Situation
As the interrupt switch is not set, the
interrupt function is not activated.
Output polarities are mixed.
This error occurs when the sink output,
source output, push-pull output (negative
logic), or push-pull (positive logic) are
mixed.
The input voltage is set by two points.
A value exceeding the operation
guarantee range (over 500,001) is set.
A value exceeding the settable range
(over 100,001) is set.
Solution
Turn on the mode setting switch no. 1 of
the unit to enable the interrupt function.
This is a warning to check if the wiring is
correct.
If you do not want to announce warnings,
set "Warning annunciation" to "Not
announce" using the tool software or
program.
Set the input voltage on a program by
four points.
Monitor the unit memory
(UM0015E/UM0015F) in which the pulse
output flag is stored, and review the
settings after confirming the detailed
information.
Review the set value.
