315 kW at 135% overload — the motor-sizing number
The 6SL3220-2YE56-0CP0 is a SINAMICS G120X infrastructure converter rated 315 kW continuous output from a 380-480 V 3-phase supply. The 135% overload for 3 seconds (110% for 60 s, 100% for 240 s) means this drive handles pump start-up inrush and short-duration load spikes without tripping — a common requirement in HVAC and water/wastewater applications where the motor sees variable torque profiles. The drive belongs to the SINAMICS G120X family, purpose-built for HVAC, water, and wastewater infrastructure. The IP20 / UL open type enclosure means it mounts inside a panel or cabinet — not a standalone outdoor unit.
PROFIBUS DP and EMC filter C3 — what they mean for integration
Integrated PROFIBUS DP fieldbus is the control interface — no separate communication module needed. The drive ships with a Basic Operator Panel (BOP) for local parameter access, but no I/O expansion slot is fitted. For additional I/O or a different fieldbus, you'd look at the G120X variants with the optional I/O module slot. The built-in radio interference suppression filter is category C3, which covers industrial second-environment installations (mains supply not in a residential building). For first-environment (residential) compliance, an external filter would be required. The input voltage range is 380-480 V 3-phase +10%/-20%, 47-63 Hz.
