The 6SL3520-1XK00-7AF0 extends PROFINET connectivity down to the 0.75 kW tier of the 1XK series. At 2.2 A rated output in the FSA frame, this drive powers the most numerous stations on a decentralized conveyor or packaging line — roller drives, belt segments, diverter arms — where the mechanical power requirement is low but the control requirement is not. PROFINET at this power level means every station, even the smallest, reports actual speed, torque, and fault status to the line controller on the same cyclic telegram as the main drives.

The value of network uniformity

When every drive on a line uses PROFINET — from the 0.75 kW roller segment to the 7.5 kW main conveyor — the commissioning engineer works with one tool (TIA Portal), one device description language (GSDML), and one diagnostic framework. There is no mix of hardwired stations requiring separate multimeter checks and networked stations visible from the engineering workstation. Specifying AF0 across the entire power range eliminates this split, and the 0.75 kW AF0 variant makes that uniformity affordable at the smallest drive sizes.
