1、Waytop？ The current consumption of encoder is within the power range of PLC.
2. If the Waytop encoder outputs in parallel and is connected to the I/O point of PLC, it is necessary to know whether the signal level of the encoder is push-pull (or push-pull) output or open collector output. If it is open collector output, there are two types: N-type and P-type, which need to have the same polarity as the I/O of PLC. If it is a push-pull output, there is no problem with the connection.
3. If the output of the road top encoder is a driver, the signal level is usually 5V. Be careful when connecting. Don't connect the power level of 24V to the signal wiring of 5V, which will damage the signal end of the encoder.
Extended data:
Formal classification
Shaft type: the shaft type can be divided into clamping flange type, synchronous flange type and servo installation type.
Casing type: Casing type can be divided into half-empty type, full-empty type and large-caliber type.
According to the working principle of encoder, it can be divided into photoelectric type, magnetoelectric type and touch brush type.
Encoders can be divided into incremental and absolute types according to the different ways of engraving holes on the code disk.
Incremental encoder converts displacement into periodic electrical signal, and then converts this electrical signal into counting pulses, and the number of pulses indicates displacement. Each position of absolute encoder corresponds to a certain digital code, so its indication value is only related to the starting and ending positions of measurement, and has nothing to do with the intermediate process of measurement.
