When alarm "41" is issued at X1 axis and then alarm "255" is
issued at Y1 axis
Since this information is transmitted from the drive to the CNC through a low-speed mes-
sage line, the alarm indication at CNC has a few-minute delay from the alarm-issued time.
However, the alarm time counter shows a precise time.
„ Drive Digital operator display
Alarm for an axis selected by the Digital operator is displayed as follows:
Example: A.51 --- Alarm "51" (a "Drive code" in the Alarm list) is issued at a drive selected.
• Alarm code for a drive is displayed in decimal number on the CNC screen, while it is displayed in
hexadecimal number on the Digital operator.
• For drive alarm codes, refer to Appendix B.1 "List of Servo unit alarms" and Appendix B.2 "List
of Inverter alarms".
