Siemens 6SL3210-5BE31-8UV0 SINAMICS V20 Frequency Inverter
The Siemens 6SL3210-5BE31-8UV0 (also referenced as 6SL32105BE318UV0) is a SINAMICS V20 series frequency converter. It is designed for basic variable speed drive applications with single-phase AC input (200-240 V) and three-phase output up to 1.8 kW (2.4 hp). The V20 drive is known for its robustness, simple commissioning, and energy saving features.
Electrical Ratings
Input: 1 AC 200-240 V, 50/60 Hz, current 11.9 A typical. Output: 3 AC 0-240 V, 0-599 Hz, rated current 8.8 A, overload capability 150% for 60 seconds. Power loss: 38 W typical. Efficiency: >96% at rated load. The drive includes an integrated Class A EMC filter (optional disconnection via jumper).
Control and I/O
Control modes: V/f (linear, multi-point, square), V²/f. The drive features a built-in PID controller for pressure, flow, or temperature regulation. I/O: 4 digital inputs (sink/source, 24 V DC), 1 analog input (0-10 V or 0-20 mA), 1 relay output (NO, 250 V AC/3 A), and 1 analog output (0-20 mA). An optional fieldbus module can be added for PROFIBUS, PROFINET, or Modbus RTU (RS485).
User Interface and Commissioning
The drive comes with a detachable basic operator panel (BOP) with a 4-digit, 7-segment LED display and 5 buttons for parameterization. Parameters are organized in two levels: standard (access to common parameters) and expert. The SINAMICS V20 supports quick commissioning via a setup wizard. A free PC tool (SINAMICS V20 Smart Access) allows wireless commissioning via a web browser when using a separate web server module.
Mechanical and Environmental
Dimensions (W x H x D): 95 mm x 189 mm x 119 mm. Weight: 1.5 kg. Mounting: DIN rail (EN 60715) or screw-mount back plate. Operating temperature: -10°C to 50°C (derate above 40°C). Storage: -40°C to 70°C. Protection rating: IP20. The drive withstands vibration 0.3 g (10-55 Hz). It is coated for humidity resistance (class 3K3 per EN 60721-3-3).
Applications and Benefits
Typical applications include fans, pumps, conveyors, and mixers. The energy saving features include automatic energy optimization (for V/f control) and sleep mode (for pumps). The drive stores the last 4 faults and alarms in a logbook. Integrated braking chopper allows connection of an external braking resistor for rapid deceleration.
