By setting thresholds for total number of movements and total distance travelled, you can notify an
external device, by means of a message level error or output signal that each threshold has been
exceeded. (Alert function)
[How to set a threshold under the alert function]
Method 1:
Change the value of Axis-specific parameter No. 221, “Threshold for total number of movements” or No.
222, “Threshold for total distance travelled,” whichever is applicable, on the parameter edit screen.
Method 2:
Perform one of the following operations in the desired “New value” cell and enter a new threshold value:
• Double-click the cell.
• Press the “Ctrl” and “Space” keys together.
• Press a number key.
When the new threshold value has been entered, click the button to transfer the new threshold to the
controller.
When the transfer to the controller is complete, the confirmation message, “Write Flash ROM?” appears.
Fig. 11.25 Confirmation
Click to select the items (parameters, etc.) you want to write to the flash ROM.
Yes (Y) Write the memory data to the flash ROM.
No (N) Do not write the memory data to the flash ROM.
When a reset is performed (by turning off the power and then turning it back on, or
resetting the software), the memory data will be destroyed and data will be loaded from
the flash ROM. (The controller will use the transferred memory data until the reset
takes effect.)
(Note) If a reset is performed (by turning off the power and then turning it back on, or resetting the
software) without writing the parameters to the flash ROM first, the threshold under the alert
function will not be changed and the value set before the change will be restored.
(Note) The flash ROM can be written only for so many times (approx. 100,000 times).
Unless all data are written, select “Write the selected data areas” before writing to the flash ROM.
