[Cause]
Machine locking is applied to other action groups than machine locking and action groups with a common brake number. The first parameter in parentheses indicates the brake number that failed to release the brake. The second parameter indicates that the group number that cannot release the brake has been set.
[Countermeasure]
1. Also apply machine lock to action groups with a common brake number.
2. Change the brake connection to avoid using the same brake number between different action groups.
