The 6SL3520-0XK04-0AA0 delivers the same 4 kW power platform as the top-tier G120X wall-mounted variant in a standard I/O configuration, making it a cost-effective choice for infrastructure applications where the full I/O complement of the -0AF0 variant is not required. The same IP65/66 sealed enclosure, C2 EMC filter, and -30 to +40°C operating range ensure reliability in wet, dusty, and outdoor installations without a control cabinet.

When should you choose the -0AA0 over the -0AF0 variant?

Both variants share identical power electronics, enclosure, and environmental ratings. The -0AA0 is positioned for applications that need the G120X wall-mounted platform but do not require the maximum I/O count or the full communication interface set of the -0AF0. If your application involves a straightforward pump or fan with basic start/stop and speed reference signals, the -0AA0 provides the same drive performance at a lower cost. Consult the official ordering catalog for the exact I/O and fieldbus configuration of each suffix variant.

What overload performance does this drive offer for pump and fan duty?

The drive supports a three-tier overload profile tailored to variable-torque loads: 200% for 3 seconds to ride through momentary blockages or startup surges, 150% for 57 seconds for short-term demand peaks, and 87% for 240 seconds — equivalent to low-noise continuous operation at slightly reduced output. This profile matches the duty cycles typical of centrifugal pumps and axial fans.

How does the drive integrate with SIMATIC control systems?

The G120X connects to SIMATIC PLCs through the TIA Portal engineering framework using predefined converter macros and preconfigured function blocks, eliminating manual parameter mapping. Commissioning options include the IOP-2 operator panel, a web server module for wireless access, and SD memory card cloning for series deployment. Motor cable runs up to 150 metres are supported without an additional output reactor.

Frequently Asked Questions

Does the -0AA0 variant support the same motor cable length as the -0AF0?

Yes. All 0XK0-series variants support motor cable lengths up to 150 metres without an additional output reactor, regardless of suffix configuration. The suffix affects I/O and communication features, not the power stage or output filtering.

Can this drive operate with non-Siemens motors?

Yes. The G120X can drive any standard 3-phase induction motor within its 4 kW / 20.4 A rating and is also optimized for Siemens synchronous reluctance motors for IE4/IE5 efficiency targets.
