The Siemens 6SL3211-0KB15-5BA1 is a SINAMICS G110-CPM110 AC drive — a spare-part variant built for cooling plate installation. It delivers 0.55 kW constant torque (CT) and 0.55 kW variable torque (VT) from a 200-240 VAC single-phase supply, with an integrated EMC filter for the line side. The IP20 enclosure and flat heat sink mean this drive is designed to be mounted against a metal panel or machine frame that acts as the heatsink; it is not a stand-alone cabinet unit.
What the ratings mean for fit
The 0.55 kW CT rating covers constant-torque loads like conveyors and positive-displacement pumps. The same 0.55 kW VT rating handles variable-torque loads such as centrifugal fans and pumps — no oversizing needed for fan curves. The 150% overload for 60 seconds gives enough headroom for starting inertia without tripping. The integrated filter (Class A or B, not specified here) attenuates conducted emissions, so the drive can be used in residential or light-industrial environments where line noise is a concern. The analog input accepts a standard 0-10 V or 4-20 mA speed reference.
Mounting and integration
This drive uses a flat heat sink for cooling plate installation — the rear face must be bolted to a metal surface that conducts heat away. Ambient temperature range is -10 to +50 °C. The 150 x 90 x 101 mm (HxWxD) footprint fits into tight panel spaces. No BOP (Basic Operator Panel) and no RS-485 interface are included, so commissioning requires the optional BOP or a PC connection via the USS protocol (if available on this variant).
