It defines the max. pulse frequency from terminal
Y2. Refer to F7.12.
F7.33 Preset counting value Range: F7.34 ～ 9999 【 0 】
F7.34 Specified counting
value
F7.33 and F7.34 are complementary to Function
No.12 and No.13 in Table 5-9.
When the number of pulses defined by F7.33 are
input from Xi, Yi or relay will output an indicating
signal.
Suppose F7.33=8, as Fig. 5-49 shows, when 8
consecutive pulses are input from Xi, Y1 will
output an indicating signal.
When the number of pulses defined by F7.34 are
input from Xi, Yi or relay will output an indicating
signal which will last until the number of pulses
defined by F7.33 are input.
Suppose F7.34=5, 7.33=8, as Fig. 5-49 shows,
when 5 consecutive pulses are input from Xi, Y2
will output an indicating signal and it holds the
signal until the 8th pulse passes. Note that if
F7.34 is bigger than F7.33, then F7.34 is invalid.

Fig. 5-50 Positive or Negative Logic of Terminal
The parameter defines the positive or negative
logic of terminals, where positive logic refers that
the terminal Xi is enabled when it connects with
the common terminal and disabled if
disconnected; negative logic is the opposite of
positive logic.
If the bit is set at "0", it means positive logic, and
"1" for negative logic.
Suppose you require X1~X5 to be positive logic,
FWD and REV negative logic, Y1 positive logic
8 9
and Y2 negative logic, you should set the one's
place at 0, ten's place at 0, hundred's place at
(1011)

set at 0B00.
The conversion from binary code to Hex value is
shown in Table 5-13.
