The 6SL3230-3YE22-1UP0 is a 5.5 kW SINAMICS G120X general-purpose converter in the FSB frame, unfiltered, with DC link terminals. Rated at 18 A LO for pump and fan duty, the DC terminals provide access to the DC link for connecting a du/dt filter — reducing motor winding stress on long cable runs. It carries the P-suffix standard catalog ordering designation.

Why Choose the DC Terminals Variant?

The 1xxx suffix variants add DC link terminals compared to the 0xxx variants at the same 5.5 kW / 18 A LO rating. When the motor cable length exceeds the drive's unfiltered limit, a du/dt filter connected at the DC link reduces voltage stress on the motor insulation — extending motor life without requiring a full sine-wave filter at the output. The 0UP0 (no DC terminals) suits shorter cable runs where the drive's internal protections are sufficient. At 5.5 kW in the FSB frame, the 1UP0 pairs this capability with unfiltered EMC — choose it when DC link access is needed and system-level EMC filtering is already in place.

G120X Platform — 5.5 kW FSB

The FSB frame (100 × 275 × 209 mm, IP20) houses the G120X platform with 3C3 coating, PROFINET/EtherNet/IP/USS/Modbus RTU/BACnet MS/TP fieldbus, V/f square-law and V/f ECO control, and integrated STO via F-DI or PROFIsafe. The 110%/60s LO overload matches centrifugal pump and fan duty cycles.
