Braking Resistors
During deceleration, or with an over hauling load, the motor acts as a generator. Energy flows back from the motor into the dc link capacitors within the drive, causing their voltage to rise. If this voltage exceeds a maximum value, the drive will trip to protect the capacitors and internal power devices. The amount of energy that can be absorbed by the capacitors can vary between different applications causing the drive to trip on overvolts. To increase the drive’s dynamic braking capability, high power resistor(s), connected across the dc link, allow the dissipation of this excess energy for short term stopping or braking.
