Variable Frequency Drive

What is VFD?

Are the inverter and VFD the same?

A variable frequency drive (VFD) is a type of electric motor driven by a motor controller, which is supplied to the electric motor by changing the frequency and voltage. Other names of VFD are variable speed drive, variable speed drive, variable frequency drive, AC drive, micro drive and inverter.

Frequency (or Hertz) is directly related to the speed of the motor (RPM). In other words, the faster the frequency, the faster the RPM. If the application does not require the motor to run at full speed, the VFD can be used to reduce the frequency and voltage to meet the requirements of the motor load. As the application program changes the motor speed requirements, the VFD can simply increase or decrease the motor speed to meet the speed requirements.

How does a variable frequency drive work?

The first stage of a variable frequency AC drive or VFD is a converter. The converter consists of six diodes, similar to the check valve used in the piping system. They only allow current to flow in one direction. The direction indicated by the arrow in the diode symbol. For example, as long as the A-phase voltage (voltage similar to the pressure in a pipe system) is more positive than the B-phase or C-phase voltage, the diode will open and allow current to flow. When Phase B becomes more positive than Phase A, the Phase B diode will turn on and the Phase A diode will turn off. The same is true for the three diodes at the cathode of the bus. Therefore, when each diode turns on and off, we get six current “pulses”. This is called “six-pulse VFD”, which is the current standard configuration of variable frequency drives.

Let us assume that the drive is running on a 480V power system. The 480V rating is “rms” or root mean square. The peak value on the 480V system is 679V. As you can see, the DC voltage of the VFD DC bus has AC ripple. The voltage is approximately between 580V and 680V.

We can eliminate the AC ripple on the DC bus by adding a capacitor. Capacitors operate similarly to reservoirs or accumulators in a pipeline system. The capacitor absorbs AC ripple and provides a smooth DC voltage. The AC ripple on the DC bus is usually less than 3 volts. Therefore, the voltage on the DC bus becomes “approximately” 650VDC. The actual voltage will depend on the voltage level of the AC line supplying the drive, the voltage imbalance level on the power system, the motor load, the impedance of the power system, and any reactors or harmonic filters on the drive.

A diode bridge converter that converts alternating current to direct current is sometimes simply called a converter. The converter that converts direct current back to alternating current is also a converter, but to distinguish it from a diode converter, it is usually called an “inverter.” In the industry, it has become common to refer to any DC-AC converter as an inverter. When we turn off one of the top switches of the inverter, this connection of the motor is connected to the positive DC bus, and the voltage on this phase becomes positive.

When we close one of the bottom switches in the converter, that phase will be connected to the negative DC bus and become negative. Therefore, we can make any phase on the motor positive or negative at will, so that any frequency we need can be generated. Therefore, we can make any phase positive, negative or zero.

Please note that the output of the VFD is a “rectangular” waveform. VFD will not produce sinusoidal output. For general distribution systems, this rectangular waveform is not a good choice, but it is completely suitable for electric motors.

If you want to reduce the motor frequency to 30 Hz, you only need to switch the inverter output transistor more slowly. However, if the frequency is reduced to 30Hz, the voltage must also be reduced to 240V to maintain the V/Hz ratio (for this, please refer to the introduction of VFD motor theory). If we only have 650VDC, how can we reduce the voltage?

This is called pulse width modulation or PWM. Imagine that we can control the pressure in the water pipeline by opening and closing valves at high speeds. Although this is impractical for piping systems, it works well for VFDs. Please note that in the first half of the cycle, the voltage is on for half of the time and off for half of the time. Therefore, the average voltage is 480V or half of 240V. Through the output pulse, we can obtain any average voltage on the output of the VFD.

Why use VFD?

1- Reduce energy consumption and energy costs
If your application does not need to run at full speed, you can reduce energy costs by using a variable frequency drive to control the motor, which is one of the advantages of a variable frequency drive. VFD allows you to match the speed of electric equipment to load requirements. No other AC motor control method can achieve this goal.
Today, motor systems account for more than 65% of industrial energy consumption. By installing or upgrading to a VFD to optimize the motor control system, the energy consumption of the factory can be reduced by up to 70%. In addition, the use of VFD improves product quality and reduces production costs. Combining energy efficiency tax incentives and utility rebates, the return on investment of VFD installations can be as short as 6 months.

2- Increase production through stricter process control
By running the motor at the most efficient speed for your application, you can reduce the occurrence of errors, thereby increasing the level of production and thus earning higher revenue for the company. On conveyors and belts, you eliminate jitter at start-up, thereby achieving high throughput.

3- Extend equipment life and reduce maintenance
When the equipment is controlled by a VFD to ensure the best motor application speed, the service life of the equipment will be longer, and downtime will be reduced due to maintenance. Since the VFD can optimally control the frequency and voltage of the motor, the VFD will provide better protection for the motor from electric thermal overload, phase protection, undervoltage, overvoltage and other problems. The motor or driving load will not be subjected to the “instantaneous shock” when the entire line is started, but it can start smoothly, thereby eliminating the wear of belts, gears and bearings. This is also an excellent way to reduce and/or eliminate water hammer, because we can achieve smooth acceleration and deceleration cycles.

Which motors can the inverter control

Variable-frequency Drive, VFD is a power control device that uses variable frequency technology and microelectronics technology to control AC motors by changing the frequency of the motor’s working power supply. The frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro processing unit. The inverter adjusts the voltage and frequency of the output power supply by opening and closing the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions. , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency converters have also been widely used.
The inverter can control:

General purpose motors

This is used in occasions where torque removal, speed and accuracy are not required.
Used on the fan and water pump, it has good energy saving and automatic control effect

Vector control inverter

Generally used to control the frequency conversion special motor can also be a general-purpose motor
Vector control features have good control over large torque, load changes, and angular velocity accuracy on speed

Servo-controlled inverter

Generally used to control frequency conversion special motors. Compared with vector, it has better control function and control effect. Of course, it is more complicated.

How does the inverter change the frequency

The inverter converts direct current to alternating current through an inverter circuit Change the output frequency and voltage by triggering the frequency of the IGBT and the size of the conduction angle

How is VFD connected to PLC?

The inverter can be connected to the PLC via Rs485 or Ethernet, so you need to consult whether it supports it before purchasing.

How to save energy during the work of the inverter?

The inverter realizes energy saving by feeding back to the grid.

There are two working modes of motor work: electric and brake. When the motor is braking, it is equivalent to a generator, and the inverter realizes energy saving by feeding back the electric energy generated by the motor to the grid for utilization.

Although the energy feedback of a single motor has a small contribution to energy saving, there are often a large number of motors working in a factory, and the power is large. In this way, the electrical energy of these motors’ braking turntables is collected and fed back to the grid for further processing. Utilization can save a lot of energy.

Does the variable frequency drive damage the motor?

The damage of the inverter to the motor includes two aspects, the damage of the stator winding and the damage of the bearing. This kind of damage usually occurs within a few weeks to more than ten months. The specific time depends on the brand of the inverter, the brand of the motor, the power of the motor, the carrier frequency of the inverter, the length of the cable between the inverter and the motor, and the ambient temperature. Many factors are related. The early accidental damage of the motor brings huge economic losses to the production of the enterprise.
This loss is not only the cost of motor repair and replacement, but also the economic loss caused by unexpected shutdown. Therefore, when using a frequency converter to drive a motor, sufficient attention must be paid to the problem of motor damage.

How many motors can one frequency converter control?

If the motors are connected in parallel, please note that it depends on the power of the inverter.

If the controlled motors all work separately, only one can be controlled

How to choose the right inverter for the motor

When we select the inverter, we need to follow the type of the controlled object, speed range, static speed accuracy, starting torque, etc., so that it meets the process and production requirements while being easy to use and economical.
The general experience is that the size of the motor should be the size of the inverter, and sometimes the size can be larger.   
The power factor of the high-power inverter is lower, it is better to install an AC reactor at the input end of the inverter. One is to improve the power factor, and the other is to suppress high-frequency harmonics. If you frequently start and brake frequently, install a brake unit and a brake resistor.   

If you need to reduce noise, you can choose a water-cooled inverter;

If braking is required, a braking chopper and braking resistor are required. Or you can choose four-quadrant products, which can feed back energy to the grid and save energy;   

If there is only a DC power supply on site, you can choose a pure inverter product (using a DC power supply) to drive the motor.

The final basis for the selection of the inverter is that the current curve of the inverter includes the current curve of the mechanical load.

How to control the inverter?

There are three ways to operate the inverter without an external controller (such as PLC):
① Use the buttons on the operation panel;
②Operate the components connected to the terminal (such as buttons and potentiometers);
③Composite operation (such as setting the frequency on the operation panel, operating the button connected to the terminal block for start/stop control).
In order to facilitate operation and make full use of the inverter, PLC can also be used to control the inverter

Can the speed of the inverter exceed the maximum speed of the motor?

Install a frequency converter before the motor, and change the frequency of the motor’s input power supply through the frequency converter to change the motor speed. Because changing the power frequency changes the speed of the rotating magnetic field, it also changes the synchronous speed of the motor.

Plasma Cutting Machine

Plasma arc cutting machine is an efficient metal cutting equipment.

Principle of plasma cutting

Its working principle is to use compressed air as the ionizing medium, and use the compression of the cutting gun nozzle to form a high-density plasma arc heat source to melt the metal, and at the same time use a high-speed airflow to blow away the melted metal to form a narrow slit. Metal is melted quickly.

Use of plasma cutting machine

The plasma cutting machine can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, carbon steel, etc., not only the cutting speed is fast, the slit is narrow, the cut is flat, the heat affected zone is small, the deformation of the workpiece is low, the operation is simple, and it has significant The energy-saving effect.

Plasma cutting machines are used in the manufacture, installation and maintenance of various machinery and metal structures, as well as cutting, opening, digging, and beveling of middle and thin plates.


The plasma cutting machine with different working gases can cut all kinds of metals that are difficult to cut by oxygen, especially for non-ferrous metals (stainless steel, carbon steel, aluminum, copper, titanium, nickel). The cutting effect is better; its main advantage is that the cutting thickness is not For large metals, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times that of oxygen cutting, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat-affected zone.
Plasma cutting machine, the available working gas (working gas is the conductive medium of the plasma arc, it is also the heat-carrying body, and at the same time the molten metal in the incision must be removed) has obvious effects on the cutting characteristics, cutting quality and speed of the plasma arc. influences. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.
Plasma cutting machines are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, steel structures and other industries!
Through the safe, simple, effective, multi-functional and environmentally friendly method of obtaining plasma from water vapor, thermal processing (cutting, welding, brazing, quenching, spraying, etc.) of metal with a thickness of 0.3 mm or more is carried out. It is the first in the history of the processing industry.

About the use of plasma cutting machine

How to use plasma cutting machine

  1. When the plasma cutting machine is in use, the flow rate of the air compressor should be greater than 0.3 cubic meters per minute, and the working pressure range is between 0.4 and 0.8 MPa.
  2. When using arc ignition to cut the plate, start the arc from the edge of the workpiece. If you want to cut from the middle of the plate, you need to drill a small hole in the middle first, and then start the arc from the edge of the small hole.
  3. Turn on the power switch for a period of time before cutting, and let the air flow circulate for a period of time so that the condensed water vapor in the cutting torch can be removed.

Classification of plasma cutting machines

The characteristics of the plasma cutting machine are fast cutting speed, narrow slit, flat cut, small heat-affected zone, low workpiece deformation, simple operation, and significant energy saving effect. This equipment has a wide range of applications in various industries, such as the manufacturing, installation and maintenance of various machinery and metal structures, as well as cutting, drilling, digging, and beveling of middle and thin plates. Since the plasma cutting machine is used with working gas, many plasma cutting machines are equipped with numerical control systems, so they are also called air plasma cutting machines or numerical control plasma cutting machines.

According to the different cutting methods, the plasma cutting machine is divided into different cutting types. The following Wuhan Linghang CNC company will briefly explain for you:

  1. Restrict plasma arc cutting.
    According to the re-constraint method of plasma arc, it is mainly divided into water re-tightening plasma arc cutting and magnetic field re-constraining plasma arc cutting. As the plasma arc is compressed again, its current density and the energy of the cutting arc are further concentrated, thereby improving the cutting speed and processing quality.
  2. Ordinary plasma arc cutting.
    According to the main working gas used, it is mainly divided into argon plasma arc cutting and oxygen plasma arc cutting. There are several types of oxygen plasma arc cutting and air plasma arc cutting. Cutting current is generally at 100
    Below A, the cutting thickness is less than 30mm.
  3. Precision plasma arc cutting.
    Plasma arc current density is very high, usually several times that of ordinary plasma arc current density. Due to the introduction of technologies such as rotating magnetic field, the stability of the arc has also been improved, so its cutting accuracy is quite high. The appearance quality of foreign precision plasma cutting has reached the lower limit of laser cutting, and its cost is only one-third of that of laser cutting.

The difference between contact and non-contact plasma cutting machine

The subject is different

(1) Contact type: ordinary plasma cutting machine, using the heat of high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the incision of the workpiece, and use the momentum of the high-speed plasma to remove the molten metal to form an incision. .

(2) Non-contact type: the portable plasma cutting machine adopts the plasma cable square tube structure, which realizes the integrated design of plasma cable and mechanical cross arm, and provides necessary conditions for optimizing the reasonable layout of processing equipment on the construction site.

Different features

(1) Contact type: fast cutting speed and high precision. The cutting opening is small, neat and without slag drop. On the basis of the traditional numerical control system, the control method for cutting is improved to avoid secondary trimming processing.

(2) Non-contact: The humanized frontal man-machine dialogue design facilitates the user’s control of the equipment, and the split structure design of the host and the cross arm is adopted, which greatly facilitates the production, transportation and Packaging required.

Different advantages

(1) Contact type: When cutting metals with small thickness, plasma cutting speed is fast, especially when cutting ordinary carbon steel thin plates, the speed can reach 5-6 times that of oxygen cutting method, the cutting surface is smooth and the thermal deformation is small , There is almost no heat affected zone.

(2) Non-contact type: expandable 4-axis linkage function, dynamic graphic display, 1-8 times graphic zoom, automatic tracking of moving points, U disk reading program and timely software upgrade, built-in rich and practical graphic library, Make programming easy to learn.

How to use plasma cutting machine is the correct way

Incorrect use will shorten the life of the plasma cutting machine. How to use it correctly is actually very simple.

  1. In order to reduce energy consumption and improve the use time of nozzles and electronic electrodes, when cutting small workpieces, “low speed” cutting should be used as much as possible. The cutting efficiency and accuracy of our Huafei cutting machine at low speed is higher than that of other similar brands , It is easy to cut through the workpiece without affecting the normal progress.
  2. When the “cutting thickness” button is set to “high level”, contact cutting should not be used (except under special circumstances). Underwater cutting can be considered, which can prevent dust and maintain cutting stability.
  3. If you must change the “cutting thickness” range, you must first turn off the main switch to avoid damage to the machine. This is particularly important. Safe use of electricity is a basic common sense.
  4. When disassembling, assembling or moving the equipment, please make sure to turn off the power before proceeding to avoid accidents. Cutting equipment is a precision instrument with many precision accessories. If it is disassembled and moved when the power is on, it will easily cause voltage instability or short-circuit conditions, resulting in unrecoverable accidents.
  5. Cut from the edge as much as possible instead of piercing and cutting. Starting from the edge will improve friction life. The most correct path is to point the nozzle directly at the edge of the equipment before the plasma arc starts, and then cut. This can ensure the arc stability of the cutting edge
  6. Do not overload the nozzle. Overloading of the nozzle can easily cause damage to the nozzle (overload means that the working current of the nozzle is too large). The current intensity should be 95% of the normal working current of the current nozzle. For example, the current current of a 100A nozzle should be set to 95A. Do not set too small, resulting in too low efficiency.
  7. After cutting, the metal must be cut through, and then move at an even speed to keep the movement stable, otherwise the nozzle will be damaged. And too fast or too slow cutting speed will affect the cutting quality.
  8. When not cutting the workpiece, press the torch button as little as possible to avoid damage to the machine. During the use of the equipment, it is easy to affect the equipment due to high temperature or environmental pollution. The equipment should be kept as clean as possible to reduce frequent useless operations and increase the service life.
  9. After the workpiece is completely cut, please be sure to turn off the power switch and the air supply valve to avoid affecting the reuse. It will stop when it is used up and the power will be cut off. This is the most important factor in the use of our equipment.

    To check the input and output of the signal, see if there is a fault signal. If not, you can continue.
  5. Load processing program
    Before the engraving machine officially enters the working state, the operator must first load the processing program. If the processing program is not loaded correctly, the machine will not be able to run the automatic processing function.
    Click “File F”-“Open and Load O” and an operation dialog box will pop up, in which we select the file to be processed. Or you can right-click the mouse in the automatic processing window, a shortcut menu will pop up, select “Open and Load” in the dialog box, we select the file to be processed. After selecting, click the button to open, and the processing program can be loaded into the system normally. At this time, click “Auto” to view the currently selected processing program.

  6. Daily maintenance of woodworking engraving machine
  7. Try to ensure that the continuous operation time is within 10 hours every day. The cooling water should be kept clean. At the same time, the water pump should be able to work normally. The water shaft motor must not be lack of water. At the same time, pay attention to the regular cooling Replace the water to avoid excessive water temperature. The temperature in winter is low, at this time we can replace the water in the tank with antifreeze.
  8. After each use of the machine, do not forget to clean it. There may be dust on the transmission system. Be sure to clean it up. The platform fluid should be kept clean at ordinary times. The vibration system should be lubricated regularly every week. When carrying out lubrication and oiling, pay attention to the xyz optical axis uses engine oil, and the screw part uses high-speed grease. In winter, the weather is cold and the temperature is too low. We can clean the lead screw and polished rod with gasoline first, and then refuel, otherwise the machine will be dislocated due to excessive resistance.
  9. When doing maintenance and inspection for electrical parts, remember to cut off the power first, and wait until the monitor does not display and the indicator light of the main circuit power supply has gone out before proceeding.
    Regarding how to maintain the engraving machine, the above is some relevant knowledge compiled for everyone. Any machine should be maintained and maintained at the same time as it is used. This can increase work efficiency and extend the service life of the machine.

Detailed operation steps of engraving machine

Engraving machine operation steps

  1. Turn on Before turning on the machine, first make sure that all connections between the machine tool and the computer are normal, and then turn on the power supply of the machine tool and the computer. After the system is started, enter the NcstudioTM numerical control system.
  2. Mechanical reset (optional) This section is only involved in the machine tool with the function of returning to the mechanical origin and when necessary. If the machine tool supports the operation of returning to the mechanical origin, select the “Back to Mechanical Origin” menu. The machine tool will automatically return to the mechanical origin and correct the system coordinate system. In some cases, such as after the last normal shutdown, restarting and continuing the last operation, the user does not need to perform a mechanical reset operation. Because NcstudioTM system saves the current coordinate information when exiting normally. In addition, if the user confirms that the current location is correct, this operation may not be performed.
  3. Load the processing program Before processing, the user generally needs to load the program to be processed, otherwise, some functions related to automatic processing are invalid. Select “Open (F) | Open (O)…” menu, a standard Windows file operation dialog box will pop up, from which you can select the drive, path and file name where the file to be opened is located. After clicking the “Open” button, the processing program is loaded into the system. At this time, the user can press the F2 key to switch to the “processing program” window to view the current processing program.
  4. Manual operation Display manual operation interface Select the menu item “View (V) | Display manual interface (M)”, the parameter display window will display a manual operation interface through which you can manually operate the machine tool. Manual movement The machine tool can be moved manually through the corresponding keys on the numeric keypad of the computer. The NUMLOCK light on the small keyboard should be on at this time. The corresponding keys are: 6 ——— X axis positive direction 4 ——— X axis negative direction 8 ——— Y axis positive direction 2 ——— Y axis negative direction 9 ——— Z axis positive direction 1 ——— Z axis The combination of these keys in the negative direction and CTRL can realize manual high-speed movement of the machine tool. Increase/decrease depth Use the +/- keys on the keypad with the number keys to quickly increase or decrease the depth.
  5. Determine the origin of the workpiece. The origin of the X, Y, and Z coordinates in the processing program is the origin of the workpiece. Before processing, we need to associate the position with the actual position. The steps are: Manually move the machine tool X and Y to the desired origin position on the workpiece, select the “Set current point as workpiece origin” menu, or clear the coordinate value of the current position in the coordinate window, so that when the processing program is executed It starts processing at the current position. The above steps have completed the workpiece origin setting of the X and Y axes, but the workpiece origin setting of the Z axis requires more precise operation means. This system cooperates with machine tool hardware to provide Z-axis tool setting function. Select “Operation (O)|Automatic tool setting (E)…” function to complete automatic tool setting. After the above two steps, the origin of the processed workpiece has been determined.
  6. Perform automatic processing Automatic processing means that the machine tool automatically processes according to the selected processing program. Start automatic processing Select the “Operate (O)|Start or Continue (S)” menu item, and the machine tool will automatically start the automatic processing process from the first sentence of the processing program. Machine stop During automatic processing, if you want to stop the processing program, select the “Operation (O) | Stop (O)” menu item, and the machine tool will stop processing after the current statement is processed and enter the “Idle” state. This method is a method to make the system stop accurately and orderly, and it is also a recommended method. Note: When the high-speed smooth speed connection feature is valid, the system will stop when the connection speed is zero. The machine tool is in the process of automatic processing. In case of emergency, select the “Operation (O)|Emergency stop (B)” menu item, and the machine tool will stop processing immediately. If you want to restart processing, you must first select “Operation (O)| Emergency stop recovery (R)” menu and then select “Operation (O)|Start or Continue (S)” menu, the machine tool will restart the automatic processing process from the first sentence of the processing program, otherwise the machine tool will not work. When the machine tool pauses during automatic processing, if you need to pause processing, select the “Operation (O) | Pause (P)” menu item, and the machine tool will stop processing after executing the current processing statement. Select the “Operation (O) | Start or Continue (S)” menu item. Program skip execution. Select the “Advanced Start (A)” menu item, and a dialog box will pop up, asking you to execute from the first sentence of the program to the end of the program. If you fill in the sentence number, click “Start” “Key, the machine tool will only execute a certain sentence in the program according to your requirements. But there must be a segment number before executing this function program statement.
  7. Direct positioning function If you often want to locate a certain point quickly, you can try the “direct positioning function” function. The shortcut key to enter the “direct positioning function” function is F5, and the shortcut key to launch the “direct positioning function” function is Esc. Input the + sign before X in the “Direct Positioning Function” window to realize incremental input. Enter * in front of X in the “Direct Positioning Function” window to realize mechanical coordinate positioning. Enter the @ sign in front of the X in the “Direct Positioning Function” window to realize the function of correcting the workpiece origin (including increasing/decreasing depth).
  8. Shut down After the program processing is completed, turn off the power of the machine tool and the computer.
