text: <s>[INST] Encoder Noise Feedback Greetings, I have a customer with a unique Torque Prove application. They have installed the PF700 and encoder, along with the cables. The issue is that the encoder feedback cable and drive power cables run in the same cat track and due to the unique nature of this mobile hoisting system they cannot separate the cables. They have been considering using an Encoder Filter by Cognito Quam www.cognitoquam.gr (I have never heard of this company). Someone else suggested the use of a reflective wave filter on the power cables to help mitigate the noise. My thought was possibly looking at a Sine Wave Filter. Anyone else have any suggestions, or have delt with a similar application? Cheers. [/INST] there really is no good solution. you can try shielded motor leads and shielded encoder cable at least... then ferrite core on the encoder cable with probably a bleed winding thu the core to ground... but its still gonna be ugly. \\n </s>
