Siemens SINAMICS V20 22 kW HO – 30 kW LO 3-Phase VFD 6SL3210-5BE32-2CV0

The Siemens SINAMICS V20 6SL3210-5BE32-2CV0 is a three-phase industrial variable frequency drive for controlling the speed of a compatible AC motor. This specific filtered FSE converter has different rated powers and currents in High Overload and Low Overload operation. Its exact model designation identifies the factory configuration and should be retained in technical selections, quotations and spare-part records.

Electrical Ratings

The 6SL3210-5BE32-2CV0 operates from a three-phase 380–480 V AC mains supply with an allowed voltage tolerance of −15% to +10% and line frequency of 47–63 Hz. It delivers a three-phase motor output with nominal 400 V IEC and 480 V NEC rating references. The documented output-frequency setting range is 0–550 Hz; the usable frequency and mechanical speed must remain within the connected motor and machine limits. The manufacturer’s 480 V HP/current values are valid in the 440–480 V range.

Distinct Low and High Overload Ratings

The central selection detail is its two different duty ratings. In Low Overload (LO) mode the drive is rated for 30 kW (40 HP) and 60 A at 400 V, or 52 A at 480 V. LO permits 110% rated output current for 60 seconds in a 300-second cycle. In High Overload (HO) mode the rated motor power is 22 kW (30 HP), with rated current 45 A at 400 V or 40 A at 480 V. HO permits 150% rated output current for 60 seconds per 300-second cycle. These values must never be combined as if 30 kW is available at the HO overload level. Verify expected torque demand, load cycling, thermal derating, and motor nameplate current before selecting the operating mode.

Motor Control and Performance

The SINAMICS V20 family is intended for variable-speed control of compatible three-phase asynchronous motors. It offers configurable frequency, acceleration, deceleration and operational protection parameters. The exact datasheet verifies rated inverter power and frequency values; suitability for a specific motor is conditional on its current, insulation, cooling and mechanical limitations. Reaching a high configurable electrical frequency does not authorize operating every motor at that speed. Confirm required starting torque and process characteristics using the Siemens operating instructions and commissioning parameters.

Communication and Configuration

For this exact part Siemens lists the built-in USS and Modbus RTU communications. The protocols should not be confused with an Ethernet interface. The manufacturer product description identifies a built-in basic operator panel (BOP) for configuration and local operation. The drive includes 4 standard digital inputs, 2 digital outputs (one relay changeover and one transistor), 2 analog inputs, and 1 analog output according to the exact datasheet. Confirm terminal electrical characteristics and communications wiring in the manual before integrating a PLC or an HMI. Optional accessories, software and licenses are not assumed to be included.

EMC Filter and Braking

The CV0 suffix of this exact order number designates the filtered version. Its datasheet states an integrated Class A EMC filter; Siemens commercial descriptions also refer to C3. Those labels come from different descriptions of EMC compliance and should be interpreted according to the installation environment and EN 61800-3 requirements. An integrated braking chopper is explicitly confirmed for 6SL3210-5BE32-2CV0. A separate external braking resistor is not stated as included. For high-inertia or rapid-deceleration systems, select and engineer any required resistor according to Siemens-approved specifications.

Mechanical and Environmental Considerations

The inverter uses frame size FSE, with nominal dimensions of 245 × 264.5 × 209 mm (W × H × D) and IP20 / UL open-type protection. External fan cooling is specified. The manufacturer lists installation altitude up to 1,000 m as a standard environmental condition, maximum operating relative humidity of 95%, and ambient operating temperature from −10 to 60 °C with temperature-dependent derating above 40 °C. Provide the required protective enclosure, clearances, ventilation, earthing and circuit protection. Siemens lists maximum motor cable lengths of 50 m shielded and 100 m unshielded; other EMC or application limits may be more restrictive.

Typical Applications and Selection

With its two duty configurations, this drive can be considered for appropriately sized pumps, fans, ventilation systems, conveyors and other industrial variable-speed loads. LO is appropriate only when the application meets its lower transient-overload requirement; HO provides a different continuous power and higher overload capability. Application recommendations are engineering suggestions, not guaranteed suitability for any particular machine. Confirm motor characteristics, acceleration/deceleration requirements, plant voltage, braking energy, and the applicable safety architecture before procurement or installation.

Exact Variant Identification

The complete manufacturer identifier 6SL3210-5BE32-2CV0 is essential. Do not substitute the unfiltered 6SL3210-5BE32-2UV0 when integrated EMC filtering is a requirement. Likewise, do not transfer ratings or physical dimensions from the adjacent 18.5 kW HO / 22 kW LO models. The CV0 unit is documented with an integrated braking chopper despite being an older revision. Installed accessories, compliance constraints and lifecycle information must be checked for the exact order code.
