1 Selection of frequency converter Usually the size of frequency converter is chosen on the basis of the shaft output, as this may be the only value known. However, if the data are known for both the application, the motor and the frequency converter, it is recommended to make a more accurate sizing. The values must be based on the rated motor speed. VLT 2000 only operates according to the CT (constant torque) characteristic Sizing on the basis of the apparent power S M [kva] consumed by the motor Exercise A motor must yield constant torque at continous operation. Usually the necessary values will appear from the motor plate or from the motor catalogue. Solution From the table on the next page you can see that VLT type 2025 can yield 2.0 kva (415 V) at continuous operation. The solution is therefore VLT type Sizing when you know the motor current Exercise Conveyor plant with a 1.1 kw, V motor. At continuous operation the motor current is 2.5 A ( V). Solution From the table on the next page you can see that a VLT type 2025 can yield 2.8 A at continuous operation. The right solution is therefore VLT Read values Motor current = 2.5 A (3 415 V) s M = U I [kva] = [kva] 1000 = 1.8 kva Sizing on the basis of the power requirement P VLT [kw] of the motor Exercise A machine tool is driven by a 3 kw motor. The power requirement is indicated to be 2.4 kw. The motor efficiency η is 0.80, cos ϕ = 0.81 and the motor voltage is 3 x 415 V. η and cos ϕ are measured at 3 kw output. We estimate η and cos ϕ to be approximately the same at 80 % load. Solution From the table on the next page you can see that VLT type 2040 can yield 4.0 kva (415 V) at continuous operation. The right solution is therefore VLT type S VLT = P m η cos ϕ = 2.4 kw = 3.7 kva 30 MG.20.B6.02 VLT is a registered Danfoss trademark

3 Product range The VLT 2000 Series is available in a single-phase/ three-phase version (1 x V or 3 x V) in the power range kw and a three-phase version (3 x V) in the power range kw. A three-phase version (3 x V) in the power range kw is also available. All units are delivered in an IP 20 enclosure. How to find the right code number When you have found the right VLT size you can find the code number to be ordered in the table below. Example: VLT type 2020 (3 x V) three-phase without display with brake has the code number 195H3400.
