The 6SL3520-0XH65-5AB0 delivers 5.5 kW at 11.8 A in the FSC frame with AB0 I/O configuration — the mid-power option in the actively cooled tier of the SINAMICS G115D family. It occupies the sweet spot between the 4 kW FSB (the top of the passively cooled range) and the 7.5 kW FSC (the maximum G115D power rating). For medium-duty conveyor sections — merge tables, transfer carts, moderate-incline belts, accumulation zones with moderate product weight — the 5.5 kW provides the right current reserve without the cost of the 7.5 kW model.

How does the G115D integrate into a TIA Portal automation project?

The G115D appears in TIA Portal as a PROFINET device with its own device name and IP address. Commissioning follows the standard SINAMICS workflow: the drive is discovered on the network, the motor data is read from the electronically identifiable SIMOGEAR gearbox (or entered manually for third-party motors), and the application parameters — ramp times, speed setpoints, control mode — are configured through the SINAMICS Startdrive interface integrated into TIA Portal. The drive supports both V/f and sensorless vector control; vector mode provides better low-speed torque regulation for conveyor breakaway conditions. Once commissioned, the parameter set can be saved and cloned to other G115D units on the same line via the TIA Portal project, reducing repetitive setup work for multi-section conveyor installations.

Frequently Asked Questions

What distinguishes the AB0 suffix from AA0 and AF0 on the 5.5 kW model?

The three suffix codes designate different I/O interface configurations — the specific set of digital inputs, outputs, and communication connectors. Core electrical parameters (5.5 kW, 11.8 A, 380–480 V, 0–550 Hz), mechanical dimensions (FSC: 425 × 240 × 169 mm), integrated brake chopper, and safety functions are identical. Consult the G115D operating manual for the terminal assignment of each suffix before selecting one for a specific installation.

Does the 5.5 kW FSC require a separate 24 V DC power supply?

The G115D control electronics can be powered either from the internal DC link (derived from the 380–480 V mains input) or from an external 24 V DC supply. Using an external 24 V supply keeps the control electronics and PROFINET communication alive even when the mains power is disconnected — useful for commissioning, diagnostics, and maintaining network topology visibility during maintenance shutdowns. If the application does not require control power during mains-off conditions, the internal supply is sufficient and no external 24 V wiring is needed.
