Which of the following alarms is not valid in a R-30iB Robot?

In the context of the R-30iB Robot, the validity of alarms is determined by the specific designations and codes assigned to various fault conditions and system alerts.

The alarm designated as MOTN-017 does not align with the typical classifications of movement (MOTN) alarms that are recognized in the R-30iB system. These alarms are categorized based on their purpose and the specific conditions they are meant to indicate within the robot's operating framework.

MOTN alarms usually cover a range of issues related to movement, but the numbering and specific identifiers must be valid according to the system's architecture. In this case, a lack of documentation or recognition of MOTN-017 within the R-30iB's programming establishes that this particular alarm does not exist as an actionable alert in the system, making it the correct choice for this question.

The other options represent valid alarms that are documented within the system's operation manual or programming guidelines. These alarms correspond to recognized faults or conditions that the robot may encounter during operation, which is why they are included in the options.
