The 6SL3520-1XK00-3AB0 is the smallest G115D available with an integrated braking chopper: 0.37 kW at 1.3 A, FSA frame, 1/3-phase wide-voltage input. At this power level, the drive typically handles a stop gate, a small diverter arm, or an eject station — single-motion actuators where every cycle ends with a hard mechanical stop and the motor decelerates against its load. The AB0 integrated braking resistor absorbs the regenerative energy from these frequent, short-duration deceleration events inside the sealed FSA enclosure.

Braking at the smallest scale

The 0.37 kW motor on a diverter arm may cycle three times per second in a high-speed sorting application. Each actuation stores kinetic energy in the arm's inertia that returns to the DC link on deceleration. Without a braking chopper, the drive extends the deceleration ramp to stay under the overvoltage threshold. With it, the drive stops the motor at its mechanical limit and the internal resistor dissipates the energy — the cycle time stays tight, and the station keeps pace with the line. The AB0 suffix brings this capability to the smallest and least expensive drive in the G115D catalog.
