1. Question: What are the precautions for the selection of incremental rotary encoder?

Need to pay attention to four parameters.

1. The mechanical installation dimensions of incremental rotary encoders, including positioning stoppers, shaft diameters, and mounting hole positions, are the cable-line method installation space volume and the protection level of the operating environment meets the requirements.

2. The resolution of the encoder, that is, whether the number of pulses output per revolution when the encoder is working meets the requirements of the design accuracy.

3. Electrical interface and encoder output methods often include push-pull output (f type), voltage output (v), open collector (n, common n is NPN output, p is PNP tube output), and long-line driver output. Its output mode must be consistent with the interface circuit of its control system.

2. Question: Please tell me how to use incremental rotary encoder.

1. Incremental rotary encoders have different resolutions. The number of pulses generated per week is used for measurement. The number ranges from 50 to 48000 or more. The more pulses, the higher the resolution. This is one of the important basis for selection.

2. Incremental encoders usually have three systems of signal output (there are six systems of signals for differential): ab and Z generally use ttl level, A pulse in front, B pulse after B pulse, ab pulse difference of 90 degrees, sent out every week A Z pulse is generally judged by referring to the mechanical zero with a leading b or ultrasonic before a. The company’s incremental encoder is defined as the encoder rotates clockwise from the shaft end, a leading b is 90°, the opposite is reverse The hour hand is reversed and a is 90° before ultrasound. There are also different situations, please see the product description.

3. Incremental rotary encoder uses plc to collect data, and can choose high-speed counting module; uses industrial computer to collect data, can choose high-speed counting board; uses single-chip microcomputer to collect data, and it is recommended to choose input port with photocoupler.
