The 6SL3520-1XD02-2AF0 is the debut of 1XD02 — the 1XD D-connector SINAMICS G115D at 2.2 kW FSB fanless, the FSA-to-FSB transition power. This is the first 1XD code at the critical boundary where natural convection in the compact FSA frame (380 × 156 × 129 mm) becomes insufficient, requiring the move to the larger FSB fanless enclosure (425 × 180 × 134 mm, 7.12 kg). It delivers 5.9 A HO (11.8 A LO) with natural convection cooling. AF0 provides PROFINET IO with PROFIsafe, EtherNet/IP, and an integrated 2-port switch, designated for SIMATIC control systems. Operates at 380–480 V three-phase, compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

1XD family — the new complete picture

The D-connector is no longer FSA-only. 1XD now spans 0.37–4 kW across FSA and FSB — the same range as 1XC (C-connector) and approaching the breadth of 1XB (B-connector, 0.37–7.5 kW). The D-connector ecosystem is now viable for mixed-power machines where FSA and FSB drives share the same D-connector cabling infrastructure. 1XD02 parallels 0XD02 (structurally expected), 0XB02/0XB42 (B-connector), 0XC02/1XC02 (C-connector), and all other 2.2 kW FSB fanless codes.
