Siemens SINAMICS V20 6SL3210-5BE13-7UV1 0.37 kW 3-Phase VFD

Electrical Ratings

The Siemens SINAMICS V20 6SL3210-5BE13-7UV1 is a compact variable frequency drive for controlling the speed of compatible three-phase AC motors. Its exact order code identifies an unfiltered 380–480 V three-phase-input version in frame size FSA. Siemens rates the unit at 0.37 kW for both Low Overload (LO) and High Overload (HO) modes, with a 1.30 A rated output current. The manufacturer also lists 0.50 hp under its 480 V NEC rating basis. The input line specification is 380–480 V AC, with a permitted tolerance of −15%/+10% and a line frequency of 47–63 Hz. The output is three-phase AC; the manufacturer gives 400 V IEC and 480 V NEC rating references. Output frequency is adjustable from 0 to 550 Hz. That range is the converter capability rather than permission to run any motor or driven machine at its maximum frequency.

Control Modes and Overload Performance

The V20 is intended for variable-speed motor duties in general machinery. The Siemens operating instructions describe V/f-based speed control and commissioning functionality for suitable asynchronous motors. Any specific motor type or advanced control method must be checked against the manual and the motor nameplate before commissioning. Siemens specifies a Low Overload capacity of 110% of rated output current for 60 seconds within a 300-second cycle; High Overload allows 150% for 60 seconds within a 300-second cycle. Both modes list the same 0.37 kW rated output and 1.30 A continuous output for this exact article. These are temporary capacities, not alternative continuous output-current ratings. Acceleration, motor loading, installation and thermal conditions still require evaluation.

Communication and Configuration

Built-in communication is listed by Siemens as USS and Modbus RTU. These are protocols; the installer should consult the connection and parameter chapters of the V20 operating instructions to establish the actual communication terminals, wiring, bus termination and supported operating settings. The product has a built-in Basic Operator Panel (BOP) for local parameter setup and drive operation. Siemens documents four digital inputs, two digital outputs, two analog inputs and one analog output in its product configuration. Additional devices, remote operating accessories or controllers should not be assumed to be included. Protocol availability does not imply that the drive includes an Ethernet interface.

EMC Filter and Braking

The exact Siemens datasheet marks the integrated filter class as Unfiltered. This distinguishes 6SL3210-5BE13-7UV1 from the corresponding filtered CV1 configuration and the earlier CV0 product generation. External EMC provisions and compliant installation may therefore be required for a particular environment. Importantly, Siemens explicitly lists “With integrated braking chopper: Yes” for this exact part. A built-in chopper is not the same as an included braking resistor. Any external resistor, duty-cycle limit, wiring and selection requirements must be established from manufacturer instructions and the intended load. Do not assume an external resistor is supplied in the converter package.

Installation and Environmental Conditions

The converter uses frame size FSA, with manufacturer dimensions of 90.0 × 150.0 × 145.5 mm (width × height × depth). The enclosure degree of protection is IP20 / UL open type and is not weatherproof. Siemens specifies convection cooling for this 0.37 kW version. Wall mounting and side-by-side mounting are listed; the actual spacing and protective enclosure must follow the current installation manual. The datasheet lists an operating ambient of −10 to 60 °C but directs users to observe derating at and above 40 °C. It identifies 1,000 m as the reference installation altitude, up to 95% maximum operating relative humidity, and motor-cable limits of 10 m shielded or 50 m unshielded. Environmental constraints and local electrical standards determine the final cabinet layout.

Applications and Selection Guidance

The SINAMICS V20 can be evaluated for compact conveyors, small fans, light-duty pumps, mixers, machine feeders and other basic variable-speed duties when the connected three-phase motor is electrically compatible with the converter’s 0.37 kW and 1.30 A continuous rating. These are technically appropriate application examples, not a statement that Siemens certifies this exact drive for each use case. Braking-intensive loads need a properly engineered braking resistor and may require additional verification of duty and heat dissipation. A machine with high starting torque or unusual acceleration requirements should be evaluated against the complete Siemens manual. The motor nameplate, supply quality, protection devices and site EMC requirements remain critical to selection.

Exact Variant Verification

The order code 6SL3210-5BE13-7UV1 identifies the unfiltered V1 version. Do not substitute data from the filtered 6SL3210-5BE13-7CV1 or from the earlier generation UV0/CV0 articles. Rated power is 0.37 kW, rated output current is 1.30 A, the supply is three-phase 380–480 V AC, and frame size is FSA. The exact-part datasheet also confirms the integrated braking chopper and no integrated EMC filter. The official Siemens datasheet should take priority where a reseller description differs.
