Power-on Time/Overall -- indicates the total accumulated time that the
control has been ON. This value is saved in backup memory each time the
control is powered off, so it is restored at its previous value each time the
control is turned ON. To clear this field to zero:
1. Press the
{ED PRT INFO}
softkey, provided that you have
supervisor-level access.
2. Press the up or down cursor keys to move to this field or the next
field without changing the current value.
3. Enter a Y at the prompt for this field.
4. Press
[TRANSMIT]
to clear the current value.
Workpieces Cut/Overall -- indicates the total number of part programs
executed to completion by the control. Use this field to determine the need
for periodic checkups or as a statement of warranty. This counter is
incremented by one each time the control encounters an M02, M30, or an
M99 in a main part program (M99 in a subprogram does not increment this
counter, though M02 or M30 does). To clear this field to zero:
1. Press the
{ED PRT INFO}
softkey, provided that you have
supervisor-level access.
2. Press the up or down cursor keys to move to this field or the next
field without changing the current value.
3. Enter a Y at the prompt for this field.
4. Press
[TRANSMIT]
to clear the current value.
Run Time -- indicates the total accumulated time that part programs were
executing with the control in automatic mode. Use this field with
“Power-on Time/After Reset” to estimate the utilization ratio of the
machine. To clear this field to zero:
1. Press the
{ED PRT INFO}
softkey if you have either operator-level or
supervisor-level access.
2. Press the up or down cursor keys to move to this field or the next
field without changing the current value.
3. Enter a Y at the prompt for this field.
4. Press
[TRANSMIT]
to clear the current value.
