Rotary encoder pulse reason?

Rotary encoder to generate pulse, what reason be cause? We can from the following three aspects to analyze: first, is the main reason is the problem of pulse receiver, as a result of high pulse frequency and loss, etc. ; Second, is the cause of the encoder itself, mainly machinery with environment temperature is too high, cause the encoder doesn't work normally. Third, the rotary encoder is damaged. Rotary encoder using note 1. Don't to shaft rotary encoder installation considerations exert direct impact. Rotary encoder shaft connected to the machine, you should use the flexible connector. In a shaft connector, don't press hard into the. Even if the use of connectors, because bad installation, may also be added to the axis of is greater than the permissible load load, or dial the core phenomenon, therefore, pay special attention to. Bearing life related to the conditions of use, affected by the bearing load of extremely large. Such as bearing load ratio regulation load is small, can greatly extend the life of the bearing. Don't disassemble rotary encoder, doing so will hurt oil and drip proof performance. Drip-proof type product is unfavorable and long-term immersion in water, oil, when the surface of water, oil should be wiped clean. 2. Rotary encoder to use to avoid vibration and vibration on the rotary encoder, can become false pulse. Therefore, to set the place, the installation place. The more the number of pulses per revolution happened, the narrower the rotating slots of the disk slot interval, the more susceptible to the effect of vibration. In low-speed rotation or stops, and spin groove on the shaft or the ontology of vibration disc jitter, pulse error may occur. 3. Rotary encoder wiring and false wiring connection considerations, it might damage the internal circuit, so when the wiring should take note: 1, wiring shall be carried out under the power OFF state, when power on, if the power supply output line contact, sometimes will damage the output circuit. 2, if the wiring error, sometimes will damage the internal circuit, so the wiring should take note the polarity of the power supply, etc. If 3, and the high tension line, power line parallel wiring, sometimes is induced into damage caused by misoperation, so let's separate wiring separately. 4, extension cord, should be under 10 m. And because the wire and the distribution of capacity, waveform of rising and falling time is longer, there is a problem, use schmidt circuit of waveform shaping, etc. 5, in order to avoid induced noise, etc. , to use the shortest distance wiring. To the integrated circuit input, need special attention. 6, wire, conductor resistance and the influence of the capacitance of the line, the waveform of rising and falling time lengthen, prone to interference between signals ( Crosstalk) Small, so the application of resistance, the line between the capacitance (low wire Twisted-pair cable, shielded wire) 。 Shanghai electronic products company specializing in the production of rotary encoder for 27 years, the products are widely used in automotive electronics, home electronics, multimedia, mixer, interphone, electronic toys, household electrical, aerospace, military industry and other fields, has for years been in perfect quality favored by domestic and foreign customers consistent high praise, the company has advanced production equipment and testing equipment, looking for a rotary encoder for electronic manufacturers.
