Description

ABB DP620 3BHT300016R1

Encoder output signal type

Under normal circumstances, the signal level obtained from the photoelectric detection device of the encoder is low, and the waveform is irregular, and can not be directly used for control, signal processing and long-distance transmission, so it is also necessary to amplify and shape the signal in the encoder. The processed output signal is generally similar to sine wave or rectangular wave, because the rectangular wave output signal is easy to be processed digitally, so it is widely used in the control system.

The signal output of the incremental photoelectric encoder includes open collector output, voltage output, line-driven output and push-pull output.

The open-collector output is an output circuit with the transistor emitter of the output circuit as the common end and the collector suspended. Depending on the type of transistor used, it can be divided into NPN collector open output (also known as leaky output, when logic 1 output voltage is 0V) and PNP collector open output (also known as source output, when logic 1, output voltage is the supply voltage) two forms. This type of output circuit can be used in cases where the encoder supply voltage and the signal receiving device voltage are inconsistent.

The voltage output is based on the open collector output circuit, and a pull-up resistor is indirectly installed between the power supply and the collector, so that there is a stable voltage state between the collector and the power supply, as shown in Figure 2-5. This type of output circuit is generally used when the encoder supply voltage and the signal receiving device voltage are consistent.
