90 kW rated power with 150% overload — motor sizing for pump, fan, conveyor duty
The 6SL3210-1KE31-7AF1 is a SINAMICS G120C compact converter rated at 90.0 kW continuous power with a 150% overload capability for 3 seconds. This overload headroom handles starting torque for centrifugal loads and short-duration peak demands on conveyors or extruders without oversizing the drive frame. Input accepts 3AC 380-480 V +10/-20% at 47-63 Hz, covering the global 400 V class mains range including 460 V北美 supplies without an external transformer. The integrated Class A EMC filter meets conducted emission limits for industrial environments — no external filter needed for most installations.
PROFINET-PN fieldbus and Safe Torque Off — commissioning and safety integration
Built-in PROFINET-PN interface connects directly into Siemens TIA Portal engineering, enabling parameter download, diagnostics, and drive commissioning over the same network cable as the PLC. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers basic speed reference and feedback without an expansion module. Safe Torque Off (STO) is integrated per the description, eliminating the need for an external safety relay for uncontrolled stop functions in guarding circuits. This reduces panel wiring and component count while meeting SIL 3 / PL e requirements when wired to a safety PLC or safety relay.
Size FSF, IP20 — panel space and environmental fit
The FSF frame size (708 x 305 x 357 mm HxWxD) and IP20 / UL Open Type protection mean the drive is intended for indoor cabinet mounting with filtered airflow. The 24 V external supply requirement (noted in the description) means a separate 24 VDC power supply must be budgeted in the panel for the control electronics — the drive does not derive its control power from the DC bus. Packaging dimensions of 745 x 469 x 385 mm indicate the shipping box is slightly larger than the drive itself — plan for handling clearance during panel installation.
Active production — sourcing for project builds and spares
RoHS compliance since 13-02-17 and REACH Article 33 declaration for lead (CAS 7439-92-1 > 0.1% w/w) are on file. The export control classification is AL: N / ECCN: 9N9999, which typically means no special licensing for most commercial destinations — confirm with your compliance team for your specific end-use.
