Power-on Time/After Reset -- 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. Use this field with “Run Time” to estimate the
utilization ratio of the machine. The value for this field is cleared to zero
when the “Run Time” field is cleared to zero; it cannot be changed
independently.
Cycle Time -- indicates the elapsed execution time for each individual part
program. Cycle time begins counting when the cycle-start button is
pressed and ends when an M02 reset or M30 is encountered. To reset this
field to zero, use one of three methods:
press the cycle-start button to initiate program execution
turn off the control power
follow these steps:
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.
Workpieces Cut/After Reset -- indicates the total number of part
programs executed to completion by the control since the last time “Run
Time” was reset. 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).
The value for this field is cleared to zero when the “Run Time” field is
cleared to zero; it cannot be changed independently.
Lot Size -- is the number of times you need to execute this particular part
program. To enter a new number:
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 numeric value at the prompt for this field.
4. Press
[TRANSMIT]
to change the current value.
