5 Dynamic Braking

During the deceleration of an AC motor and it’s load, a proportion of the stored kinetic energy is converted by the motor into
electrical energy and returned to the inverter. When a high inertia load is decelerated in a short time, the energy returned to
the inverter may be too great to be absorbed by the drive alone. The effect is to increase the voltage on the drives’ DC Bus to
such a level that a DC Bus overvoltage trip will occur.
To overcome these trips, a braking resistor may be fitted to the drive to dissipate this returned energy. The internal braking
control circuitry constantly monitors the drives’ DC Bus to determine when the braking resistor should be operated.
