Drive selection memo
The Siemens 6SL3210-1KE17-5AC0 is a SINAMICS G120C drive rated for 3.0 kW output with a 150% overload capability for 3 seconds — enough headroom for a conveyor start or a pump breakaway torque without oversizing the frame. Input accepts 380-480 VAC three-phase, +10/-20%, 47-63 Hz, so it covers standard European and North American line voltages within one unit. The integrated Class A EMC filter means this drive meets conducted emission limits for industrial environments without an external filter block — saves a DIN-rail slot and a wiring step. The IP20 / UL Open Type enclosure suits cabinet-mount installation; keep it inside a panel rated for the environment. Safe-Torque-Off is integrated per the description, so you can wire the STO circuit directly to a safety relay or safety PLC without a separate option module — reduces the safety loop component count and the wiring check at commissioning.
Fieldbus and I/O
CANopen is the integrated fieldbus on this variant — no optional communication board needed for CANopen networks. The I/O complement (6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output) covers basic local control and feedback without an external I/O slice. The FSA form factor (196 x 73 x 203 mm HxWxD) is the smallest G120C frame size. Plan for 73 mm of panel width per drive, plus clearance for cabling and heat dissipation. The integrated filter and STO are internal, so no add-on modules eat into the envelope.
