Dynamic Braking

Motor Control Accessories

The table below lists the performance of 200V-class inverter models with the optional external braking units. In some cases, the resistor selection specifies multiple resistors in a parallel, series, or combination parallel/series configuration. The example diagram shows a parallel configuration. Please refer to the braking resistor documentation for detailed wiring diagrams.
