Siemens SINAMICS V20 6SL3210-5BB21-5BV1 1.5 kW 1-Phase VFD

Siemens SINAMICS V20 6SL3210-5BB21-5BV1 1.5 kW 1-Phase VFD

The Siemens SINAMICS V20 6SL3210-5BB21-5BV1 is a compact variable frequency drive intended for adjustable-speed control of compatible three-phase induction motors from a single-phase AC supply. This exact ordering variant is rated for a 1.5 kW motor and is identified in Siemens documentation as the filtered version with an integrated C1 EMC filter. Its FSAC construction uses external fan cooling and provides an IP20 / UL open-type enclosure. The drive supports local operation, terminal control and serial fieldbus communication for integration into basic industrial motor-control systems. The precise motor nameplate, loading and enclosure conditions should always be checked before selection.

Electrical Ratings

This converter accepts a single-phase 200–240 V AC mains supply at 47–63 Hz. Siemens’ exact-part datasheet states a -15% / +10% voltage tolerance, while catalogue-style product descriptions can state -10% / +10%; the difference is documented in the verification area. The rated input current given in Siemens’ converter variant table is 19.7 A. The output is three-phase AC with a nominal IEC output-voltage designation of 230 V and a motor rating of 1.5 kW. The continuous rated output current is 7.8 A under the manufacturer-rated conditions. The adjustable output-frequency range is 0–550 Hz; this is an electronic drive range, not a universal permissible motor or machine operating speed.

Control Modes and Performance

The SINAMICS V20 platform supports V/f control and related V/f characteristic options for speed control of suitable induction motors. Selection and parameterization must reflect the driven machine and motor requirements. Siemens identifies a 150% high-overload capacity for 60 seconds, subject to its stated duty cycle and installation conditions, and a 110% low-overload capacity for 60 seconds where that duty classification is supported. The latter figures are temporary capacity limits, not continuous rated output currents. Motor performance, output-current derating, motor cooling and thermal protection all require attention during commissioning.

Communication and Configuration

The unit provides integrated USS and Modbus RTU communication via an RS-485 interface, as described by Siemens for the V20 family. RS-485 identifies the physical interface; USS and Modbus RTU identify the supported serial protocols. The basic operator panel (BOP) is built in and supports parameter setting, commissioning and local operation. Digital and analog input/output terminals enable conventional start/stop, reference and status connections. Optional communication accessories, remote panels or extension equipment, where applicable, must be checked against the current Siemens option documentation and are not presumed supplied.

Braking, EMC and Built-in Functions

The BV1 ordering suffix identifies the integrated filtered version. Siemens’ product descriptions specify an integrated C1 EMC filter; achieving applicable EMC performance also depends on compliant installation, grounding, shielded wiring and motor-cable lengths. A braking chopper is not integrated into this FSAC unit; do not assume that an external braking resistor can be connected directly or that a resistor is supplied. For loads with appreciable regeneration or rapid deceleration needs, Siemens-approved external braking arrangements should be assessed. The drive provides parameterized acceleration/deceleration, protective functions and basic motor-control features; these are not a substitute for separately engineered machine safety functions.

Installation and Typical Applications

The FSAC chassis is designed for wall or side-by-side cabinet mounting and uses an external fan. Siemens lists an IP20 / UL open-type construction and an operating-temperature envelope up to 60 °C, with derating or other restrictions depending on temperature, altitude, installation and loading. The datasheet identifies 1,000 m as the base installation altitude and gives maximum motor-cable lengths of 25 m shielded and 50 m unshielded, subject to installation conditions. Typical speed-control tasks may include appropriately sized fans, pumps, conveyor drives, blowers and simple machinery, provided the motor, current profile, overload and braking requirements fit. Suitability for an individual application is an engineering selection, not an automatic guarantee.

Exact Variant Verification

This workbook refers specifically to 6SL3210-5BB21-5BV1: a 1.5 kW filtered SINAMICS V20 with single-phase 200–240 V input and a 7.8 A output rating. It must not be confused with 6SL3210-5BB21-5UV1 (unfiltered 1.5 kW), 6SL3210-5BB21-1BV1 (filtered 1.1 kW), or older AV0 revisions with different frames or EMC categories. Confirm the full nameplate article number during procurement and replacement.
