Cooling mode of fr-e740-1.5k-cht: forced air cooling Selection method of fr-e740-1.5k-cht: 1. Fr-e740-1.5k-cht is selected according to the following load torque characteristics and is divided into the following three categories: (1) Constant torque load (2) Constant power load (3) Fluid load 2. Fr-e740-1.5k-cht is selected according to the control mode and is divided into the following five categories: (1) V / F open loop control (2) V / F closed loop control (3) Vector control without speed sensor (4) Vector control with speed sensor (5) Direct torque control Fr-e740-1.5k-cht selects the protective structure according to the use and installation environment: The protective structure of fr-e740-1.5k-cht should adapt to its installation environment, which requires consideration of environmental temperature, humidity, dust, pH, corrosive gas and other factors, which is of great significance to the long-term, stable, safe and reliable operation of fr-e740- 1.5k-cht. It is divided into the following four categories: (1) Open type (2) Closed type (3) Sealed type (4) Closed type 1. Select the frequency converter according to the load characteristics, If the load is constant torque load, Siemens MMV / MDV frequency converter shall be selected. If the load is fan and pump load, Siemens eco frequency converter shall be selected. 2. When selecting the frequency converter, the actual motor current value shall be used as the basis for the selection of the frequency converter, and the rated power of the motor can only be used as a reference. In addition, it should be fully considered that the output of the frequency converter contains high-order harmonics, which will deteriorate the power factor and efficiency of the motor. Therefore, the current of the motor increases by 10% and the temperature rise increases by about 20% compared with the power frequency power grid. Therefore, when selecting motor and frequency converter, this situation should be taken into account and appropriate allowance should be reserved to prevent excessive temperature rise from affecting the service life of motor. 3. If the frequency converter wants to run with a long cable, measures should be taken to restrain the influence of the long cable on the ground coupling capacitance to avoid insufficient output of the frequency converter. The frequency converter shall be selected by amplifying the first gear, or the output reactor shall be installed at the output end of the frequency converter. Shanghai Mitsubishi fr-e740-1.5k-cht 4. When the frequency converter is used to control several motors in parallel, the length of the motor cable and the allowable range of the frequency converter must be considered. If the specified value is exceeded, the frequency converter shall be selected by amplifying the first gear or the second gear. In addition, in this case, the control mode of the frequency converter can only be Vif control mode, and the frequency converter cannot protect the overcurrent and overload protection of the motor. At this time, it is necessary to add a fuse on each motor to realize the protection.

Function of braking resistance: 1 Protect the frequency converter; 2. Protect the power network. Braking resistance is a kind of ripple resistance, which is mainly used in the mechanical system of frequency converter controlling the rapid shutdown of motor. The firecracker motor converts the regenerative electric energy generated by the rapid shutdown into heat energy. The principle of resistance braking is that the rotor has current flow, which generates torque opposite to the rotation direction in the magnetic field of the stator, consumes the kinetic energy of the train, and achieves the purpose of braking. When the motor or other inductive load driven by the frequency converter stops, it is generally realized by energy consumption braking, that is, the kinetic energy of the motor and the magnetic energy in the coil are consumed through another energy consuming element after stopping, so as to realize rapid shutdown. Compent: Ceramic tube: it is the skeleton of alloy resistance wire and has the effect of radiator at the same time Alloy resistance wire: the flat belt has a wavy shape and is wound on the surface of the ceramic tube, which is responsible for converting the regenerated electric energy of the motor into heat energy The coating is flame-retardant on the surface of the alloy and has the characteristics of high temperature resistance Main hazards During the rapid shutdown of the motor, a large amount of regenerative electric energy will be generated due to inertia. If this part of regenerative electric energy is not consumed in time, it will directly act on the DC circuit part of the frequency converter. If it is light, the frequency converter will report fault, and if it is serious, the frequency converter will be damaged; The emergence of braking resistance solves this problem and protects the frequency converter from the harm of motor regenerative electric energy; Smooth operation The braking resistance directly converts the regenerative electric energy in the process of rapid braking of the motor into heat energy, so that the regenerative electric energy will not be fed back to the power network and will not cause grid voltage fluctuation, which plays a role in ensuring the smooth operation of the power network

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.

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.
