As to the analog output of AO1 and AO2, you can adjust
the output gain to change the measuring range or
calibrate the meter.
 Note:
Changing the settings of F7.30 and F7.31 will influence the
analog output.
F7.32 Maximum output
frequency of DO
Range:0~50.0kHz
【10.0KHz】
F7.32 defines the permissible maximum frequency of
DO, refer to F7.28.
F7.33 Preset counting value
Range: F7.34~9999【0】
F7.34 Specified counting value
Range: 0~F7.33【0】
F7.33 and F7.34 are complements for No. 12 and 13
functions in Table-5-11.
It defines after Xi receives the number of pulse F7.33,
the relay or Yi (bi-direction open-collector output
terminal) will give a signal.
For example: as shown in Fig. 5-50, when the eighth
pulse signal is received by terminal Xi, Y1 outputs an
indicating signal. At this time F7.33=8.
When Xi receives the number of pulse F7.34, Yi will give
a signal which will last until F7.33 arrives.
As shown in Fig. 5-50, when Xi receives the 5th pulse,
Y2 outputs an indication signal. It lasts until X1 receives
the 8th pulse. In this case, F7.34=5, F7.33=8. F7.34 is
invalid if it is bigger than F7.33.

Fig. 5-51 terminal’s positive and negative logic
Where,
A: Thousand’s place B: Hundred’s place
C: Ten’s place D: Unit’s place
F7.35 defines the terminal’s positive and negative logic
Positive logic: Terminal Xi is enabled if it is connected to
the common terminal;
Negative logic: Terminal Xi is disabled if it is connected
to the common terminal;
If the bit is set at 0, it means positive logic; if set at 1, it
means negative logic.
For example:
If X1~X8 are required to be positive logic, terminals
FWD and REV are required to be negative logic,
terminal Y1 is positive logic and terminal Y2 is negative
logic, then the settings:
Logic status of X4~X1 is 0000, and the hex value is 0;
Logic status of X8~X5 is 0000, and the hex value is 0,;
Logic status of Y2, Y1, REV and FWD is 1011, and the
hex value is B, so F7.35 should be set at “0B00”. Refer
to Table 5-13.
