Release date: sensing technology co. , LTD. , zhejiang province _ encoder - 2017 4 - Browse: 525 times optical rotary encoder used to measure the rotational speed and cooperate with the PWM technique can realize fast speed regulating device, the encoder to introduce the optical rotary encoder is how to apply? The press is reviawed choose PLC control, automation degree are improved greatly. In the automatic control is partitioned by a command control machine segment to end, dividends will process combining a model of several control areas. But Lord make manipulation of the device's greatest flaw is not convenient debugging, tend to be tuned control area in the adjustment of another adjacent area will change, the result is all control the size cannot be accurately determined. Other, command control device also compare with complicated wiring, especially large-scale vulcanizer. Tire forming sulfide main motor rotates, reached optical rotary encoder through the reduction gear on the axis of rotation, drive the rotating disc rotating trough, the rotary encoder output pulse signal while working or gray code. No matter choose what kind of PLC control system, must have a high speed counter function, so that the rotary encoder output pulse counting. Note: installation of optical rotary encoder device when applying directly rushed out, please don't give shaft connected to the machine parts, please use the flexible shafts ( OMRON products with special shafts) 。 Vibration can produce pulse output error, a turn of the output pulse number, the more spin more narrow slots of the disk slot interval, the more easily affected by vibration. Therefore, the rational selection of pulse encoder output per week number is very important. Oscillation pulse output error happens, a turn of the output pulse number, the more spin more narrow slots of the disk slot distance, the more simple by the influence of the oscillation. In PLC programming, be sure to keep high speed counter module power problem solved. Otherwise will cause the current count value is missing, result in disorder of counting starting point. Therefore, reasonable selection of encoder ( Electronic hand wheel) The number of pulses weekly output is of crucial importance. Programming note in PLC programming, is bound to the high-speed counter module of power stick to handle the problem. Sensing technology co. , LTD. , zhejiang province, mainly produces incremental photoelectric encoder, magnetoelectric incremental encoder, photoelectric encoder, absolute type magnetoelectric absolute encoder, etc.
