Q:Ask, what is the ratio of frequency converter?
Rotating main potentiometer, respectively, to see the three frequency converter F1.00 parameters, keyboard digital display reference input, follow potentiometer changes, and the proportion of 1:1.5:2. Rotate three trimmer potentiometers respectively, and the reference input of the corresponding converter has little change.
Q:What does the brake unit on the inverter mean?
The normal asynchronous motor in power loss, but also because of the inertia and load rotor rotate continuously for a period of time, at this time, due to the current of the rotor motor will still exist, such as the generator, sent to the power supply current. When a short circuit fault occurs, the motor also provides feedback current.
Q:Inverter switch display poff
When detecting the phase - lacking circuit, the phase - blank board is directly tested, and the PL signal on the drive board is normal. Normally, the PL is low, the phase is Fang Bo, and the power is high when the power is switched off. It is important to note that the PL signal output by the drive board or the phase blank panel is not sent to the CPU after the level switch has been passed on the main control board, and it should be noted that the fault is caused by the main board or the missing phase board during maintenance.
Q:What does 0L1 stand for?
The acceleration is generally overloaded during acceleration. Load inertia is too large, the inverter power is small, or the acceleration time is too short, and so on
Q:What is the traction frequency converter for electric cars?
Vector converter (motor controller) in the electric vehicle is the DC power source into AC output, drive three-phase motor, and then the electrical energy into mechanical energy to drive the car running. It is the core part of the whole electric drive system, so its control performance is directly related to the reliable and efficient operation of the drive motor, which will affect the power performance of the entire vehicle and the comfort of the passengers.
Q:What is the difference between inverter energy consumption braking and motor energy consumption braking?
Energy consumption braking is to rely solely on the motor to consume kinetic energy to achieve the purpose of parking. Therefore, the braking effect and accuracy are not ideal. In some occasions requiring short braking time and good braking effect, this brake is not normally used. Such as lifting machinery, its operation is characterized by low motor speed, frequent start, stop and reverse, and drag the weight of the operation. In order to achieve accurate and flexible control, the motor is often in a state of braking, and requires large braking torque. The energy consumption brake can not meet the above requirements. Therefore, lifting machinery generally adopts reverse braking, and requires mechanical braking, in case the weight is slipped during running or losing power.
Q:How to choose frequency converter?
Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics 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.
Q:What is the main harmonic produced by a transducer? How about the degree?
To reduce the influence of harmonics, various measures can be taken, but for the inverter, the main circuit is to install an AC reactor.The input side of the inverter generates the harmonic mechanism: for the inverter, as long as there is a rectifier circuit on the power supply side, it will produce harmonics caused by nonlinearity. Based on the three-phase bridge rectifier circuit for example, AC grid voltage for a sine wave, square wave AC input current waveform, the waveform, according to Fourier series can be decomposed into fundamental and harmonics, usually containing 6m + 1 (m=1,2) harmonics, the harmonics in power grid. A single fundamental wave, combined with several harmonic waves, is called an abnormal wave
Q:What does the RUN key on the inverter mean? How do you use it?
There are two conditions on the panel of the converter. There is one panel with FWD (positive turn), REV (reverse), and STOP (stop). There is also a panel, only the positive turn, just write RUN.
Q:What is the frequency converter through function?
Frequency converter is an ideal motor stepless speed regulating device. It is mainly used in three-phase and two-phase asynchronous motors. It has the advantages of small start-up current, smooth operation and complete protection facilities. The utility model is suitable for stepless speed regulation of various equipment.
