The 6SL3520-0XL01-5AF0 is the full-featured I/O variant at 1.5 kW — the entry-level power rating in the FSB-frame G115D series. Despite its modest 8.2 A output at 480 V 3-phase, it carries the complete on-board digital and analog I/O set, making it the right choice for light conveyor drives that need localized sensor and actuator wiring without remote I/O blocks. The 425 × 240 × 134 mm IP65/66 enclosure, C2 EMC filter, PROFINET/EtherNet/IP, and STO safety are all standard.

When does a 1.5 kW conveyor need full-featured I/O?

The combination of low motor power with full I/O is not a contradiction — it serves applications where the mechanical load is light but the control requirements are sophisticated. Examples include a precision metering conveyor in a pharmaceutical filling line with analog belt speed feedback, a cleanroom transport system where the drive reads local humidity and particle-count sensors, or a small indexing table where the drive directly controls a pneumatic clamp and reads a part-present sensor. In these cases the 1.5 kW motor is correctly sized for the load, while the full I/O complement handles the process instrumentation that happens to be co-located with the drive.

How does the 1.5 kW FSB variant compare to smaller FSA-frame G115D drives?

The FSB frame (425 × 240 mm) is wider and taller than the FSA frame (approximately 360 × 180 mm) used for the smallest G115D drives. The FSB variant offers higher power density — up to 4 kW in the same footprint — and the same connector layout. For a 1.5 kW application, choosing the FSB variant means the drive can be upsized to 2.2 kW, 3 kW, or 4 kW without mechanical modification, using the same mounting holes and connector positions. This is an advantage when future conveyor upgrades are anticipated.

Frequently Asked Questions

What is the minimum motor size the 1.5 kW G115D can drive?

The G115D can drive motors smaller than its rated output — there is no minimum motor size restriction. The drive's sensorless vector control adapts to the connected motor parameters, providing stable control down to no-load conditions. This is common in test and development setups where a 1.5 kW drive runs a small bench motor before deployment.

Can the 1.5 kW variant run a 2.2 kW motor temporarily?

The G115D's 200% overload capability for 3 seconds and 150% for 57 seconds means it can temporarily supply current beyond its 8.2 A continuous rating — roughly 16.4 A peak. A 2.2 kW motor's full-load current of 11.8 A is within this short-term envelope, but continuous operation above the drive's 8.2 A rating would trigger thermal derating. For sustained 2.2 kW operation, the correctly sized drive should be used.
