The 6SL3520-1XK01-1AB0 pairs the 1/3-phase wide-voltage input with an integrated braking chopper at 1.1 kW. The AB0 suffix equips the FSA drive with an internal braking resistor that dissipates regenerative energy from motor deceleration directly inside the IP65 enclosure — no external resistor enclosure, no additional wiring penetrations, no compromise to the sealed drive concept.

The 1.1 kW sweet spot for cyclic loads

A 1.1 kW distributed drive frequently powers indexing conveyors, lift-and-locate stations, and pick-and-place gantries — applications where every cycle involves acceleration, constant speed, and a hard stop. Each stop pushes energy back into the DC link. Without a braking chopper, the drive extends the deceleration ramp to stay below the overvoltage threshold, adding hundreds of milliseconds to every cycle. Over a million cycles per year, those milliseconds become hours of lost throughput. The AB0 variant lets the drive decelerate at the motor's mechanical limit — the braking resistor handles the energy, the cycle time stays tight, and the IP65 enclosure stays closed.
