Siemens SINAMICS V20 6SL3210-5BB21-1BV1 1.1 kW 1-Phase VFD

Siemens SINAMICS V20 6SL3210-5BB21-1BV1 1.1 kW 1-Phase VFD

Overview

The Siemens SINAMICS V20 6SL3210-5BB21-1BV1 is a compact variable frequency drive for controlling the speed of compatible three-phase AC motors from a single-phase AC supply. Its 1.1 kW rating, 200–240 V AC nominal line supply, 6.00 A rated output and built-in basic operator panel make it relevant to small machine and building-service drives. This exact BV1 ordering variant contains an integrated Class B (C1) EMC filter; it should not be confused with the UV1 unfiltered variant. The official datasheet identifies the enclosure as IP20 / UL open type and its frame as FSAC.

Electrical Ratings

The drive accepts a single-phase AC input with nominal line voltage 200–240 V and a datasheet permitted tolerance of −15% to +10%; line frequency is 47–63 Hz. Its output is three-phase AC at an IEC nominal rating of 230 V, or 240 V under the NEC reference. The Siemens datasheet gives 1.1 kW (1.50 hp) for both Low Overload (LO) and High Overload (HO), under their respective IEC and NEC rating references. These figures must be considered together with the specified motor voltage and duty. The rated output current is 6.00 A in either duty classification. The datasheet states that NEC horsepower and current ratings apply at 220–240 V. Output frequency can be set within 0–550 Hz, subject to the motor and machinery limits. The stated pulse frequency is 8 kHz.

Control Modes and Performance

The SINAMICS V20 family is a basic converter designed for variable-speed motor control. For this exact part, Siemens documents Low Overload capability of 110% rated output current for 60 seconds in a 300-second cycle, and High Overload capability of 150% for 60 seconds in a 300-second cycle. Both are temporary overload capacities, not continuous current ratings. The Siemens catalogue confirms a built-in basic operator panel (BOP). Precise motor type and control-mode combinations should be checked against the applicable SINAMICS V20 operating instructions before specifying a nonstandard motor or control scheme.

Communication and Configuration

The exact-model Siemens datasheet identifies USS and Modbus RTU as communication protocols. The serial interface should be checked against the operating instructions when wiring. These are serial protocols; their presence does not imply Ethernet communication. The exact-model datasheet specifies four digital inputs, two digital outputs (one relay and one transistor), two analog inputs that may also be configured as digital inputs, and one analog output according to the exact-model Siemens datasheet. These I/O functions allow integration with suitable switches, sensors and controllers subject to electrical and parameter limitations. The built-in BOP supports local commissioning and parameter operation. Optional external panels or accessories, if needed, must be separately verified for compatibility; none should be assumed included.

Braking, EMC and Built-in Functions

The exact-model Siemens datasheet specifies an integrated Class B EMC filter, and the Siemens catalogue identifies the product as an integrated-filter C1 variant. Any application requiring a defined conducted-emission performance must assess the full installation, cabling and necessary external EMC measures. Siemens also specifies that this part does not have an integrated braking chopper. Do not treat an external braking resistor as included or presume that it can be directly connected for dynamic braking. If rapid stopping or high-inertia regeneration is required, consult the exact operating documentation and design an appropriate solution. Other onboard control functions should be configured only in accordance with the applicable V20 manuals.

Installation and Environmental Conditions

The FSAC enclosure dimensions are 91.0 × 160.9 × 147.0 mm (width × height × depth); the datasheet lists net weight of 1.40 kg. Siemens specifies external-fan cooling and wall or side-by-side mounting. Protection is IP20 / UL open type, so suitable enclosure protection is needed wherever dust, liquid or access hazards require more than that rating. The datasheet gives an operational ambient range of −10 to +60 °C and explicitly requires derating at 40 °C or above. The reference installation altitude is 1,000 m and maximum operating relative humidity is 95%. The specified motor-cable maximum is 25 m with shielded cable and 50 m with unshielded cable, subject to installation requirements. Observe grounding, protective devices, clearances and all manufacturer instructions.

Typical Applications

For compatible three-phase motors within the verified rating, potential uses include small pumps, ventilation fans, compact conveyors, agitators, feeders and other moderate-power speed-controlled machinery. These are technically appropriate application suggestions, rather than promises that every motor or load can be connected directly. Motor full-load current, starting torque, acceleration/deceleration demands, overload duty and the required EMC environment must all be checked. Heavy-inertia machines or aggressive deceleration requirements need particular attention because the drive has no integrated braking chopper.

Exact Variant Verification

The complete Siemens ordering code 6SL3210-5BB21-1BV1 identifies the 1.1 kW FSAC model with an integrated Class B/C1 EMC-filtered configuration. The nearby 6SL3210-5BB21-1UV1 order code is the unfiltered variant and its EMC characteristics must not be copied into this listing. Likewise, other power levels and earlier revisions can have different mechanical sizes and voltage tolerances. For procurement, replacement and installation, verify the full printed manufacturer order code and rating plate.
