Siemens SINAMICS V20 22 kW HO – 30 kW LO 3-Phase VFD 6SL3210-5BE32-2UV0

Overview

6SL3210-5BE32-2UV0 is a Siemens SINAMICS V20 basic frequency converter designed for variable-speed operation of suitable three-phase AC motors. The drive has a 380–480 V three-phase AC input, an IP20 / UL open-type enclosure and frame size FSE. This exact ordering variant is unfiltered; it must not be confused with the 6SL3210-5BE32-2CV0 model, which has an integrated EMC filter. The UV0 unit already includes a braking chopper, although an external braking resistor is a separate system component and is not confirmed as supplied.

Electrical Ratings

This converter is assigned two distinct operating duty ratings, rather than one interchangeable motor power. In High Overload (HO) duty it is rated for 22 kW at 400 V IEC (30 HP at 480 V NEC) with 45 A rated output current at 400 V and 40 A at 480 V. In Low Overload (LO) duty it supports 30 kW at 400 V IEC (40 HP at 480 V NEC), with rated output current of 60 A at 400 V and 52 A at 480 V. The supply is three-phase 380–480 V AC with documented −15% / +10% tolerance and 47–63 Hz input frequency. Three-phase output is nominally 400 V IEC or 480 V NEC, dependent on the supply and rating basis. Its output frequency range is 0–550 Hz; this does not establish that any connected motor can safely operate at that maximum speed.

Control Modes and Performance

The Siemens V20 family is intended for basic variable-speed control. For this exact order number, manufacturer ratings establish 110% of rated output current for 60 seconds in Low Overload mode, on a 300-second cycle, and 150% of rated output current for 60 seconds in High Overload mode, also on a 300-second cycle. Duty choice must follow the driven machine’s starting load, operating profile and thermal requirements. Avoid selecting on the 30 kW figure alone when an application requires the higher overload allowance of HO duty. The manufacturer datasheet specifies a 4 kHz pulse frequency and a 0–550 Hz output frequency range. Control mode and motor compatibility beyond the family’s basic converter function should be checked against the applicable V20 operating instructions before commitment.

Communication and Configuration

The manufacturer datasheet identifies USS and Modbus RTU as built-in communication protocols. The supplied operating description also identifies a built-in Basic Operator Panel (BOP) for parameterization and local operation. The standard I/O includes four digital inputs, two digital outputs (one relay changeover and one transistor), two analog inputs that may also be used as additional digital inputs, and one analog output. A protocol should not be confused with the connector carrying it. External gateways, communication devices and any optional accessories must be selected separately where needed; the datasheet does not confirm that such equipment is included.

Braking, EMC and Built-in Functions

The exact manufacturer datasheet explicitly states that the integrated filter class is “Unfiltered” and confirms an integrated braking chopper. Therefore a filtered drive must not be represented as equivalent to this UV0 version for EMC design. A braking chopper permits a suitable braking-resistor arrangement, subject to Siemens sizing and installation instructions; it does not mean an external resistor is included. Plan any required external EMC filtering, shielded cabling, earthing, protective equipment and enclosure design according to the actual installation. Consult the manufacturer for any safety-related functionality rather than treating common protective trips as certified safety functions.

Installation and Environmental Conditions

The Siemens datasheet identifies frame FSE and physical dimensions of 245 × 264.5 × 209 mm (width × height × depth). The enclosure is rated IP20 / UL open type and must be installed with appropriate protection against dust, moisture, accidental contact and environmental hazards. Mounting provisions documented for this drive include through-hole, wall and side-by-side mounting. The drive uses external fan cooling. The listed reference installation altitude is 1,000 m, and the operating-temperature range is −10 to 60 °C, subject to derating from 40 °C. Maximum relative humidity is 95%. Siemens lists maximum motor cable lengths of 50 m shielded and 100 m unshielded, subject to the relevant installation requirements.

Applications and Selection

Where electrical ratings, motor properties and machine demands are compatible, potential applications include industrial fans, pumps, conveyor drives, process auxiliaries, material handling and general production machinery. These are engineering suitability examples, not a claim of manufacturer approval for every installation. Confirm required speed range, acceleration/deceleration, torque demand, regeneration and braking duty, cooling, environmental conditions and EMC obligations. An application with a demanding start or mechanical overload should be assessed against the 22 kW HO / 45 A duty basis at 400 V rather than the 30 kW LO rating. Motor nameplate values and local electrical standards remain decisive for correct product selection.

Exact Variant Verification

The exact product identifier is 6SL3210-5BE32-2UV0. Siemens lists this model with unfiltered EMC hardware and an integrated braking chopper. The 6SL3210-5BE32-2CV0 is a different filtered ordering variant and must not be substituted in product content. Verify the delivered nameplate, intended voltage, 400 V versus 480 V current basis and duty selection before procurement and commissioning. The manufacturer datasheet also notes that published data may differ from rating-plate values. The 480 V current and HP ratings apply to the manufacturer-noted 440–480 V voltage range.
