400 kW overload profile — what it means for pump and fan duty
The 6SL3220-3YE60-0CP0: The headline rating is 400 kW, but the overload envelope is what decides whether this drive holds a centrifugal pump through a blocked-discharge start or a cooling tower fan through a gust load. The SINAMICS G120X delivers 135 % rated current for 3 seconds, 110 % for 60 seconds, and 100 % for 240 seconds — that three-tier profile matches the starting and transient demands of HVAC/water/wastewater rotating equipment, where the motor draws locked-rotor current for a few seconds then settles to running load. A drive rated only for continuous kW without the overload headroom would trip on the inrush.
Active production — no lifecycle risk for the BOM line
This order code carries an active lifecycle status; the product stage is listed as mature, meaning it is in steady production with no announced end-of-life. The product class is C — manufactured to order, not a stocked shelf item — so lead time follows the production schedule rather than warehouse availability.
Fieldbus interface and I/O — PROFIBUS DP, no expansion module
The integrated fieldbus is PROFIBUS DP, which means this variant connects directly to a PROFIBUS DP master without an additional communication module. There is no IO expansion board included — the drive ships with the Intelligent Operator Panel (IOP) for local parameter access and commissioning. If the application requires additional digital or analog I/O beyond what the base unit provides, an expansion module would need to be ordered separately.
RFI suppression, ambient limits, and enclosure
The built-in RFI suppression filter is rated for category C3 (industrial environment, not residential), covering the 3AC 380-480 V range at +10/-20 % tolerance, 47-63 Hz.
