Hi @PEMA ,
We don’t know if in your prj you are using legacy (ACP10) or mapp Motion for axis control, but ACOPOS 1090 is a little bit old and I guess you use legacy version,
so with SDM, there is a page axis information where you get more details (The Axis Information page can be opened using the URL **http://IP-address/sdm/*motion_axis.html**\*):
You can see for example if the Enable signal is high or low, Alarm…
===============================
I see, from the Academy, we have a free microlearning module for the System Diagnostic Manager (SDM) Release 2026 : Learning Content for End Users and Service Engineers: SDM
