If the internal DC bus voltage exceeds a specified value, this braking resistor is activated; the restored energy is converted into heat by the braking resistor. It enables maximum braking torque. External braking resistor When the Lexium BMI servo motor has to be braked frequently, an external braking resistor is required to dissipate the excess braking energy. In this case, the internal braking resistor must be deactivated. Several external braking resistors can be connected in parallel. The Lexium 32i monitors the power dissipated in the braking resistor. The degree of protection of the casing is IP 65 for VW3A7601R pp to VW3A7608R pp braking resistors and IP 20 for VW3A770 p braking resistors. The operating temperature around the unit can be between 0 and + 50C (+ 32 and + 122F). An external braking resistor connection module VW3M9010 is required to use an external braking resistor with a Lexium 32i.
