Siemens SINAMICS V20 15 kW 3-Phase VFD 6SL3210-5BE31-5CV0

The Siemens SINAMICS V20 6SL3210-5BE31-5CV0 is a 15 kW (20 HP) basic variable frequency drive for controlling a suitable three-phase AC motor from a three-phase industrial supply. This exact CV0 order number belongs to the 380–480 V SINAMICS V20 range and is fitted with an integrated Class A EMC filter and an integrated braking chopper. It has a built-in basic operator panel (BOP), IP20/UL open-type construction and an FSD frame. The manufacturer’s continuous output rating is 31.00 A under both Low Overload and High Overload classifications.

Electrical Ratings

The converter accepts a three-phase 380–480 V AC nominal supply, with a manufacturer-listed tolerance of −15% to +10% and line frequency of 47–63 Hz. Its three-phase rated output voltage is shown as 400 V according to IEC and 480 V according to NEC. Siemens lists 15.00 kW for both Low Overload (LO) and High Overload (HO), with an official 20.00 HP designation for the 480 V NEC rating. The rated output current is 31.00 A in either duty mode. The datasheet lists an output-frequency setting range of 0–550 Hz and a 4 kHz nominal pulse frequency. The 480 V HP/current basis applies to the 440–480 V supply range. Always match motor nameplate voltage/current and any required derating rather than equating the maximum converter frequency with an acceptable motor speed.

Control Modes and Performance

The SINAMICS V20 is intended for adjustable-speed motor applications using its parameterized drive-control functions. The product family supports voltage/frequency control, including configurable V/f characteristics; consult the applicable V20 operating instructions for the exact parameters and motor restrictions. Siemens specifies Low Overload operation at 110% of rated output current for 60 seconds per 300-second cycle, and High Overload operation at 150% for 60 seconds per 300-second cycle. These are temporary overload capabilities, not continuous 34.1 A or 46.5 A ratings. Both duty modes are documented at 15 kW and 31 A for this exact order number. Starting, acceleration, load inertia, thermal behavior and drive settings must be validated in the full machine design.

Communication and Configuration

This converter supports USS and Modbus RTU communication according to Siemens’ exact-part datasheet and catalog. Its built-in basic operator panel supports local commissioning and parameter adjustment. Siemens documents four digital inputs, two digital outputs (one relay changeover contact and one transistor output), two analog inputs that can also function as additional digital inputs, and one analog output. Protocol support does not imply a built-in Ethernet interface. Any networking accessories, cable arrangements, installation restrictions or software tools must be assessed separately against Siemens’ official operating instructions. The drive’s parameters and supported control functions should be checked for the actual automation system before commissioning.

EMC, Braking and Built-in Functions

The 6SL3210-5BE31-5CV0 contains an integrated Class A EMC filter; Siemens’ SINAMICS V20 catalog groups the filtered 380–480 V three-phase models under EN 61800-3 Category C3 for industrial second-environment installations. Appropriate shielded motor cabling, grounding, cabinet wiring and installation practices remain necessary for the intended compliance arrangement. The exact-model datasheet explicitly states that an integrated braking chopper is present. This does not mean an external braking resistor is supplied. Select a compatible resistor and verify its braking duty, resistance, thermal protection and wiring in the official manufacturer instructions before enabling dynamic braking. Do not assume that the drive’s protective alarms represent a certified machine-safety function.

Installation and Typical Applications

The FSD frame measures 240.0 mm wide, 206.5 mm high and 172.5 mm deep; net weight is listed as 4.30 kg. Siemens documents wall, through-hole and side-by-side mounting possibilities and external-fan cooling. The stated installation altitude is 1,000 m; higher-altitude use requires checking Siemens derating rules. The published ambient operating range is −10 to 60 °C, with derating guidance at temperatures of 40 °C or higher. Maximum motor-cable lengths are 25 m shielded and 50 m unshielded in the datasheet, subject to the required EMC arrangement. IP20/UL open type requires a suitable enclosure for dust, moisture, contact and environmental exposure. Suitable engineering candidates include correctly sized pumps, fans, conveyors and basic machinery with compatible three-phase motors, provided required torque, starting and deceleration performance are checked.

Exact CV0 Variant Verification

The part number 6SL3210-5BE31-5CV0 identifies the 15 kW filtered version and must not be substituted silently with 6SL3210-5BE31-5UV0, which is the unfiltered counterpart. It should also not be confused with neighboring 11 kW or 18.5 kW V20 models. The FSD dimensions, 31 A current, Class A integrated filter and integrated braking chopper in this listing are documented for this exact code. Siemens manufacturer pages sometimes use the wording ‘integrated filter C3’ while the technical datasheet calls the integrated filter ‘Class A’; these are distinct classification conventions preserved here rather than combined into a new certification claim.
