Q:What is the frequency converter through function?
Inverter through function refers to:The converter can temporary loss of power in the power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in state grid voltage recovery after the inverter can be immediately put into normal electric state.
Q:Can not directly through the PLC, ABB converter and Kingview software communication between them?
As long as there are 485 communications can be, the frequency converter manual on the MODBUS protocol, the address of each parameter, in the king view on the link can do, and I hope to adopt.
Q:What are the contents of frequency converter maintenance?
Regular maintenanceClean air filter, cooling air duct and interior dust. Check whether the screws, bolts and plug are loose, the input and output reactor ground and interphase resistance is short circuit, the normal should be more than tens of megabytes of europe. The conductor and insulator are corrosion phenomenon, if in time to wipe clean with alcohol. If the conditions permit, use the oscilloscope to measure the stability of the switching power supply output voltage, such as: 5V, 12V, 15V, 24V and other voltage. Is there any distortion in the square wave of the measuring circuit?. Is the UVW phase waveform sinusoidal?. The contact of a contactor whether traces the strike, serious to change with the same or greater than the original capacity of new products; confirm the correctness of the control voltage, the order of protection test; confirm that there is no abnormal loop protection; confirm the balance of the inverter output voltage in a single run time.
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:How about the quality of ABB converter?
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.
Q:What's the difference between universal inverter and fan pump converter?
In practice, the production machinery is often divided into three types: constant torque load, constant power load and fan, pump load.Constant torque load:The load torque TL is independent of the speed n, and the TL remains constant or almost constant at any speed. For example, conveyor belts, mixers, extruders and other friction loads, as well as cranes, hoists and other potential loads are constant torque load.When the inverter drives the load with constant torque, the torque at low speed is large enough and has enough overload capacity. If it is necessary to operate at a low speed, the cooling capacity of the standard asynchronous motor should be taken into consideration, so as to avoid the excessive temperature rise of the motor.
Q:What do you mean by the capacity of the inverter and the capacity of the motor?
That's not the case at all"Capacity" and "power" are essentially different. Usually we say that a large transformer capacity is how much KVA, but not to say how much KW, because the two are not the same thing
Q:What are the differences between the two quadrant and the four quadrant of the inverter?
The four quadrant inverter can not only drag the motor forward and backward, but also convert the kinetic energy of the motor idle time into electrical energy and feed it back to the power grid. Cause the motor to operate in the generator. Often used in some promotional occasions.
Q:What is the main function of the frequency converter on the machine tools?
CNC machine tool spindle drive system is also called the main transmission system, is to complete the main movement of the power unit part. The main shaft drive system is changed into the cutting moment and cutting speed of the tool or workpiece installed on the main shaft by the transmission mechanism, and the ideal parts are matched with the feed movement. It is one of the forming movement of parts processing, and its accuracy has a great influence on the machining accuracy of parts. Machine tool spindle drive and the drive is different, the machine spindle motion is usually rotation, unlike feed drive need wire rod or other linear motion device for reciprocating motion, NC cutter and workpiece by rotating the spindle and feed the cutting motion.
Q:How does the frequency converter fit the brake unit and the brake resistor?!
Using these kinetic energy, the brakes can be used, like the brakes of a car, by turning kinetic energy into heat energy to consume the kinetic energy of the motor shaftAnother way is to say that you use a braking unit with a set of braking resistors. The principle is to change kinetic energy into heat, and use electrical resistance to heat up the kinetic energy of the motor
