At 0.75 kW (2.2 A rated, 4.4 A overload), the 6SL3520-1XE40-7AF0 is the entry-level G115D — the smallest, lightest, and most economical drive in the series. In the 380 × 156 × 129 mm FSA frame with just 43.1 W power loss, it runs entirely on natural convection — no fan, no moving parts, zero fan-related maintenance for the life of the drive.

What applications does the entry-level 0.75 kW G115D serve?

The 0.75 kW rating covers the vast majority of individual zone-roller conveyor sections in e-commerce and parcel distribution centers — short belt segments, diverter arms, and single-zone accumulation beds. A single distribution center may deploy several hundred 0.75 kW drives, each controlling one zone independently. The G115D's wall-mounted distributed architecture eliminates the central VFD cabinet for these zones: each drive mounts at its motor, connecting back to the SIMATIC controller via PROFINET. The 1XE configuration means even the entry-level drive carries the same IP66 gland sealing and C2 RFI filter as a 7.5 kW unit — no feature downgrade at the low end of the power range.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. The 350 Ω integrated braking resistor (10 W continuous) supports dynamic braking. Integrated PROFINET and Ethernet IP interfaces connect directly to SIMATIC controllers. The built-in C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits for industrial environments.
