With the arrival of XE03-0AB0, the G115D XE03 at 3kW fanless FSB is now complete across all three communication interfaces. SINAMICS G115D XE03-0AB0 pairs 3kW fanless FSB hardware with PROFINET — integrating drive control, functional safety, and network redundancy into one Ethernet cable. This XE0x catalog path runs the same 7.12 kg fanless FSB platform as XE43, XH23, XN03, XM03, 1XA03, and 1XA23 — seven parallel catalog codes for the highest fanless G115D power rating.

Why choose PROFINET on a fanless 3kW G115D?

At 3kW — the highest fanless rating in the G115D lineup — this drive already handles the heaviest conveyor zones without a cooling fan. Adding PROFINET turns it into a safety-integrated motion node. The built-in 2-port switch supports daisy-chain line topology and MRP ring redundancy. PROFIsafe runs STO (Safe Torque Off) over the same Ethernet cable — no separate safety wiring. For a palletizer infeed, a turntable, or a cross-belt sorter discharge, this is the highest-power G115D you can deploy in a washdown zone without adding a fan to the maintenance equation.

What communication interfaces does XE03 support?

XE03 now carries all three G115D communication variants — AA0 (I/O Control via digital/analog signals), AF0 (AS-Interface two-wire fieldbus), and AB0 (PROFINET with PROFIsafe and EtherNet/IP support). The XE0x sub-series at 3kW mirrors the comm flexibility of 1XA23 and XH23. For applications needing only basic start/stop and speed reference, XE03-0AA0 eliminates fieldbus complexity entirely. For AS-Interface fieldbus integration, XE03-0AF0 connects over the yellow flat cable. XE03-0AB0 is the choice when PROFINET networking, functional safety over PROFIsafe, or MRP ring redundancy are required.

How does XE03 compare to XE43 and 1XA23?

XE03 (XE0x sub-series), XE43 (XE4x sub-series), and 1XA23 (1XA2x sub-series) are the same 3kW fanless FSB hardware — identical 7.12 kg enclosure, identical 7.7A rated / 15.4A overload output, identical natural-convection cooling with no fan to maintain. The difference is purely the catalog digit in the part number. XE0x and XE4x coexist within the XE catalog family just as 1XA0x and 1XA2x coexist within 1XA — parallel commercial catalog codes, not different drives. Procurement can cross-reference any of these codes when availability is constrained. All three carry PROFINET AB0 variants.

Frequently Asked Questions

Does this drive need a cooling fan?

No. XE03 is fanless — the 7.12 kg FSB enclosure provides sufficient thermal mass for natural-convection cooling at 3kW. This is the highest fanless rating in the entire G115D range. From 4kW upward, an integrated fan adds 35mm to the enclosure depth.

Can I daisy-chain multiple XE03-0AB0 drives?

Yes. The integrated 2-port PROFINET switch enables line topology without external switches. For ring redundancy, configure MRP (Media Redundancy Protocol) — if one cable segment fails, the ring heals in under 200ms.

Which cable is required for PROFINET connection?

Standard industrial Ethernet cable (CAT5e or better, 4-wire shielded). The drive has two RJ45 ports on the front face — accessible without opening the IP65 enclosure.
