Why is the simplest drive on the line also the cheapest to install?

Architecture cost is where distributed drives win or lose against a central cabinet. For a light section at 0.37 kW, the cabinet alternative means a long motor cable back to the panel, a slot in the enclosure, and cooling to spare — none of which serve the section. This -AB0 G115D bolts to the machine at IP65/66, connects through M12 plug-in connectors, and is controlled by hardwired digital I/O with Safe Torque Off via the fail-safe input. There is no network configuration to pay for and no cabinet slot to claim; the installed cost is the drive, the cable, and the mounting.

What does 0.37 kW cover when the section runs hard?

At the bottom of the G115D range the drive still carries 200% overload headroom: 1.3 A rated output, 2.6 A peak, so a light section that occasionally surges — a jam being cleared, a short accumulation burst — does not trip the drive. Matched to SIMOGEAR 2KJ8 geared motors up to 550 Hz output, the rating suits the small lanes and spurs that give the main line its flexibility. If the section later takes on a heavier load, the 0.55 kW step sits on the identical FSA footprint: same mounting, same cable, swap the unit.
