Calculating the allowed continuous braking resistor and DC bus power
By connecting the DC bus connections of several DKC and BZM drive
controllers the regenerative power and regenerative continuous power
resulting in the common DC bus is evenly distributed to all ECODRIVE03
components with a braking resistor.
The distribution to the components involved is realized takes place with a
high balancing factor.
