Displaying alarms

If the machine develops a fault in operation, an alarm is generated and machining is possibly
interrupted.
The error text that is displayed together with the alarm number gives you more detailed
information on the error cause.
You have the possibility of saving all of the relevant diagnostic data to a ZIP file, which you can
subsequently send to the hotline for analysis.
Dangers for persons and machines
Carefully check the system, based on the description of the active alarm(s). Resolve the cause
of the alarms. Then acknowledge the alarms in the specified way.
Failure to observe this warning will place your machine, workpiece, saved settings and possibly
even your own safety at risk.
