Drive specification and integration constraints
The Siemens 6SL3211-0AB12-5UB0 is a SINAMICS G110 CPM110 AC drive rated for constant-torque and variable-torque loads at 0.25 kW on a 1AC 200-240V supply. The RS485 interface uses the USS protocol for serial communication; no analog input is fitted on this variant, so speed reference comes exclusively over the serial link or via the optional BOP (not included). The CT overload capability of 150% for 60 seconds means it can handle short-duration peak loads common in conveyor start-up or light indexing moves — useful for material-handling applications where the motor sees intermittent over-torque. The 150 x 90 x 116 mm (HxWxD) IP20 enclosure fits a standard control-panel backplate with DIN-rail mounting. The absence of an internal EMC filter means the installer must provide an external filter for first-environment compliance (EN 61800-3 Category C2 or C1).
