55 kW at 110% — overload capacity and input voltage range
The 6SL3220-3YC40-0UF0: Rated 55 kW continuous output with 110% overload capability for 60 seconds and 100% for 240 seconds — this is the standard heavy-duty rating for pump, fan, and compressor loads where intermittent torque spikes are expected. Input accepts 200-240 V 3-phase AC +10/-20% at 47-63 Hz, unfiltered. The unfiltered input means an external line reactor or EMC filter may be needed depending on the installation environment and local harmonic regulations.
PROFINET PN onboard, no IO expansion module
Fieldbus is integrated: PROFINET PN and Ethernet IP are built into the drive — no separate communications module required. The Intelligent Operator Panel (IOP) is included for local parameter access and commissioning. The drive ships without IO expansion modules; if additional I/O is needed beyond what the base unit provides, a separate expansion card must be ordered. This keeps the BOM clean for standard applications.
IP20, frame FSF, ambient limits
IP20 / UL open type — requires installation in a cabinet or enclosure with a minimum of IP54 to keep dust and moisture off the power stage. Frame size FSF means the drive is physically large: packaging dimensions are 400 x 780 x 584 mm, so plan panel depth and gland plate access accordingly. Ambient temperature range is -20 to +45 °C. Above 45 °C the output current must be derated per the Siemens G120X manual — a common oversight when the drive is mounted in a closed cabinet with other heat sources.
