Q:What are the benefits of installing economizer in industrial enterprises?: 1, through the intelligent online detection control system, closed-loop control can be completed, to keep track of changes in the load, load, change the machine output parameters, meet the requirements of the production process for customers, when customers need full load motor, motor output is not enough.For example: a plant water pump, motor speed can be supplied to a 100 force, the force is now 80, with the inverter directly to the 20 removed, and if the production process of the customer needs to provide 100 force, there will be a lack of motivation, affect the customer's production process and product quality. Such as the installation of our power class Saver, will not be the case, it can change the parameters at any time according to the requirements of the load, to ensure the normal supply of power.

Q:What does "EPCU" mean in a frequency converter?: This code indicates external signal interference.It is possible that the power line and the signal line are coming together to check that the ground of the converter is ready.If not yet, that can only be considered in the inverter output end of the inverter output filter, or inverter output reactor to try.Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment.

Q:What is the over-current of the inverter?: When the load is not stable, recommend the use of DTC DTC control mode, because the speed is very fast, the actual torque and flux generated every 25 microseconds a set of precise value after comparator and output torque of the motor flux comparator, optimized pulse selector switch inverter decided to best position, such a system over current. In addition, the speed loop adaptive (AUTOTUNE) will automatically adjust the PID parameters, so that the inverter output motor current is stable.

Q:What does the base frequency 60Hz represent in the inverter?: How to set the frequency converter: inverter frequency parameter should be set to the rated frequency of the motor is set up, and not according to the load characteristic set, even if the selection is not suitable for motor load characteristics or parameters must also try to follow the motor, easy over-current or overload.

Q:What does a frequency converter do?: Mainly used to drive AC motors, AC motors to achieve stepless speed regulation.For example, for the fan, with frequency converter to adjust the speed of the motor speed, you can change the size of the air supply.There are many occasions that need speed regulation. Using frequency converter to speed up is simple and energy-saving.

Q:What is the difference between SIEMENS inverter and built-in filter?: The filter is used for electromagnetic interference protection. Not only for the protection of electrical equipment, but also for the use of environmental protection. Inverter application environment is very extensive. Industry, light industry, commerce, civil, etc.. So the level of electromagnetic protection is also different.By the way。 If you disconnect the converter. See a coil on a board. That's the built-in filter. If you don't have it, you don't have that coil.

Q:Where is the difference between soft starter and converter?: The utility model is mainly composed of a three-phase anti parallel thyristor connected in series between the power supply and the controlled motor, and an electronic control circuit thereof. Different methods are adopted to control the turn-on angle of the three-phase anti parallel thyristor, so that the input voltage of the controlled motor varies according to different requirements, and different functions can be realized. Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. 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. Soft starter and converter

Q:What is the TTK converter produced?: Mainly engaged in TTK brand inverter products R & D, manufacturing, SMT surface mount OEM processing, and agents of well-known brands at home and abroad, frequency converters and electronic components. The agent of many brands, manufacturers become the primary agent, after ten years of unremitting efforts, has formed the electronic components supply system, to meet the basic needs of all customers required inverter suction electronic components. Due to the rapid delivery, excellent reputation, has a large number of customers in East China. Now the Shanghai Volkswagen Schneider, L.D., and many domestic large enterprises supporting inverter and electronic components products supply, for many years by the number of units as the best supplier.

Q:How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: Motor 90KW, frequency converter, 90KW can be applied, but the frequency can not exceed the rated value of the motor. There are some occasions to live and use the frequency converter to speed up the motor, so it should be chosen a little larger, otherwise the inverter will be more loaded.

Q:Which brand of converter is better?: Supporting the use of Sinopec group, double coin group and other national key projects, the quality of product quality and good customer service service won the praise of users!
