TechnicalAdvantage

Control mode

(1) VF control: Multipoint VF curve. This apply to the situation that one frequencyinverter drives multiple motors, such as fan, water pump, engraving machine,injection molding machine etc.

(2) Open-loop vector control: Steady speed with highprecision, wide range of speed governing, as the speed ratio is 1:150 and frequencyis 0.5Hz, we could output 150% rated torque. Good dynamic performance.

Q: The parameters of the inverter is 4, 6 motor can be used: The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.

Q: Three-phase asynchronous AC motor speed control method: Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch to full speed operation, to avoid shutdown; Thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders.

Q: How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?: Although the waste, but can be used, we use the frequency band with two-speed motor when the output is connected to the fast three terminals, you can refer to the next

Q: What is the motor series parameter setting of the inverter? If it is with the spindle,: The number of motor poles can be estimated by the parameters: 1000Hz corresponds to 60000rpm, According to "Speed in rpm = 60 * Frequency in Hz / (Number of Poles / 2)", Number of poles = 60 * Frequency indicated by Hz * 2 / Speed in rpm = 60 * 1000 * 2/60000 = 2 poles. The same is true with 333Hz and 20000rpm projections. The number of motor poles for the frequency converter should be entered with the number of poles of the motor that are directly connected to the frequency converter.

Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?: 1,2P refers to the number of motor poles, so it is certainly even 2, if the inverter is set to determine the number of motor poles, please write 2P value, if 2P = 4, please write 4 3, look at the nameplate on the motor rated speed for how much, you can confirm the number of motor poles. (N = 60f / p) P: pole pairs

Q: How to choose the inverter: and you need to know how The use of frequency converter, as well as voltage 380, are fixed, and the frequency can be changed

Q: What is the principle and implementation of the inverter?: AC-DC is relatively simple We know that the diode has a one-way conductivity You can use this feature of the diode into a bridge So that the other end is always flowing into the other end is always out of the way it gets the voltage sinusoidal change of the DC If the need for smooth DC also need to be rectified Simple method is to connect a capacitor

Q: Fuji inverter motor set the number of poles will not have any effect?: The number of poles is not the same as the speed is not the same mistake machine can not work or motor coil burned

Q: 400w 6-pole motor should be equipped with much of the inverter?: 400w 6-pole motor with frequency converter, as long as 1kw inverter can be a.

Q: Quartet of the TA, TC terminals have positive and negative?: The TC terminal has no positive and negative poles, which are passive programmable relays
