5.2.3. Encoder

 

If there is an error with the encoder, it may cause position deviation, malfunction, runaway, etc., and it may cause shaking during stop and irregular cycles (pulsation). Those problems are not related to the phenomenon of mechanical abnormal sound, heat generation, vibration, etc.

 

 

n  Investigation method

 

①    Check if there is any problem with the encoder data.

②    Set the customized scale to the reference position, and then investigate whether there is an error with the position data.

③    Move each axis of the positioner and investigate whether there is any axis whose data changes irregularly.

④    Replace the servo amplifier circuit board BD440, and then investigate whether an error occurs.

 

n Handling method

 

①     Check the wiring and replace the encoder if the wiring is not disconnected.

②     If the error does not occur when the servo amplifier circuit board BD440 is replaced, it should be replaced.
