NO. OF WORK MACHINING
—
(CURRENT VALUE)
[Function]
The No. of work machining current value and maximum value are notified by the controller to the
PLC.
[Operation]
If data is set in the No. of work machining (WRK COUNT M) and work machining maximum value
(WRK LIMIT) of the [Process parameters], the current value or maximum value of the No. of work
machining is output.

R241

R941
(Note 1) If data is not set in "WRK COUNT M" and "WRK LIMIT" on the [Process Parameter]
screen, data will not be output to the file register.
(Note 2) If the No. of work machining matches or exceeds the work maximum value, the "No. of
work machining over" signal (X66E) turns ON.
<Counting of No. of work machining using user PLC>
(1) Set "0" in "WRK COUNT M" on the [Process Parameter] screen. With this setting, the controller
side will not count up.
(2) Add "1" to R240, 241 with the user PLC.
(3) The controller will display R240, 241 as the No. of work machining on the [COORDINATE]
screen. Even in this case, if the No. of work machining matches or exceeds the work maximum
value, the "No. of work machining over" signal (X66E) will turn ON.
