Drive selection memo
The Siemens 6SL3210-5EE24-0UV0 is a SINAMICS V20 variable frequency drive rated for 4 kW on a 380-480 VAC three-phase supply, 47-63 Hz. It delivers 150% overload for 60 seconds — enough for starting high-inertia loads like fans or centrifugal pumps without oversizing the drive frame. The unfiltered variant means you'll need an external line reactor or sine-wave filter if the motor cable run exceeds 25 m or if the installation must meet EN 55011 Class A conducted emissions limits. I/O complement is four digital inputs, two digital outputs, two analog inputs, and one analog output. Fieldbus is USS or MODBUS RTU via the built-in RS-485 port; no option card needed. The built-in Basic Operator Panel (BOP) handles local start/stop and parameter editing without a separate HMI.
Panel integration notes
IP20 / UL open type enclosure means it is intended for installation inside a clean, dry control cabinet — not for washdown or outdoor locations. Size B footprint is 160 x 140 x 164.5 mm (W x H x D). Mounting on a standard DIN rail or backplate; leave at least 100 mm clearance above and below for airflow. The unfiltered design reduces heat dissipation inside the panel compared to a filtered variant, but still requires forced convection if multiple drives share the same enclosure.
