Siemens SINAMICS V20 6SL3210-5BE23-0UV1 3 kW 3-Phase VFD

The Siemens SINAMICS V20 6SL3210-5BE23-0UV1 is a 3.00 kW (4.00 HP) variable frequency drive for suitable three-phase motor applications, designed for a three-phase 380–480 V AC power supply. This exact UV1 version is unfiltered and includes an integrated braking chopper. It combines USS/Modbus RTU communication with a built-in Basic Operator Panel and IP20 construction for use in appropriately engineered industrial control installations. Exact identification matters because older UV0 and filtered CV1 part numbers have different onboard hardware.

Electrical Ratings

This converter accepts three-phase 380–480 V AC mains supply, with a manufacturer-stated -15%/+10% voltage tolerance and 47–63 Hz line frequency. Its rated motor output is 3.00 kW (4.00 hp in the manufacturer NEC rating). The output is three-phase, with manufacturer-listed nominal 400 V IEC and 480 V NEC ratings. Its continuous output current is 7.30 A in Low Overload (LO) and High Overload (HO) conditions; the operating-instructions model table likewise gives 7.30 A at 480 V under 4 kHz / 40°C conditions. The rated input current is 8.6 A. Motor selection must consider the motor nameplate current, voltage, installation conditions, and drive derating guidance.

Control Modes and Performance

The SINAMICS V20 is intended for adjustable-speed control of appropriate AC motors in industrial equipment. The documented output frequency setting range is 0–550 Hz; this is a converter capability, not a declaration that any connected motor or machine can safely operate at that speed. In Low Overload mode, Siemens lists 110% of rated output current for 60 seconds with a 300-second cycle. In High Overload mode, the capability is 150% for 60 seconds with a 300-second cycle. Both modes have a listed 7.30 A rated output current for this model. Overload operation is temporary and must not be confused with continuous output current. Commissioning parameters should match the motor and actual mechanical load.

Communication and Configuration

Integrated fieldbus communication supports USS and Modbus RTU, as specified by Siemens. These are serial fieldbus protocols; they should not be confused with integrated Ethernet capability. Siemens identifies a built-in Basic Operator Panel (BOP) for local configuration and operation. The product listing gives four digital inputs, two digital outputs, two analog inputs, and one analog output. Interface wiring, protocol parameters, supported functions, and permitted combinations should be checked in the installation and operating instructions. Any optional communication accessories or configuration software must be selected separately and must not be assumed to be supplied with this converter.

Braking, EMC and Built-In Functions

The 6SL3210-5BE23-0UV1 is explicitly unfiltered: no integrated EMC filter is listed. Appropriate electromagnetic compatibility measures depend on the installation, cabling, grounding, and any separately selected external filters. Unlike the earlier UV0 version, this UV1 part number has an integrated braking chopper, confirmed by Siemens. The braking chopper is not the same as a braking resistor: no external resistor is confirmed as included in the product scope. If the mechanical system needs resistive braking, a Siemens-compatible resistor and thermal protection must be engineered according to the manufacturer instructions. The BOP is built in, while any separately purchased braking or communication items must be identified as optional.

Installation and Typical Applications

Siemens classifies this product as frame size FSB with an IP20 / UL open-type degree of protection. The technical datasheet gives approximate dimensions 140 × 160 × 164.5 mm (W × H × D), while the listing rounds depth to 165 mm. Siemens identifies an external fan, and its documentation provides specific clearance, ambient temperature, altitude, wiring, and installation requirements. An appropriate control enclosure and protective measures may be needed for dust, water, accidental contact, and site conditions. Typical technically appropriate applications include compatible conveyor drives, packaging equipment, small process machines, and suitable pumps or fans, subject to motor ratings and load characteristics. The presence of a braking chopper can be valuable where controlled deceleration is required, but a correctly rated resistor and system assessment may still be necessary. No guaranteed energy-savings claim is made.

Exact Variant Verification

The complete manufacturer order number is 6SL3210-5BE23-0UV1. It is a three-phase 380–480 V AC, 3.00 kW, unfiltered, frame-size B V20 converter equipped with an integrated braking chopper. It must not be confused with 6SL3210-5BE23-0UV0 (older unfiltered model without the integrated braking chopper) or 6SL3210-5BE23-0CV1 (integrated EMC-filter variant). The filtered and unfiltered revisions have different installation implications. Confirm the full order number on the nameplate before replacement or procurement.
