The 6SL3520-0XH67-5AA0 is the 7.5 kW SINAMICS G115D with AA0 standard I/O configuration — the highest-power distributed wall-mounted drive in the G115D family. At 17.1 A rated output in the FSC frame, it is purpose-built for the conveyor sections that define the throughput ceiling of a decentralized automation line: high-speed merge conveyors, incline sections carrying dense loads, pallet-handling transfers, and accumulation zones where the combined static load of stopped product can exceed 500 kg on a single driven section.

How should I pair the 7.5 kW G115D with a SIMOGEAR geared motor?

The G115D is mechanically designed for direct mounting on SIMOGEAR 2KJ8 geared motors with IE3 asynchronous or IE4 synchronous reluctance motors. At 7.5 kW, the motor frame size is typically a 132S or 132M — heavier than the smaller motors paired with FSA/FSB drives, which makes the direct-mount design especially valuable because it eliminates the need for a separate drive mounting bracket. The drive auto-adapts during TIA Portal commissioning by reading the electronically identifiable gearbox data. The recommended maximum motor cable length is 15 m at the default 4 kHz pulse frequency; longer cables require an output reactor or reduced pulse frequency to manage voltage-reflection stress on the motor windings.

What overload headroom does the 7.5 kW FSC provide for conveyor starting torque?

Conveyors draw their highest current during breakaway — the moment the belt must overcome static friction to start moving. The 7.5 kW FSC delivers 17.1 A continuously (LO) with 110% overload for 60 seconds, and can deliver up to 150% for 3 seconds in HO mode. This short-duration headroom covers the breakaway current spike without nuisance tripping. For conveyors that start fully loaded — common in accumulation zones — the HO rating provides the necessary margin. Note that the work.txt current value of 38 A for this model reflects the peak HO current, not the continuous LO rating; when sizing the drive against the motor nameplate, use the 17.1 A LO figure.

Frequently Asked Questions

How do the AA0, AB0, and AF0 suffixes differ on the 7.5 kW model?

The three suffix codes designate different I/O interface configurations. The 7.5 kW power rating, 17.1 A output, FSC dimensions, integrated brake chopper, STO, and PROFINET support are identical across all three. The choice is a field-wiring compatibility decision — confirm the specific terminal assignment for each suffix in the G115D operating manual before ordering.

Can the 7.5 kW G115D be used on an incline conveyor?

Yes — and this is one of the applications where the integrated brake chopper is essential. An incline conveyor moving product uphill generates regenerative energy on deceleration that must be dissipated to prevent a DC-link overvoltage trip. With a correctly sized external braking resistor (minimum 40 Ω for FSC), the G115D handles controlled stops on inclines up to the mechanical limit of the conveyor. For decline conveyors where the load drives the motor continuously (overhauling load), a drive with full line-regenerative capability would be required — the G115D brake chopper is designed for stopping, not continuous regeneration.
