Q: How does the frequency converter change the voltage and change the speed of the motor?: N = 60f/PN is the turn speed, F is the frequency, and P is the magnetic pole logarithm of the engineBy the formula: frequency and speed is proportional to, so the inverter can change the speed of the motor

Q: How can I learn the converter well?: Frequency converter training teacher suggested: Theory + practice combinedTheory: understand the frequency converter each parameter meaning, the frequency changer principle, the control way, the instruction manual, the approximate operation, knows how the matterPractice: combined with some special requirements of practice to do the debugging, this needs the accumulation of experience

Q: What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: General environment temperature: inverter is an electronic device, containing electronic components, electrolytic capacitors, etc., so the temperature has a greater impact on its life. The environment of general inverter operating temperature of ~+50 DEG C - General requirements, if it can reduce the operation temperature of inverter, prolongs the service life of the transducer, stable performance. So heat dissipation is very important.

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?: Should be able to, in the design of the inverter in consideration of the corresponding motor power matching. Choose a large capacity, a little waste Oh! Our company choose frequency converter is one-to-one correspondence, did not choose the large capacity.

Q: What is the frequency converter through function?: Frequency converter is an ideal motor stepless speed regulating device. It is mainly used in three-phase and two-phase asynchronous motors. It has the advantages of small start-up current, smooth operation and complete protection facilities. The utility model is suitable for stepless speed regulation of various equipment.

Q: How can I control the frequency converter with a computer?: The commonly used PLC and DCS control system in industrial area are applicable to the conditions of inverter interface control module, can realize the closed-loop converter convenient automatic control in the control system, widely used in large and medium. The control device for some smallexperimental device and embedded processor in inverter control, generally also need to deal with the keyboard input, display, data acquisition and other work such as process control, this control is more suitable for single-chip control system as the core, and uses PLC and operation panel, it can achieve the function but the cost is too high. Should not be used.

Q: What are the benefits of installing economizer in industrial enterprises?: According to the frequency above 3 disadvantages, we developed and produced for Saver series under different conditions, based on frequency conversion technology, according to the field of electricity, increase control cabinet, electric / power conversion system, load detection and control system, input and output filter, DC reactor device etc.. The economizer has 4 advantages over the inverter:

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: 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.

Q: I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: The general frequency converter adopting vector control mode can not only match the DC motor in the speed regulation range, but also can control the torque generated by the asynchronous motor. The vector control method is based on the parameter of controlled asynchronous motor accurately, some general inverter needs accurate input parameters of asynchronous motor when in use, some general inverter needs to use the speed sensor and the encoder. In view of the motor parameters may change, will affect the performance of inverter for motor, the model of vector control of induction motor parameter automatic detection, automatic identification, adaptive function has the general inverter, can automatically to motor parameter identification before with the function of the general inverter for normal operation in the asynchronous motor, and adjust the control related parameters in the algorithm according to the identification results, thus effectively to ordinary asynchronous motor vector control.
