After setting the frequency source to 2, just like the command source mentioned in the previous section, first understand the communication protocol supported by the frequency converter, set the communication parameters, connect the communication cables, and after establishing the communication connection, the frequency of the frequency converter can be given by sending the corresponding value to the register address corresponding to the frequency source through communication on the upper computer, such as touch screen, PLC, or DCS. Some values are given in percentage Some are given frequency values, please refer to the frequency converter manual for details.

It is worth mentioning that when the i550 motec, m550 motor, and g500 gearbox are combined, due to their perfectly coordinated interface, they can flexibly achieve excellent energy-saving driving solutions, ensuring optimal performance and energy efficiency during operation.

Energy saving effect: The new Kerui frequency converter is used in the main fan to control wind speed, effectively changing the output of air volume and pressure, achieving the goal of energy conservation. The use of a fan as a frequency converter load device directly affects the speed of the fan. From the perspective of fluid science, the relationship between rotational speed and flow rate is proportional, the pressure of the fluid is proportional to the square of rotational speed, and the shaft power P is proportional to the cubic power of rotational speed. From the practical effect, it can be seen that the speed of the fan has been reduced by half,

 and the natural energy consumption has also been reduced by one eighth, indicating that the gearbox has achieved energy-saving of the main ventilation fan. Moreover, most coal mines use a fan to drive two motors, so based on this feature, one frequency converter can simultaneously control the normal operation of both motors. Regardless of the driving method used to control the power of the frequency converter, the total power cannot be smaller than the sum of the two motors.

By using the i550 MOTEC frequency converter, Lenz can achieve transparency in the process from the transmission shaft to the cloud for our customers and support their digital transformation.

The IO Link master station function equipped with the i-series MOTEC frequency converter provides real-time recognition and diagnostic data from sensors, allowing for easy data exchange between IO Link sensors and actuators. By using Drive DataHub to connect to the cloud, it also saves additional hardware and installation costs, and performs well in status monitoring or predictive maintenance.

Today we will explain an important concept of frequency converters: frequency sources, and some brands may refer to them as given channels. In fact, what we are talking about is the same thing. Previously, as long as a running command was given to the frequency converter, it was already running. However, if the frequency was not given and the frequency was set to 0 at this time, even if the frequency converter was already running, the motor would not rotate due to the output frequency of the frequency converter being 0. Therefore, in general, both the command source and frequency source need to be given simultaneously. The command source is responsible for starting and the frequency source is responsible for controlling the speed, Only in this way can a frequency converter be used to control the motor for speed regulation.
