Many Thanks, Charles.
Sorry for almost forgetting my post. Finally, I found the root cause that some of important M-variables's address configuration were lost such as open-loop mode bit, amplifier-enabled status bit, and home-complete bit.
I am also confused occasionally the coordination system definition's go into disorder(For example, &1: #1->X #2->Y #3->Z, change to &10: #1->X &11: #2->Y #3->Z) especially
after I tuned the motor PID parameters. When I redo the coordinate definition, PEWINPro32 2 pop a messagebox which says "best optimal value for I68 =0".
