The SINAMICS G115D 6SL3520-0XE45-5AB0 is the 5.5 kW wall-mounted distributed frequency converter in FSC frame with PROFINET communication — the Ethernet-based counterpart to the AS-Interface AF0 variant on the same XE45 hardware platform. Part of the SINAMICS G115D series, it delivers 13.2 A rated output current with 200% overload for 3 seconds, driving IE3 asynchronous or IE4 synchronous reluctance motors via direct SIMOGEAR 2KJ8 geared motor mounting. The integrated 2-port PROFINET switch with PROFIsafe tunnels STO over the same Ethernet cable — no separate safety relay, no dedicated hardwiring, no additional cabinet space.

What sets the XE45 PROFINET variant apart at 5.5 kW?

The XE45 catalog designation delivers PROFINET at the 5.5 kW FSC power tier — a key mid-range rating for merge conveyor zones, accumulating conveyors, and palletizing infeeds where multiple drives must coordinate speed and position. The integrated 2-port switch enables daisy-chain topology: the drive connects to its upstream and downstream neighbors, eliminating dedicated Ethernet switch ports at each conveyor zone. For mixed-vendor plants, the drive simultaneously accepts EtherNet/IP connections alongside PROFINET communication. STO via PROFIsafe is configured in TIA Portal and executed over the existing network — no dedicated safety wiring.

What motors and gearboxes can it drive?

The 6SL3520-0XE45-5AB0 is optimized for direct mounting to SIMOGEAR 2KJ8 geared motors in IE3 or IE4 efficiency classes. Integrated 400 V AC brake control eliminates external brake contactors and rectifiers. Encoderless vector control delivers speed regulation without a feedback device, supporting both V/f control for basic conveyor sections and sensorless vector control for precise ramp-controlled acceleration. The Q8/0 motor connector and M12 signal interfaces enable quick commissioning with pre-assembled Siemens cables.

Frequently Asked Questions

What is the difference between XE45 and XH25 for the same 5.5 kW rating?

XE45 and XH25 are catalog designations for the same 5.5 kW FSC hardware — mechanically and electrically identical (425 × 240 × 169 mm, 13.2 A rated, integrated fan). Both support AB0 (PROFINET) and AF0 (AS-Interface) variants. The XE prefix identifies the XE4x catalog series, XH identifies the XH2x catalog series — the drives are functionally interchangeable, differentiated only by commercial catalog organization.

Can this drive run on an existing AS-Interface network?

No — the AB0 variant communicates exclusively via PROFINET (and EtherNet/IP). For AS-Interface integration, choose the AF0 variant (e.g., 6SL3520-0XE45-5AF0) which connects to AS-i masters over the yellow AS-i cable. For hardwired control, the AA0 I/O Control variant provides discrete I/O terminals.

Does this drive support STO without PROFINET?

Yes — STO is also available via the fail-safe digital input (F-DI), independent of PROFINET communication. The F-DI accepts a 24 V DC safety signal from an external safety relay or emergency stop circuit, providing an alternative safety path for EtherNet/IP applications requiring SIL 2/PL d functional safety.
