There are several basic criteria that will help you choose the optimal model. It will provide the necessary technical and operational parameters.

Depending on the control method First of all, it is necessary to exclude models that do not correspond to the required power, type of execution or overload properties. Depending on the control method, two types can be distinguished: scalar and vector. In modern models, the second option is mainly used, but the cost of such a converter is slightly higher than with a scalar mode. Among its features, you can identify the possibility of more accurate implementation of the tasks, while significantly reducing the likelihood of a static error. The advantage of the scalar mode is to maintain the established ratio of frequency and output voltage. According to the power level. If the equipment has the same level of power, experts recommend choosing converters of the same manufacturer. The power is determined from the maximum load level. Such an approach will allow to provide the interchangeability of equipment necessary for effective work and greatly facilitate its servicing.

For mains voltage When selecting equipment it is better to give preference to a model with a wide voltage range. As otherwise, a decrease in this indicator may lead to equipment shutdown, and when the device is raised, the device may fail or the electrolytic capacitors.

Over the range of controlled frequency In the process of using an engine with a high level of nominal frequency, it is better to choose in favor of a converter with an upper limit of this parameter. It is important to make sure that its range meets the specific requirements. By means of the lower limit, the speed range of the drive. The standard is 1:10, but if you need a wider range, you should give preference to vector converters Bosch VFC5610.

By the number of control inputs The digital inputs are used for various control commands, as well as feedback signals. With the help of digital inputs, high-frequency signals are input from digital speed and position sensors. The larger their number, the higher the cost, since the Bosch VFC3610 converter allows you to create a more complex system.

By the number of output signals To output different signals, discrete outputs are used, their analogs are also used to construct a complex feedback system.

The selection criteria correspond to the previous paragraph.

On the control bus To adjust the operation of the model selected, the converter uses special equipment. It should have a similar bus, the number of inputs and outputs, as in the converter.

The capacity of the equipment should be 10-15% higher than that of the engine. The current level should be greater than the rated current and slightly exceed this figure, taking into account possible overloads.
