Drive selection memo
The Siemens 6SL3210-5BB12-5AV0 is a SINAMICS V20 spare-part drive rated 0.25 kW on a 200-240 V 1-phase AC supply with ±10% tolerance. The integrated EMC filter C2 meets conducted emission limits for industrial environments — no external filter needed for most CE-marked panels. The 150% overload for 60 s handles short-duration peak loads like a small conveyor start or a pump breakaway torque.
I/O and fieldbus
Onboard I/O includes 4 digital inputs, 2 digital outputs, 2 analog inputs, and 1 analog output — enough for a standalone VFD without an expansion module. Fieldbus is USS/MODBUS RTU over the built-in RS-485 port; the BOP (Basic Operator Panel) is included for local parameter access. The IP20 / UL open-type enclosure means it mounts inside a control cabinet, not on the machine frame.
