Siemens SINAMICS V20 6SL3210-5BB21-1UV1 1.1 kW 1-Phase VFD

Product Overview

The Siemens SINAMICS V20 6SL3210-5BB21-1UV1 is a basic variable-frequency drive for controlling a compatible three-phase AC motor from a single-phase low-voltage supply. This exact 1.1 kW variant provides a rated output current of 6.00 A and has an unfiltered configuration. Its compact FSAC construction, integrated basic operator panel and standard serial communication make it suitable for straightforward speed-control tasks. The equipment is an industrial motor drive, not a motor or a complete drive-and-motor package.

Electrical Ratings

The manufacturer lists 1.10 kW and 1.50 hp for both Low Overload (LO) and High Overload (HO) classifications. It takes 1 AC, nominal 200–240 V supply at 47–63 Hz and provides a three-phase output with a nominal 230 V IEC rating (240 V NEC rating). The exact-model datasheet specifies 200–240 V with -15%/+10% tolerance; the Siemens Industry Mall summary instead states -10%/+10%. Confirm permitted supply conditions against the product nameplate and applicable installation documentation. The continuous output rating is 6.00 A in both LO and HO. The output frequency setting range is 0–550 Hz; this does not imply that every connected motor or mechanical system can safely run at the maximum frequency.

Control Modes and Performance

The official exact-part documentation distinguishes Low Overload from High Overload. LO permits 110% of rated output current for 60 seconds within a 300-second cycle. HO permits 150% for 60 seconds within a 300-second cycle. These are temporary overload capabilities, not continuous-current ratings. Exact control-algorithm options and compatible motor technologies should be checked in the current V20 operating instructions before commissioning; no unsupported closed-loop or permanent-magnet compatibility claim is made here.

Communication and Configuration

The drive includes USS and Modbus RTU communications, as described in Siemens’ product information. Its built-in basic operator panel (BOP) supports local operation and parameter access. Manufacturer-listed I/O includes four digital inputs, two digital outputs, two analog inputs and one analog output. Configuration of the integrated serial interface, control terminals and application parameters must follow Siemens documentation. No Ethernet, PROFINET or optional communication module is assumed to be supplied.

Braking, EMC and Built-in Equipment

This 6SL3210-5BB21-1UV1 variant has no integrated EMC filter and no integrated braking chopper, according to the exact-model datasheet. It must not be substituted in a design requiring an integral Class B/C1 EMC filter without separately addressing the EMC installation. No braking resistor or external braking component is represented as included. External line-side or load-side components, when required, need separate engineering selection.

Installation and Operating Conditions

Siemens identifies an FSAC frame, IP20 / UL open-type protection and mounting on a wall or side by side. The exact datasheet gives dimensions of 91.0 × 160.9 × 147.0 mm (width × height × depth), external-fan cooling, and a reference installation altitude of 1,000 m. Listed operating ambient is -10 to +60 °C, with derating required at 40 °C and above. Maximum motor-cable lengths given in the datasheet are 25 m shielded and 50 m unshielded; installation-specific EMC requirements may impose other limits. IP20 is not a weatherproof or washdown enclosure rating.

Typical Applications

Where the motor, load, supply and environment are compatible, a 1.1 kW V20 may be considered for modest fans, pumps, conveyors, mixers or other basic adjustable-speed machinery. These are engineering suitability examples, not guarantees of compatibility or Siemens’ model-specific application certifications. Verify acceleration, overload, protective coordination, emergency-stop design and any braking requirements for the actual machine.

Exact Variant Verification

The complete part number is 6SL3210-5BB21-1UV1. Its suffix UV1 identifies the unfiltered configuration discussed here, rather than the corresponding filtered BV1 version. Ratings, frame and dimensions should not be carried across generations or differently coded models. The exact-model Siemens datasheet and product listing are the primary references, with their different supply-tolerance descriptions recorded for review.
