The 6SL3520-0XH65-5AA0 is the 5.5 kW SINAMICS G115D with AA0 standard I/O — the entry-level FSC-frame distributed drive for medium-to-heavy conveyor sections. At 11.8 A rated output, it bridges the gap between the passively cooled FSB and the full-power 7.5 kW FSC. The AA0 configuration provides the standard I/O interface for basic conveyor control: digital inputs for start/stop and direction, digital outputs for status indication, and PROFINET/EtherNet/IP via M12 for networked automation.

What are the installation requirements for a 5.5 kW G115D on a conveyor line?

The G115D mounts directly on the machine frame near the motor — no control cabinet is required for the drive itself. The installation needs: (1) a 3AC 380–480 V mains feeder with appropriate branch-circuit protection (circuit breaker or fused disconnect) sized for the 5.5 kW load; (2) a 24 V DC supply if control power is to be maintained during mains-off conditions; (3) a PROFINET or EtherNet/IP network drop via M12 connector; (4) the motor cable (≤15 m at 4 kHz); and (5) an external braking resistor if dynamic braking is required. The FSC enclosure is IP65 / IP66 / UL Type 4X, so it can be mounted in washdown areas and unheated logistics spaces (−30 °C to +40 °C operating range, derated above 40 °C). The integrated fan is thermostatically controlled and requires no ducting or external airflow management.

Frequently Asked Questions

How do the AA0, AB0, and AF0 suffixes differ on the 5.5 kW model?

The suffix codes designate the I/O interface configuration. All three share identical core drive specifications: 5.5 kW, 11.8 A, 380–480 V, 0–550 Hz, FSC frame, integrated brake chopper, STO, and PROFINET/EtherNet/IP support. Select the suffix based on the field-wiring requirements of the installation, using the G115D operating manual to confirm terminal assignments.

Can the 5.5 kW G115D operate in sensorless vector control mode?

Yes. The G115D supports sensorless vector control (SLVC) in addition to V/f and V/f ECO modes. SLVC provides better low-speed torque accuracy and tighter speed regulation than V/f — useful for conveyor applications where breakaway torque is critical or where speed consistency between adjacent sections is required to prevent product bunching. The drive calculates the motor flux and torque from measured current and voltage without an encoder, making it suitable for standard conveyor motors where adding a feedback device would be impractical.
