The Siemens 6SL3211-0AB21-5AB0 is a SINAMICS G110 CPM110 AC drive rated for 1.5 kW constant torque and 1.5 kW variable torque, fed from a single-phase 200-240 VAC supply (+10/-10%, 47-63 Hz). It carries a built-in Class A EMC filter, so no external filter is needed for standard industrial environments — saves a DIN-rail slot and a wiring step. Communication is via RS485 using the USS protocol, which is the native serial link for Siemens drives. No fieldbus module required for basic speed control from a PLC or operator panel; just a twisted-pair daisy chain. The drive delivers 150% overload for 60 seconds, enough to handle short-duration load spikes on conveyors or pumps without tripping. Ambient temperature range is -10 to +40 °C; above that, derate per the thermal curve.
Dimensions are 160 mm high, 140 mm wide, 142 mm deep. IP20 rated, so it is intended for clean, dry panel environments only; no washdown or outdoor duty. The drive ships without a BOP (Basic Operator Panel) and without an analog input — control is via the RS485 USS link or the digital I/O terminals on the front. If you need local speed pot or display, order the BOP separately.
