Siemens SINAMICS V20 11 kW 3-Phase VFD 6SL3210-5BE31-1UV0

Electrical Ratings

The 6SL3210-5BE31-1UV0 accepts a three-phase AC supply at a nominal 380–480 V, with a manufacturer-specified permitted line-voltage tolerance of −15% to +10% and an input frequency of 47–63 Hz. It provides a three-phase motor output. Siemens lists 400 V IEC and 480 V NEC output-rating bases; these are nominal rating bases rather than a promise that the output voltage will exceed the available input supply. The drive is rated for 11.00 kW at both Low Overload (LO) and High Overload (HO). Siemens also lists 15.00 HP in its NEC column for the specified 440–480 V voltage range. Rated output current is 25.00 A at the 400 V IEC basis and 21.00 A at the 480 V NEC basis. The maximum configured output frequency is 550 Hz, but a motor and driven machine must be approved for their actual operating speeds. Motor suitability requires a check of nameplate voltage, full-load current, insulation, cooling and load characteristics.

Control Modes and Performance

SINAMICS V20 is Siemens’ basic variable-frequency-drive family intended for practical motor speed regulation. Its drive parameterization supports applications where adjustable frequency, controlled acceleration, and controlled deceleration are required. Avoid assuming advanced servo positioning or certified functional-safety features. The manufacturer’s exact-part sheet specifies two overload duty classifications at this rating. Low Overload (LO) permits 110% of rated output current for 60 seconds with a 300-second cycle. High Overload (HO) permits 150% for 60 seconds with a 300-second cycle. Both modes list 11 kW rated power; these short-duration percentages must not be misrepresented as continuous current. The correct overload regime depends on load conditions, installation and thermal derating.

Communication and Configuration

The manufacturer identifies USS and Modbus RTU as the supported communications for this exact product. Protocol support should not be interpreted as an Ethernet interface, or as proof that an optional gateway is supplied. Siemens’ product listing identifies a built-in basic operator panel (BOP) for local setup and operation. It also lists four digital inputs, two digital outputs, two analog inputs and one analog output as family/product configuration information. Installation and parameter settings should follow Siemens’ operating instructions. For a PLC connection, check the required wiring, serial electrical interface, address, baud rate, parameter mapping and grounding before commissioning.

Braking, EMC and Built-in Functions

The 6SL3210-5BE31-1UV0 is explicitly specified as unfiltered: it does not incorporate an EMC input filter. Any needed external EMC filtering, shield termination, cabinet arrangement and cable practice must be selected according to the installation environment and applicable standards. Importantly, Siemens’ exact-part datasheet explicitly says an integrated braking chopper is present on this 11 kW UV0 variant. This differs from some lower-power UV0 models, so the suffix alone cannot determine braking hardware. A braking chopper is not a braking resistor: an external resistor and its sizing, duty cycle, temperature safeguards and installation requirements must be confirmed separately. Do not assume a resistor is included with the VFD.

Installation and Typical Applications

Siemens identifies IP20 / UL open-type protection and an FSD frame. The physical dimensions are 240.0 mm wide, 206.5 mm high and 172.5 mm deep. The datasheet shows external-fan cooling and installation-altitude basis of 1,000 m. Its stated operation temperature span is −10 to 60 °C, with derating required at 40 °C or above; this is not a blanket assurance of full output at 60 °C. The specified maximum shielded motor cable length is 25 m and unshielded length 50 m, subject to installation conditions. This drive can be considered for properly matched industrial fans, pumps, conveyors, mixers, and other adjustable-speed induction-motor systems when torque requirements, cable lengths, thermal conditions and protective devices are confirmed. These are technically suitable suggestions, not guarantees of compatibility with every machine.

Exact Variant Verification

This workbook covers the complete order number 6SL3210-5BE31-1UV0, not the related 6SL3210-5BE31-1CV0. The UV0 device is unfiltered, whereas the CV0 is a filtered configuration. Do not transfer filter requirements or image evidence from another part number. Siemens lists a rated output current of 25.00 A for its 400 V IEC column and 21.00 A for the 480 V NEC column; the latter is subject to its 440–480 V note. The exact UV0 datasheet confirms the built-in braking chopper, so it must not be omitted merely because some smaller UV0 drives lack one. Check the machine’s electrical design and the product nameplate before ordering or substitution.
