Steps and precautions for replacing the rotary encoder2021

When the rotary encoder fails and wears out for a long time, which affects the normal use, we must consider replacing the rotary encoder. In the process of replacing the encoder, the installation and use of the encoder should be strictly in accordance with the instructions for use. Talk about the rotary encoder replacement steps and the precautions for replacing the rotary encoder, and the rotary encoder use specifications.

The steps to replace the rotary encoder are as follows:

1: Remove the back cover of the motor and the back cover of the encoder;

2: Loosen the mounting screws of the encoder;

3: Rotate the rotor shaft of the motor so that the logo on the rotor of the rotary encoder coincides with the logo on its shell;

4: Remove the rotary encoder. At this time, you need to pay special attention to use special screws to push it out when loading and unloading, so as not to damage the encoder;

5: Rotate the new encoder until the two marks of the encoder coincide;

6: Install the encoder in the reverse order above.

Note for more rotary encoders:

1. In the process of installing the encoder, it is necessary to ensure that the rotor of the motor is different, otherwise the relative position of the rotor will be lost. If the relative position is lost, the old motor needs to use an oscilloscope to adjust the installation position of the encoder, and the new motor can judge the installation position of the rotary encoder according to the mark on the motor rotor shaft. When adjusting the installation position of the rotary encoder, it can be adjusted mechanically or adjusted. Drive parameters to set an offset value.

2. When changing the rotary encoder, pay attention. After the encoder is installed with the fixing screw, the jack screw on the coupling must be loosened and the jam caused by the assembly stress must be eliminated. dead.

3. It is necessary to pay attention to the wiring sequence of the encoder, if it is reversed, it may run over-current fault.

Rotary encoder usage specification

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 use of the rotary encoder specification.

1. Installation should be cautious to avoid impact

Rotary encoder is used in connection 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.
