Q: How has the acceptance of industrial networks, especially deterministic networks such as EtherCAT, improved motor/drive solutions?
A: Industrial networks have allowed machine builders to choose products that fit their application and still make them work together as a complete, singular solution. The ability to put the drives on the machine closer to the motor has improved machine design. The network allows real-time monitoring that can be used in the controllers programming by the engineer to create custom functions in the controller that help keep the machine running at peak performance. These custom functions could be things like collision detection, heat sealing and changing drive tuning based of product change, as well as many others. As these networks use higher speeds, we can gain more accurate control of the motion control. With the higher bandwidth of the network, tuning can be shared by the drive and the controller to bring new capabilities to the industry. This allows for higher accuracies creating a better product while also producing less waste at the same time.
Q: How does the motion-control network help with configuration, control and even maintenance of motor/drive systems to improve sustainability?
A: Utilizing an industrial network brings benefits to many aspects of the machine. Use of a network can simplify wiring of the machine and save tremendous amounts of time during manufacturing. Configuration, programming and monitoring can now be done from a single software package and a single backup file for the entire machine. Startup and programming can be done from a single connection to the machine eliminating time to walk around and connect to different components to configure them. Monitoring can be done to multiple aspects of the machine through the network, and software packages can trace many parameters so that in-depth analysis can be done to check the performance and accuracies of the machine. The network also brings improvement to maintenance and overall equipment efficiency (OEE). Components that have parameters that need to be set, like a servo drive, can have those parameters stored and downloaded right from the machine controller. This eliminates time to get a laptop with the configuration software and downloading the parameters from a configuration backup file. Some drives now have warnings that components, such as fans or capacitors, are having problems and may be close to the end of their lives. This allows for predictive maintenance before the component failure would cause downtime.
Q: What impact have remote monitoring and connectivity had on the maintenance and useful lives of motion-control components?
A: Keeping a machine running at its peak performance and productivity is always the goal. We can use industrial networks to monitor components and watch for problems that are building—heat, high current, fan failure, capacitor life.
Omron is expanding products to be able to monitor components and monitor their health. This allows products close to the end of their life to be replaced during the maintenance shift where the machine is not in production to reduce failures and downtime.
Q: What innovations is Omron developing to improve speed and accuracy in motion applications?
A: We have seen more machines that are needing high speeds while maintain very high accuracies. Maintaining both high speed and accuracies takes a lot of power from the controller’s CPU, as well as firmware that helps the machine performs to its peak ability. Omron has and will continue to create hardware, firmware and software to improve our controller’s performance. CPUs are getting faster and with multicore CPUs we can utilize each core to gain efficiencies for the controller. Separating out processing components and running them each on their own core helps with CPU efficiencies.
