Function number 800 is used to display the Error List. The following steps
explain how to display errors via the LCDU display:
❏ Press the Up or Down Arrow keys to select the desired function number,
800. The display shows a description of the function on the top line, and the
action that may be performed on the bottom line.
Error Reporting
(F800)
VIEW ERROR LIST
(press ENT) F800
❏ Press the ENT key. If there are no errors in the list, then a no error message
will be displayed.
No ERRORS yet
(press ESC)
If there are errors in the list, then the first error in the list will be displayed.
❏ Press the Down Arrow key to view the errors in the list. For example:
MATH UNDERFLOW
05:35:12 *B00702
The top line describes the error, and the bottom line displays the elapsed time
since the error occurred along with the PAC block that was being executed.
The elapsed time is a measurement of how long the drive has been powered
up since the error occurred. There are two formats in which the elapsed time
will be displayed; HH:MM:SS (for hours, minutes, and seconds) if the error
occurred within 24 hours, and DDD-HH:MM (for days, hours, and minutes)
if the error occurred more than 24 hours ago.
The “*” character before the B on the bottom line marks a fixed entry in the
error list. Only that one error list entry will display the “*” character. There
is no start to the error list since it may be overwritten at any time. The “*”
character is used to show when one complete loop of the error list has been
viewed.
