Siemens 6SL3210-5BE21-5CV1 is a SINAMICS V20 basic converter rated 1.5 kW on 380-480 V 3-phase AC input, delivering 150% overload for 60 seconds. It carries an integrated EMC filter C3 and a built-in braking unit, so it handles short-duration high-torque demands without an external brake resistor for most pump and fan profiles. The IP20 / UL open-type enclosure means it lives inside a panel — gland plate clearance and ambient derating apply. I/O complement: 4 digital inputs, 2 digital outputs, 2 analog inputs, 1 analog output. Fieldbus is USS and MODBUS RTU via the built-in BOP (Basic Operator Panel) interface. That covers point-to-point or daisy-chain control to a PLC without an option card. Product class C — manufactured or produced to order, not a stocked shelf item. That matches the V20 supply model: Siemens builds these in batches against demand.
Lifecycle stage is mature; product status is Active per Siemens. This drive remains in the current SINAMICS V20 catalog. RoHS compliant since 2010-07-05. No other SVHC candidates flagged in the current listing. Group code R220, product group 5681 for customs and catalog classification.
Integration notes
Frame size A: 90 x 166 x 145.5 mm (WxHxD). Shipping box dimensions 225 x 180 x 120 mm. Panel cutout and gland plate must clear the heatsink depth; side clearance for airflow per the V20 manual (typically 50 mm on each side). Integrated MODBUS RTU at the BOP port — no separate comm module needed. Four DI, two DO (relay or transistor depending on variant), two AI (0-10 V or 0/4-20 mA selectable), one AQ. Enough for a standalone pump or conveyor drive without an expansion I/O. Built-in braking unit handles the regenerative energy for most stopping profiles at this power level. For vertical loads or rapid deceleration cycles, confirm the internal brake resistor duty cycle against your application — 150% overload for 60 s is the thermal budget.
