Siemens SINAMICS V20 6SL3210-5BE15-5CV1 0.55 kW 3-Phase VFD

Siemens SINAMICS V20 6SL3210-5BE15-5CV1 0.55 kW 3-Phase VFD

The Siemens SINAMICS V20 6SL3210-5BE15-5CV1 is a compact variable frequency drive for adjustable-speed control of suitably rated industrial AC motors. This exact CV1 variant is a 0.55 kW unit for three-phase 380–480 V AC mains and includes an integrated C3 EMC filter and an integrated braking unit. Siemens identifies it as an IP20 / UL open-type drive in frame size FSA. It replaces the previous CV0 part, and the braking hardware is an important ordering distinction.

Electrical Ratings

This inverter accepts three-phase AC supply with a nominal range of 380–480 V, with a stated supply tolerance of −15%/+10%, and line frequency of 47–63 Hz. Rated motor power is 0.55 kW. The published rated output current is 1.70 A; output is three-phase, with nominal output voltage associated with the applied supply and regional IEC/NEC ratings. The manufacturer specifies a programmable frequency range up to 550 Hz. The maximum drive frequency should not be interpreted as a permissible operating speed for any particular motor or mechanical load. Motor nameplate data and drive parameters must match before commissioning.

Control Modes and Overload Performance

The SINAMICS V20 family provides adjustable-frequency motor control, including voltage/frequency-based operation and application-oriented functions documented in the operating instructions. Siemens advertises a 150% overload capability for 60 seconds for this particular article. Its detailed technical documentation distinguishes high-overload (HO) and low-overload (LO) duty, typically 150% and 110% for 60 seconds respectively, each based on a 300-second cycle. The overload limits must be applied with the correct duty selection, rated current, ambient temperature, switching frequency, and applicable derating. They are temporary capacities, not continuous output ratings.

Communication and Configuration

The exact Siemens listing identifies USS and Modbus RTU fieldbus communication, alongside the integrated Basic Operator Panel (BOP). It also lists four digital inputs, two digital outputs, two analog inputs and one analog output. Physical wiring and terminal functions should be checked in the corresponding installation manual before connecting a PLC, controller or operator interface. Protocol support is not equivalent to Ethernet, and no Ethernet functionality is claimed here. Other communication adapters or external options are not assumed to be fitted.

EMC Filter and Braking

The CV1 variant has an integrated EMC filter designated C3 in the Siemens product listing. The datasheet may use Class A terminology for its EMC-filter description; these labels come from different classification contexts and should not be silently treated as interchangeable certification statements. This particular model also has an integrated braking unit, unlike the earlier 6SL3210-5BE15-5CV0. The integrated braking hardware does not mean that a braking resistor is supplied. Any resistor, duty-cycle allowance and protective wiring must be selected according to Siemens documentation.

Installation and Protection

The enclosure protection is IP20 / UL open type and is intended for installation with suitable protection against contact, dust and environmental exposure. Siemens specifies FSA dimensions of 90 × 150 × 145.5 mm (width × height × depth). The drive is convection cooled. Manufacturer data identify operation up to 60 °C subject to temperature derating above 40 °C, and a typical installation altitude basis of 1,000 m. Allow required ventilation clearances and observe derating and cable-length recommendations. The integrated EMC filter alone does not guarantee installation-level EMC compliance; grounding, shielding and routing still matter.

Applications

Within its electrical and thermal limits, the drive is suited to adjustable-speed duty such as small conveyors, fans, pumps, material-handling feeders, and general machinery powered by compatible AC motors. Application suitability depends on starting torque, load inertia, braking energy, ambient conditions, and protective components. For applications with frequent deceleration, engineers must verify whether an approved external braking resistor is needed. A single rated-power value is not proof of compatibility with a specific motor or machine.

Exact Variant Verification

The complete part number 6SL3210-5BE15-5CV1 identifies the three-phase 380–480 V, 0.55 kW filtered successor design. It must not be confused with unfiltered 6SL3210-5BE15-5UV1 or with the older filtered CV0 generation. Siemens explicitly describes the CV1 with an integrated braking unit; the corresponding CV0 product description omits that feature. Do not substitute product photographs, performance data, wiring assumptions or braking accessories from another part-number suffix.
