The 6SL3120-2UE21-0AD0 is a SINAMICS S220 Double Motor Module in the Booksize D format, taking a 600 V DC link input and delivering 400 V three-phase AC at 9 A per axis. That dual-channel output drives two independent motors — typically servos or induction spindles — from a single module, saving panel width compared to two single-axis units.
Integration notes
Booksize D width fits the SINAMICS S220 backplane system; the module slides into the mounting frame and connects to the DC link busbars. The 9 A per-channel rating covers small to mid-range servo axes on conveyors, packaging machines, or handling cells.
