FCB 58 Supply and regenerative mode
If you activate this FCB, the default regenerative function of the device will be activated. The DC link is precharged and the line contactor is closed. When the DC link reaches nominal voltage, a ready signal is sent to the connected axes, and the output stage is enabled.
