As showed in the image which is cutted from the file of 5axis_sim.hal..
" net J0pos <= axis.0.motor-pos-cmd"
"net J0pos => axis.0.motor-pos-fb"
is the two "net"sentence above equal with this sentence directly:"axis.0.motor-pos-cmd => axis.0.motor-pos-fb"???
if equal, how we should understand it by the data from "axis.0.motor-pos-cmd" to "axis.0.motor-pos-fb"?
if not equal, where's the difference??

This is because you have chosen a "simulator" configuration that will run without any hardware.
The feedback is short-circuited so that the simulated machine does not have an immediate folowing error.
Yes, absolutely. But if there is no motor and no encoder then it can't.

but the point i cannot understand is that why the pin of "axis.0.motor-pos-fb" accept data from "axis.0.motor-pos-cmd "

isn't the data of "axis.0.motor-pos-fb" from the encoder which is attached with the motor?
Yes, absolutely. But if there is no motor and no encoder then it can't.
