Input Filter
Filter Function
The meaning of the filter values shown below:
Inputs accept signals of the pulse width shown.
Soft Filter
0 msec, 3 msec (default), 7 msec, 10 msec
[Setting]
I0 and I1: Independently set
I2 and I3: Set in combination
I4 to I7: Set in combination
Input reject pulse width: (Soft filter value) – 2 msec
Hard Filter
I0: 4 to 616 µsec (ON pulse)
I0: 6 to 618 µsec (OFF pulse)
I1 to I7: 20 to 625 µsec (ON pulse)

Input reject pulse width: (Hard filter value)/3 µsec
Factory Initial Setting Default value
Effect of Improper Input Connection
Both sinking and sourcing input signals can be connected. If any input
exceeding the rated value is applied, permanent damage may be caused.
