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: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: 1, there are no special specifications, but each oneThe manual must have all the precautions required for good shielding.When the output of high frequency voltage pulse, the higher the frequency, the greater the external radiation interference. UseThe line is mostly blockedExternal interference.2, if there is no other equipment around (usually 5 meters as the boundary), then the shielded line can not be used, because there is no external interference.

Q: What is the function of a frequency converter on an electric motor?: 1, when starting, can reduce the starting current (relative to no inverter directly start the motor),2, long-term operation is more energy saving than frequency converter,3 、 stepless speed regulation can be carried out, vector control, V/F control, etc.4, the use of frequency converter communication function, the upper functions of real-time monitoring motor operation (such as current, speed, etc.)5, other.

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: What are the precautions for frequency converter wiring installation?: 1, between the power supply and inverter, access to low-voltage circuit breaker and contactor, protection of frequency converter and easy installation and maintenance;2, frequency converter and motor are generally not allowed to access contactor;3, frequency converter generally does not need to meet the thermal relay;4, the output side of the inverter is not allowed to connect capacitors and capacitive single-phase motors.5, the surrounding pay attention to ventilation, dust-proof6, the power input line has sufficient area, the screws tighten as far as possible, but do not slip, you can refer to the specifications torque.7, connect the motor cable as short as possible, there are computer occasions, as far as possible shielded cable8, the control signal line should not parallel to the power line. If parallel must be used, the shielding line and one end of the earth will be used.9, use 485 or 232 communication to wear a magnetic ring, and use twisted pair.

Q: How to deal with the fault Yaskawa inverter GF: Inverter display "GF" fault information for ground fault (i.e. the output current exceeds the rated current of the inverter 50%), a power module is reported for G5 damage, may also be a driving circuit, running the report "GF" (the external load is a good case), G5 is PC929 damage. With current detection circuit,

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: 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: I would like to ask, the inverter in use in the grid is very high?: In the process of using frequency converter, the demand for voltage fluctuation of power grid is not high, generally single-phase is allowed to + 20% fluctuations, three-phase is allowed to + 15% fluctuations.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: What do you mean by the capacity of the inverter and the capacity of the motor?: Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone
