Q:I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors)
I suggest you use SIEMENS's 6SE70 model converter (I used this to do a lot of track debugging, it's really easy to use and not easy to go wrong)Communication with the PLC, as long as the Profeibus link on the good, communication and control characters are very good setRemark: a multi motor controlled by a transducer must start and stop at the same time, and the control speed is the same
Q:What is frequency conversion? What is the function of frequency converter?
Theoretically, the inverter can be used in all mechanical equipment with electric motor, the motor starts, 5-6 times higher than the rated current, will not only affect the motor service life and consume more power. In the design of the system in the motor selection will leave some margin, the speed of the motor is fixed the same, but in actual use, sometimes running at low or high speed, so the frequency transformation is very necessary. Transducer can realize soft starting and compensating power factor of motor
Q:At the base block Yaskawa inverter is what reason?
For example: when you put the inverter to stop, there will be a signal to the inverter, then the converter will base the blockade, cut off the output, the motor will no longer work; when you need a converter work, there will be a signal to the inverter, inverter will cancel the locks on the base, and the normal work,This function is only equivalent to one protection.
Q:That is, some parameters of the inverter, such as torque, current, frequency, etc., are displayed on the Kingview software interface, but not through the PLC. The idea that the MODBUS protocol between SIEMENS and 200PLC has never been successful before, so that's the idea of the ABB. If it can be achieved,Is it necessary to write the script program on the Kingview, and what problems should I pay attention to when using the MODBUS protocol in Kingview software?The problem is a little bit more, I hope the experts teach me this rookie! Thank you
ABB converter supports MODBUS protocol, can be directly connected to the ModbusRTU in your choice of Kingview, device configuration, set up converter address directly in Kingview read the corresponding parameters can be
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:Does the number of inverter settings differ from the number of motor poles, and does it affect the use?
Frequency converter has a number of requirements, if the motor is not set by the number of motor parameters, I think there will be the following problems, but may occur, I have not been verified:
Q:High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?
According to the classification of link Transformation: (1) the AC-DC-AC converter is the first AC into DC rectifier through, and then transformed into the frequency DC voltage adjustable AC inverter, also known as indirect, is currently widely used general-purpose inverter. (2) can be divided into cycloconverter, is directly converted into AC voltage adjustable frequency AC, also known as direct inverter DC power supply according to the classification of properties: (1) the voltage type inverter voltage type inverter is characteristic of DC link energy storage device using a large capacitor load reactive power will be it is to buffer the DC voltage, DC power supply is relatively stable, smaller internal resistance and the equivalent voltage source, so that the voltage type inverter, are often used for load voltage changes in the larger situation. (2) current inverter current type inverter is characterized by large DC link inductance as a storage buffer of reactive power, which changes the current control, the voltage is close to sine wave, because the DC resistance is large, so that the current source converter (current). The characteristics of current source inverter (advantages) can restrain the load current is frequent and rapid changes.
Q:Why does the frequency change when the frequency converter regulates the frequency?
Main flux of motorM = U/ (4.44*f*N)In the upper model, the U is the stator voltage, that is, the output voltage of the inverter, f is the frequency, and N is the stator winding turn number.N is a constant.Obviously, when the frequency changes, if the voltage is constant, then the flux will change.The iron core of the motor is nonlinear, and when the flux changes, both too large (saturated) or too small (weak magnetic) is detrimental to the motor.Therefore, when changing the frequency, the voltage is changed, and the constant value of U/f is kept, so that the magnetic flux can be kept unchanged.
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?
You refer to the type and parameters of the frequency changer to select.
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.
