55 kW drive with a 150% overload punch for short-duration peak loads
The 6SL3210-1KE31-1AF1 is a SINAMICS G120C compact converter rated for 55.0 kW continuous output. The 150% overload capability for 3 seconds means it can handle short-duration peak loads like a crusher start or a centrifuge spin-up without oversizing the drive frame. Input accepts 3AC 380-480 V at 47-63 Hz, covering most global industrial mains. The integrated Class A EMC filter saves panel space and avoids an external filter for most installations — but check your local mains impedance and cable length; long motor cables may still need an output dV/dt filter to protect winding insulation.
Fieldbus and I/O — what connects where
PROFINET PN is on board, so this drive slots directly into a Siemens S7-1500 or ET 200SP controller without a separate communication module. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers basic speed setpoint and run/stop control; for more I/O you add a terminal module or use the fieldbus for everything. Safe Torque Off (STO) is integrated per the description, which means you can wire the safety relay directly to the drive without an external safety module — simplifies the safety circuit for a Category 3 / PL d stop function.
Panel fit and compliance paperwork
IP20 / UL Open Type means it is intended for a clean, dry enclosure — no washdown or outdoor mounting without a separate cabinet. RoHS compliant since 2017-02-13, with a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w. Export control is AL:N / ECCN:9N9999, which typically means no license required for most destinations — but verify against your end-user and final country.
