Siemens SINAMICS V20 6SL3210-5BE23-0UV0 3 kW 3-Phase VFD

Siemens SINAMICS V20 6SL3210-5BE23-0UV0 3 kW 3-Phase VFD

The Siemens SINAMICS V20 6SL3210-5BE23-0UV0 is a compact 3.0 kW / 4 HP variable-frequency drive for three-phase motor-speed control on 380–480 V AC electrical supplies. It is the original UV0 unfiltered frame-size-B configuration. The drive offers integrated operator controls and serial communication through USS and Modbus RTU. Selection should be made against the exact motor current, duty cycle, braking demands and installation environment; the UV0 hardware is not interchangeable in specification with the UV1 or filtered CV variants.

Electrical Ratings

The 6SL3210-5BE23-0UV0 is rated for a 3.0 kW (4 HP) motor in the manufacturer’s high-overload and low-overload categories. It requires a three-phase 380–480 V AC supply, with a specified tolerance of −15%/+10%, and 47–63 Hz input frequency. Its three-phase nominal output voltage is 400 V AC, with 7.30 A rated output current in both duty categories. Siemens’ converter selection table records a rated input current of 8.6 A and 7.3 A output at 480 V under the documented 4 kHz/40°C basis. The output frequency range is 0–550 Hz. Supply, motor nameplate, protective devices, and installation conditions must be checked together before selection.

Control Modes and Performance

The SINAMICS V20 is designed for adjustable-speed motor control in general industrial drive systems. Its supported control and commissioning functions include V/f control and configurable acceleration/deceleration ramps, with parameter settings chosen to suit the machine. Siemens rates Low Overload (LO) at 110% of rated output current for 60 seconds with a 300-second cycle, and High Overload (HO) at 150% for 60 seconds with a 300-second cycle. The overload figures are temporary allowances, not continuous output ratings. Actual motor suitability depends on its nameplate current, cooling, duty profile, load torque, and permissible operating speed.

Communication and Configuration

This variant supports USS and Modbus RTU fieldbus communication. Siemens identifies the built-in basic operator panel (BOP) for parameter entry, local operation, and commissioning. The drive has 4 digital inputs, 2 digital outputs, 2 analog inputs and 1 analog output according to the Siemens product description. Communication protocol support should not be confused with an Ethernet interface or with optional fieldbus adapters. External controller compatibility depends on wiring, addressing, baud rate, serial interface details, and implemented command mappings.

Braking EMC and Built-in Functions

The exact UV0 article is the unfiltered version, without an integrated EMC filter. Installation may need external interference-suppression measures and appropriate shielded wiring according to applicable site requirements. Unlike the UV1 successor, the UV0 product description does not include an integrated braking unit; the older UV0 configuration must not be sold as having an integrated braking chopper. For an application that needs rapid deceleration or regenerative energy management, verify a supported external solution and its installation instructions rather than assuming that a braking resistor can simply be connected. No external resistor is established as included.

Installation and Typical Applications

The converter has an IP20 / UL open-type enclosure and frame size B (FSB), with catalogue envelope approximately 140 × 160 × 165 mm (W × H × D). The manufacturer describes fan cooling and a general operating temperature span of −10 to 60°C, subject to applicable derating and installation requirements. Install the drive in an appropriate electrical enclosure with adequate ventilation, protective earthing, cable routing, and clearance. Practical applications can include fans, pumps, conveyors, mixers and general machinery where the motor current, torque demand and load characteristics are compatible. Applications involving severe braking, safety-rated stopping, or special motor technologies require separate engineering verification.

Exact Variant Verification

This workbook is specific to Siemens article 6SL3210-5BE23-0UV0: a 3 kW, three-phase 380–480 V AC, unfiltered SINAMICS V20 in frame size B. The filtered 6SL3210-5BE23-0CV0 and the later unfiltered 6SL3210-5BE23-0UV1 are different order variants. The UV1 successor is described by Siemens as having an integrated braking unit; its hardware must not be silently transferred to UV0. Siemens documentation identifies the UV0 generation in a phase-out transition; verify current lifecycle status on the exact article page before procurement. The datasheet link below is the official manufacturer documentation endpoint but direct full-page retrieval may be restricted.
