Siemens SINAMICS V20 6SL3210-5BE21-5CV1 1.5 kW 3-Phase VFD

Product Overview

6SL3210-5BE21-5CV1 is a Siemens SINAMICS V20 basic frequency converter for adjustable-speed operation of compatible three-phase AC motors. This exact CV1 configuration has a rated motor capacity of 1.5 kW and is intended for a three-phase 380–480 V AC supply. Siemens specifies 4.10 A rated output current, an integrated EMC filter and an integrated braking chopper. It is a compact IP20 / UL open-type drive in frame size FSA. These specifications apply to this exact article number, not to other V20 frame sizes or older CV0 versions.

Electrical Ratings

The nominal rated input is 3 AC 380–480 V with the manufacturer-listed tolerance of −15% to +10%, at 47–63 Hz. The output is three-phase AC, with the Siemens datasheet referencing 400 V IEC and 480 V NEC rating bases. Rated motor power is 1.50 kW in both Low Overload and High Overload modes; Siemens also lists 2.00 hp on its NEC rating basis. The rated output current is 4.10 A for LO and HO. The manufacturer notes that output-current and HP data at the NEC basis apply across 440–480 V. Actual suitable motor selection requires checking the motor nameplate, load current, duty and operating environment.

The adjustable output frequency is 0–550 Hz. This describes the converter’s possible electrical-frequency setting, not a safe mechanical speed for a particular motor, gearbox or machine. Siemens lists 4 kHz as its pulse-frequency rating. Users should observe installation limits and relevant derating requirements rather than interpreting nominal ratings as unconditional for every environment.

Control Modes and Overload Performance

The exact-model datasheet differentiates duty classifications. Low Overload (LO) permits 110% of rated output current for 60 seconds within a 300-second cycle. High Overload (HO) permits 150% for 60 seconds within a 300-second cycle. Both modes show the same 1.50 kW motor-power and 4.10 A continuous output-current ratings for this model. These temporary overload limits do not increase the continuous current rating. Set protection parameters for the actual motor and process, and do not assume the higher temporary overload can be maintained continuously.

Communication and Operator Configuration

Siemens lists USS and Modbus RTU communications and a built-in Basic Operator Panel (BOP) for the V20 configuration. The product listing identifies four digital inputs, two digital outputs, two analog inputs and one analog output; the datasheet clarifies that the outputs consist of one relay changeover output and one transistor output. Two analog inputs can also serve as additional digital inputs according to the datasheet. Communication protocol support should not be confused with Ethernet connectivity or the inclusion of any optional module. Wiring, commissioning and parameter settings must follow Siemens operating instructions.

EMC Filter and Braking Configuration

This specific CV1 variant includes an integrated filter described as C3 in the Siemens product listing. Its technical datasheet describes the integrated filter as Class A. Those source terms describe the same exact-order-number filter from different document contexts and should not be extended to a blanket claim of compliance in every installation. Siemens explicitly confirms an integrated braking chopper for CV1. An external braking resistor is a separate item and is not confirmed as supplied with the converter. Braking performance depends on a correctly selected resistor and a suitable installation.

Installation and Environmental Considerations

The drive has an IP20 / UL open-type protection rating and normally requires an appropriate cabinet or protected mounting environment. The listed dimensions are 90 × 166 × 145.5 mm (width × height × depth), in frame FSA, with a listed net weight of 1.10 kg. Siemens states wall or side-by-side mounting and external fan cooling. The datasheet gives −10 to 60 °C operation subject to derating from 40 °C, and a reference installation altitude of 1,000 m. Review ventilation clearance, electrical protection, EMC wiring practices, shielding and cable limitations before integration.

Typical Applications and Selection

Appropriate applications may include motor-driven conveyors, pumps, ventilation fans, mixers and packaging auxiliaries where a compatible three-phase motor, required torque, operating cycle and site electrical supply have been verified. These are engineering-use examples, not guarantees that the converter fits every machine of that type. Applications with fast deceleration or high inertia may need a correctly engineered external braking resistor. Motor-control suitability, safety functions and accessory needs should be checked against the Siemens instructions and the complete machine design.

Exact CV1 Variant Verification

The full order code 6SL3210-5BE21-5CV1 identifies the 1.5 kW filtered CV1 revision. The earlier 6SL3210-5BE21-5CV0 is not identical: the later CV1 configuration expressly includes an integrated braking unit. The UV1 counterpart is an unfiltered variant. Never substitute another variant based only on matching power, size or V20 family membership. For replacement work, confirm the complete nameplate part number and the existing supply, filter, braking and terminal requirements.
