6) Interrupt input signal logical NOT
Turn the "Interrupt signal logic reverse" relay ON or OFF (see the following table) to specify the logic of
the interrupt input signal. However, if the user interrupt input command is set for the pulse output
destination device, the interrupt input signal logical NOT function cannot be used.

The interruption positioning operation is described below assuming that Y000 is specified as the pulse output
destination device by
For this reason, if Y001, Y002, or Y003 is specified, it is necessary to change the output number of each
related flag.
