Note: In order to prevent electric shock, the motor and frequency converter must be grounded before use. • Do not install the incoming capacitor or surge suppressor, radio noise filter to the output of the frequency converter. This will lead to the failure of the frequency converter or the damage of the capacitor and surge suppressor. If any of the above equipment has been installed, please remove it immediately. When it is necessary to set a non fuse circuit breaker at the output end, please consult the manufacturer for the selection of non fuse circuit breaker. • With regard to electromagnetic wave interference, the input / output (main circuit) of the frequency converter contains high-frequency components, which may interfere with the communication equipment near the frequency converter (such as AM radio). Therefore, EMC filters are installed to minimize interference. • For details of peripheral devices, please refer to the user manual of each option and peripheral device. • PM motor cannot operate on power frequency power supply. • Because PM motor is a motor with built-in permanent magnet, even when the power supply of frequency converter is disconnected, as long as the motor is still rotating, high voltage will be generated at the motor terminal. When the output switch is closed, turn on the power supply of the frequency converter and use it when the motor is stopped.

Ig module is damaged due to poor heat dissipation The frequency converter makes a sudden sound during operation, and the external connection is burned. It is found that the IGBT module of the frequency converter is damaged after disassembly. Through the test of relevant boards, it is found that the IGBT trigger circuit is damaged, and other plates are normal. When removing the frequency converter board, it was found that there were a lot of oil and dust on the power board and current detection board. Turn on the fan of the heat sink of the frequency converter and see that the heat sink is also covered with oil and sundries, which completely blocks the heat dissipation channel of the frequency converter. It is inferred that the Ig module of the frequency converter is damaged due to poor heat dissipation. Maintenance process: first, completely disassemble the frequency converter, remove the heat sink of the heat dissipation channel, clean the heat sink with air pressure gas, and clean all the internal structural parts and boards of the frequency converter. Install the IGBT module. When installing the IGBT module, install it in sequence according to the requirements of the module, with appropriate torque. Repair the trigger circuit, and then install other devices in turn. After installation, conduct static test. After the static test results are good, conduct power on test and load test. The on load test is qualified and the maintenance is completed successfully. Experience summary: Based on the maintenance of several frequency converters in different models and different use environments, it is concluded that the main reason for the damage of frequency converter IGBT module is the poor use environment, which leads to the damage of electronic components on gate drive card and the blockage of heat dissipation channel of frequency converter* The easily damaged devices are voltage stabilizing tube and optocoupler. Check whether there is a problem in the driving circuit. Compare whether the resistance of each trigger terminal is consistent when power is off. The voltage waveform at the trigger end can be measured after power on. However, some frequency converters cannot be started without being installed into the module. At this time, a false load is connected in series at the p-end of the module to prevent the module from being burnt out due to touching the originator or other lines by mistake during inspection. Another important part of NTK's overall development environment is ABB automation builder tool suite. This provides an integrated development environment for various automation components used in control system projects such as NTK - from PLC, safety PLC and motion controller to driver and HMI. The tool significantly reduces software complexity and time to market. Knud Jansen, manager of mechanical control and automation products in ABB's automation products division, said: "this application illustrates the simplicity of PLC users using PLC based safety control system architecture. The key drivers of NTK are the ability to program in high-level structured text language and powerful safety code analyzer tools - providing immediate feedback to software developers when developing and testing PLC code modules." The PLC crane control system of NTK is installed in the protected cabinet in the cab. However, an "extreme condition" version of the PLC is also available, enabling users to configure enhanced functional safety PLC solutions for harsh conditions and extreme weather, such as those commonly used in some crane and winch applications. Working principle of AC servo motor The rotor inside the servo motor is a permanent magnet. The U / V / W three- phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder feedback signal of the motor is sent to the driver. The driver compares the feedback value with the target value to adjust the rotation angle of the rotor. The accuracy of the servo motor depends on the accuracy of the encoder (number of lines). 4. Servo motor? How many types? What are the characteristics of the work? A: servo motor, also known as executive motor, is used as an executive element in the automatic control system to convert the received electrical signal into angular displacement or angular speed output on the motor shaft. It is divided into DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation, and the speed decreases at a uniform speed with the increase of torque, What are the functional differences between AC servo motor and brushless DC servo motor? AC servo is better because it is controlled by sine wave and the torque ripple is small. DC servo is trapezoidal wave. But DC servo is relatively simple and cheap. Since the 1980s, with the development of integrated circuit, power electronics technology and AC variable speed drive technology, permanent magnet AC servo drive technology has made outstanding development. Electrical manufacturers in various countries have launched their own AC servo motor and servo driver series products, which have been continuously improved and updated. AC servo system has become the main development direction of contemporary high- performance servo system, which makes the original DC servo face the crisis of being eliminated. Since the 1990s, the digital servo motor drive system has been used all over the world. The development of AC servo drive in the field of transmission is changing with each passing day. Compared with DC servo motor, permanent magnet AC servo motor has the following main advantages: (1) there is no brush and commutator, so it works reliably and has low requirements for maintenance. ⑵ the heat dissipation of stator winding is convenient. ⑶ small inertia, easy to improve the rapidity of the system. (4) it is suitable for high-speed and large torque working state. (5) smaller volume and weight under the same power.

DC reactor, also known as smoothing reactor, is mainly used on the DC side of converter and is widely used in general frequency converter. There is a DC current with AC component flowing through the reactor. The main purpose is to limit the AC component superimposed on the DC current to a specified value, keep the rectifier current continuous, reduce the current ripple value, improve the input power factor, and suppress the harmonic generated by the converter. effect DC reactors are connected in series on each pole of the converter station. The inductance is about 0.4 ~ 1.0h. Its main functions are as follows: (1) Prevent inverter commutation failure. (2) Reduce voltage and current harmonics in DC lines. (3) Reduce ripple coefficient. (4) Limit the current in the rectifier when the line is short circuited. However, it should be noted that the value of inductance must ensure that the DC circuit does not resonate at power frequency. DC reactor can increase the power factor to more than 0.9. Because of its small size, many frequency converters have installed DC reactors directly in the frequency converter. In addition to improving the power factor, the DC reactor can also weaken the impact at the moment when the power supply is just connected. If AC reactor and DC reactor are equipped at the same time, the power factor of variable frequency speed regulation system can be increased to more than 0.95. Structural design The DC smoothing reactor is used for the filter circuit at the output side of the rectifier circuit. Because there is a DC current component, the magnetic flux of the iron core works in the first quadrant, resulting in magnetic bias. In order to increase the inductance and prevent magnetic flux saturation, DC smoothing reactors adopt cut iron core and add air gap to lengthen their hysteresis loop laterally, which is a bit like the case of single ended flyback transformer in principle. In this way, when there is a current of the same size, B is small and not easy to be saturated. Four factors should be considered in the structural design of open core reactor: 1) The DC component I of the current flowing through the reactor, that is, the average value of the inductive current IL, determines the cross-sectional area of the winding conductor and the heating of the winding. 2) The peak to peak value of AC current component is expressed by △ IPP or abbreviated as △ I, which is determined by the continuity requirements of inductive current. Generally, without affecting the output voltage ripple, twice the minimum load current ilmin output by the rectifier filter circuit is the peak to peak of the required filter inductance current change. Thus: △ IPP = 2ilmin 3) The inductance L required by the filter circuit is determined by the frequency of AC current component and peak to peak △ IPP. It is an intermediate calculated value in the process of reactor structure design, rather than the primary factor to be considered in advance. 4) Power loss and temperature rise are factors that need to be considered in advance in the process of reactor structure design. There are more than one method to design DC smoothing reactor, and these methods are unified with each other. A simple, clear and practical engineering design method is introduced here. Its steps are as follows: (1) Calculated energy storage We know that if the inductance of the reactor is l and the current is I, the stored energy is W=1/2LI Because the highest flux density BM is determined by the maximum current in the reactor, I in the formula should be calculated according to the maximum current. If the DC current is I, the peak to peak value of AC current is △ IPP. (2) Select the material of iron core According to the proportion of AC component △ I in I, the frequency of AC component and the index requirements of inverter on its output noise, the material of reactor core can be selected. After the material is selected, the maximum flux density BM and the effective coefficient K of iron core section can be determined. Note that when selecting BM, it is generally required to leave a large margin, because the reactor is not saturated after half an inverter cycle of output short circuit (i.e. a normal rectifier cycle), so as to make the protection circuit act, so as to improve the working reliability of the inverter circuit. (3) Select the shape of the iron core and determine the window utilization coefficient KC According to the material, winding process and installation structure of the selected iron core, the shape of the iron core is selected, and then the type of conductor is selected according to the current level to determine the window utilization coefficient KC. (4) Select conductor current density coefficient kJ and current density J According to the heat dissipation conditions, the required copper consumption, the shape of the iron core and the allowable temperature rise of the wire package, select the appropriate current density coefficient kJ (refer to table 4.2) and the current density J of the conductor. (5) Calculate the cross-sectional area of the wire and select the wire The cross-sectional area of the conductor is calculated by the following formula: S = I / J; Then select the shape and size of the wire. (6) Calculate the number of winding turns When calculating the number of turns of reactor winding, we should consider making full use of the window area of iron core, so as to maximize the number of turns and leave a certain margin for BM.

Proximity switches are widely used in aviation, aerospace technology and industrial production. It is used in daily life, such as automatic doors in hotels, restaurants and garages and automatic hot air fans. In terms of security and anti-theft, important places such as data archives, finance and accounting, finance, museums and treasuries are usually equipped with anti- theft devices composed of various proximity switches. In measurement technology, such as length and position measurement; In the control technology, such as the measurement and control of displacement, velocity and acceleration, a large number of proximity switches are also used.

Three wire proximity switch is divided into NPN type and PNP type, and their wiring is different. See the figure below: 2) The wiring of the two-wire proximity switch is relatively simple. The proximity switch can be connected to the power supply after being connected in series with the load. 3) Wiring of three wire proximity switch: the red (brown) wire is connected to the positive end of the power supply; The blue line is connected to the 0V end of the power supply; The yellow (black) line is a signal and should be connected to the load. The other end of the load is connected in this way: for NPN proximity switch, it should be connected to the positive end of the power supply; For PNP type proximity switch, it shall be connected to the 0V end of the power supply. 4) The load of proximity switch can be signal lamp, relay coil or digital input module of PLC. 5) Special attention should be paid to the type selection of three wire proximity switch connected to PLC digital input module. PLC digital input modules can generally be divided into two types: one type of common input terminal is the power supply 0V, and the current flows out of the input module (Japanese mode). At this time, NPN proximity switch must be selected; The other type of common input is the positive end of the power supply, and the current flows into the input module, i.e. well input (European mode). At this time, PNP type proximity switch must be selected. Don't make a mistake. 6) The two-wire proximity switch is limited by the working conditions. When it is turned on, the switch itself produces a certain voltage drop, and when it is cut off, there is a certain residual current flowing. It should be considered when selecting. Although the three wire proximity switch has one more wire, it is not troubled by adverse factors such as residual current and works more reliably. 7) Some manufacturers lead out the "normally open" and "normally closed" signals of the proximity switch at the same time, or add other functions. In this case, please make specific wiring according to the product manual. Slot type photoelectric switch wiring The diode of the photoelectric switch is a light-emitting diode, the output is a photosensitive triode, C is the collector, and E is the emitter. When a triode is used as a switch, the collector is usually used as the output. General connection method: the diode is the input end, e is grounded, C is connected to the load, and the other end of the load needs to be connected to the positive power supply. This connection method has a wide range of application. Special connection method: the diode is the input end, C is connected to the positive power supply, e is connected to the load, and the other end of the load needs to be grounded. This connection method is only applicable when the load equivalent resistance is very small (within tens of ohms). If the load equivalent resistance is relatively large, the working point of the switching triode may be abnormal, resulting in unreliable switching operation. In general industrial production sites, eddy current proximity switches and capacitive proximity switches are usually selected. Because these two proximity switches have low requirements for the environment. When the measured object is a conductive object or an object that can be fixed on a metal object, eddy current proximity switch is generally selected because of its high response frequency, good anti-environmental interference performance, wide application range and low price. If the measured object is non-metal (or metal), liquid level height, powder height, plastic, tobacco, etc. Capacitive proximity switch shall be selected. This kind of switch has low response frequency but good stability. The influence of environmental factors shall be considered during installation. If the measured object is made of magnetic conducting material or the magnetic steel is buried in the measured object in order to distinguish the object moving with it, hall proximity switch shall be selected, and its price is the lowest. Photoelectric proximity switches can be used in occasions with good environmental conditions and no dust pollution. When the photoelectric proximity switch works, it has almost no effect on the measured object. Therefore, it is widely used in fax machines with high requirements and tobacco machinery. In the anti-theft system, the automatic door usually uses pyroelectric proximity switch, ultrasonic proximity switch and microwave proximity switch. Sometimes, in order to improve the reliability of identification, the above proximity switches are often used in combination.

Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, power distribution and power consumption. Broadly speaking, contactor refers to an electrical appliance that uses the current flowing through the coil to generate a magnetic field and close the contact in order to control the load. main features The AC contactor uses the main contact to open and close the circuit and the auxiliary contact to turn on the control circuit. The main contact is generally normally open contact, while the auxiliary contact often has two pairs of normally open contact and normally closed contact. Small contactors are often used as intermediate relays to cooperate with the main circuit. The contact of AC contactor is made of silver tungsten alloy, which has good conductivity and high temperature ablation resistance. The power of AC contactor action comes from the magnetic field generated by AC through the coil with iron core. The electromagnet core is composed of two "mountain" shaped young silicon steel sheets. One of the fixed iron core is sleeved with coil, and the working voltage can be selected. In order to stabilize the magnetic force, a short-circuit ring is added to the suction surface of the iron core. After the AC contactor loses power, it returns by spring. The other half is a movable iron core, whose structure is the same as that of a fixed iron core, which is used to drive the closing and breaking of the main contact and auxiliary contact. Contactors above 20 amps are equipped with arc extinguishing cover, which can quickly break the arc and protect the contact by using the electromagnetic force generated when the circuit is disconnected. The contactor can operate at high frequency. When it is used as the power on and off control, the maximum operation frequency can reach 1200 times per hour. The service life of contactors is very long. The mechanical life is usually millions to 10 million times, and the electrical life is generally hundreds of thousands to millions of times. working principle The working principle of the contactor is: when the contactor coil is energized, the coil current will generate a magnetic field. The generated magnetic field causes the static iron core to generate electromagnetic suction to attract the moving iron core, and drives the AC contactor to act. The normally closed contact is disconnected and the normally open contact is closed. The two are linked. When the coil is powered off, the electromagnetic suction disappears, and the armature is released under the action of the release spring to restore the contact, open the normally open contact and close the normally closed contact. The working principle of DC contactor is a little similar to that of temperature switch.

Circuit breaker refers to the switching device that can close, carry and disconnect the current under normal circuit conditions, and can close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low- voltage circuit breakers according to their scope of use. The division of high- voltage and low-voltage boundaries is relatively vague. Generally, those above 3KV are called high-voltage appliances. The circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, and protect the power line and motor. When they have serious overload, short circuit, undervoltage and other faults, it can automatically cut off the circuit. Its function is equivalent to the combination of fuse switch and over and under heating relay. Moreover, it is generally not necessary to change the parts after breaking the fault current. At present, it has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is an electrical appliance with large amount and wide range of use. working principle The circuit breaker is generally composed of contact system, arc extinguishing system, operating mechanism, release, shell, etc. In case of short circuit, the magnetic field generated by large current (generally 10 to 12 times) overcomes the reaction spring, the release pulls the operating mechanism to act, and the switch trips instantaneously. In case of overload, the current increases, the calorific value intensifies, and the bimetallic sheet deforms to a certain extent to promote the action of the mechanism (the greater the current, the shorter the action time). For the electronic type, the transformer is used to collect the current of each phase and compare it with the set value. When the current is abnormal, the microprocessor sends a signal to make the electronic release drive the operating mechanism. The function of circuit breaker is to cut off and connect the load circuit and cut off the fault circuit to prevent the expansion of accident and ensure safe operation. The high-voltage circuit breaker needs to break the arc with 1500V and current of 1500-2000a. These arcs can be elongated to 2M and still continue to burn. Therefore, arc extinguishing is a problem that must be solved for high voltage circuit breaker. The principle of arc blowing and arc extinguishing is mainly to cool the arc and reduce heat dissociation. On the other hand, arc blowing lengthens the arc to strengthen the recombination and diffusion of charged particles, and blow away the charged particles in the arc gap to quickly restore the insulation strength of the medium. Low voltage circuit breaker, also known as automatic air switch, can be used to turn on and off load circuit, and can also be used to control infrequently started motor. Its function is equivalent to the sum of some or all functions of knife switch, overcurrent relay, voltage loss relay, thermal relay and leakage protector. It is an important protective appliance in low-voltage distribution network. Low voltage circuit breaker has many protection functions (overload, short circuit, undervoltage protection, etc.), adjustable action value, high breaking capacity, convenient operation, safety and other advantages, so it is widely used. Structure and working principle low voltage circuit breaker is composed of operating mechanism, contact, protection device (various releases), arc extinguishing system, etc. The main contact of low-voltage circuit breaker is closed manually or electrically. After the main contact is closed, the free tripping mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply. In case of short circuit or serious overload of the circuit, the armature of the overcurrent release is pulled in to make the free tripping mechanism act, and the main contact disconnects the main circuit. When the circuit is overloaded, the thermal element of the thermal release generates heat, which bends the bimetallic sheet and pushes the free release mechanism to act. When the circuit is under voltage, the armature of the under voltage release is released. It also makes the free tripping mechanism act. The shunt release is used for remote control. During normal operation, its coil is powered off. When distance control is required, press the start button to power on the coil.
