315 kW at 135% overload — motor sizing for pump and fan loads
The 6SL3220-3YE56-1CB0: This SINAMICS G120X drive delivers 315 kW rated power with a 135% overload for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds — the overload profile that matches centrifugal pump and fan starting torque curves without oversizing the drive for the transient. The 380-480 VAC input range with +10/-20% tolerance handles the sag you see on a weak utility feed during a neighbouring motor start; the RFI suppression filter for category C3 keeps conducted emissions within the limits for industrial power networks without an external filter.
Fieldbus integration — MODBUS RTU and BACnet MS/TP on board
The drive ships with MODBUS RTU, BACnet MS/TP, and USS protocols integrated — no external gateway card needed for a BAS or SCADA tie-in. The IO expansion and intelligent operator panel are included in the base unit, so the BOM line for a pump skid or AHU drive cabinet stays at one order code. Size FSH enclosure at IP20 / UL open type means it mounts inside a panel with forced ventilation; the 800 x 1870 x 600 mm packaging dimensions give the panel builder the gland-plate and bus-bar clearance to plan around.
RoHS compliant since 11 March 2020; the REACH Article 33 declaration notes lead (CAS 7439-92-1) above 0.1% w/w — standard for power-semiconductor solder joints, but the compliance documentation covers the EU regulatory gate for equipment destined for the European market.
