Dynamic Braking Resistor Overload

What does RH mean?

The protection for the dynamic braking resistor, based on setting of L8-01, has been activated. This fault is typically caused by an overhauling load, an extended dynamic braking duty cycle that exceeds the resistor's capacity, or a defective dynamic braking resistor, leading to overheating.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Replace the dynamic braking resistor if it is defective, improperly sized for the application, or shows signs of overheating damage.
