Hi again,

I quickly made a setup running motor 6-4-2 release. The problem is still
there. 
But I seem to get a little clue. 

I have 3 three such controllers and two works just fine. With the well
functioned
controller, when one axis is reported as "motor in moton", I try to move
any 
other axis and this axis will end up with MIP=0x420 and DMOV is never
reset.

On the problemic controller, the first axis' MSTA field is 0xa0a when
idling. 
According to the motor doc, it means "PROBLEM: driver stopped polling".
(Which is
not true, because it can be moved and position is reported correctly and
even DMOV field.) 
Would this false status report affect the other axis?

How do I know why the first axis is reported as "PROBLEM", while the
polling is correct. 
Where should I put diagnostic messages?

Thanks.
