Drive selection memo
The Siemens 6SL3210-1KE22-6AB0 is a SINAMICS G120C compact drive rated for 11.0 kW output with a 150% overload capability for 3 seconds — enough to handle high-breakaway-torque loads like a conveyor start or a pump clearing a blocked impeller. It runs on 380–480 V three-phase, 47–63 Hz, with an integrated Class A EMC filter, so it meets conducted emission limits for most industrial environments without an external filter. The Safe Torque Off (STO) function is built in, eliminating the need for a separate safety relay on the drive output. Fieldbus is USS and MODBUS RTU via the integrated port, covering the two most common serial protocols for PLC integration. The IP20 / UL Open Type enclosure means it is designed for installation inside a control cabinet — not for washdown or outdoor mounting.
