560 kW at 690 V — overload profile for pump and fan loads
The 6SL3220-3YH66-0CB0: Rated power 560 kW with a 135% overload for 3 seconds or 110% for 60 seconds, and 100% continuous for 240 seconds — this is the overload duty cycle typical for centrifugal pumps and fans where the starting torque is low but the inertia keeps the drive in the overload region during ramp-up. Input voltage range 3AC 500-690 V +10/-20% at 47-63 Hz, so it covers 525 V, 600 V, and 690 V nominal grids without a transformer — common in North American 600 V and European 690 V industrial distribution.
Fieldbus integration for building automation
Integrated MODBUS RTU and BACnet MS/TP on the same RS-485 port — no external gateway needed for BMS integration. The BACnet MS/TP profile maps the drive parameters as BACnet objects, so the building controller sees speed, current, and fault codes directly. The Intelligent Operator Panel (IOP) is included — it provides a plain-text display for commissioning and diagnostics without a laptop. No IO expansion module is fitted as standard; the base unit has the I/O for start/stop, speed reference, and fault relay.
Installation constraints — IP20, size FSJ, ambient limits
Degree of protection IP20 / UL open type — the drive must be installed inside a cabinet with a minimum IP54 enclosure to keep dust and moisture off the power terminals. Size FSJ is the largest frame in the G120X family; the packaging dimensions of 1200 x 1857 x 800 mm give a sense of the crate size for logistics planning. Ambient temperature range 0 to +45 °C — above 45 °C the output current must be derated per the SINAMICS G120X manual. The drive is rated for 100% continuous current at 45 °C ambient; at 50 °C expect a derating of roughly 2-3% per degree.
Export control classification AL:N / ECCN:EAR99H — no special export license required for most destinations, but the REACH Article 33 declaration notes lead content above 0.1% w/w in certain components, which may require downstream notification in EU markets.
