Siemens SINAMICS V20 6SL3210-5BB12-5UV1 0.25 kW 1-Phase VFD

Product Overview

The Siemens SINAMICS V20 6SL3210-5BB12-5UV1 is a compact basic AC frequency converter for adjustable-speed operation of suitable three-phase AC motors. This exact 0.25 kW variant belongs to the 200–240 V single-phase-input group and uses the smaller FSAA frame. Siemens identifies it as an unfiltered design; it should not be confused with the separately ordered filtered 6SL3210-5BB12-5BV1 variant. The drive provides an integrated basic operator panel (BOP), digital and analog I/O, and USS/Modbus RTU communication.

Electrical Ratings

The nominal line supply is 200–240 V AC, one phase, at 47–63 Hz. The Siemens technical datasheet reports a permissible line-voltage range of 200–240 V with −15%/+10% tolerance; installation design must follow the rated supply and local electrical conditions. The converter produces a three-phase output, with the Siemens datasheet listing 230 V IEC and 240 V NEC rated output references. Rated motor power is 0.25 kW for both low-overload (LO) and high-overload (HO) duty. The datasheet lists 0.25 hp for LO and 0.33 hp for HO under the applicable NEC voltage basis, so these manufacturer ratings should not be treated as interchangeable universal horsepower equivalents. Continuous output current is 1.70 A in LO and HO operation; these ratings do not indicate that the converter may continuously deliver its overload current. Output frequency is specified as 0–550 Hz, but any actual motor operating speed must remain within the motor and connected machine limits.

Control Modes and Performance

SINAMICS V20 supports adjustable frequency operation with drive-level commissioning and parameterization. The exact-model datasheet defines two distinct overload profiles: LO permits 110% of rated output current for 60 seconds in a 300-second cycle, while HO permits 150% for 60 seconds in a 300-second cycle. Because both duty classes show 1.70 A continuous current for this model, motor selection should still be based on the correct thermal, duty, load and cable conditions. More specific control algorithms or motor-type compatibility should be confirmed against the applicable Siemens operating instructions before stating a particular function is enabled or appropriate.

Communication and Configuration

Built-in communication is USS and Modbus RTU. These are named communication protocols, not evidence of an integrated Ethernet port. The product listing confirms a built-in basic operator panel for local setup and operation. Siemens also lists four standard digital inputs, two digital outputs, two analog inputs and one analog output. The two outputs comprise one relay changeover contact and one transistor output; the analog inputs may also serve as additional digital inputs according to the datasheet. Exact wiring, signal compatibility, parameter settings and network setup must be checked in the installation documentation.

Braking, EMC and Integrated Functions

This precise UV1 variant is supplied without an integrated EMC line filter. The Siemens datasheet explicitly says it has no integrated braking chopper; therefore, a built-in dynamic-braking transistor, included brake resistor, or resistor-ready installation should not be assumed. For installations with demanding deceleration or electromagnetic-compatibility conditions, verify external components and restrictions with Siemens selection documentation and applicable local requirements. Protective drive alarms should not be confused with certified safety functions.

Installation and Operating Conditions

The drive is rated IP20 / UL open type, which is not weatherproof or washdown protection. Siemens gives frame size FSAA and dimensions 68.0 × 142.0 × 107.8 mm (width × height × depth), with convection cooling and wall or side-by-side mounting. The technical datasheet identifies operating ambient temperature −10 to +60 °C but also requires derating at 40 °C and above. Standard installation altitude is listed as 1,000 m, and maximum operating relative humidity is 95%. Maximum motor cable lengths shown are 25 m for shielded and 50 m for unshielded cable, subject to the relevant installation instructions. Maintain appropriate enclosure protection, clearances, thermal design, earthing and circuit protection.

Typical Applications and Variant Identification

Within rated motor and load limits, this compact converter may be suitable for low-power speed-adjustment duties such as small fans, circulation pumps, light conveyors and process auxiliaries. These are engineering-use suggestions, not a Siemens guarantee for every machine. Suitability depends on starting torque, overload, braking needs, motor characteristics and environmental requirements. The full article number 6SL3210-5BB12-5UV1 identifies the unfiltered 0.25 kW FSAA version, whereas 6SL3210-5BB12-5BV1 refers to the filtered alternative and 6SL3210-5BB12-5UV0 identifies an older frame generation.
