The calculation formula of the CAN baud rate at the top, and set the phase buffer 1, phase buffer 2, and prescaler at the same time. Disable automatic message retransmission: CAN communication is generally automatically retransmitted if the transmission is unsuccessful. If the data is sent ...
Example: • Condition − The secondary sample point (SSP) = 80% − CAN FD baud rate (CanControllerFdBaudRate) = 2.5 Mbps FD BitTime = 1/(2.5 * 10^6) s/Bit = 0.4 * 10^(-6) = 400 ns • Calculation formula CanControllerTrcvDelayCompensationOffset = (SSP%) * FD BitTime =...
There's an example how to set baudrate based on the amount of tq and the desired sync point. It's for SAMC21 but I believe the CAN controller is about the same. So the formula you are rather looking for is: total_tq = sync_seg_tq + (phase_seg1_tq+1) + (phase_seg2_tq+1)...
The necessary calculation is done by the servo controller. Consequently it is possible to enter values directly in e.g. millimetre per second if a linear drive is used. The conversion is done by the servo controller using the Factor Group. For each physical value (position, velocity and ...
when the two data transmission modules perform data transparent transmission. In the data transparent transmission mode, a response is generated for each message, so the effective data transmission rateVfneeds to remove the bandwidth occupied by the protocol. The calculation formula ofVfis as follows:...

Firstly, the above errors are caused by the unmatched rate clock instead of the Serial Clock, the rate clock formula is below.Next, the number of Time Quanta is the sum of 1 + (PSEG1 + 1) + (PSEG2 + 1) + (PROPSEG + 1).I think this information can explain your question.In ...
