Introduction：

It is mainly used in the occasions where the drive system of the inverter needs rapid deceleration, braking, positioning and so on. When the inverter is decelerating, due to the large inertia of the driving system, the motor is in the state of generating electricity, and the mechanical energy is quickly fed back to the DC bus, causing the DC bus voltage to rise rapidly, thus endangering the safety of the inverter, so the feedback energy must be Consume it quickly and keep the DC bus voltage below a certain safe range, otherwise the inverter will be over-voltage protected or faulty. Generally, this braking unit can be used when the inertia is large, or when the brake needs to be decelerated sharply. Such as: centrifuges, elevators, cranes, wire drawing machines...
