Drive for compact cabinet integration
The Siemens 6SL3210-1KE15-8AF1 is a SINAMICS G120C spare-part drive rated at 2.2 kW with 150% overload capability for 3 seconds, operating on 380-480 VAC 3-phase supply at 47-63 Hz. It integrates a class A EMC filter, PROFINET PN fieldbus, and Safe Torque Off (STO) as standard — covering the three most common requirements for a compact motor drive in a single FSA frame size (196 x 73 x 225.4 mm). The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — is enough for basic speed/start control and feedback without an external terminal block.
What the ratings mean for fit
The 2.2 kW rating at 150% overload for 3 seconds means this drive handles short-duration peak loads — useful for starting a loaded conveyor or a pump with high breakaway torque — without oversizing the drive for the continuous duty. IP20 / UL Open Type means it is intended for installation inside a clean, dry cabinet; not for washdown or outdoor deployment. The integrated class A filter meets EN 55011 for conducted emissions in industrial environments, so no external filter is needed for most standard installations. Safe Torque Off (STO) is a safety-rated motion function that removes torque-producing power to the motor without disconnecting the main supply — compliant with SIL 3 / PL e, allowing the drive to be used in safety circuits up to that level.
Lifecycle and sourcing reality
It is listed as a spare part, meaning it is stocked for replacement and service rather than for new machine builds; availability is steady through distribution channels. For a BOM freeze or a line-down replacement, this unit is sourced and quoted to order against an RFQ — current pricing and availability are confirmed at quote time.
Panel integration notes
The FSA frame (196 x 73 x 225.4 mm) mounts to a backplate or DIN rail; the 73 mm width fits a standard 8-module-wide enclosure section. External 24 VDC supply is required for the control electronics; the drive draws its power from the main 3-phase input for the motor circuit. The PROFINET PN interface uses a standard RJ45 connector; the I/O terminals accept 0.5-2.5 mm² wire. No special termination tools beyond a screwdriver are needed.
