Siemens inverter power no display

The main models of Siemens inverter in the Chinese market are MM420 and MM440.6SE70 series.

With its stable performance, rich combination of functions, and good torque characteristics, it occupies an important position in the inverter market. And with its strong brand effect, it broke the monopoly position of Japanese brand inverters in the Chinese market. According to the statistics of relevant professional market research institutions, Siemens high- and low-voltage inverters have occupied most of the industrial control market in the Chinese market. rate.

The Siemens frequency converter should enter the Chinese market earlier, so some old products such as the MICROMASTER, MIDIMASTER still have a large number of users in use, we first do an analysis of the common faults of these two series of products. For the MICROMASTER series inverter, our most common fault is the power-on display. The switching power supply of this series of inverters uses a UC2842 chip as the waveform generator. The damage of this chip will cause the switching power supply to fail to work, and thus it cannot display normally. The abnormal operating power of this chip also makes the switching power supply unable to work normally. For the MIDIMASTER series inverter, our common faults are mainly the damage of the drive circuit and the damage of the IGBT module. The MIDIMASTER drive circuit is driven by a pair of tubes to drive the IGBT module, which is also the most easily damaged component. , The damage is often caused by the damage of the IGBT module, resulting in high-voltage and large currents rushing into the drive circuit, resulting in damage to the components of the drive circuit.

Siemens, in the field of automation should be a well-known brand, PLC, man-machine interface, inverter, servo products, automation instruments, etc., almost all areas of automation control, in all industries have also won a good reputation.

The use of Siemens inverters in the Chinese market was first in the steel industry. However, at the time, the motor speed was still dominated by DC speed control. The application of inverters was still a new market, but with the continuous development of electronic components and control theory The continuous maturation, frequency conversion speed control has gradually replaced the DC speed control, become the mainstream of the drive products, Siemens inverter due to its strong brand effect in this huge Chinese market has achieved super-scale development, Siemens in the Chinese inverter market The successful development should be said to be the perfect combination of Siemens brand and technology. In the Chinese market, we can meet the early Siemens inverter mainly SIMOVERTA current source, and the SIMOVERTP voltage source, these inverters are also mainly due to the introduction of equipment into the Chinese market, there is still a small amount of use , And then in the Chinese market a large number of sales mainly MICROMASTER and MIDIMASTER, as well as the most successful series of SIMENS inverter SIMOVERTMASTERDRIVE, which is what we often say 6SE70 series.

Non-contact measurement methods are mainly divided into two categories.
One is a passive method, that is, does not require a specific light source, depends entirely on the natural light conditions of the object to scan, often using binocular technology, but the accuracy is low, only objects with geometric features can be scanned, can not meet the requirements of many fields .
The other is the active method, which is to project a specific light to the object, which represents the technical laser line scan, the accuracy is relatively high, but because only one light can be projected at a time, the scanning speed is slow. In addition, because lasers can cause harm to living organisms and more precious objects, they cannot be used in certain areas.
The emerging technology is structured light scanning. Structured light is also an active method. By projecting or rastering multiple light rays at the same time, one surface of the object can be taken. Only a few surfaces are needed to complete the scan. Yes
 
3D Scanner
Scanning speed is fast and programmable.
There is also a low frequency pulse wave (low frequency sound wave) type principle, which is mainly used for level measurement. The low-frequency pulses are transmitted based on the two-dimensional array beamformer and the 3D level scanner receives echoes from the silo, bin, or other chamber material. The digital signal processor of the device samples and analyzes the received signal. By estimating the time and direction of arrival of the echo, the processor forms a three-dimensional map of the surface of the material. This image is processed by a proprietary calculation method. And generate 3D images, which can be displayed on the remote screen. The level gauge can accurately calculate the volume and quality of materials according to this, enough to make the process level monitoring and inventory control reach a new height. Accurate material inspection of level gauges can improve operational efficiency and management capabilities, reduce the high cost of unexpected situations, and accelerate revenue returns.
