Q: It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): Has the frequency converter been used for a long time? The inverter power placed on the two day, and then open, put the line inside the head plug again, and then boot general can solve the problem, new don't try

Q: What is the main function of the frequency converter on the machine tools?: Where is the difference between soft starter and converter?

Q: What is the function of a frequency converter on an electric motor?: Frequency converter integrates high voltage, high power transistor technology and electronic control technology, and has been widely used. The role of frequency converter is to change the frequency and amplitude of AC motor power supply, thus changing the period of its moving magnetic field, to achieve the purpose of smooth control of motor speed. The inverter speed control, makes the complex simple, most of the original work can only be done by a DC motor instead of frequency converter + AC squirrel cage induction motor, reduce the volume, reduce the maintenance rate, to a new stage of development of the transmission technology

Q: What does Ro1c mean on a converter?: RO1C is the common terminal and the RO1A is normally closed, and the RO1B is normally open. The set of contacts is the output signal that is ready to run. That is, the self-test of the converter is completed and the output signal of the relay can be operated.

Q: Why does the frequency change when the frequency converter regulates the frequency?: Main flux of motorM = U/ (4.44*f*N)In the upper model, the U is the stator voltage, that is, the output voltage of the inverter, f is the frequency, and N is the stator winding turn number.N is a constant.Obviously, when the frequency changes, if the voltage is constant, then the flux will change.The iron core of the motor is nonlinear, and when the flux changes, both too large (saturated) or too small (weak magnetic) is detrimental to the motor.Therefore, when changing the frequency, the voltage is changed, and the constant value of U/f is kept, so that the magnetic flux can be kept unchanged.

Q: What are the parameters of the frequency converter? Thank you: Inverter function parameters are many, generally have ten, or even hundreds of parameters for users to choose. In practical applications, it is not necessary to set and debug each parameter, most of which can only be used as factory settings. But some parameters have great relationship with the actual use, and some are related to each other, so they should be set and debugged according to the actual situation.Because of the type of converter function are different, but the same function parameter name is not consistent, but the type of converter is almost always some basic parameters, can be done completely by analogy. The following parameters are basically used:

Q: What is the frequency converter through function?: The default power loss time is 5S.Using DSU's high-power inverters, you need to set the time delay in DSU software to activate this function.The power down function is unique across some converter functions. In the power plant, semiconductor, petrochemical and other industries has been widely used to solve the power problem recurring and electricity, the massive economic losses caused momentary loss of power equipment downtime caused by continuous production. To protect the user to the greatest extent.

Q: There is much dust and moisture in my workshop. Many brands are not durable.: The quality is very good.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.

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: Solution of interference caused by inductive coupling:The control circuit using shielding line, when connected to the control line and the inverter, the shielding layer can not only be grounded, one end connected to the transducer signal terminal can pay attention to public, regardless of whether the public or end shield grounding, only in the end, and can not be connected at both ends.

Q: Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?: Is the original power inverter direct input three-phase asynchronous motor inverter in inverter internal access first, through PWM electronic converter technology will AC rectifier, inverter, a controllable frequency alternating current at the input to the motor, the motor operation can be controlled by V/F, output torque control and vector control control frequency, change the loop current, realize energy-saving operation, especially the energy saving effect is obvious in the motor at light load is a kind of energy-saving products, has been widely spread and applied.
