i want to use "position axis"command of MCC.

to move axis_A to axis_B.basicmotion.position,but,once set move ,the CPU must in STOP.

check the axis positon ,axis_a and axis_B position the same in the value ,but actual position in not the same (fisish home is not settle).

how can i do it ?

Not sure what you are trying to accomplish.

axis_B.basicmotion.position is the actual position of your axis_B.  The  _POS command needs a position reference, so I'm not sure what you are trying to do is legal.

What does your Diagnostic Buffer say about why you went into STOP mode?

Axis_A and Axis_B is virtual axis.

i can see the Diag Buffer is overtime .

i do not SIMOTION can do it or not ?

once run the command ,state of Axis_B can go,two axis positon is the same ,but trace curve is not the same . 

look at the picture,yellow is axis_A,green is axis_B ,normal ,two curve must the same .

the command ,absolute can not run ,but relative can run .

 the problem is OK.

at the picture ,"delay program execution"is set has error , use "motion start" is OK.
