Q: What are the modes of operation of a frequency converter?: If the inverter is still protected within a specified period of time, the running curve of the starting P should be changed, from the straight line to the S, U, or reverse, S, and U lines. When the motor load is large, a longer start stop time should be adopted, and the operation curve type should be set according to its load characteristics. 41 If the inverter is still running failure, try to increase the maximum current protection value, but can not cancel the protection, there should be at least 10% to 20% of the protection margin. 51, if the frequency converter operation failure or replacement, should be replaced by a larger power converter. 61 If the inverter drives the motor in the start-up process can not reach to the preset speed, there may be two cases:

Q: Application of ABB frequency converter: Why is the voltage of the inverter proportional to the current?Asynchronous motor is the torque between the current flowing through the motor flux and rotor as a result of the interaction, at rated frequency, but only if the voltage will reduce the frequency, then the magnetic flux on a large magnetic circuit saturation, the motor will be seriously burned. Therefore, the frequency and voltage should be changed proportionally, that is to say, to change the frequency, to control the output voltage of the converter at the same time, to keep the flux of the motor to be certain, and to avoid the occurrence of the weakening of the magnetic flux and the saturation of the magnetic flux. This control mode is mostly used in fans, pumps and energy saving inverters.

Q: Why does the frequency converter cause interference?: Isolation of interference: the so-called interference isolation is the separation of the source of interference from the susceptible part from the circuit so that they do not generate electrical contact. Usually in the power supply and controller and transmitter amplifier circuit, in the power line using isolation transformer, so as to avoid conduction interference, power isolation transformer can use noise isolation transformer.

Q: At the base block Yaskawa inverter is what reason?: This is the base block command, when the external input block command signal, the frequency converter will appear this code, the emergence of this code, the motor will rotate freely, does not affect the use.

Q: I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors): Yes, of course. The simple output is the AC contactor control. But if the two units move at the same time, they can only move synchronously, that is, the speed must be the same. Or you can see if there are two output inverters.

Q: What are the precautions for frequency converter wiring installation?: Pay attention to ventilation and dust preventionThe power input line has a sufficient area, the screws tighten as far as possible, but do not slip, you can refer to the specifications torque.Connect the cable of the motor as short as possible, use the shielded cable as far as possible in the computer

Q: PT100 temperature patrol instrument, when the converter is not open, the measurement is normal. Once opened, it shows completely disorder, and sometimes there are puzzling characters. How can I solve this problem? Please enlighten master!: If only the temperature measurement fluctuations, as the temperature is slow change, the filter is more effective way, the filter can use a passive RC low-pass filter, and then connected to the patrol instrument on the terminal can.

Q: What is the frequency converter through function?: Some inverter has this function, such as the ACS800 series has lost power across functions, can be in a temporary loss of power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in the state power grid voltage recovery after the inverter can be immediately put into normal electric state.The undervoltage controller needs to be activated (parameter 20.06).

Q: What are the possible causes of frequency hopping overload?: Because the overload is judged only by the current, it will happen at the start, stop, acceleration and deceleration, and constant speed operation. Moreover, the current and the asynchronous motor difference are inseparable, so the following conditions can be used for analysis and reference:

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?: You can try using the following methods:Solution of interference caused by circuit coupling:The PLC and monitoring equipment are powered by isolated transformers.
