(3) Precautions
• There are two sampling buffers for saving the data current when the alarm occurs. Thus, the
data can be saved even if an alarm occurs while diagnosing an occurring alarm.
The data cannot be saved if the alarm occurs when two storage areas are already used.
Press the EXIT menu in the NC ALARM GUIDANCE screen, and release the buffer area to
enable use.
• After an alarm occurs, the sample data is automatically erased when the time set in the base
specifications parameter (#21030) has elapsed.
The sampling data will also be erased if the EXIT menu in the NC ALARM GUIDANCE screen is
pressed.
