Duty cycle and overload capability for pump and fan loads
The 6SL3220-2YE56-1CB0: Rated 315 kW with a 135% overload for 3 s, 110% for 60 s, and 100% continuous for 240 s — this matches the cyclic loading profile of a centrifugal pump or fan where the drive must ride through a startup surge without tripping on overcurrent. The integrated RFI suppression filter is rated for category C3 on a 3AC 380-480 V supply, meaning it meets conducted emission limits for industrial environments without an external filter — a direct saving on panel space and wiring.
Fieldbus integration for building automation networks
MODBUS RTU, BACnet MS/TP, and USS are embedded on the control board — no separate communication module needed. BACnet MS/TP is the standard for HVAC building management systems, so this drive drops directly into a BTL-listed network without a gateway. The Basic Operator Panel (BOP) and IO expansion are included in the base unit, eliminating the need to order a separate HMI or I/O module for local commissioning and status readback.
Panel integration: size FSH and IP20 enclosure
Size FSH with IP20 / UL open type — the drive is designed for indoor cabinet mounting where the enclosure provides the environmental seal. The 800 x 1870 x 600 mm packaging dimensions give a rough envelope for the unit itself, but the actual cutout and mounting footprint should be verified against the Siemens dimension drawing for FSH.
Compliance and regulatory documentation
RoHS compliant since 11-03-20, and REACH Article 33 declares lead (CAS 7439-92-1) above 0.1% w/w in certain components — this matters for end-of-life reporting and waste disposal documentation in EU-regulated markets. Export Control Classification is AL: N / ECCN: EAR99H, meaning no special license is required for most industrial destinations, but the H suffix indicates it is subject to anti-terrorism controls — verify the end-user for sanctioned countries.
