Q:What is the TTK converter produced?
Characteristic:Compact structure design, flexible installation, advanced control algorithm: space voltage vector control technology, power failure restart, automatic voltage adjustment, dead time compensation, energy saving operation,The main and auxiliary setting, built-in PID, simple PLC, oscillating frequency and zero frequency difference, length control, precision control requirements; design and test in accordance with international standards, to ensure the reliability of the product; choose rich accessories.
Q:What's the use of switching frequency of converter?
The chopper device also has switching life, the higher the switching frequency, the shorter the life of the inverter, and will reduce the inverter output current and power. The smaller the chopping frequency, the higher harmonic content and the more serious harmonic pollution.
Q:What is the difference between a frequency converter and a servo controller?
The inverter is actually an inverter. It is the first AC into DC. And then use the electronic element to switch DC power into AC inverter. In general. Large power SCR. And an adjustable frequency. The device can be adjusted in a certain range of frequency is used to control the motor speed. The speed can be adjusted. In a certain range. The inverter is widely used in AC motor speed.Frequency conversion motor and AC motor is not very different, but the high-frequency loss of materials used is small. Ordinary AC motors can also be frequency conversion speed regulation
Q:What is the working principle of elevator frequency converter?
Yaskawa 616G5 transducer current vector in the world as one of the inverter control, speed range to reach 1:1000, the control accuracy of 0.02%, with the starting torque at zero speed can reach 150% characteristics. In particular, Yaskawa unique all fields, automatic torque boost function can get comfort and good stability in the lift drag in.G5 can accept controllers such as multi speed frequency command PLC or analog voltage and current instruction; can adapt to all kinds of motor vector control and self-learning to obtain good characteristics; low speed starting smoothly excellent reliability and high cost of hardware.
Q:What is the difference between SIEMENS inverter and built-in filter?
There is no built-in filter converter in the price slightly lower, mainly used in the equipment efficiency (power factor) requirements are not high, anti-interference ability requirements are not strict place;The frequency difference with built-in filter is mainly to the requirements of different electrical parameters in specially designed, can improve equipment (power factor), has the good anti-interference ability, prevent the transient surge of inverter module impact, has a good protective effect.
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:How can I learn the converter well?
Frequency converter this thing, in fact, still very practical, so can go to customers to install and debug, is a shortcut to quickly learn the frequency converter. In the installation of debugging, you can take time to read several times the frequency converter manual, and if you can discuss with technical support, I believe you will soon enter the role.
Q:What does a frequency converter do?
What is the starting current and starting torque of the motor when the inverter is in operation?Using frequency converter operation, with the acceleration of the motor, accordingly improve the frequency and voltage, the starting current is limited to 150% rated current (according to the type of machine is 125%~200%). The starting current is 6~7 times of direct starting with the mains frequency power supply, so the mechanical and electrical impact will be produced. It can start smoothly with frequency converter (longer starting time). The starting current is 1.2~1.5 times the rated current, the starting torque is 70%~120%, the rated torque; for the inverter with automatic torque enhancement, the starting torque is above 100%, and the full load can start.
Q:What does "frequency" in household appliances mean?
The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;
Q:What are the differences between the two quadrant and the four quadrant of the inverter?
For a motor alone, the so-called four quadrant refers to its operating mechanical characteristics curve, on the mathematical axis of the four quadrants can run. The first quadrant is in the positive electric state, the second quadrant feedback braking state, the third quadrant reversing electric state, and the fourth quadrant reverse braking state. A frequency converter that makes the motor work in the four quadrant is called the four quadrant converter.
