ABB frequency converters are widely used, and various malfunctions are inevitable during use. There are generally two methods for handling ABB frequency converter faults (similar to other frequency converter faults): fault code analysis method and main circuit analysis method. 1. Fault code analysis method If the ABB frequency converter has a fault, there are corresponding fault codes on the operation panel. Generally, when dealing with frequency converter faults, it is necessary to find its fault code on the operation panel and conduct a deeper analysis based on the fault code. Based on my personal experience in frequency converter maintenance and some common fault codes, I will briefly discuss some common fault handling methods. 1.1 Fault code: BRAKEFLT Reason for malfunction: Brake failure, brake opening timeout or brake not opening properly. Solution: Open...

power input Equipped with three-phase AC power input terminals, used to connect the power input to the frequency converter. According to different power standards and load requirements, different power wiring methods can be selected, such as star wiring or delta wiring. motor output Used to connect the motor to the frequency converter and achieve speed control of the motor. The motor output terminals are usually composed of three-phase output terminals, corresponding to the three-phase inputs of the motor. By adjusting the output frequency and voltage through a frequency converter, the motor speed can be precisely controlled. SPEED FEEDBACK Used to receive feedback signals of motor speed to achieve closed-loop control. By comparing the speed feedback signal with the set target speed, the frequency converter can automatically adjust the output frequency and voltage t...

The sensor adopts 0-10V three wire voltage signal, of which the terminals are 10, 5 and 4. It sends the signal to the frequency converter to control the speed of the motor and realize stable uncoiling and paying off. The uncoiler has negative effect and the winder has positive effect. The frequency converter model is fr-a740-2.2k Equipment parameters Parameter number name set up Remarks PR79 Operation mode 2 External control mode PR1 Upper limit frequency 50   PR2 Lower limit frequency 0   PR3 Reference frequency 50 Set the frequency of the rated torque of the motor PR7 Acceleration time 1   PR8 Deceleration time 1   PR9 Electronic overcurrent protection 0   PR0 Increase starting torque 6% It can be adjusted without adjustment.

Thanks to flexible automation platforms, biopharmaceutical OEMs can now use one-time use technology (SUT) to achieve intelligent and miniaturized production, and then rapidly expand production scale. In the past decade, modular factories and single use technology (SUT) have rapidly developed and been widely applied in the biopharmaceutical industry. Data shows that over 85% of biopharmaceutical manufacturers rely on SUT for trial commercial scale production, followed by rapid commercial production. Leading biopharmaceutical OEM manufacturers are fully aware of the challenges and opportunities in today's market. Undoubtedly, the market's demand for equipment agility is increasing. These devices not only need to meet the needs of new modular factories and support small batch production, but also need to be easily expandable to meet the requirements of commercial produc...

Firstly, determine whether the PLC is a source input or a drain input, and then select the type it supports Number of encoders. The source type is current outflow, and the drain type is current inflow. Due to the different designs and uses of PLCs by various brand manufacturers, the definitions of source and drain types are relatively different (for example, Mitsubishi's definition is exactly opposite to Siemens' definition). Mitsubishi's source input and drain input are both relative to the PLC common terminal (COM terminal or M terminal), where current flowing out is the source type and current flowing in is the drain type. Siemens' source input and drain input are both relative to PLC input terminals, with current flowing out being the source type and current flowing in being the drain type.             The output OUT terminal ...

1、 Material Selection Guide 1. Plastic materials Plastic is one of the most commonly used 3D printing materials due to its wide selection and relatively low cost. The most common plastic materials include polyvinyl ketone (PEEK), ABS (acrylonitrile butadiene styrene copolymer), PLA (polylactic acid), and nylon. Every type of plastic has its advantages and disadvantages, so choosing the material that suits your project needs is very important. -PEEK: PEEK is a high-performance polymer with excellent heat resistance, corrosion resistance, and chemical stability. It is usually used to manufacture parts that require high temperature and chemical corrosion resistance. -ABS: ABS is a common plastic material with good strength, impact resistance, and heat resistance. It is suitable for manufacturing large and durable parts. -PLA: PLA is a biodegradable p...
