MEMO
How to reset the generated warning and output warning signal
There are output of warning occurrence (C753 *, C754 * (* is the axis number)) and dedicated output
signal (M * PTEXC (* is the robot number)) as a notification method of each part replacement time.
When both are set by the notification method, it is possible to turn off the warning occurrence and turn off
the signal output by the error reset operation.
If you wish to invalidate "warning occurrence" and make only the output of the dedicated output signal
valid with the notification method, even if you press the reset button on the front of the controller, the output
signal will not turn OFF. In this case, if you press the [ERROR RESET] key of the teaching pendant or input
the error reset signal (ERRRESET), the signal output turns OFF.

If this is checked, the Maintenance Forecast function is enabled.
* If the checkmark is removed, the collection of Maintenance Forecast
information stops, and the correct maintenance times cannot be
calculated.
Five levels can be specified to collect the information on maintenance.
* As the information collection level gets higher, the accuracy of the
maintenance improves, but it affects the tact time more.
Specify the interval of maintenance time notification.
When the grease replenishment, belt replacement, and other maintenance times
have been reached, they can be notified by generating a warning or outputting a
dedicated signal. As for the battery replacement time, one of warnings, C7500,
C7510, and C7520, is generated, regardless of whether or not [Warning] under
[How to inform] is checked.
The warning generated varies depending on each situation.
If this item is checked, the maintenance time is notified as a warning.
The warning numbers are listed as follows:
Grease : C753* (* is the axis No.)
Belt : C754* (* is the axis No.)
If this item is checked, signal numbers can be entered. If this item is
checked and a signal number is entered correctly, the maintenance
time is notified using the output of the designated signal.
Enter an estimated robot operation hours per day.
Specify the number of days remaining until estimated maintenance
time for use as a reference to notify the maintenance time.
