VB5N series inverter
69
For analog output AO, you can adjust the output gain to change the measuring range or calibrate the meter.
0: 4 ~20mA
1: 0 ~10V
Refer to Table 4-7 and 4-6 for function selection of DO output terminal.
DO max pulse output frequency
Range: 0.1~20.0 (max 20K)
This parameter defines the max output frequency of DO terminal.
Middle counter value setting
P4.22, P4.23 is the additional definition of No.12, 13 functions in table 4-6.
Counter value setting: when Xi receives certain quantity pulses, OC or relay will output a indicator signal.
For example: as shown in Fig. 4-28, when the eighth pulse is received by terminal Xi, OC outputs an indicating signal and
P4.22=8.
Middle counter value setting: When Xi receives certain quantity pulses, OC or relay will keep output a signal until the
counter value arrives.
As shown in Fig. 4-28, when Xi receives the 5th pulse, the realy outputs indication signal. It keeps outputting until counter
value 8 arrived. At this time, P4.23=5. The middle counting value will be disabled if it is bigger than preset counting value.

Overload pre-alarm detection level
Overload pre-alarm delay time
If output current is over the current detecting level P4.24 continuously (Actual detecting current level＝P4.24×inverter’s
rated current), Bi-direction open-collector will output valid signal (refer to Fig.4-29 and P4.11 for details).
