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.
