Displaying faults and alarms
Every fault and alarm is entered in the fault/alarm buffer along with the time at which it
occurred. This time stamp can take two forms:
● Number of days, hours, minutes, and seconds since the AOP was first switched on
(format DDDD: HH:MM:SS) (no "AOP→ Drive" time synchronization)
● System time (format YY:MM:DD HH:MM:SS = Year:Month:Day Hour:Minute:Second), in
cases where a time-of-day master is present in the system (if "AOP → Drive" time
synchronization is active, for example)
You can call up an overview screen that displays the current status of faults and/or alarms
for every drive object in the system by choosing MENU – Fault/alarm memory.
A shortcut menu offering the "Back" and "Ack." options appears when you press F4
("Tools+"). (You can use F4 to exit the shortcut menu.) The function required can be
selected using F2 and F3 and executed by pressing F5 ("OK").
The "Ack." function sends an acknowledgement signal to each drive object.
The red FAULT LED goes out once all the faults have been acknowledged.
Figure 9-23 Fault screen
You can use F5 (Ack.) to acknowledge a stored fault.
Figure 9-24 Alarm screen
Alarms that are no longer active are removed from the alarm memory with F5 (Clear).
The screen can be updated via a submenu with F4 (More+).
