Drive specs and what they mean for your line
The Siemens 6SL3211-0KB17-5BA0 is a SINAMICS G110 CPM110 AC drive rated for 0.75 kW in both constant-torque (CT) and variable-torque (VT) duty, running from a single-phase 200-240 VAC supply at 47-63 Hz. That CT rating means it can handle a constant-load application like a conveyor or positive-displacement pump at full rated torque across the speed range, while the VT rating covers centrifugal fans and pumps where torque drops with speed. The drive includes a built-in Class B EMC filter, so it meets conducted-emission limits for residential and light-industrial environments without an external filter. The CT overload capability is 150% for 60 seconds, which gives you headroom for starting inertia or short-duration peak loads — enough to get a loaded conveyor moving without tripping on the I²t curve.
Mounting and environment — no heatsink, tight panel fit
This drive is IP20 rated and ships without a heatsink, so it relies on the panel's own airflow or a backplate for thermal management. The dimensions are 150 x 90 x 101 mm (HxWxD), which fits a standard DIN-rail enclosure but needs clearance above and below for convection cooling. Ambient temperature range is -10 to +40°C without the optional BOP (Basic Operator Panel) fitted — if you add the BOP, check the derating curve for higher ambient.
What the analog input and control setup tell you
The drive includes an analog input, so it accepts a 0-10V or 4-20 mA speed reference from a PLC or potentiometer. No onboard fieldbus (PROFIBUS, PROFINET) — this is a basic speed-control drive for standalone or simple networked applications via the analog signal. If you need digital communication, you would step up to the G120 series or add a communication module (check compatibility).
