55 kW VFD for pump and fan duty — active production, no obsolescence risk
The 6SL3220-3YC40-0UB0: The drive delivers 110% overload for 60 seconds and 100% continuous overload for 240 seconds — a duty profile matched to variable-torque loads such as centrifugal pumps, fans, and compressors where peak demand is brief and infrequent.
Fieldbus integration and operator interface
Integrated MODBUS RTU and BACnet MS/TP fieldbus are standard on this unit — no separate communication module is needed for building automation or SCADA integration. The Intelligent Operator Panel (IOP) is included, providing local parameter access, fault logging, and commissioning wizards without a laptop.
Mounting, environment, and compliance
Frame size FSF with IP20 / UL open type protection — the drive is designed for panel mounting in a clean, dry electrical room. Ambient temperature range is -20 to +45 °C without derating; painting class 3C2 provides moderate corrosion resistance for environments like water treatment or HVAC plant rooms. RoHS compliant since July 2006, and REACH Article 33 duty-to-inform documentation is available on request. Export control classification is AL: N / ECCN: N — no special license required for most destinations.
