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: What does the base frequency 60Hz represent in the inverter?: The schematic diagram of the basic frequency parameters of the converter is shown in figure.Below the fundamental frequency, the output voltage of the converter varies with the output frequency, and the V/F= constant is suitable for constant torque load characteristics.Above the fundamental frequency, the output voltage of the inverter maintains the same voltage rating of the power supply, which is suitable for constant power load characteristics.

Q: Check the fault information is the power supply voltage instability, but other inverters are running well, what is the matter? Will there be any other parameters are not set correctly, thank you!: Ha ha, we have a problem, always complicate the problem, always used to find problems from the frequency converter, but did not think the problem is in the most basic place......

Q: Ask, what is the ratio of frequency converter?: Rotating main potentiometer, respectively, to see the three frequency converter F1.00 parameters, keyboard digital display reference input, follow potentiometer changes, and the proportion of 1:1.5:2. Rotate three trimmer potentiometers respectively, and the reference input of the corresponding converter has little change.

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: 5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?: overloadOverload faults include frequency overload and motor overload. It may be caused by the acceleration time is too short, the network voltage is too low and the load is too heavy. Generally by extending the acceleration time, extending the braking time, check the power grid voltage. Overload, the selected motor and inverter can not drag the load, or it may be caused by poor mechanical lubrication. Such as the former, you must replace the high-power motor and inverter; if the latter is to overhaul the production machinery.

Q: What role does input and output reactor play?: The working principle of the reactor: the interference of capacitance and inductance in the circuit to the AC is called reactance. The inductor has the function of restraining the change of the current and the phase shift of the alternating current, and the winding static induction device with inductance is called a reactor. The dead are common reactor used in the power system with series reactor and shunt reactor. Series reactors are mainly used to restrict short circuit currents, and are connected in series with or parallel with capacitors in filters to limit the higher harmonics in the power grid. Reactors in the 220kV, 110kV, 35kV, and 10kV power grids are designed to absorb charging, capacitive, reactive, and reactive power in cable lines. The operating voltage can be adjusted by adjusting the number of shunt reactors.

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?: Reasonable wiring: 1. principle - control line as far as possible from the input and output lines.2. non parallel principle - the control line should be crossed as far as possible in the space and the input and output lines, preferably the verticalStraight crossing, not parallel.3. phase principle - two control lines are adjacent to each other.

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: Can a power converter be used in a motor with small power? Will it burn the motor?: Can a power converter be used in a motor with low power, depending on your load and what type of converter is it?.If it is only a common fan, water pump or light load operation, then basically no request, you can use, as long as the relevant parameters can be set.
