The pulse input has a central point. The frequency at the central point is half of the maximum pulse input
frequency P09.11. When the input pulse frequency is lower than the central point frequency, the
corresponding values are positive.
2: Central point mode 2
The pulse input has a central point. The frequency at the central point is half of the maximum pulse input
frequency P09.11. When the input pulse frequency is higher than the central point frequency, the
corresponding values are positive.

When the terminal X6 is used as the high-speed pulse input terminal, this function code defines the
filtering time of the input pulse. The longer the filtering time is, the slower the reference pulse frequency
change rate will be.
Fig. 6-33 Terminal positive/negative logic setting
This function code defines the positive/negative logic of the input terminal.
Positive logic: enabled when the Xi terminal is connected to the corresponding common end,
disabled when the terminal is disconnected;
Negative logic: disabled when the Xi terminal is connected to the corresponding common end,
enabled when the terminal is disconnected;
Input terminal valid status setting 00
3FH (00)P09.15
Input pulse filtering time 0.00~10.00s (0.05s)P09.14
