ZB8103 External braking resistor
During the acceleration phase, a motor needs energy supply, whereas during braking a motor can be used as a generator, feeding energy back into the DC link, which raises the voltage in the DC link. If the voltage exceeds the adjustable threshold value, a braking resistor is activated.
