The Siemens 6SL3520-1XA64-0AA0 is the standard AA0 variant of the SINAMICS G115D distributed drive at 4 kW (5 hp, 10.2 A) in the FSB fan-cooled frame — the lowest-power G115D requiring forced-air cooling. It delivers full PROFINET/EtherNet/IP fieldbus, STO SIL2 safety, and IP65/IP66 protection in the most economical 4 kW configuration. Ideal for standalone mid-power conveyor drives where the PLC manages all control and the operator panel and daisy-chain connectors of the AB0 and AF0 variants are not needed.

Frequently Asked Questions

How does the 4 kW AA0 differ from the 3 kW AA0?

The key difference is cooling: the 3 kW (7.7 A) is fanless FSB (134 mm deep), while the 4 kW (10.2 A) requires an integrated fan and a deeper FSB frame (169 mm). Both share the same width and height, and both use the AA0 standard fieldbus configuration. Choose based on motor power — there is no feature difference between the two AA0 variants.

Does the fan run continuously on the 4 kW model?

Yes. The integrated 24 V DC fan runs whenever the drive is powered. It is temperature-monitored — if the fan fails, the drive issues a PROFINET diagnostic alarm and will derate output current to protect the power stage if temperatures rise.
