The Siemens 6SL3211-0AB21-5UB1 is a SINAMICS G110-CPM110 AC Drive — a compact, basic variable-frequency drive for constant-torque (CT) and variable-torque (VT) loads up to 1.5 kW. It operates on a 200-240 V single-phase supply, ±10%, 47-63 Hz, and communicates over RS-485 using the USS protocol. Rated for IP20, it is intended for enclosure-mounted installations where the drive is protected from dust and moisture ingress. The 1.5 kW rating applies to both CT and VT duty, with a 150% overload capability for 60 seconds — enough to handle short-duration load spikes on pumps, fans, or small conveyors without tripping.
Ambient temperature range is -10 to +40 °C; above 40 °C, derate the output current per the drive's thermal curve. The unfiltered variant means it lacks an internal EMC filter, so an external filter may be required for compliance with conducted-emission limits in residential or light-industrial environments.
