P-IHM03 Communication

[1366820688qqcom]

When I parse the data sent according to the motor protocol, I find that it is completely different from what is written on the protocol. I am using st's P-IHM03 motor communication board, but when I want to communicate with STM32G431, I can't compare his data with the protocol. The data I sent is on page 22 of the document, and the other picture is what I sent, but it doesn't seem to correspond, so I asked the big guys to help me parse the data bytes. TX: 85 FF FF BF RX: 05 C7 01 14 But I don't know what each bit means!!!
