Dynamic Braking
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.
