Error Indication

When an error occurs, an error code appears on the front panel of the laser processing machine controller.
Errors are categorized into alarm and warning depending on their details.
This chapter describes the details and measures of errors.

Alarm

Errors that occur when highly emergent safety function is activated or there is any abnormality in laser processing machine
are output as alarm.
When an alarm occurs, the laser supply (laser pumping) is turned OFF, and the laser radiation is stopped if during lasing.
„ Release method of alarm
1. Remove a cause of alarm and confirm the safety. (Any alarms due to hardware's problem cannot be released.)
