Drive selection memo
The Siemens 6SL3211-0AB13-7UB0 is a SINAMICS G110 CPM110 AC drive sized for 0.37 kW constant-torque or variable-torque loads on a single-phase 200-240 VAC supply, 47-63 Hz. The RS485 interface runs the USS protocol for serial communication with a PLC or HMI. No built-in EMC filter — factor an external filter if the installation must meet conducted emission limits for the residential or light-industrial environment.
What the ratings mean for fit
The 0.37 kW CT/VT rating matches a small induction motor — think a 0.5 HP pump, a compact conveyor, or a fan under 1 A full-load current. The 150% overload for 60 seconds gives headroom for starting inertia without oversizing the drive. IP20 means it lives inside a panel or enclosure, not on the machine frame in a washdown zone. Ambient range -10 to +50 °C covers most control rooms and electrical rooms; derate above 40 °C per the thermal curve in the manual.
