The 2.2 kW step is where the G115D leaves the compact FSA frames and enters the FSB range: 5.9 A continuous, 11.8 A for 3 s at 200% overload, still cooled by natural convection in a 425x180x134 mm housing with nothing to maintain. On the machine frame, IP65/66, it is also the first step where a networked drive earns its place - one drive that moves a section and reports on it to the SIMATIC controller.

When does a conveyor section outgrow the FSA drives?

The FSA frames end at 1.5 kW and 4.1 A continuous. A section that keeps stalling on starts, or gains a heavier transfer, crosses that line with two options: move into the control cabinet, or step up within the wall-mounted range. The 2.2 kW step is the smaller jump - 5.9 A continuous, 11.8 A for 3 s at 200% overload, roughly 45 percent more current than the largest FSA - and it stays out of the cabinet, fanless, in the 425x180x134 mm FSB housing. No fan filter to clean, no fan bearing to schedule, and the integrated 175 ohm braking resistor (10 W continuous, 100 W peak) absorbs the stop energy of short deceleration ramps.

What does PROFINET change on a 2.2 kW section?

Terminal control tells you nothing about how the drive is running. With PROFINET, this section reports speed, current and fault states to the controller over the same hybrid cable that feeds its power - two M12 D-coded ports allow a daisy chain along the machine, and closing the ends turns the line into a ring where one cut cable stops nothing downstream. PROFIsafe shares the same wires, so the safety stop travels with the data and no separate safety cable is pulled. TIA Portal macros and predefined function blocks map the drive into the controller without hand-writing telegrams. Sections that never join a network take the AB0 or AA0 variant of this same 2.2 kW fanless hardware and run on plain terminals instead.
