9. Electronic thermal overload protection This function is set to protect the motor from overheating. It is used by the CPU in the Inverter to calculate the temperature rise of the motor based on the operating current value and frequency, thereby providing overheating protection. This function is only applicable to "one to one" situations, and in "one to many" situations, thermal relays should be installed on each motor. Electronic thermal protection setting value (%)=[Motor rated current (A)/Inverter rated output current (A)] × 100%.   10. Frequency limitations The upper and lower limits of the frequency output amplitude of the Inverter. Frequency limit is a protective function designed to prevent incorrect operation or failure of external frequency setting signal sources, which may cause excessive or low output frequency, in order to prevent damage to equipment. Set according to the actual situation in the application. This function can also be used for speed limiting. For some belt conveyors, due to the limited amount of material conveyed, in order to reduce mechanical and belt wear, an Inverter can be used for driving, and the upper frequency limit of the Inverter can be set to a certain frequency value, which can make the belt conveyor run at a fixed and lower working speed.   11. Bias frequency Some are also called deviation frequency or frequency deviation setting. Its purpose is to adjust the output frequency when the frequency is set by an external analog signal (voltage or current), and this function can be used to adjust the output frequency when the frequency setting signal is at its lowest. When the frequency setting signal of some Inverters is 0%, the deviation value can be applied within the range of 0 to fmax, and some Inverters (such as Mingdian House and Sanken) can also set the bias polarity. If during debugging, when the frequency setting signal is 0%, the output frequency of the Inverter is not 0Hz, but xHz, then setting the bias frequency to a negative xHz can make the output frequency of the Inverter 0Hz.   12. Frequency setting signal gain This function is only effective when setting the frequency using an external analog signal. It is used to compensate for the inconsistency between the external set signal voltage and the internal voltage of the Inverter (+10v); At the same time, it is convenient to select signal voltage for analog settings. When the analog input signal is at its maximum (such as 10V, 5V, or 20mA), calculate the frequency percentage that can output the f/V graph and set it as a parameter; If the external signal is set to 0-5V, and the output frequency of the Inverter is 0-50Hz, set the gain signal to 200%.   13. Torque limitation It can be divided into two types: driving torque limit and braking torque limit. It is based on the output voltage and current values of the Inverter, and torque calculation is carried out by the CPU. It can significantly improve the impact load recovery characteristics during acceleration, deceleration, and constant speed operation. The torque limiting function can achieve automatic acceleration and deceleration control. Assuming that the acceleration and deceleration time is less than the load inertia time, it can also ensure that the motor automatically accelerates and decelerates according to the torque setting value. The drive torque function provides powerful starting torque. During steady-state operation, the torque function controls the motor slip and limits the motor torque to the maximum set value. When the load torque suddenly increases, even if the acceleration time is set too short, it will not cause the Inverter to trip. If the acceleration time is set too short, the motor torque will not exceed the maximum set value. A high driving torque is beneficial for starting, and setting it at 80-100% is more appropriate. The smaller the braking torque setting value, the greater the braking force, which is suitable for situations of rapid acceleration and deceleration. If the braking torque setting value is set too much, overvoltage alarm phenomenon may occur. If the braking torque is set to 0%, the total amount of regeneration applied to the main capacitor can approach 0, so that the motor can decelerate to a stop without tripping when decelerating without using the braking resistor. However, on some loads, such as when the braking torque is set to 0%, there may be a brief idle phenomenon during deceleration, causing the Inverter to repeatedly start and the current to fluctuate significantly. In severe cases, it may cause the Inverter to trip, and attention should be paid.   14. Acceleration and deceleration mode selection Also known as acceleration/deceleration curve selection. Generally, Inverters have three types of curves: linear, nonlinear, and S, and most of them choose linear curves; Nonlinear curves are suitable for variable torque loads, such as fans; The S-curve is suitable for constant torque loads, and its acceleration and deceleration changes are relatively slow. When setting, the corresponding curve can be selected based on the load torque characteristics, but there are exceptions. When debugging the Inverter of a boiler induced draft fan, the author first selects a non-linear curve for the acceleration and deceleration curve, and when the Inverter is operated together, it trips. Adjusting and changing many parameters has no effect, and then changing it to an S curve will be normal. The reason for this is that before starting, the induced draft fan rotates on its own due to the flow of flue gas and reverses to become a negative load. This selects the S-curve, which slows down the frequency rise speed at the beginning of the start, thus avoiding the occurrence of Inverter tripping. Of course, this is the method used for Inverters without DC braking function for starting.   15. Torque Vector Control Vector control is based on the theory that asynchronous motors and DC motors have the same torque generation mechanism. Vector control method is to decompose the stator current into specified magnetic field current and torque current, and control them separately, while outputting the combined stator current to the motor. Therefore, in principle, the same control performance as a DC motor can be obtained. By using torque vector control function, the motor can output maximum torque under various operating conditions, especially in the low-speed operating area. Nowadays, almost all Inverters adopt non feedback vector control. Due to the ability of Inverters to compensate for slip based on the magnitude and phase of the load current, the motor has very hard mechanical characteristics, which can meet the requirements for most occasions without the need to set a speed feedback circuit outside the Inverter. The setting of this function can be selected between valid and invalid according to the actual situation. The related function is slip compensation control, which is used to compensate for speed deviation caused by load fluctuations, and can add the slip frequency corresponding to the load current. This function is mainly used for positioning control.   16. Energy saving control Fans and water pumps both belong to reduced torque loads, meaning that as the speed decreases, the load torque decreases proportionally to the square of the speed. Inverters with energy-saving control functions are designed with a dedicated V/f mode, which can improve the efficiency of motors and Inverters. This mode can automatically reduce the output voltage of the Inverter based on the load current, thereby achieving energy-saving goals. It can be set to be effective or ineffective according to specific circumstances. It should be noted that the nine and ten parameters are very advanced, but some users are unable to enable these two parameters during equipment renovation, that is, the Inverter trips frequently after activation, and everything is normal after shutdown. The reason for this is that: (1) there is a significant difference in the parameters between the original motor and the motor required for the Inverter. (2) Insufficient understanding of parameter setting function, such as energy-saving control function can only be used in V/f control mode and cannot be used in vector control mode. (3) The vector control method has been enabled, but manual setting and automatic reading of motor parameters have not been carried out, or the reading method is incorrect.        Unleash the power of industrial automation with Rockss Automation, the leading provider of a diverse range of variable frequency drives, drivers, motors, and more.

There are various types of Siemens PLCs, such as Siemens PLC S7-200 series and Siemens PLC S7-300 series, which are widely used in various industrial automation fields. During use, users need to process analog signals to implement various logic. The following article introduces the Siemens PLC analog processing method, in order to better use Siemens PLC for users.   Siemens PLC Analog Processing Method     1. Standard signal In the era of electric sensors, central control becomes possible, which requires long-distance transmission of detection signals. However, the direct transmission of complex physical signals will greatly reduce the applicability of the instrument. Moreover, most sensors belong to the weak signal type, and long-distance transmission is prone to attenuation and interference issues. Therefore, secondary transmitters and standard electrical transmission signals emerged. The function of a secondary transmitter is to amplify the sensor signal into an electrical signal that meets industrial transmission standards, such as 0-5V, 0-10V, or 4-20mA (among which 4-20mA is more commonly used). By shifting the zero point and adjusting the gain of the amplifier circuit, the transmitter can accurately correspond the standard signal to the detected range of physical quantities, such as 0-100 ℃ or -10-100 ℃. This is a mathematical transformation of physical quantities using hardware circuits. The instruments in the central control room drive these electrical signals to mechanical voltmeter and ammeter to display the measured physical quantities. For different range ranges, simply replace the dial behind the pointer. Replacing the dial will not affect the fundamental nature of the instrument, which brings unlimited benefits to the standardization, universality, and large-scale production of the instrument. If you are looking for a reliable and efficient variable PLC, come to Rockss Automation to take a look and perhaps find a satisfactory product. We have different brands of PLC,such as Siemens PLC, Allen-Bradly PLC, Schneider PLC,etc.         2. Digital instrument  In the digital era, pointer display meters have become more intuitive and accurate digital display methods. In digital instruments, this display method actually uses a purely mathematical method to invert the standard signal, becoming a common way of expressing physical quantities. This transformation relies on software for mathematical operations. These operations may be linear or nonlinear equations, and today's computers are easy to handle these operations.     3. Mathematical problems in signal transformation The transformation of signals requires the following process: physical quantity - sensor signal - standard electrical signal - A/D conversion - numerical display. For simplicity, we are discussing linear signal transformations here. Simultaneously skip the signal transformation process of the sensor. Assuming the physical quantity is A, the range is A0-Am, and the real-time physical quantity is X; The standard electrical signal is B0-Bm, and the real-time electrical signal is Y; The A/D conversion value is C0-Cm, and the real-time value is Z. Thus, B0 corresponds to A0, Bm corresponds to Am, Y corresponds to X, and Y=f (X). Due to its linear relationship, the equation is obtained as Y=(Bm B0) * (X - A0)/(Am A0)+B0. Due to its linear relationship, the mathematical equation Z=f (X) after A/D conversion can be expressed as Z=(Cm C0) * (X-A0)/(Am A0)+C0. So it is easy to conclude that the mathematical equation for inverse transformation is X=(Am A0) * (Z-C0)/(Cm C0)+A0. The X calculated in the equation can be directly expressed as the detected physical quantity on the display.     4. Calculation method of inverse transformation in PLC Taking Siemens PLC S7-200 and 4-20mA as examples, after A/D conversion, we obtained values of 6400-32000, C0=6400, and Cm=32000. So, X=(Am A0) * (Z-6400)/(32000-6400)+A0. For example, a certain temperature sensor and transmitter detect -10-60 ℃, expressed as X=70 * (Z-6400)/25600-10 using the above equation. After calculating the mathematical operation instructions of the PLC, the Siemens HMI can read from the result register and directly display it as engineering quantity. Using the same principle, we can input engineering quantities on the HMI and then convert them into standardized values used by the control system through software. In Siemens PLC S7-200, the calculation results of (Z-6400)/25600 are very important values. This is a real number from 0 to 1.0 (100%) that can be directly sent to the detection value input of the PID instruction (not the instruction wizard). The PID instruction outputs real numbers from 0 to 1.0, which can be converted into 6400 to 32000 through the inverse calculation of the previous formula, and sent to the D/A port for 4-20mA output.      Our team of experienced professionals is dedicated to delivering personalized services that exceed our customers' expectations.

ABB is a famous brand in Europe and even the world. High and low voltage inverters, high and low voltage electrical appliances, transformers, motors, power generation equipment, etc. are its mature products, and are widely used in power plants, chemicals, paper making, metallurgy and other industries. It should be said that ABB's products have received unanimous recognition from a large number of users in China. The ABB Inverters occupy an important position in the Inverter market due to their stable performance, rich optional expansion functions, flexible programming environment, good torque characteristics, and various series that can be used in different occasions. The performance of ABB Inverters in the Chinese market is evident to everyone. ABB Inverters, with their strong brand effect and high social awareness, are at the forefront of the Chinese Inverter market. So, in the maintenance of ABB Inverters, customers often provide some fault codes, but engineers cannot understand how to handle and inspect these fault codes when they occur. Therefore, to determine a machine fault, we need to first understand the meaning of the fault code reported by ABB Inverter ACS800, so that we can quickly and accurately determine its fault, solve the problem in a timely manner, and avoid more losses. The following are basically all possible causes of overcurrent, which should be analyzed based on the actual process, equipment, and environmental conditions on site. 1. Sudden load change or stall. Method: Check the load, motor current, and mechanical parts of the system.   2. Close the output contactor. Method: If an output contactor is used, the modulation of the Inverter should be stopped first, and then the contactor should be disconnected. Note: There is no such restriction in SCALAR mode   ABB ACS800-04P-0320-3+P901 ACS800 Invert     3. Motor connection error. (Star angle connection) Method: Check the motor voltage and connection method on the motor nameplate and compare them with 99 sets of parameters.   4. The slope time is too short, so that the overcurrent controller does not have enough control time. Method: Check the load and increase the ramp time.   5.Speed or torque oscillation of the motor.       Method: [1] Caused by speed setting: Check if the speed setting value oscillates. [2] Caused by torque setting: Check if the torque setting oscillates. [3] Caused by overcompensation of speed response: Check the parameter settings of the speed regulator. (In some cases, Self-tuning may not bring satisfactory results.) [4] Caused by excessive feedback filtering time. [5] Caused by incorrect pulse encoder value: Check the waveform of the pulse encoder and check the number of pulses. [6] Caused by the motor model: Obtain correct motor data from the motor nameplate and compare 99 sets of parameters.   ABB ACS800-04-0210-3+P901 Inverter   6.Output short circuit: Damaged motor cable or motor.       Method: [1] Check the insulation of the motor and motor cables. [2] Disconnect the motor cable from the Inverter and operate the Inverter in scalar mode. If the Inverter does not trip, it indicates that the Inverter is good.   7.

There are many setting parameters of the inverters, and each parameter has a certain range of choices. During use, it is often encountered that the inverter cannot work normally due to improper setting of individual parameters. Therefore, it is necessary to set the relevant parameters correctly.   Allen-Bradley 22P-D045A103 AB400P 1. Control method: That is, speed control, torque control, PID control or other methods. After adopting the control method, it is generally necessary to carry out static or dynamic identification according to the control accuracy.   2. Minimum operating frequency: That is, the minimum speed at which the motor runs. When the motor runs at a low speed, its heat dissipation performance is very poor. If the motor runs at a low speed for a long time, it will cause the motor to burn out. And at low speed, the current in the cable will also increase, which will also cause the cable to heat up.   3. Maximum operating frequency: The maximum frequency of general inverters is 60Hz, and some even reach 400 Hz. The high frequency will make the motor run at high speed. For ordinary motors, the bearings cannot run at super-rated speed for a long time. Whether the rotor of the motor can withstand such a centrifugal force. CT Emerson SP1405 Inverter 4. Carrier frequency: The higher the carrier frequency is set, the greater the high-order harmonic component, which is closely related to the length of the cable, the heating of the motor, the heating of the cable, and the heating of the inverter.   5. Motor parameters: The inverter sets the power, current, voltage, speed, and maximum frequency of the motor in the parameters, and these parameters can be directly obtained from the motor nameplate. RELIANCE ELECTRIC UAZ3455UAZ3475 Inverter   6. Frequency hopping: At a certain frequency point, resonance may occur, especially when the whole device is relatively high; when controlling the compressor, the surge point of the compressor should be avoided.   7. Acceleration and deceleration time The acceleration time is the time required for the output frequency to rise from 0 to the maximum frequency, and the deceleration time is the time required for the output frequency to drop from the maximum frequency to 0. Usually, the acceleration and deceleration time is determined by the rise and fall of the frequency setting signal. When the motor is accelerating, the rate of increase of the frequency setting must be limited to prevent overcurrent, and when the motor is decelerating, the rate of decrease must be limited to prevent overvoltage. Acceleration time setting requirements: limit the acceleration current below the over-current capacity of the inverter, so as not to cause the inverter to trip due to overcurrent stall; the main points of deceleration time setting are: to prevent the smoothing circuit trip the inverter. The acceleration and deceleration time can be calculated according to the load, but in the debugging, it is often used to set a longer acceleration and deceleration time according to the load and experience, and observe whether there is an over-current or over-voltage alarm by starting and stopping the motor; then gradually increase the acceleration and deceleration setting time. Shorten, based on the principle that no alarm occurs during operation, repeat the operation several times to determine the best acceleration and deceleration time.   Allen-Bradley 25B-D4P0N114 Inverter   8. Torque boost Also called torque compensation, it is a method of increasing the low frequency range f/V to compensate for the torque reduction at low speed caused by the motor stator winding resistance. When it is set to auto, the voltage during acceleration can be automatically increased to compensate the starting torque, so that the motor can accelerate smoothly. If manual compensation is used, according to the load characteristics, especially the starting characteristics of the load, a better curve can be obtained through experiments. For variable torque loads, if the selection is improper, the output voltage at low speed will be too high, which will waste electric energy.   YASKAWA CIPR-GA70B4060ABBA-AAAAAA Inverter        Our team of experienced professionals is dedicated to delivering personalized services that exceed our customers' expectations.
