Siemens SINAMICS V20 6SL3210-5BB11-2UV1 0.12 kW 1-Phase VFD

Siemens SINAMICS V20 6SL3210-5BB11-2UV1 0.12 kW 1-Phase VFD

The Siemens SINAMICS V20 6SL3210-5BB11-2UV1 is a compact variable frequency drive (VFD) for speed control of suitable three-phase asynchronous motors from a single-phase 200–240 V AC supply. This exact 0.12 kW converter is the unfiltered FSAA variant, not the separately ordered filtered 6SL3210-5BB11-2BV1. Its 0.9 A rated three-phase output and integrated operator panel make it a practical choice for small motor-driven equipment where the motor nameplate, supply and load duty are compatible.

Electrical Ratings

This model accepts one-phase 200–240 V AC nominal line supply at 47–63 Hz. Siemens lists 2.3 A rated input current and 0.9 A rated output current at 0.12 kW. Its output is three-phase AC, with output voltage dependent on the input supply, not an independent higher-voltage source. The Siemens datasheet specifies 0–550 Hz output frequency; this is a converter capability, not permission to exceed the motor or machine speed rating. Confirm the permissible input tolerance from the applicable revision of the Siemens datasheet; published product descriptions sometimes summarize it differently. The output-current and horsepower rating conditions noted by Siemens apply at 220–240 V.

Control Modes and Performance

SINAMICS V20 provides voltage/frequency-based motor speed control with selectable characteristics and motor-control settings documented in the V20 operating instructions. Siemens lists 150% rated output current for 60 seconds under high-overload duty, with a 300-second cycle; low-overload operation is specified at 110% for 60 seconds per 300-second cycle. These are temporary overload limits, not continuous 1.35 A operation. Drive settings, thermal limits, load characteristics and the controlled motor must all be assessed before commissioning.

Communication and Configuration

Built-in USS and Modbus RTU serial communication are documented for this V20 variant. These are protocols; their presence should not be confused with Ethernet or optional network protocols. The drive has a built-in Basic Operator Panel (BOP) for local commissioning, parameter editing and operation. Its standard I/O includes four digital inputs, two digital outputs, two analog inputs and one analog output according to Siemens V20 documentation. External controllers must use a compatible physical connection and correctly configured serial settings. Check the operating manual for wiring and communication parameters.

Braking, EMC and Built-in Functions

This part number is expressly unfiltered: no integrated EMC filter should be assumed. Siemens also identifies no integrated braking chopper for the exact model. Do not treat an external braking resistor as supplied, or assume a resistor alone can be connected for dynamic braking. Siemens V20 documentation describes general drive functions such as ramp adjustment, PID control and energy-related control features at family level; activation and suitability depend on parameters and application requirements. Any external filter or braking solution requires separate selection and confirmation against approved manufacturer instructions.

Installation and Motor Compatibility

The converter uses the compact FSAA fanless construction, with convection cooling and IP20 / UL open-type protection. Siemens gives dimensions 68 × 142 × 107.8 mm (W × H × D) and permits wall or side-by-side mounting under stated installation rules. Operation is specified from -10 to 60 °C with derating above 40 °C; installation altitude is specified at 1,000 m before applicable derating considerations. Siemens lists maximum motor cable lengths of 25 m shielded and 50 m unshielded under stated conditions. Install inside a suitable protective enclosure as needed and follow grounding, clearances, wiring and overcurrent-protection instructions. Siemens documentation allows suitably selected standard third-party asynchronous motors; the motor insulation and electrical ratings must be compatible with converter duty.

Typical Applications

For a correctly sized 0.12 kW motor, possible uses include miniature conveyors, small fans, metering mechanisms, light-duty feeders, compact mixers and laboratory or packaging auxiliaries. These are engineering application examples rather than guaranteed manufacturer approvals for every machine. Check starting and running torque, duty cycle, deceleration energy, environment and required protective functions. Applications demanding highly dynamic braking, integrated safety functions or additional communication hardware may require a different drive or external equipment.

Exact Variant Verification

The order number 6SL3210-5BB11-2UV1 identifies the 0.12 kW, single-phase 230 V-class, unfiltered FSAA variant. The closely related 6SL3210-5BB11-2BV1 is a filtered model, while 6SL3210-5BB11-2UV0 belongs to an older configuration and must not be substituted when verifying dimensions or revisions. Use the exact order number on the drive rating plate when ordering or planning replacements.
