The encoder frequently asked questions！

1. How to take the encoder when the origin is reversed? For example, if you want to reverse 100 points, how to set this data in the programming software, the data read is 8000000100, how to understand this data!
Explanation: 8 is the sign bit.

2. How far can the encoder pulse data travel farthest?
Description: In theory, it can reach 100 meters. See how See how to row line.

3. the project requires the encoder to have a pulse output function when it is reversing, choose your company's encoder, do not know if it can meet the requirements?
Description: See how your equipment is required. The encoder has a pulse output as long as it rotates.

4. How to connected the absolute encoder and PLC?
Note: The output mode of absolute encoders is divided into two categories: one is serial output, which can be connected with PLC communication port; the other is common code output, generally Gray code, when connected with PLC Pay attention to the relationship between the pulse output frequency and the resolution of the PLC input port, so as not to lose the signal.

5. What is the cause of the pulse loss in the encoder?
Note: The first and main cause is the problem of the pulse receiver, such as the loss due to the high pulse frequency. Another reason is the encoder itself, mainly due to the high ambient temperature of the machine. The device is not working properly.

6. The encoder selects the model according to those conditions (for example, the contactor is selected according to the control voltage, load power, and current). Which encoder is selected according to those requirements?
Description: First determine the type of encoder, whether it is absolute value or incremental type (use is different); then confirm the resolution; then select the signal output mode, there are NPN output, voltage output, line drive output, no output, etc.; To choose the highest speed, shape, installation method, ambient temperature, degree of protection, etc.

7, I would like to ask the connection cable due to remote extraction of signals should pay attention to what problems, and your company sells this kind of cable?
Note: The cable length of the encoder is generally 0.5-3M, the cable length of the open collector output mode cannot exceed 10M, the line drive output can reach 200 M, and the signal line of the encoder cannot be strongly interfered with the power line. The lines are arranged in parallel and must be shielded.
