[Cause]
The conditions for group action resumption have not been met.
[Countermeasure]
1. End the program and start the operation from the same line. Or, perform a backward operation to the same line to resume running the program.
2. When the action immediately before calling a program with a different group mask is the CNT action, change the action to FINE, or change the same group mask.
3. If the motion immediately before returning to a parent program with a different group mask is CNT motion, change that motion to FINE or make the group masks the same.
