Drive selection memo
The Siemens 6SL3210-1KE18-8UC1 is a SINAMICS G120C compact drive rated for 4.0 kW with 150% overload for 3 seconds, on a 380-480 V three-phase supply at 47-63 Hz. It integrates CANopen fieldbus and Safe Torque Off as standard, with an I/O complement of 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output. The IP20 / UL Open Type enclosure suits cabinet mounting; the FSA frame size (196 x 73 x 203 mm) fits standard panel layouts.
Integration notes
The G120C requires an external 24 V supply for the control electronics. The CANopen interface is integrated on the control unit; no option card is needed for basic fieldbus communication. Safe Torque Off is onboard, eliminating the need for a separate safety relay in many guarding applications. The unfiltered variant means an external line reactor or filter may be needed for compliance with EN 61800-3 Category C2 or C3 conducted emissions limits, depending on installation environment.
