355 kW duty cycle — what the overload ratings mean for pump/fan sizing
The 6SL3220-2YE58-1CP0: This SINAMICS G120X drive is rated 355 kW with a duty cycle that mirrors HVAC and water/wastewater loads: 135 % for 3 s (starting inertia), 110 % for 60 s (system recovery), and 100 % for 240 s (steady-state). The 135 % short-term peak handles the locked-rotor inrush of a centrifugal pump or the fan breakaway torque without oversizing the drive frame. The RFI suppression filter is built in for category C3 (industrial environment), so no external filter is needed for EN 61800-3 compliance in a typical electrical room. Input range is 380-480 V +10/-20 %, 47-63 Hz — covers standard 400 V and 480 V grids without a transformer tap.
Integration — IP20, size FSH, and the PROFIBUS DP interface
The FSH frame size determines the mounting footprint and gland-plate layout; the packaging dimensions (800 x 1870 x 600 mm) give a sense of the crate size for logistics planning. PROFIBUS DP is integrated on the control board — no separate communication module needed. The Basic Operator Panel (BOP) is included for local parameter access and commissioning.
