The Siemens 6SL3210-1KE22-6AC1 is a SINAMICS G120C spare-part drive rated at 11.0 kW with 150% overload capability for 3 seconds. It runs on 380-480 V 3AC, 47-63 Hz, and includes an integrated class A EMC filter. The unit is IP20 / UL Open Type, sized FSC (295 x 140 x 203 mm), and requires an external 24 V supply.
Key ratings and what they mean
The 11.0 kW rating at 150% overload for 3 seconds means this drive can handle short-duration peak loads — typical for accelerating a conveyor or pump motor — without tripping. The 380-480 V 3AC input covers standard European and North American industrial mains. The integrated class A filter meets conducted emission limits for most industrial environments; no external filter needed unless the installation requires class B (residential) limits. Safe Torque Off (STO) is integrated, which means the drive can safely disable torque without disconnecting the motor cable — a requirement for safety circuits up to SIL 3 / PL e. The I/O interface (6 DI, 2 DQ, 1 AI, 1 AQ) covers basic control and feedback; for more I/O, a terminal expansion module can be added via the slot. CANopen fieldbus is onboard, so the drive can be networked with other CANopen devices without an extra communication module. The IP20 enclosure is suited for clean, dry cabinet mounting — not for washdown or outdoor exposure.
Deployment context
This drive mounts in a standard IP20 cabinet — panel builders will need to provide the external 24 V supply and ensure the cabinet has adequate airflow for the FSC heatsink. The CANopen bus connects via the integrated RJ45 or screw terminal; the STO circuit requires a separate safety relay or PLC with safe outputs. The 150% overload for 3 s is useful for applications like a centrifuge or crusher that sees short peak torque demands.
