The 6SL3230-3YE14-0UP0 is the entry-level configuration of the 1.5 kW SINAMICS G120X — a general-purpose frequency converter for control cabinet mounting. The P-Suffix designates the basic I/O configuration: the essential digital and analog I/O needed for simple pump and fan control, without the additional communication or I/O expansion of the F and B variants. This drive is unfiltered (no integrated EMC filter) and has no DC terminals.

What does the P-Suffix basic I/O configuration include?

The P-Suffix variant provides the core I/O set for straightforward variable-speed applications: digital inputs for run/stop and preset speeds, analog input for 0–10 V or 4–20 mA speed reference, and a relay output for fault or running status. For a building services panel controlling a single pump or fan at fixed speed steps, this is all the I/O needed — no unused channels, no cost tied up in unneeded features. Commissioning is via the BOP-2 basic operator panel or the IOP-2 intelligent operator panel (both optional).

What applications suit the 1.5 kW unfiltered G120X?

At 1.5 kW with 4.8 A LO rated current (110% overload for 60 seconds), the FSA-frame G120X handles small pumps, ventilation fans, and cooling tower fans in building HVAC and light industrial water/wastewater applications. The unfiltered configuration is appropriate when an external EMC filter is already present in the cabinet or when the installation does not require conducted emissions compliance to C2. The wide supply voltage tolerance (380–480 V +10/-20%) accommodates real-world mains variation across global installation sites.
