Q: Schneider 303 4KW frequency converter F 013 trouble shooting method
If the converter is overloaded, it is recommended to check the set acceleration time and whether the load is blocked or not.
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: Ask, what is the ratio of frequency converter?
Connect the air switch, the power supply, check the wiring is correct, close the air switch, turn on the frequency converter, and the digital tube shows 0.Turn off the power, the power indicator light is extinguished, then connect the motor, on-off switch, tone potentiometer, trimmer potentiometer, inching button, frequency meter (0 ~ 10V voltage meter), three sets of inverter and motor proportion of joint operation, the inverter and the motor grounding terminal reliable grounding, and carefully check.
Q: Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?
Asynchronous motor is the torque between the current flowing through the motor flux and rotor as a result of the interaction, at rated frequency, but only if the voltage will reduce the frequency, then the magnetic flux on a large magnetic circuit saturation, the motor will be seriously burned. Therefore, the frequency and voltage should be changed proportionally, that is to say, to change the frequency, to control the output voltage of the converter at the same time, to keep the flux of the motor to be certain, and to avoid the occurrence of the weakening of the magnetic flux and the saturation of the magnetic flux. This control mode is mostly used in fans, pumps and energy saving inverters. The frequency changer changes the voltage, must change the frequency
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?
Motor 90KW, frequency converter, 90KW can be applied, but the frequency can not exceed the rated value of the motor. There are some occasions to live and use the frequency converter to speed up the motor, so it should be chosen a little larger, otherwise the inverter will be more loaded.
Q: What are the benefits of installing economizer in industrial enterprises?
Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.
Q: What role does input and output reactor play?
The working principle of frequency converter:Normally, a device that changes the alternating current of voltage and frequency to a voltage or frequency variable alternating current is called a frequency converter". The device must first convert three-phase or single-phase AC to direct current (DC). Then the direct current (DC) is converted to three-phase or single-phase alternating current (AC). The frequency converter changes the output frequency and voltage at the same time, that is to change the N0 on the motor running curve, so that the motor running curve is parallel and downward. Therefore, the frequency converter can make the motor start with a smaller starting current to obtain a larger starting torque, that is, the frequency converter can start heavy load, and the inverter has the basic functions of voltage regulation, frequency modulation, voltage regulation, speed regulation and other basic functions
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: If you don't plug in the PG card, do you use PLC's PID control?Plug in the PG card and the PLC PID control, which is reliable and precise?
Mainly depends on what you want closed loopIf it is speed closed-loop, with PLC, you can not use PG card, direct PLC acquisition speed as a negative feedback signalIf it is a closed loop of ordinary process variables, such as pressure, temperature, etc.Neither PLC nor PG cards are requiredThe PG card is mainly used in the speed closed loop of the converter to collect signals
Q: Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?
The electronic governor for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the output power supply for power has not changed, so the speed is not a kind of energy-saving control methods, such as the electric fan like for home.
