Q: What does 0L1 stand for?: Overload is excessive load, more than the equipment itself rated load, the phenomenon is that the current is too large, electrical equipment heating, long-term overload of the line will reduce the insulation level of the line, and even burned equipment or lines.

Q: What does the base frequency 60Hz represent in the inverter?: If the motor chooses a special AC frequency conversion motor, the motor is always marked with constant torque and constant power speed range. For example, Mark 5 ~ 100HZ for constant torque, 100 to 150HZ for constant power, the basic frequency should be set to 100HZ. The fundamental frequency parameter directly reflects the relationship between the output voltage and the output frequency of the inverter. If it is not set properly, it is easy to cause the overcurrent or overload of the motor. For example, an AC motor rated voltage 380V, rated frequency is 60HZ, if the frequency is lower than that of converter 60HZ V/F, a high proportion of the output voltage as high frequency, high output current, at startup, easy to cause the flow. If the frequency converter is set higher than 60HZ, low V/F ratio, the output voltage of the same frequency is low, the output current is low, at startup, can easily lead to the start and overload.

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: How can I learn the converter well?: If you are engaged in maintenance or after sale, you must know the main circuit diagram of the converter, rectifier, filter, inverter. Some electronic components must know, from the main circuit is frequently such as varistors, charging resistance, pressure resistance, no sense of capacitor, filter capacitor, driving circuit of multiple optocoupler such as 2503503120316, this is referred to as the optocoupler and the role, you must know the pin. Because the maintenance process should always be to determine the quality of the device.

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).

Q: What does Ro1c mean on a 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 does "frequency" in household appliances mean?: The air conditioner use frequency, enlarge the working range of the compressor, the compressor does not require intermittent running can be realized in cold and warm control, to reduce power consumption due to temperature changes, eliminate discomfort. In recent years, the new type of air conditioner has adopted brushless DC motor to realize variable frequency speed regulation, and its energy-saving effect is about 10% - 15% higher than that of AC asynchronous motor frequency conversion. In order to further improve the efficiency of the device,

Q: How to maintain the frequency converter will not damage, or regular maintenance?: Replacement of spare parts is a common maintenance method of general inverter, inverter composed of various components, some parts of the work for a long time after its performance will gradually decrease, aging, which is the main reason of inverter fault, in order to ensure the normal operation of equipment for a long time, the device should be replaced regularly:

Q: 5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?: Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.

Q: There is much dust and moisture in my workshop. Many brands are not durable.: ABB inverter is of high quality, but it requires a lot of environment, such as dust and humidity in your workshop. It is too bad for ABB inverters. You can try to use the seal of inverter, it is designed according to the use environment of inverter in various industries, mainly considering China's current converter relatively harsh environment (water vapor, dust, oil, metal powder, corrosive gas), in CNC lathe, grinding machine chemical plant, reaction kettle, blender, textile machinery, printing and dyeing equipment, water pump, industrial washing machine, dehydration machine where the effect is very good.
