The Siemens 6SL3210-1KE21-7AB0 is a SINAMICS G120C drive rated at 7.5 kW with a 150% overload capability for 3 seconds, running on a 380-480 VAC 3-phase supply at 47-63 Hz. It includes an integrated Class A EMC filter, so it meets conducted emissions limits for most industrial environments without an external filter — saves a DIN module on the rail.
I/O and safety
The I/O interface gives you 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic conveyor or pump control without an add-on module. Safe-Torque-Off is integrated, which means you can wire a safety relay directly to the drive for a category 0 stop per EN 61800-5-2 without an external safety card. That keeps the wiring clean and the panel width tighter.
Fieldbus and panel fit
Fieldbus is integrated: USS and MODBUS RTU are both on board, so no option card needed for those protocols. The drive is IP20 / UL Open Type — it's meant for a clean, dry cabinet, not washdown. Frame size FSB measures 196 x 100 x 203 mm (HxWxD), so it fits on a standard DIN rail and leaves room alongside the line reactor or braking resistor.
