The 6SL3520-1XH21-5AF0 is the PROFINET-equipped variant at the top of the G115D FSA power range: 1.5 kW, 8.2 A, fanless. It delivers the highest power available in the compact FSA frame while adding PROFIdrive communication — the drive appears as a standard PROFINET IO device on the TIA Portal network alongside every other drive, HMI, and I/O block in the system.

1.5 kW with PROFINET — maximum FSA, fully networked

This variant combines two ceilings: the highest FSA power rating and the AF0 fieldbus interface. For a conveyor system architect, it means the most powerful small-frame drive does not sit outside the network — it reports motor current, DC-link voltage, and fault status to the controller in real time, just like the 7.5 kW FSC drive at the other end of the power range. When the line stops, the SCADA screen shows exactly which drive tripped and why, from the largest to the smallest.

Fanless and networked — no trade-off

The PROFINET interface adds no heat load that would push the FSA frame beyond its fanless thermal envelope. The drive still cools passively at approximately 250 mA from the 24 V DC rail — identical to its hardwired-I/O sibling. The only difference is an RJ45 port next to the power terminals. For conveyor OEMs who want full network visibility without adding fan maintenance to the service schedule, this is the 1.5 kW drive that delivers both.
