Encoders

  • Sensorless operation is available (experimental) for applications with a minimum speed > 100RPM, see here for more information. For all other applications, encoder feedback for the motors position is required.

  • [1]: The ODrive Micro does not have a dedicated SPI MOSI pin. The encoder SPI MOSI must be connected to either VCC or GND depending on the model:

    • AMS, CUI, RLS Orbis encoders: Connect MOSI to VCC.

    • MA702/MA732 Encoders: Connect MOSI to GND.

  • [2]: Only 14-bit singleturn currently supported over SPI

  • [3]: Only 18-bit RLS AksIM-II and Renishaw RESOLUTE encoders over BiSS-C have been formally tested. As BiSS-C is a standardized protocol, other encoders and resolutions are theoretically supported, however this remains an experimental feature. If you use BiSS-C with an encoder or resolution not listed here, please let us know!

  • [4]: An external adapter circuit is required to connect the encoder’s differential clock and data signals to the ODrive’s single-ended GPIOs.
