Drive selection memo
The Siemens 6SL3210-1KE14-3AC0 is a SINAMICS G120C drive rated for 1.5 kW output with 150% overload capability for 3 seconds, fed from a 380-480 VAC three-phase supply at 47-63 Hz. The integrated Class A EMC filter saves panel space on a DIN-rail mount, and the IP20 / UL Open Type enclosure suits clean, indoor cabinet environments. Onboard I/O includes 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed/start-stop control without an expansion module.
Integration notes
Frame size FSA (196 x 73 x 203 mm HxWxD) fits a standard DIN-rail enclosure; the compact width leaves room alongside a line reactor or output choke. CANopen is integrated on the control board — no separate communication module needed. Safe Torque-Off (STO) is built in, eliminating the need for an external safety relay on the power stage for stop category 0 applications.
