Drive selection memo
The Siemens 6SL3210-5HB10-4UF0 is a SINAMICS S210 servo drive sized for a 0.4 kW motor on single-phase 200-240 VAC mains. Output is 2.4 A, 0-550 Hz, meaning it'll run a small servo motor for indexing, positioning, or light conveyor work — not a heavy crusher, but fine for a feed gate or sampler. Frame size B keeps the footprint tight at 55 x 170 x 170 mm (WxHxD), IP20 so it needs a clean, dry enclosure; no washdown tolerance here. Input voltage tolerance is -10%/+10% at 45-66 Hz, so it handles weak or noisy single-phase supplies common in remote plants. The output voltage follows the input (0 to supply V), meaning no internal boost stage — motor torque at low speed depends on the incoming line quality.
Panel integration notes
IP20 means the drive goes inside a panel with a minimum of IP54 or better enclosure if the environment has dust or moisture. Frame B dimensions (55 x 170 x 170 mm) leave room for the mandatory DC-link braking resistor on the side — check the mounting template for the resistor bracket before laying out the backplate. DIN-rail mount is standard for this frame; verify the rail type (35 mm) and that the drive's cooling fins have 50 mm clearance above and below for natural convection.
