Clearing a warning
The alert output can be cleared in the following two methods:
After 'CH1 Digital value' (Un\G460) is set to be smaller than 'CH1 Alert output upper limit value' (Un\G510) and larger than
'CH1 Alert output lower limit value' (Un\G512)
• Turning on and off 'Alert output clear request' (YE)
• Turning on and off 'Operating condition setting request' (Y9)
The D/A converter module arranges the following status when an alert output is cleared.
• Clearing 'Alert output upper limit flag' (Un\G36) and 'Alert output lower limit flag' (Un\G37)
• Turning off 'Alert output signal' (XE)
• Turning off the ALM LED
• Clearing the alarm code stored in 'Latest alarm code' (Un\G2)

Navigation window  [Parameter]  [Module Information]  Module name  [Module parameter]  "Application
setting"  "Alert output function"
2.
Set values for "Alert output upper limit value" and "Alert output lower limit value".
Set the values to satisfy the following relation.
Alert output upper limit value > Alert output lower limit value
Item
Alert output upper limit value
Alert output lower limit value
Precautions
• When the shift function is used in the normal mode, 'CH1 Digital value' (Un\G460) on which the shift-and-add is performed
is the alert detection target. Set the alert output upper/lower limit values in consideration of the shift-and-add.
Setting range
-32768 to 32767
