The Lexium 05 range of drives have an internal braking resistor included in the drive. The internal braking resistor is connected as standard when the drive is delivered from the factory with a link between the terminals PA/+ and PBi. To use an external braking resistor, you need to: Remove the link between PA/+ and PBi and then you can connect an external braking resistor between the PA/+ and PBe terminals. You can see the example of these connections below.
