What it is and where it fits
The Siemens 6SL3055-0AA00-6AA0 is a SINAMICS DRIVE-CLiQ Hub Module, cabinet-mount DMC20 — no DRIVE-CLiQ cable included. It sits in a panel or enclosure, collecting DRIVE-CLiQ lines from drives and feeding them back to the control unit. This is the central star-point for the fiber-optic ring in a multi-axis SINAMICS setup.
