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.
