The 6SL3520-0XL03-0AF0 is the full-featured I/O variant of the 3 kW SINAMICS G115D distributed drive — the top-tier configuration at this power rating. It provides the maximum on-board digital and analog I/O complement available in the G115D FSB series, enabling complex distributed control tasks without external remote I/O modules. All other specifications — 425 × 240 × 134 mm FSB frame, IP65/66 enclosure, Category C2 EMC filter, PROFINET and EtherNet/IP communication, and STO safety — are shared with the standard and basic variants.

What does the full-featured I/O variant offer that standard and basic do not?

The full-featured (-0AF0) variant includes the complete I/O channel set: additional digital inputs and outputs beyond the standard (-0AA0) tier, plus analog I/O channels for sensor interfaces that the standard and basic variants lack. This allows direct connection of analog sensors — such as tension monitors, temperature probes, or 4–20 mA position feedback devices — to the drive itself, eliminating the need for a separate analog input module on the conveyor segment. The digital I/O count is also higher than the standard variant, supporting more localized sensors and actuators per drive.

When does a conveyor application justify the full-featured I/O tier?

Choose the full-featured variant when the conveyor segment requires local analog sensing — belt tension monitoring, bearing temperature measurement, or continuous position feedback — that would otherwise demand a dedicated analog remote I/O station. It is also the right choice when the drive needs to control multiple local actuators (brakes, diverters, indicators) directly, without routing every signal back to a central PLC I/O rack. For a simple belt conveyor with only start/stop and speed reference over PROFINET, the basic or standard variant is more cost-effective.

Frequently Asked Questions

Does the full-featured variant support sensorless vector control?

Yes. Sensorless vector control is included across all G115D suffix variants. The full-featured variant adds the analog input channels to accept an external speed or position reference, but the core control algorithm — including low-speed torque regulation and smooth acceleration ramps — is identical to the standard and basic models.

Can the G115D drive a 3 kW SIMOGEAR geared motor directly?

Yes. The G115D is designed for direct wall-mounted pairing with SIMOGEAR 2KJ8 geared motors up to IE2 efficiency class. The 3 kW variant outputs 15.4 A at 480 V 3-phase with 200% overload for 3 seconds, covering the starting and peak torque requirements of conveyor belt acceleration under load.
