Drive specs and what they mean for fit
The Siemens 6SL3211-0AB21-5AB1 is a SINAMICS G110-CPM110 AC Drive, listed as a spare part. It delivers 1.5 kW in both constant-torque (CT) and variable-torque (VT) modes, so it handles the same load regardless of duty profile — no derating needed when switching between a conveyor and a fan application. The CT overload rating of 150% for 60 seconds gives it enough headroom for starting high-inertia loads like a small centrifuge or a roller conveyor without tripping. Input is 200-240 VAC single-phase, +10/-10%, 47-63 Hz, with an integrated EMC filter. That means it drops straight into a standard North American or European single-phase line without an external line reactor for basic conducted-emission compliance. The RS-485 interface with USS protocol handles multi-drop communication to a PLC or HMI — no analog input on this variant, so speed reference comes over the serial link or via the terminal strip's digital inputs.
Physical fit and panel integration
The drive measures 160 x 140 x 142 mm (HxWxD) and carries an IP20 degree of protection. Mounting is through standard screw holes on the backplate.
