Hunan Code Disc Manufacturer: How to Judge Common Faults of Encoder
Hunan Code Disc Manufacturer: How to Judge Common Faults of Encoder In many cases, the encoder is not bad, but only the main cause of intrusion. The waveform is not very good, resulting in counting prohibition. Please tell me how to distinguish? The encoder is a meticulous component, which is mainly due to the serious intrusion around the encoder, such as whether there is a large motor, DC welding machine continuously starting to produce intrusion, whether it is transmitted in the same pipeline as the power line, etc. It is also very important to choose which kind of export opposite intrusion. Generally, it is better to export the power with opposite direction signals to resist intrusion, I .e. A ~ A- ,B ~ B- ,Z ~ Z-, which is characterized by the addition of 8-wire switching power supply instead of 5-wire (total zero). The transmission of power with reverse direction signal in the cable is symmetrical and less intrusive, and discrimination can be added to the receiving equipment (for example, when the receiving machine equipment signal uses the 90 phase angle of A and B data signals, and when the pulse signals 10, 11, 01 and 00 are seen, it is counted as an effective single pulse, and this method can effectively improve the anti-intrusion characteristics of the system). Even the encoder has its advantages and disadvantages. The data signal output of the internal power supply circuit of the code disc electronic device chip is very different. Otherwise, how can a 1000 line increase?

Hunan code disc manufacturer: talk about the working principle of encoder code disc
Hunan Code Disc Manufacturer: Let's talk about the working principle of encoder code disc. It is manufactured by etching. Its advantages are no die drawing, high precision punching, vertical wire frame and no burrs. There are basically: 100/200/256/300/360/400/500/512/600/720/800/1000/1024/1200/2000/2048 and other single pulses. The code disc made of metal materials is generally 100-1024 single pulses, which are generally determined according to the diameter of the code disc and the thickness of the metal composite material. In CG, 2048 single pulses can be achieved. Due to the high precision above 2048, most of them use laminated glass code discs, but laminated glass code discs are far inferior to metal code discs because of their coaxiality, easy breakage and high cost. (Screen printing screen code plate can be achieved, but considering its reliability, precision and service life is far less than metal materials and glass, it is not recommended). Metal material code plate selection: generally use sus304 raw materials imported from Japan, thin and thick 0.05/0.08/0.1/0.15/0.2, etc. Provisions: CG basic tolerance -0.01mm, well-proportioned diameter position, no burrs.

Hunan Code Disc Manufacturers: Talk about the Characteristics of Code Disc and Encoder
Hunan Code Disc Manufacturer: Tell me about the characteristics of the code disc and encoder. The encoder refers to the encoder that accurately measures angular velocity data. Encoders compose and convert signals or data into devices that can be used to communicate, transmit, and store data signals. The angular velocity or vertical deviation is converted into an electronic signal. The front one is called an encoder and the back one is called a code ruler. According to the loading method, the encoder can be divided into two types: contact and non-contact; according to the basic principle, the encoder can be divided into two types: incremental and positive. The incremental encoder converts the deviation into a regular electronic signal, and then converts this electronic signal into a counting pulse, and uses the total number of pulses to describe the size of the displacement. Each position of the positive encoder matches a formulated digital code, so its measurement range is only related to the start and stop positions of accurate measurement, and is irrelevant to the whole process of detection. What is a serial number? For example, a phone will be a contact information, a postal code is required to send a letter, etc. These are all serial numbers. Generally speaking, the whole process of using data or some kind of text identification to represent the power of an overall target or signal is called a serial number. The decimal serial number or the serial number of some kind of text graphic cannot be realized by circuit. Hunan code disc manufacturer: code disc and coding

Grating manufacturers tell us what grating is like. How to operate?
The grating manufacturer said that the grating operator needs to follow the mechanical operation specifications, strictly abide by the operating procedures, and prohibit overload operation. The grating manufacturer said that the grating, as a product with safety certification, consists of two parts. The transmitting machine emits modulated infrared light, which is received by the receiving machine to form a protective net. When an object enters the protective net and the light is blocked by the object, the receiving machine circuit immediately responds by the internal controller, that is, the output signal. There is a very wide range of applications. For example, the contact safety door is installed on the stamping equipment that needs continuous feeding and taking, and the operator needs to switch the door frequently, which not only increases the workload of the operator, but also reduces the production efficiency. In this case, the grating and is a good choice. When the operator is sending and taking materials, as long as any part of the body blocks the light, the machine will enter a safe state and will not cause harm to the operator. The density of the light beam determines the size of the body part that can be detected by the light screen. According to ergonomic data, the diameter of an adult's fingers should be no less than 14mm, the thickness of the palm should be no less than 30mm, and the diameter of the wrist should be no less than 40mm. Therefore, the safe detection interval can be divided into 10mm, 14m

Grating manufacturers tell you about grating is how to work?
The grating manufacturer said that the multi-beam safety grating is a kind of safety sensor, which can realize early warning, alarm and normal work by delimiting a certain range in the grating scanning area. After power-on, use the new software to establish a new project and delimit the project safety warning area and safety area. Safety area detection is based on the grating in the coding device to calculate the range you specify. At the same time, the multi-beam safety grating can be divided and calibrated according to the needs of the site, with more than 8 areas. Prevent people or obstacles from entering the danger area and provide early warning and warning. There are five lights above the grille. Displays the working status. When delineating a safe zone, the safe zone should be larger than the safe zone. But early warning does not affect production and will make indifference the norm. When someone enters the alarm area, an alarm will be issued and the equipment will stop working. The grating manufacturer said that the warning light is yellow, the alarm is red, the pollution light is on the right, and the two green indicator lights are normal. If there is pollution, the dust on the surface of the grille should be cleaned to make it work normally. In an emergency, the alarm can be reset by resetting. If the reset fails, the mirror can be recalibrated by learning the software. After receiving the next step, signal processing is performed. Therefore
