Q:What is the difference between SIEMENS inverter and built-in filter?: SIEMENS built-in filter optional three. Class a EMC filter. B class EMC filter. LC/ sine filter.Power 110KW to 250KW converter, optional external or built-in level a filter,The power 7.5KW to 15Kw converter, in addition to additional B class EMC filter, can be equipped with a class EMC filter.The LC/ sinusoidal filter can effectively suppress the rise of voltage and capacitance charge / discharge current in the variable frequency drive. But there are many restrictions: only V/F is allowed. FCC control mode. To comply with the 15% drop capacity, the output frequency limit is 150HZ, and only allowed to operate at the 4KHZ pulse frequency. In operation and debugging, the LC sinusoidal filter must be connected to the motor.

Q:What are the parameters of the frequency converter? Thank you: Also called torque compensation, in order to compensate for the motor stator winding resistance caused by low-speed torque reduction, and the low frequency range f/V increased method. When the utility model is set as an automatic, the voltage in the acceleration can be automatically raised to compensate the starting torque, and the motor can be accelerated smoothly. If manual compensation is adopted, according to the load characteristics, especially the starting characteristics of the load, the better curve can be selected through the test. For variable torque load, such as improper selection, the output voltage is too high at low speed, while the phenomenon of waste of electricity, and even the emergence of motor load with a large current, while the speed does not go.

Q:What does "frequency" in household appliances mean?: The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;

Q:When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: If the load of the motor is increased, the slip S is increased, the electromotive force of the motor is decreased, and the electric current of the motor will become larger. That is to say, when the motor is running in the overclocking stage, the load of the motor is light, the current will become smaller, and the current will not be smaller if the load is negative. Didn't I make myself clear?

Q:How can I control the frequency converter with a computer?: The use of single-chip to control the inverter can choose the last two kinds of methods, the use of communication control, the utility model has the advantages of full control function, suitable for inverter through the level conversion circuit form of communication (RS484/RS232/CAN), you can communicate with the inverter hardware is simple, the number of connections between the two less convenient connection. The disadvantage is that we need to understand the communication protocol of frequency converter to control programming, and the software design is complicated. The inverter communication interface and communication protocol of different brands are different, there is no uniform standard, only for a converter for development, narrowing the selection range of the frequency converter varieties, the applicability is limited. As for the analog input control, can support almost all of the inverter is, although the function is relatively simple, but the main function can realize speed, can meet the use requirements of the majority of occasions, universal.

Q:The difference between soft starter and converter: The soft starter is just a thyristor pressure regulating device is simple to start the motor, the motor speed can not be normal, low price; inverter is the AC power supply voltage and frequency, can IGBT chopper can be used to start the motor, can also be normal speed, the price is relatively expensive

Q:What is the main harmonic produced by a transducer? How about the degree?: Indirect frequency conversion has three different structure forms: (1) using controllable rectifier to change voltage, frequency conversion with inverter, voltage regulation and frequency modulation are carried out in two aspects respectively, and the two should coordinate with each other in control circuit. (2) with uncontrolled rectifier rectifier chopper inverter transformer, inverter, filter the inverter rectifier, voltage with pulse width (3) with uncontrolled rectifier rectifier, PWM inverter and inverter, this inverter device fully controlled only by controlled shutdown (such as IGBT) can output waveform is very realistic sine wave.

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.: The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.

Q:What's the role of an electric car, the part of a traditional car?: Optimal energy utilization.The optimal utilization of energy is another basic requirement of electric vehicle, the control system can be as much as possible the use of energy, including the use of overheating and regenerative braking energy, make full use of limited energy. Ability feedback can implement this function. It includes two kinds of vehicle braking capability feedback and vehicle coasting ability feedback. In our state, the drive motor according to the operation of the generator, the vehicle kinetic energy into electricity, can play 3 roles: auxiliary braking; energy recovery to the power battery, thereby prolonging the vehicle mileage; in vehicle heating demand, can directly use this energy heating.

Q:How do you understand the ramp up (descent) time of the inverter? Thank you!: The reverse is the drop time, or the 0 speed. Water pumps and fan motors are basically not required to change. If it is an emergency stop, it is usually 3 seconds (depending on the frequency converter and process requirements).
