Q: Frequency converter, fault, contact action: Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?: System overviewA. load - constant power propertyWhen the gearbox changes, the torque varies inversely with the speed. Excluding the loss of the gearbox, it has the characteristic of constant power in the full power range.1) the speed grade speed control box has 8 gears speed: 75, 120, 200, 300, 800, 1200, 15002000r/min.2) the main rated parameters of motor, rated capacity: 3.7KW, rated speed: 1440r/min, load characteristics: constant power3) the control mode is controlled by 8 positions of the 8 handles, so that the four clutches can be divided and joined, and the 8 combinations of gears can be obtained, so as to obtain the speed of the two gears.The overload capacity of B. at low speed is strong, and the rated torque will be much larger than the maximum working torque of the load when the drive system is lowered at low speed, and it has a strong overload capacity

Q: Schneider 303 4KW frequency converter F 013 trouble shooting method: You see when the alarm is started, or stable operation alarm amount, different times, different analysis

Q: First of all, I would like to achieve the frequency converter with motor static linear acceleration, high-speed linear deceleration stop processFirst question: I say kind of situation, three paragraph speed start, 0.1hz---> high 30hz-->0.1hzSecond problem: manual speed instruction 1, speed 2, speed 3 instruction instruction I want to use PLC to control three speed motor with three reverse contact dry. I understand speed instruction 1 is switched on (2, 3 connected) transmission section set the frequency with the frequency segment set 0HZ123 AssociationThird questions: manual section, speed command, main frequency and STEP1-STEP7 stage setting frequency, I use PLC analog to the frequency main frequency setting, plus and deceleration, STEP1-7 are set 0, can achieve what I wantInitial contact frequency converter, home pointing: Using PLC to analog converter control input frequency up to speed off from the requirements of the inverter frequency source set P-00 speed by 00 digital operation panel to analog frequency PLC given 0102 given frequency parameters can choose the set of 01 or 02 and the period of quick closing even P-17P-19 parameters affect analog control

Q: What is the working principle of elevator frequency converter?: The basic principle of VVVF elevatorAccording to the theory of motor, the speed formula of AC motor is:N=60f (1-s) /pUpper type: F is the stator frequency, and P is the pole count;S is slip; n is speed.

Q: What does the base frequency 60Hz represent in the inverter?: If the motor chooses a special AC frequency conversion motor, the motor is always marked with constant torque and constant power speed range. For example, Mark 5 ~ 100HZ for constant torque, 100 to 150HZ for constant power, the basic frequency should be set to 100HZ. The fundamental frequency parameter directly reflects the relationship between the output voltage and the output frequency of the inverter. If it is not set properly, it is easy to cause the overcurrent or overload of the motor. For example, an AC motor rated voltage 380V, rated frequency is 60HZ, if the frequency is lower than that of converter 60HZ V/F, a high proportion of the output voltage as high frequency, high output current, at startup, easy to cause the flow. If the frequency converter is set higher than 60HZ, low V/F ratio, the output voltage of the same frequency is low, the output current is low, at startup, can easily lead to the start and overload.

Q: What does Ro1c mean on a converter?: Relay output converter dry contact signal, RO1C is the common end and RO1A is closed, RO1B is normally open, this set of contacts is prepared to run the factory setting output signal, power on self-test is completed can run the relay output signal. It can be modified to the output point of the signal such as fault and operation in the twenty-fourth set of parameters.

Q: How to maintain the frequency converter will not damage, or regular maintenance?: The correct use method and reasonable maintenance can extend the service life of the inverter to a certain extent. The common maintenance methods of the inverter are cleaning the air filter, cooling the air duct and the interior dust. Check whether the screws, bolts and plug are loose, the input and output reactor ground and interphase resistance is short circuit, the normal should be more than tens of megabytes of europe. The conductor and insulator are corrosion phenomenon, if in time to wipe clean with alcohol.

Q: There is much dust and moisture in my workshop. Many brands are not durable.: Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: There are only three reasons for the POFF fault: (1) the DC bus voltage detected by the machine is seriously low. (2) lack of phase signal. (3) the voltage level parameter of 220V machine is wrong. [method] use the shift key on the keyboard or the mask to switch the display content to the display bus voltage status.
