Test Source
When the channel mode of a safety input is set to
Test pulse from test out
,
select the test output to use in combination with the safety input.
The channel mode for the test output selected here is automatically set to
Pulse Test Output
.
Note
The channel mode of the test output selected here automatically
becomes
Pulse Test Output
.
ON Delay Time and OFF Delay Time
These parameters set the ON delay time and OFF delay time for the safety
input. The setting range is 0 to 128 ms, but it must be a multiple of the NE1A-
series Controller cycle time. Check the displayed NE1A-series Controller
cycle time and determine the set value.
IMPORTANT
• The optimum value for the NE1A-series Controller cycle time is auto-
matically calculated based on the parameter settings and the pro-
grams. Therefore, the ON delay time and OFF delay time must be set
last.
• Set integral multiples of the cycle time for the ON delay time and
OFF delay time. Otherwise, an error will be displayed when the Edit
Device Parameters Window is closed.
• Automatic adjustment of ON and OFF delay times can be used with
Network Configurator version 1.6
@
or higher, as described below.
Automatic Adjustment of ON and OFF Delay Times
If parameters that affect the cycle time are changed after the ON and OFF
delays have been set, it may become impossible to close the Edit Device
Parameters Dialog Box due to an error in the parameter settings. If this
occurs, the ON and OFF delay times can be readjusted based on the cycle
time.
As shown in the illustration below, there is a button on the
Local Input/Test
Output
Tab Page for adjusting the effective ON/OFF delay time based on the
cycle time. Pressing this button sets all values to be automatically adjusted as
a multiple of the cycle time.
