal conditioning, data acquisition equipment, and application software. Encoder and Application Overview <br> The encoder is an electromechanical device that can be used to measure mechanical motion or target position. Most encoders use optical sensors to provide electrical signals in the form of pulse trains, which in turn can be converted into motion, direction, or position information. Rotary encoders can be used to measure the rotational movement of the shaft. Figure 1 shows the basic components of a rotary encoder, including a light emitting diode (LED), a code wheel, and a light sensor on the back of the code wheel. This code wheel is placed on a rotating shaft with opaque and light-transmitting fan-shaped areas arranged in an encoded form. When the code wheel rotates, the opaque sectors block light, and the light-transmitting sectors allow light to pass through. This produces square-wave pulses that can be compiled into corresponding position or motion information. The encoder is usually divided into 100 t
Servo motor encoder absolute and incremental difference
2023 / 01 / 23
An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a form that can be used for communication, transmission, and storage. The encoder converts an angular displacement or a linear displacement into an electrical signal, the former being called a code wheel and the latter being called a code ruler. According to the readout mode, the encoder can be divided into contact type and non-contact type; according to the working principle, the encoder can be divided into two types: incremental type and absolute type. The incremental encoder converts the displacement into a periodic electrical signal, which is then converted into a counting pulse, and the number of pulses is used to represent the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the start and end positions of the measurement, regardless of the intermediate process of the measurement. Incremental servo motor encoder introduction Incremental coding In addition to the ABZ signal of the ordinary encoder, the incremental servo encoder also has a UVW signal. Most of the domestic and early imported servos use this form, and the lines are more.
2022 / 11 / 18
Absolute encoder The rotary incremental encoder outputs a pulse when it is rotated, and its position is known by the counting device. When the encoder is not moving or power is off, the internal memory of the counting device is used to remember the position. In this way, when the power is off, the encoder can't have any movement. When the caller works, the encoder can not interrupt and lose the pulse during the output pulse. Otherwise, the zero point of the counting device will shift, and this bias The amount of shift is unknown, and only the wrong production result can be known. The solution is to increase the reference point, and the encoder corrects the reference position into the memory position of the counting device every time the encoder passes the reference point. Before the reference point, the accuracy of the position cannot be guaranteed. For this reason, in the industrial control, there are methods such as finding a reference point for each operation, and starting to change the zero. For example, the positioning of the printer scanner is the incremental encoder principle. Every time we turn it on, we can hear a bang, it is looking for the reference zero, and then it works. This method is more troublesome for some industrial control projects, and even does not allow booting to change to zero (you must know the exact position after booting), so there is an absolute encoder.
Reflective encoder technology for portable medical device design
2022 / 10 / 25
Reflective encoder technology for portable medical device design In the past few years, many semiconductor companies have gradually focused on the medical device market. Emerging application trends in the medical field are increasingly demanding technology, and designers are beginning to develop highly competitive products for a variety of needs. For example, the demand for home medical equipment is growing very fast. This is in line with two trends: the public's awareness of the advantages of self-management medical care is becoming more common, and outpatient treatment is less expensive than hospitalization. These trends are continuing to drive healthcare companies to develop products that are easier to carry, less expensive, and easier to use. Currently, there are many different diagnostic and therapeutic devices in the outpatient treatment market, such as dialysis equipment, portable insulin pumps, insulin inhalers and diabetes management systems. The emergence of these self-service medical devices has also prompted device manufacturers to introduce innovative products. Therefore, product designers are all looking for new component products that can support innovative thinking and future medical product development trends and can meet the rapid market development strategy. In particular, the miniature reflective encoder technology has become an effective boost for portable medical device manufacturers to break through existing accuracy, power consumption, size
Application of High Precision Rotary Encoder in Servo Feedback Positioning System
2022 / 10 / 21
It is basically a double brush orthogonal unbounded potentiometer. It has a full circular ring of resistive material that is electrically connected at both ends where two electrically independent brushes move. The two brushes are mechanically connected to each other by a 90° angle. Rotary encoders are often used in positioning systems with servo feedback. In this case, the cost of the encoder is generally not important. However, the encoder can also be used to encode the position of knobs on some user interfaces, such as the volume knob on an audio system. For these knobs, potentiometers can be selected for low-cost, high-precision, and absolute-reading values, but their travel is limited, typically to less than 340°, or optomechanical rotary encoders are available. Their travel is not limited, but the price High, low accuracy, only relative readings. This design example attempts to combine the two, with the advantages of the potentiometer, as well as the characteristics of the optical machine rotary encoder boundaryless operation. The encoder uses the structure technology of the standard potentiometer, so it is easy to produce. It is basically a double brush orthogonal unbounded potentiometer. It has a full circular ring of resistive material that is electrically connected at both ends where two electrically independent brushes move. The two brushes are mechanically connected to each other by a 90° angle (Figure 1). The AD
Servo motor phase and encoder position adjustment
2022 / 08 / 24
Servo motor phase and encoder position adjustment The mainstream servo motor position feedback components include incremental encoders, absolute encoders, sine and cosine encoders, and resolvers. Phase Alignment of Incremental Encoders In this discussion, the output signal of an incremental encoder is a square wave signal, and it can be divided into an incremental encoder with a commutation signal and an ordinary incremental encoder. Ordinary incremental encoders have two-phase orthogonal square-wave pulse output signals A and B, and zero-bit signal Z; in addition to the ABZ output signal, incremental encoders with commutation signals have a mutual difference of 120 degrees. The number of revolutions per revolution of the electronic commutation signal coincides with the number of pairs of magnetic poles of the motor rotor. The alignment of the phase of the UVW electronic commutation signal of the incremental encoder with a commutation signal and the phase of the rotor pole or the phase of the electrical angle is as follows: 1. Use a DC power supply to pass the motor's UV winding with a DC current less than the rated current, U in, V out, and orient the motor shaft to an equilibrium position; 2. Observe the U-phase signal and Z-signal of the encoder with an oscilloscope. According to the convenience of operation, adjust the relative position of the encoder shaft and the motor s
