RE: Difference between standalone and sectional(multi) Drive
Typically they are all in one enclosure and built as a complete unit.
A sectional drive is typically one larger rectifier that can be non- regenerative or regenerative (active or not) and this feeds a DC link that consists of multiple inverters that feed off this common DC link. Each inverter section are independently running motors that can be 1quadrant or 4 quadrant driven and sometimes have the ability to either take power from the DC link or return power to the DC link. If taking, this comes from the rectifier or other inverters that could be regenerating.
Common applications for the latter are paper processes, steel rolling processes, printing machines etc.
