How to replace and adjust the rotary encoder2021

Rotary encoder is a kind of precision electronic components, so some failures and damages may occur in long-term operation, which are all things with longevity. The best way is to replace and adjust the rotary encoder. Replace with a new rotary encoder.

Let's introduce the specific replacement steps of the rotary encoder:

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

Step 2: Loosen the mounting screws of the rotary encoder;

Step 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;

Step 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 rotary encoder;

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

Step 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.
