At 7.5 kW (19.0 A rated, 38 A overload), the 6SL3520-1XE07-5AA0 is the topology anchor of a G115D conveyor network — the main drive that feeds, synchronizes, and coordinates dozens of downstream zones. In a typical distribution-center layout, one 7.5 kW drive powers the main trunk conveyor, branching into 4 kW incline sections and 0.75–2.2 kW zone rollers — all on the same PROFINET segment, all programmed from the same TIA Portal project.

How does the 7.5 kW G115D act as the system-level drive in a multi-zone topology?

The main trunk conveyor sets the pace for every downstream zone. The 7.5 kW G115D runs in sensorless vector control mode, maintaining the master speed reference that downstream drives follow via PROFINET telegrams. If the trunk conveyor's load changes — a pallet enters or exits — the vector control compensates for slip and holds the speed setpoint, preventing cascading speed variations through the downstream zones. The FSC frame's unified 410 × 168 mm mounting pattern means the 7.5 kW drive bolts to the same machine-frame drilling as a 2.2 kW FSB — the mechanical design does not fork at high power. For the controls engineer, one macro, one telegram profile, and one diagnostic interface cover every drive from the 7.5 kW trunk to the 0.37 kW exit zone.

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. Sensorless vector control maintains speed setpoint within ±0.5% under varying load. 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.
