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.
The external ZB8110 braking resistor is available as an accessory to the EL9576 brake chopper terminal or the KL9570 buffer capacitor terminal. It regulates the DC link voltage as soon as more braking power is needed. It has a maximum continuous rating of 100 W. The ZB8110 is connected directly to the EL9576 or KL9570. A mounting plate is included in the scope of supply for each braking resistor.
