The first step into the FSB frame — 2.2 kW, 5.9 A output, 96 W power loss. Still cooled by natural convection; the larger FSB heat sink (7.12 kg) has enough surface area to keep semiconductor temperatures in check without forced air.

AB0 suffix: standard I/O with brake control. This is the workhorse configuration for mid-size conveyor sections — enough power for a 50-meter roller bed, integrated brake output for incline sections, and hardwired I/O for the speed reference from a central controller.

At 96 W loss, this drive runs cooler than the 1.5 kW FSA (67 W) on a per-watt basis thanks to the larger FSB heat sink. The thermal headroom also leaves room for higher ambient temperatures without derating.
