Q: A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?: A) PE inverter main circuit terminals (E, G) must be grounded, the motor can be grounded and the inverter with the common ground, but not with other equipment, must play ground pile, and the ground should take place far away from electrical equipment. At the same time, the cross-sectional area of the grounding wire of the converter shall be no less than 4mm2, and the length shall be within 20m.(b) in the ground wire of other electromechanical equipment, the protective earthing and the work earthing shall be separately provided with grounding electrodes, and finally shall be imported to the electrical position of the distribution cabinet. The shield of the control signal and the shielding of the main circuit wire shall also be separately provided with earth electrodes, and finally shall be incorporated into the electrical junction of the distribution cabinet.

Q: How does the frequency converter fit the brake unit and the brake resistor?!: When the motor drives the motor to stop, the load on the motor is kinetic, and the motor must be consumed to stop the motor

Q: The functions of frequency converter and UPS are similar, especially the power frequency UPS?: The obvious difference between the two:1, the former output amplitude and frequency adjustable, the latter output is a single fixed amplitude, frequency;2, the former does not use batteries, and the latter requires batteries.

Q: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Overvoltage prevention measures: due to over-voltage causes are different, so the countermeasures are not the same. For overvoltage in parking, if there is no special requirement for parking time or position, it can be solved by using extended frequency converter, deceleration time or free parking. The so-called free parking, that is, the frequency converter will switch off the main switch, so that the motor free sliding stop. If the parking time or parking position have certain requirements, then the DC brake (DC brake) function can be used

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: What are the differences between the two quadrant and the four quadrant of the inverter?: Simply put, the two quadrant ordinary inverter can only drag the motor forward or reverse. Work in one and three quadrants. The kinetic energy of the motor idle time can only be wasted. (of an electric motor)

Q: What does the RUN key on the inverter mean? How do you use it?: According to the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are many inverter protection functions, such as over-current, overvoltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: What are the possible causes of frequency hopping overload?: If the motor and inverter adapter, because the motor overload in inverter, this time is called the overload overload of the transducer, the current inverter rated current is compared; if the motor rated current is less than the rated current of inverter, the correct input motor nameplate and protection, the overload protection is often referred to as motor overload protection. Therefore, we must distinguish the specific circumstances of the current protection. Because of the overload point of the converter and the overcurrent point of the converter, the two protection alternates frequently.

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?: There are several kinds of closed loop, speed closed loop, temperature / pressure / flow closed loop.Since you're talking about PG cards, then obviously you have to control speed.Generally speaking, the control precision is related to the hardware, and the PLC can also output pulses.If you are small system, simple control, it is recommended that you use PG card + encoder to save the cost, you can inverter internal PID, and control accuracy is also ok.My feeling, as if the speed control precision is high, is PG card.

Q: I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: No PG vector control (motor with encoder), set the motor parameters self-learning, rated voltage, rated current, fundamental frequency (50, 33.3, 20 HZ motor should pay attention to what kind of), pole number, frequency speed, rated power, the maximum output frequency, etc., set the end after the rotation form self-learning (motor without load), or stop shape self-learning. Even the self-learning control model parameter to the external terminal control, analog voltage is changed to external control, can be CNC, PLC or PC to control its operation.
