The 6SL3520-1XE00-5AA0 completes the 1XE00-5 communication variant set — the new 1XE series at 0.55 kW FSA now carries all three G115D communication interfaces. It delivers 1.7 A HO (3.4 A LO) in the FSA compact frame (380 × 156 × 129 mm, ~4.7 kg) with natural convection cooling, designated for SIMATIC control systems. AA0 provides basic digital/analog terminal control — the simplest interface for a 0.55 kW standalone drive. Operates at 380–480 V three-phase, compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.
