5.4.5 Braking Components
Resistance of braking resistors
During braking, almost all the regenerative energy of the motor is consumed by the
braking resistor. The resistance of the braking resistor is calculated by the following
formula: U x U/R = Pb.
U indicates the braking voltage used to stabilize the system braking. The value of U
varies with systems. The default braking voltage of the MD520 is 760 V, which can be
adjusted through F9‑08.
Pb indicates the braking power.
Power of braking resistors
In theory, the power of braking resistor is the same as the braking power. However, in
consideration of the derating coefficient K, the power of the braking resistor is
calculated by the following formula: K x Pr = Pb x D.
