Alarm KRC0337

KUKA Robot KRC0337 - <command name> <action>

This is an informational alarm indicating that an OBJH (Object Hold) command has completed execution on the KUKA KRC controller. The OBJH command is used to establish or maintain a grasp on an object during robot motion, and this alarm confirms the command sequence has finished without errors. This is a normal operational message rather than a fault condition.
