Q:What is the difference between SIEMENS inverter and built-in filter?
SIEMENS built-in filter optional three. Class a EMC filter. B class EMC filter. LC/ sine filter.Power 110KW to 250KW converter, optional external or built-in level a filter,The power 7.5KW to 15Kw converter, in addition to additional B class EMC filter, can be equipped with a class EMC filter.The LC/ sinusoidal filter can effectively suppress the rise of voltage and capacitance charge / discharge current in the variable frequency drive. But there are many restrictions: only V/F is allowed. FCC control mode. To comply with the 15% drop capacity, the output frequency limit is 150HZ, and only allowed to operate at the 4KHZ pulse frequency. In operation and debugging, the LC sinusoidal filter must be connected to the motor.
Q:What are the contents of frequency converter maintenance?
Routine inspection itemsShould first check the temperature and humidity of the surrounding environment before power on, too high temperature will cause the inverter overheat alarm, will directly lead to serious damage, the inverter power devices short circuit; air is too humid will lead to internal direct short circuit inverter. In the inverter operation, should pay attention to its cooling system is normal, such as: whether the exhaust air flow smooth, fan whether abnormal sound. General protection level higher frequency converter, such as: IP20 or more frequency converter can be directly installed
Q:What does Ro1c mean on a converter?
Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.
Q:How can I control the frequency converter with a computer?
Variable frequency speed control has been applied in the industrial field as the main means of AC motor speed control is very extensive, it has a wide speed range, steady speed and high precision fast dynamic response for a wide range of technical performance and reliable operation, has gradually replaced the DC motor speed control system. There are three main control modes of inverter: 1. through inverter panel operation, that is through the operation panel to change the output frequency and other operating parameters; 2. in the frequency converter analog input 0 ~ 10V or 4 ~ 20mA signal, by changing the size of input analog control of inverter output frequency converter; 3. through communication port (for RS485 control). The first method is generally used for manual adjustment and parameter setting on the spot, and the latter two are mostly used for automatic adjustment and remote control.
Q:What are the basis of the frequency converter to choose?
1, brand, mainly for cost control2, performance, overload, function, reliability,3, load characteristics, constant torque, square torque or special load (determine the length of the cable of the load motor)4, environmental aspects: temperature, humidity. Altitude.These are the needs of attention when type selection.The last point is the most important, when choosing type, remember that the motor power can not be selected, must be selected in accordance with the motor current.
Q:What does "G" and "P" mean in the converter model?
G stands for constant torque, usually overloadedP stands for torque change, usually light load type
Q:Frequency converter OC alarm, what's the matter?
Description of the OC fault in the inverter manual, following several explanations: the load side short-circuit current greater than OC, run jump failure is two times; the output of the inverter module circuit; current transducer; overload; acceleration and deceleration time is too shortEtc.. Some models do not use OC to mark such faults. They are explained by load side short circuit, frequency converter overload, serious ground fault and so on. This is of course the alias of OC fault.
Q:What are the precautions for frequency converter wiring installation?
The control signal line should not be parallel to the power line. If parallel must be used, the shielding wire and one end of the earth must be used.To use 485 or 232 communication, wear a magnetic ring and use twisted pairs.
Q:Where is the frequency converter used?
In these industries, the use of small and medium power converters more, 220V/380V as its main model. Of course, the auxiliary facilities in these industries still have fans, pumps and inverters, but they don't use much.
Q:How to maintain the frequency converter will not damage, or regular maintenance?
1. cooling fan, inverter power module is the most serious heating device, the continuous heat generated by the work must be promptly discharged, the general fan life of about 10Kh-40Kh. According to the continuous operation of converter for 2-3 years, it is necessary to replace the fan2. filter capacitor, intermediate circuit filter capacitor: also called electrolytic capacitor, its main function is to smooth the DC voltage, absorb the low-frequency harmonic in dc.
