The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — is enough for basic speed control and feedback on a standalone machine; for more complex sequencing you'd add a PLC over the CANopen bus. Integrated Safe Torque-Off (STO) meets the safety-circuit requirement for unexpected-start prevention per EN 61800-5-2, so you can wire the safety relay directly to the drive without an external contactor for the power disconnect. The FSB frame size measures 196 x 100 x 203 mm (H x W x D) with IP20 / UL Open Type protection — it mounts inside a clean, dry control cabinet, not on the machine frame. CANopen is the onboard fieldbus; no option card needed for that protocol. If the line speaks PROFIBUS or PROFINET, you'll need a separate communication module (the G120C family accepts them on the side slot).","metaTitle":"Siemens 6SL3210-1KE21-3UC0 SINAMICS G120C, 5.5 kW, CANopen","metaDescription":"Siemens SINAMICS G120C drive, 5.5 kW, 150% overload, 380-480 VAC, CANopen, Safe Torque Off, IP20.
