Siemens SINAMICS V20 11 kW 3-Phase VFD 6SL3210-5BE31-1CV0

6SL3210-5BE31-1CV0 is a Siemens SINAMICS V20 basic AC variable frequency drive designed for adjustable-speed operation of a correctly matched three-phase electric motor. This exact CV0 order number identifies an 11.00 kW drive for a 380–480 V AC three-phase supply. The Siemens datasheet specifies a 25.00 A rated output at the 400 V IEC rating and 21.00 A at the 480 V NEC rating. It has an integrated Class A EMC filter, built-in USS and Modbus RTU communication, an integrated braking chopper and an IP20 / UL open-type enclosure. These details identify the exact product and should not be transferred from other V20 power classes or revisions.

Electrical Ratings

The supply requirement is three-phase 380–480 V AC, with Siemens specifying a −15%/+10% tolerance and a 47–63 Hz line-frequency range. The output is three-phase AC with 400 V IEC and 480 V NEC reference ratings. Both Low Overload (LO) and High Overload (HO) power ratings are 11.00 kW, and Siemens lists 15.00 HP at the NEC reference voltage. The rated output current for each duty classification is 25.00 A at 400 V or 21.00 A at 480 V. The 480 V output-current and horsepower ratings must not be interpreted as universal ratings across all supply voltages. The output frequency range is 0–550 Hz. This range is a drive capability, not a statement that any motor or machinery may safely run at its upper limit.

Control Modes and Performance

The V20 is a variable-frequency converter intended to regulate motor speed through its configured output frequency and voltage. The official exact-part datasheet lists Low Overload capability at 110% of rated output current for 60 seconds within a 300-second cycle. It independently lists High Overload capability at 150% for 60 seconds within a 300-second cycle. The identical nominal motor power and currents in both rating columns do not make their permissible overload profiles interchangeable. Motor selection must consider duty cycle, machine load, permitted motor frequency, and operating temperature. A 4 kHz pulse frequency is included in Siemens’ rated data; actual operating settings should follow installation and commissioning documentation.

Communication and Configuration

Integrated communications listed in the Siemens datasheet are USS and Modbus RTU. These are communication protocols; a specific physical network connection or Ethernet capability must not be assumed solely from the protocol names. Siemens’ product family is equipped with local basic operator controls for drive setup and operation, but commissioning must follow the relevant V20 operating instructions. The exact-part datasheet specifies four digital inputs, one relay changeover digital output, one transistor digital output, two analog inputs that may also be configured as additional digital inputs, and one analog output. No optional communication board is claimed as included with this model.

Braking, EMC and Built-in Functions

A particularly important feature of this 11 kW CV0 drive is its integrated braking chopper. Siemens explicitly states this in the exact-part datasheet. The chopper must be distinguished from an external braking resistor, whose supply or inclusion is not established by that document. A suitable external resistor, if required for an application, must be selected and installed according to Siemens instructions and the energy involved. The integrated EMC filter is specified as Class A; the Siemens catalog discusses C3 application conditions for industrial-environment filtered V20 configurations. Actual EMC conformity also depends on cable lengths, shielding, earthing, installation and applicable conditions. Do not interpret the filter as unconditional residential-environment compatibility.

Installation and Typical Applications

The converter uses an FSD enclosure of 240.0 mm width, 206.5 mm height and 172.5 mm depth, with IP20 / UL open-type protection. Siemens specifies external-fan cooling, up to 1,000 m installation altitude without applying additional high-altitude requirements from the manual, and a documented operating range of −10°C to 60°C with derating at 40°C and above. The datasheet lists maximum motor-cable lengths of 25 m shielded and 50 m unshielded; compliance with the integrated filter’s emission conditions can impose stricter limits. Wall, through-hole and side-by-side mounting methods are listed, subject to thermal and mechanical instructions. Technically appropriate applications can include pumps, fans, conveyors, mixers and material handling where motor current, overload requirements, thermal conditions and required stopping performance are verified.

Exact Variant Verification

The complete order number 6SL3210-5BE31-1CV0 must be used when matching the unit, documents and replacements. It identifies the 11 kW integrated-filter CV0 version, not an unfiltered UV0 drive or another voltage class. The exact Siemens datasheet states an integrated braking chopper for this model; do not assume the braking arrangements of smaller CV0 variants apply here. Similarly, differences in rated output current between 400 V and 480 V operation must be preserved in product selection. Frame size FSD and the listed physical dimensions matter for cabinet fit and replacement planning.
