Tks Mike for fast answer,
I just plug in the drive to computer ( and a motor to the drive ), click Drive / AutoDetect it work
then i expected to run "autotune" ( in case of failure, a wizard may have request me to input "motor details" )
As you suggest : Not that simple.
So i try to reset the drive to factory default => Nop
I set A017 to 1 => Nop
i tought my motor was gone, so i check
Trick was to un-install CX-DRIVE from French and re-install in English
so i can read full messages inside Popup box.
like please set A001 to 3 and A002 to 3
Now the drive and the motor talk start and stop like expected
Motor OK, Drive OK, Cx-drive OK
once hardware is good, real play can start
