The 6SL3520-1XH61-5AF0 is the PROFINET variant of the G115D 1.5 kW FSA drive under the 1XH61 sub-code. At 8.2 A, it delivers the highest power available in the compact FSA frame with full PROFIdrive communication — the drive appears as a standard PROFINET IO device on the TIA Portal network.

1XH61 — the 1.5 kW sub-code generation

The 1XH61 sub-code identifies this hardware revision of the 1.5 kW FSA G115D. Like the 1XH21 (also 1.5 kW FSA), it uses the 380 mm FSA housing with natural convection cooling — no fan, approximately 250 mA from the 24 V DC rail, silent operation. The sub-code difference reflects Siemens' internal hardware revision tracking; for the installer and end user, the mounting dimensions, terminal layout, and commissioning workflow are unchanged.

PROFINET at the FSA ceiling

At 1.5 kW, this is the most powerful FSA drive with PROFINET. The AF0 interface carries speed setpoint, actual speed, motor current, and fault diagnostics to the PLC over a single RJ45 connection — no separate analog signal wiring. For conveyor OEMs who want every drive on the line, from the smallest FSA to the largest FSC, visible on the same TIA Portal project tree, this variant delivers networked control without leaving the fanless, maintenance-free FSA frame.
