FANUC MOTN-208 (“WARN Config Not Reached (L:…)”): The Auto Singularity Avoidance function ignores the taught wrist configuration (flip/nonflip) to avoid a detected singularity.

Description
The Auto Singularity Avoidance function ignores the taught wrist configuration (flip/nonflip) to avoid a detected singularity. As a result, the taught configuration might not be reached. This warning message is posted under single-step-forward mode when the actual configuration is different from the taught one.
Remedy
Make the taught configuration reachable by touching up the point at the stop position when the warning message is posted under single-step-forward mode.
