Intelligent energy recovery

January 2024 Editor's Choice Electrical Power & Protection

The AX8820 only starts feeding power back into the grid just before the overvoltage threshold of the connected devices is reached. Several AX8820 regenerative units can be operated in parallel to adapt the regenerative power optimally to the needs of the machine.

No communication via EtherCAT is required to carry out energy recovery. However, extended parameterisation is possible via EtherCAT – to adapt the voltage levels to the connected devices, for example. With the help of the extended diagnostics via EtherCAT, the current regenerative energy can also be analysed. The online data can be used to record the timing of the machine processes. This means that an investigation can be carried out to see whether the efficiency of the machine can be increased by staggering the machine processes.

Loop signature 22: How cyclical disturbances affect a control loop
Michael Brown Control Engineering Editor's Choice
When tuning noisy loops, we recommend in our courses that one should eliminate the noise by editing it out, so the tuning will be done only on the true process response, free of any noise. The controller is controlling the process, and is not controlling the noise.

Navigating disruption in manufacturing
Editor's Choice IT in Manufacturing
When considering IT in manufacturing, the underlying assumption is twofold: first, a wave of valuable maturing technologies can be harnessed to create new business value, and second, the environment in which these technologies will be applied will be relatively predictable, with change following a manageable, evolutionary path. However, recent disruptions have shattered these assumptions.
