The specific method is as follows: Use a multimeter to detect the characteristics of the rectifier bridge in the rectifier section. Use the ohm range X100 of the multimeter. Connect the red test lead to the "P" terminal of the frequency converter, and use the black test lead to connect to the input "R", "S", "T" respectively. The meter needle should swing at 2/3. If it exceeds 2/3 or is lower than 1/2, it is regarded as abnormal. Exchange the black and red test leads and measure again. The meter needle should not swing. If it swings, it is abnormal. Use the ohm range X100 of the multimeter. Connect the red test lead to the "N" terminal of the frequency converter, and use the black test lead to connect to the input "R", "S", "T" respectively. The meter needle should swing at 2/3. If it exceeds 2/3 or is lower than 1/2, it is regarded as abnormal. Exchange the black and red test leads and measure again. The meter needle should not swing. Otherwise, it is abnormal. Check the inverter section in the same way, replace "R", "S", "T" with "U", "V", "W", because there is also a rectifier bridge characteristic between the source and drain of the IG of the inverter in the off state. Insulation test. Conduct high-voltage insulation detection on the input and output terminals and the ground (shell). Connect the black test lead of the 500v megger to the grounding mark of the frequency converter. Connect the red end to "R", "S", "T", "U", "V", "W" respectively. Shake the megger at a uniform speed. The measured insulation resistance should be above 5M. Capacitor detection. The main circuit is mainly composed of three-phase or single-phase rectifier bridges, smoothing capacitors, filter capacitors, IPM inverter bridges, current-limiting resistors, contactors and other components. Among them, the smoothing aluminum electrolytic capacitor has the greatest impact on the service life of the frequency converter. Its service life is mainly determined by the DC voltage applied across it and the internal temperature. When designing the main circuit, the model of the capacitor has been selected according to the power supply voltage, so the internal temperature plays a decisive role in the service life of the electrolytic capacitor [Youlun Thesis].
How to manually set the frequency of the Siemens frequency converter?
1. Parameter 700 is the starting signal. 1 means starting by the panel buttons, 2 means starting by an external signal;
2. Parameter 1000 is the frequency setting value. 1 means changing the frequency by the up and down symbol buttons on the panel, 2 means changing by an external analog signal.
3. Set the starting signal by yourself, then change parameter 1000 to 1 to set the frequency on the panel, and then set parameter 1031 to 1 to automatically save the changed frequency value.
A frequency converter is a power control device that applies frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by the on and off of the internal IG, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation. In addition, the frequency converter also has many protection functions, such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of the industrial automation level, the frequency converter has also been widely used.
Siemens frequency converters were first used in the market in the steel industry. However, at that time, DC speed regulation was still the main method for motor speed regulation, and the application of frequency converters was still an emerging market. But with the continuous development of electronic components and the continuous maturity of control theory, variable frequency speed regulation has gradually replaced DC speed regulation and become the mainstream of drive products. Siemens frequency converters have achieved super-scale development in this huge market due to their strong brand effect. The * development of Siemens in the frequency converter market should be said to be the * combination of the Siemens brand and technology. The early Siemens frequency converters we can encounter in the market mainly include the current source SIMOVERT A and the voltage source SIMOVERT P.
