Alarm Tracing
Alarm tracing records data in the SERVOPACK from before and after an alarm occurs. This
data helps you to isolate the cause of the alarm.
You can display the data recorded in the SERVOPACK as a trace waveform on the SigmaWin+.
9.5.1
Data for Which Alarm Tracing Is Performed
Two types of data are recorded for alarm tracing: numeric data and I/O signal ON/OFF data.
9.5.2
Applicable Tools
The following table lists the tools that you can use to perform alarm tracing and the applicable
tool functions.
• Alarms that occur when the power supply is turned ON are not recorded.
• Alarms that occur during the recording of alarm trace data are not recorded.
• Alarms that occur while utility functions are being executed are not recorded.
