WebMay 23, 2024 · 3. The simplest way would be to implement the test in your design. Since you use a CAN bus, I'm assuming you have a main board and a motor driver board. You … WebThe bus signal is created electrically by applying a differential current into the two-wire bus system. By doing so, a differential voltage of 800 or 900 mVpp (where "pp" stands for "peak-to-peak") is generated on the bus. This is then also the nominal peak-to-peak amplitude (Vpp) of the signal that any Fieldbus device generates.
