Rotary encoder usage details

Rotary encoder is a sensor device used to measure speed, angle, displacement and distance. Because of its simple structure, high measurement accuracy, long life and other advantages, the encoder is valued and promoted at home and abroad. It is used in precision positioning, speed, Length, acceleration, vibration and other aspects are widely used. Let’s take a look today about what technical parameters you should know before buying and using a rotary encoder? Rotary encoder usage details.

What technical parameters should be known before the use of rotary encoder?

1. To understand the application in detecting objects, such as speed measurement, distance measurement, angular displacement measurement or counting.

2. To understand whether it is only used for dynamic processes or contains static positions or states.

3. It should be clear whether to choose an incremental rotary encoder or an absolute rotary encoder.

4. The range of motion of the object needs to be determined.

5. To understand whether to choose a single-turn absolute rotary encoder or a multi-turn absolute rotary encoder.

6. Need to know the maximum speed or frequency of the object.

7. To understand clearly the accuracy requirements of the object.

8. Need to understand the application parameters of selecting a rotary encoder.

9. Pay attention to the use environment, pay attention to the interface mode and protection level of the rotary encoder.

The conversion effect of the rotary encoder is very fast, but if you want to maintain such a good performance, you need to master the correct and reasonable operation method in the daily use process. Let's take a look at the details that are easily overlooked in the operation.

Rotary encoder usage details

1. Installation should be cautious to avoid impact

Rotary encoder is used as a device connected with other machinery. It is necessary to use a flexible connector when connecting to prevent the encoder from being accidentally hit by hard objects during installation. Most of the time, such collisions are difficult to recover from. It can be seen from the surface that the use of flexible connectors will not cause negative pressure to the encoder during installation.

2. Reduce the amount of vibration and prevent the occurrence of no pulse

If pulses occur during the use of the rotary encoder, it will seriously affect the conversion rate of the equipment. Incorrect connection of equipment, unreasonable operation of equipment, insufficient quality of equipment, influence of working environment, etc. will cause pulses in the encoder. Therefore, during installation, it is necessary to strengthen the inspection of whether the connection is loose, whether the operation method is correct, standardize the equipment installation place, and reduce the vibration frequency to prevent the occurrence of no pulse.

Three, wiring and connection

Inappropriate wiring will also affect the error in the use of the rotary encoder. Not only that, it will also cause serious loops inside the encoder and even burn out the wiring. Therefore, when the wiring is connected, the encoder must be turned off, the output and input power cords must be reasonably matched according to the corresponding colors, and the connection between the power line and the high-voltage line must be operated separately.

The above are the details that are easily overlooked in the daily operation and use of the rotary encoder. Only by doing these correct and reasonable operations can the performance of the equipment be guaranteed.
