8.7.1 Physical Dimensions of External DC Reactor
The motor and load's regenerative energy is almost completely consumed on the braking
resistor when braking.

Different systems select different braking voltages. The 380 VAC system usually selects
700 V braking voltage.
Pb refers to the braking power.
8.7.2 Selection of Power of Braking Resistor
In theory, the power of the braking resistor is consistent with the braking power. But in
consideration that the de-rating is 70%, you can calculate the power of the braking resistor
DFFRUGLQJWRWKHIRUPXOD[3U 3E['
Pr refers to the power of resistor.
D refers to the braking frequency (percentage of the regenerative process to the whole
working process)
