315 kW HVAC/water drive — overload and fieldbus
The 6SL3220-3YE56-0CF0: This Siemens SINAMICS G120X is a 315 kW infrastructure converter built for HVAC, water, and wastewater applications. It delivers 135% overload for 3 seconds or 110% for 60 seconds, with 100% current for 240 seconds — the overload profiles match pump and fan duty cycles where short-duration torque spikes occur during startup or blockage clearing. The drive operates from 3-phase 380-480 VAC (+10%/-20%) at 47-63 Hz and includes a built-in EMC filter for Category C3 environments.
Fieldbus and operator interface
Integrated PROFINET-PN and EtherNet/IP ports let the drive connect directly to a PLC or building management system without an external gateway. The intelligent operator panel (IOP) provides local parameter access, diagnostics, and commissioning wizards — useful for site startup or troubleshooting without a laptop. No IO expansion module is included in this order code. If additional digital/analog I/O is needed for local feedback or interlocking, the G120X platform supports plug-in IO expansion modules — check the BOM for the specific I/O count required.
