Coordinated Robotic, Motion, and VFD Control

Optimize OEE with a synchronized, motion-centric approach.

“The traditional approach for optimizing OEE on a production line consists of using a PLC
based model from a single source automation supplier. This approach focuses heavily on maintenance in an attempt to limit downtime.” Writes Scott Carlberg from Yaskawa.

Synchronized Motion Control for OEE
“A
alternate and potentially more successful approach is based on a motion-centric model with a focus on productive outcome. 
The key is to not only focus on keeping the machine running, which directly affects the machine availability variable in OEE, but to address all of the OEE variables with a motion-centric solution that is flexible enough to allow for new production innovations.”  Read more from Yaskawa’s OEE whitepaper.

“The throughput of each individual process can be impacted by the capability of the specific motion control solution chosen. Some of the more sophisticated motion control electronics,” like the SGLF2 Series linear servos, “employ advanced servo algorithms that assist in decreasing settling time of discrete machine movements. Even a small decrease in the settling time of each discrete machine movement in a production cycle can result in a significant reduction in overall production cycle time.”

“Giving the production manager the ability to monitor their production line from anywhere at any time can be a key contributor to another OEE variable – increased uptime. Yaskawa’s Variable Frequency Drives (VFDs),” like the all-in-one U1000 drive, “are designed with life monitors that proactively provide the maintenance team with information that will help avoid downtime. The drive sends out notifications and warnings when consumable components like cooling fans, DC bus capacitors, inrush relays, and IGBTs are nearing the end of their predicted lifespan.”
