4.Technical Principles and Innovative Values​

Innovation Point 1:The Okuma BL2-D75-A uses advanced vector control technology.This technology allows the drive to independently control the torque and speed of the servo motor with high precision.Compared to traditional scalar control methods,vector control reduces torque ripple by up to 30%,resulting in smoother motor operation and improved positioning accuracy.In applications such as precision machining,this reduction in torque ripple is crucial for producing high-quality finished products.​

Innovation Point 2:The drive is equipped with real-time monitoring and self-tuning functions.It can continuously monitor the operating conditions of the motor,such as temperature,current,and speed.Based on this data,the drive can automatically adjust its control parameters to maintain optimal performance.For example,if the motor temperature rises during continuous operation,the drive can reduce the output power slightly to prevent overheating,while still ensuring that the machine can continue to operate without significant loss of productivity.This self-tuning feature reduces the need for manual intervention and maintenance,increasing the overall uptime of the industrial equipment.​

Innovation Point 3:Okuma has integrated advanced communication interfaces into the BL2-D75-A.The Ethernet and RS-485 interfaces enable seamless communication with higher-level control systems,such as programmable logic controllers(PLCs)and industrial PCs.This allows for easy integration into complex industrial automation networks,where the drive can receive commands and send back real-time status information.In a smart factory environment,this communication capability is essential for achieving efficient production line management and remote monitoring.​

5.Application Cases and Industry Value​

Case 1:A medical device manufacturing company was facing challenges in the production of high-precision surgical instruments.The grinding and polishing processes required extremely accurate control of the machine tools.By using the Okuma BL2-D75-A servo drive,they were able to achieve a surface finish accuracy of within 0.001 mm.This high level of precision not only met the strict quality standards of the medical device industry but also reduced the scrap rate by 30%.The company was able to increase its production capacity by 25%due to the improved efficiency and quality of the manufacturing process.​

Case 2:In a food and beverage packaging plant,the BL2-D75-A was used to control the filling and capping machines.The drive’s fast response time and precise control over the motors ensured that the filling volumes were consistent within a tolerance of±0.5 ml.This high level of accuracy reduced product waste by 15%and improved the overall packaging quality.Additionally,the drive’s reliability reduced the downtime of the packaging line by 20%,allowing the plant to meet its production targets more consistently.​
