Drive selection memo
The Siemens 6SL3210-1KE12-3UP0 is a SINAMICS G120C compact drive rated for 0.75 kW output power on a 3-phase 380-480 VAC supply. It delivers 150% overload for 3 seconds — enough to handle short-duration load spikes on small conveyors, pumps, or fans without oversizing the drive frame.
Integration constraints
Housed in size FSA (196 x 73 x 203 mm, H x W x D), this drive fits the standard DIN-rail footprint for panel mounting. The unfiltered variant means an external line reactor or filter may be needed for harmonic compliance, depending on the supply network. IP20 / UL Open Type rating restricts it to clean, dry enclosures — no washdown or outdoor placement. The I/O interface provides 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — sufficient for basic speed control and status feedback without an add-on I/O module. Safe Torque Off (STO) is integrated, eliminating the need for a separate safety relay in many stop-function applications.
