Industrial robotics have the power to drastically change and improve lives and business processes – increasing warehouse material handling throughput, and revolutionizing manufacturing with collaborative robots. Celera Motion’s Everest Series servo drives are ultra-miniature, high performance, compact and versatile – delivering precise, stable, repeatable, and safe motion control for co-bot applications.
The Challenge
Industrial robotics have the power to drastically change and improve lives and business processes – increasing warehouse material handling throughput, and revolutionizing manufacturing with collaborative robots. When designing industrial robotics, electronics need to be tightly integrated within the actuation of the robot, and heat dissipation must be controlled. Multi-axis robots require smooth, precise, and safe motion, which can generate demand on the controller to have deterministic coordination and low latency of communication.
The Solution
The Everest Series are a new generation of ultra-miniature, high performance, compact and versatile servo drives. Cutting-edge transistor technology enables the highest power density without sacrificing efficiency, limiting the amount of energy lost through heat dissipation, while minimizing total size. The Everest Series servo drives deliver up to 60A peak current, with an input voltage up to 72V. Fully optimized motion control and communication layers result in ultra-fast control loops with EtherCAT and CANopen, as well as minimal latency, ideal in distributed control systems. This results in the most precise, stable, repeatable, and safe, motion control available for co-bot applications.
The Benefit
The extremely compact and miniature servo drive design easily integrates in enclosed spaces. Pluggable design facilitates customization of interface boards to meet customer size specifications. Small and versatile robots in warehouse manufacturing require the drive to be fully integrated, close to the motors, in the axis or joint, reducing wiring and the removal of a centralized electrical cabinet, freeing floor space. 4kW power delivered at optimal efficiency allows high power motors to be controlled with minimal heat dissipation.
Ultra-fast control loops enable precise trajectory tracking and rapid dynamic response – key performance differentiators in robotic applications. These control loops combined with an optimized communication layer allows CANopen/EtherCATwith very high update rates and low latency, reducing the potential lag between the master controller and the drives of the network. Lag is critical in both trajectory planning for tasks, and safety prevention for system correction if needed.
