The Challenge
The field of industrial robotics has the capacity and power to significantly transform business processes and radically improve people’s lives. This is made possible by enhancing warehouse material handling throughput, thus bringing about the potential for a revolution in manufacturing through a collaboration with robots. When developing industrial robotics, integration of the electronics needs to be compact and often intricate within the actuation of the robot, and good control of heat dissipation is vital. Multi-axis robots need motion that is precise, smooth, and safe, and which can generate demand on the controller to have low latency of communication and deterministic coordination.

The Solution
The Everest Series is the next-generation of ultra-miniature, compact, versatile servo drives that excel in high performance capabilities. State-of-the-art transistor technology allows for the highest power density without compromising efficiency. The Everest Series servo drives deliver up to 60A peak current, with an input voltage up to 72V while limiting the amount of energy lost through heat dissipation and reducing the total size.
Consequently, through optimal motion control and communication layers, ultra-fast control loops with EtherCAT and CANopen are achieved, as well as generating minimal latency, a perfect solution in distributed control systems. For co-bot applications, the result is the most accurate, repeatable, robust, and safe, motion control available.

The Benefit
The extraordinarily compact and miniature servo drive design integrates easily into closed and sealed spaces. Customization of interface boards to meet customer size specifications is facilitated by the pluggable design. Small, versatile robots in warehouse manufacturing necessitate that the drive is completely integrated, close to the motors, in the joint or axis, minimizing the wiring and the elimination of a centralized electrical cabinet, freeing up floor space. 4kW power generated at optimal efficiency enables the control of high power motors with minimal heat dissipation.
Ultra-fast control loops permit accurate trajectory tracking and high-speed dynamic response – critical performance differentiators throughout robotic applications. These control loops combined with an optimized communication layer facilitate CANopen/EtherCAT with extremely high update rates and reduced latency; limiting any potential lag between the drives of the network and the master controller. Monitoring lag is vital in both trajectory planning for tasks, and safety prevention for system correction if necessary
