下圖為開機波形
Trace-B captures the CAN bus signal(CANH-to-CANL),
Trace-A captures the TX output of servo drive
description:
1. when power on, PLC send a remote frame
2. servo drive acknowledges, and responds a data frame
3. 1200us later, the PLC sends another remote frame, and servo responds again
4. immediately, the PLC sends a data frame, the servo acknowledges normally(I think)
5. after step4, the PLC send another remote frame again, and servo responds normally(I think)
Step 1~5 是每次開機都可觀察到的固定波形, 其後之波形則由另張圖描述之
