75 kW, 150% overload, PROFINET PN — the G120C FSF frame
The 6SL3210-1KE31-4UF1: It ships in the FSF frame size (708 x 305 x 357 mm), IP20 / UL Open Type, so it's a panel-mount unit — no enclosure needed if the cabinet is clean and dry, but you'll want to account for the 745 x 469 x 385 mm shipping package when planning inbound logistics. The integrated PROFINET PN fieldbus means it plugs straight into a Siemens S7-1500 or any PN controller without a separate communication module — the drive appears as a PROFIdrive device on the network, and the Safe Torque Off (STO) function is built in, no extra safety relay needed for the stop category.
I/O complement and unfiltered input — what you get and what you add
The I/O interface gives you 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed reference, run/stop, and fault feedback without an extra I/O block. The analog input accepts 0-10 V or 0/4-20 mA, configurable via the commissioning software. This is the unfiltered variant — there's no internal line filter for conducted emissions. In a European or North American panel, you'll need an external EMC filter (Siemens recommends the 6SL3203-0CE23-2AA0 for this frame) to meet EN 61800-3 Category C2 or C3 limits. If the drive feeds a motor cable longer than 25 m, the filter is mandatory for compliance. The 150% overload for 3 seconds is a short-time duty rating — the drive's thermal model tracks the IGBT junction temperature, and the overload is available only when the drive is below its base load. For continuous high-torque applications, size up to the next frame.
Active production, compliance, and ordering
RoHS compliant since 13-02-17, with a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w — this matters for waste documentation in EU markets. Export control is AL N / ECCN 9N9999, so no special license needed for most commercial shipments. The group code is R220, product group 5820, for your internal cataloging or ERP cross-reference.
