If encoder cable is long, then termination may be required for stable readout of encoder. As rule of thumb, normally quadrature encoder cables shorter than 3 meters don't need termination. This might be different for serial data encoders, such as BiSS or SSI encoders because they usually carry higher frequency signals. However, if signal quality problems occur, then it is always advised to try termination as well as use of [[EMI suppression cores]]. | If encoder cable is long, then termination may be required for stable readout of encoder.
