What matters should be paid attention to when repairing and replacing the rotary incremental encoder?

　　 Rotary incremental encoder is a kind of precision electronic components, so some failures and damages may occur in long-term operation. At this time, it is necessary to adjust or replace the rotary incremental encoder. So what matters should be paid attention to when repairing and replacing the rotary incremental encoder? Incremental rotary incremental encoder should pay attention to three parameters:

1. Mechanical installation dimensions, including positioning stop, shaft diameter, installation hole position; cable outlet method; installation space volume; whether the working environment protection level meets the requirements.

2. Resolution, that is, the number of pulses output per revolution when the encoder is working, and whether it meets the design and use accuracy requirements.

3.Electrical interface, encoder output methods commonly include push-pull output (F type HTL format), voltage output (E), open collector (C, common C is NPN type tube output, C2 is PNP type tube output), long-line driver Output. Its output mode should match the interface circuit of its control system.

What matters should be paid attention to when repairing and replacing the rotary incremental encoder? Specific replacement method:

Remove the back cover of the motor and the back cover of the rotary incremental encoder; loosen the mounting screws of the rotary incremental encoder; rotate the rotor shaft of the motor so that the logo on the rotor of the rotary incremental encoder coincides with the logo on its shell; Remove the rotary incremental 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 incremental encoder; rotate the new encoder so that the two signs of the encoder overlap; press Install the encoder in the reverse order above.

What matters should be paid attention to when repairing and replacing the rotary incremental encoder? Maintenance notes:

　　 1. In the process of installing the encoder, 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 incremental encoder according to the mark on the rotor shaft of the motor. The drive parameters can be adjusted to set an offset value.

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

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