Some errors must reset even if the error disappear，is it？
Or the error disappear，it dont need the reset command。
some other brand controls need reset even if the error disappear，
i dont find the case in the rmc150.
The bits on the Error Bits register will be latched when an error occurs. Sending the Clear Faults command will clear all the bits whose underlying error condition no longer exists. Also, sending a motion command to the axis will clear all the bits whose underlying error condition no longer exists. Therefore, clearing the bits with the Clear Faults command is not necessary.
