Siemens SINAMICS V20 7.5 kW 3-Phase VFD 6SL3210-5BE27-5CV0

Electrical Ratings

The 6SL3210-5BE27-5CV0 is a Siemens SINAMICS V20 basic converter for speed control of compatible three-phase asynchronous motors. Its nominal rated motor capacity is 7.50 kW at 400 V IEC, while Siemens lists 10.00 HP at 480 V NEC. These are manufacturer-specific ratings, not a generic horsepower conversion. It is a three-phase input drive, not suitable for direct connection to single-phase supply. The nominal input is 380–480 V AC with a permitted −15%/+10% supply tolerance and 47–63 Hz line frequency. Output is three-phase AC with 400 V IEC / 480 V NEC rated voltage bases. A compatible motor must be selected by nameplate voltage, current, frequency, insulation and load requirements. The manufacturer’s output frequency range is 0–550 Hz, but motor and machinery speed limits must be respected.

Rated Current and Overload

The Siemens datasheet specifies 16.50 A rated output in both Low Overload (LO) and High Overload (HO) duty, including at the stated 480 V rating basis. Low Overload provides 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. These values describe temporary overload capacity, not continuous output above 16.50 A. Do not assume that an operating profile qualifies for a given duty classification without checking the actual machine load, acceleration, ambient temperature, cooling and permitted derating. The datasheet states derating considerations at temperatures of 40 °C or above.

Drive Control and Performance

The SINAMICS V20 series is intended for practical variable-frequency operation of industrial motors. The manufacturer identifies a built-in basic operator panel (BOP) and parameter-based setup. Appropriate ramping, speed references and protective parameters must be commissioned to the connected motor and load. The stated 0–550 Hz inverter output is a device capability and must not be taken as authorization to operate a motor or mechanical system at that speed. Model-specific closed-loop encoder control or servo positioning is not verified and should not be assumed. For precise control options and functional restrictions, consult the applicable Siemens operating instructions.

Communication and Configuration

Siemens confirms USS and Modbus RTU communication for this part number. These are serial communication protocols; the presence of a communication connector alone does not establish native Ethernet, PROFINET or other network protocols. The product listing specifies four digital inputs, two digital outputs, two analog inputs and one analog output. The built-in BOP permits local commissioning and operation according to the manufacturer’s procedures. Network wiring, address settings, baud rates and register handling should be checked in the official operating instructions. Any optional communications hardware must be verified and purchased separately where applicable.

EMC and Braking

This exact CV0 part number has an integrated EMC filter. Siemens’ ordering description calls it C3, while the exact-part datasheet describes the integrated filter as Class A; the two labels are recorded with their respective manufacturer source contexts. The datasheet explicitly says ‘With integrated braking chopper: Yes’ for 6SL3210-5BE27-5CV0. This is important because some smaller CV0 variants do not contain a braking chopper. An integrated chopper does not mean that a braking resistor is supplied. Any external resistor must be independently selected for resistance, continuous and pulse power, thermal safety and wiring requirements. Filter integration does not by itself guarantee EMC compliance of an installed machine; cable routing, grounding and installation remain important.

Mechanical Installation and Environment

The drive uses the FSD frame and has nominal dimensions 240.0 mm wide, 206.5 mm high and 172.5 mm deep. It is an IP20 / UL open-type device, requiring an appropriately designed electrical enclosure when site conditions demand additional protection. Siemens lists external fan cooling, mounting by through-hole/wall/side-by-side methods, 1,000 m installation altitude, and an operating temperature envelope of −10 to 60 °C with applicable derating. Its maximum specified relative humidity is 95%, and listed maximum motor cable lengths are 25 m shielded and 50 m unshielded. Enclosure airflow, protective grounding, circuit protection and cooling clearances must follow the Siemens manual.

Typical Applications

Potential applications include appropriately sized conveyors, pumps, fans, mixers and other industrial machines using compatible three-phase asynchronous motors. Selection depends on torque demand and acceleration time rather than matching motor kW alone. Where dynamic deceleration is needed, the integrated braking chopper may allow a properly rated external braking resistor, subject to Siemens’ component and installation requirements. A system integrator should confirm motor current and voltage, enclosure conditions, site EMC requirements, electrical protection and external control interfaces. Application examples are engineering suggestions rather than a guarantee of suitability for a particular machine.

Exact Variant and Lifecycle

The full manufacturer article number 6SL3210-5BE27-5CV0 identifies the original 7.5 kW, three-phase, filtered CV0 variant. Siemens identifies the successor as 6SL3210-5BE27-5CV1, with a different listed enclosure size. Do not treat the successor as mechanically interchangeable without reviewing drawings and terminal arrangements. The manufacturer lists a phase-out effective 19 August 2025. This workbook describes the exact CV0 version, not a neighboring power size or the successor. No price or stock information is included.
