Cause : Brake control error comes when break open current is not flow any more. If rating current flows below than set value, cut off the output without break open.
"nbr" fault indicate that the rating current flows below than set value.
When the brake control is used, the output current is lower than the rated current value of the motor set and lasts for over 10s, then the inverter output is turned off and the brake is not opened.
