*1 (Input delay time) = (Hard filter time) + (Digital filter time)
For the digital filter time of the input terminals used as high-speed counters, the recommended values are shown in "3-1-2
Digital filter setting."
For the input terminals used as normal digital signal inputs, the digital filter time should be set as long as possible according
to the specifications of the switch/sensor to be connected.
*2 The counting speed of the high-speed counter is determined by which input in the above table is used for the count signal.
