Hi @ReneGalindo, welcome to the B&R Community! As Valerio asked, please confirm the exact model number of the the new ACOPOSmulti SafeMOTION drive that was replaced.
If the new drive has the same model number as the old one (8BVI0330HWSS.000**-1**), then I would double-check the node number that is configured in the project compared to what is set on the ACOPOSmulti.
If the new drive is a 8BVI0330HWSS.000**-4**, then you need to take a few things into account:
- mapp Motion / ACP10ARNC0 version 5.24.1 or higher
- If the AS project is using mapp Safety, it must use version 5.24.0 or higher
- If the AS project is using Legacy Safety, it must use version 1.10
Please find additional information about replacing an ACOPOSmulti SafeMOTION -1 with a -4 in this Community post: Upgrading from 8BVIxxx-1 and 8BVIxxx-3 SafeMOTION ACOPOSmulti modules to 8BVIxxx-4 modules
