Engineering Motoman Certification Practice Exam

Alarm codes on Motoman controllers are organized so the first digit signals the general category of the issue. Minor alarms are associated with the later, broader set of first-digit groups, covering a range of subsystems without indicating an unrecoverable fault. There’s also a distinct first digit used for Application/User alarms, which are defined by the user. Because minor alarms fall within those later-leading-digit groups and user-defined alarms live in their own group, the pattern that matches those ranges is the correct one. The other first-digit groups correspond to different, more critical or different-category alarms, so they do not describe minor alarms.
