Cause : Braking Resistor Fault comes when the resistance of the braking resistor is too low ot the proper braking resistor option has not been installed.

1. A regenerative converter, regenerative unit, or braking unit is being used and the ⊕1 or ⊕3 terminal is connected to ⊖ terminal.
2. Select a braking resistor option that it fits the drive braking transistor specification.
3. Set L8-55 to 0 to disable the braking transistor protection selection.
