Drive selection memo
The Siemens 6SL3210-5EE27-5UV0 is a SINAMICS V20 drive rated for 7.5 kW on a 380-480 V 3 AC supply, with a 150% overload capability for 60 seconds — enough headroom for pump, fan, or conveyor starts that need short-term torque above the continuous rating. Input range is 380-480 V 3 AC -15/+10% at 47-63 Hz; the unfiltered variant means you'll need an external line reactor or EMC filter if the installation must meet conducted emission limits for the environment. Built-in I/O includes 4 digital inputs, 2 digital outputs, 2 analog inputs, and 1 analog output; fieldbus is USS or MODBUS RTU over the integral RS-485 port, with the basic operator panel (BOP) for local parameter access. Enclosure is IP20 / UL open type — intended for clean, dry panel environments where the drive is protected from dust and moisture; dimensions are 206.5 x 240 x 172.5 mm (D x W x H).
