I/O-11: Criteria For Analog Input Signal Loss - LG SV-iS5 Instruction Manual

I/O? I filter
06 10 ms
Factory Default:
10 ms
This is the filtering time constant for ' I' signal input. If the
' I' signal is affected by noise causing unstable operation
of the inverter, increase this value. Increasing this value
makes response time slower.
I/O? I curr x1
07 4.00 mA
Factory Default:
4.00 mA
This is the minimum current of the ' I' input at which
inverter outputs minimum frequency.
I/O? I freq y1
08 0.00 Hz
Factory Default:
0.00 Hz
This is the inverter output minimum frequency when
there is minimum current (I/O-07) on the ' I' terminal. In
torque mode, the display is changed to [%].
I/O? I curr x2
09 20.00 mA
Factory Default:
20.00 mA
This is the maximum current of the ' I' input at which
inverter outputs maximum frequency.
I/O? I freq y2
10 60.00 Hz
Factory Default:
60.00 Hz
This is the inverter output maximum frequency when
there is the maximum current (I/O-09) on the ' I' terminal.
In torque mode, the display is changed to [%].
Setting FU2-39 [Control mode select] to Vector_Torque
or Sensorless_T, the setting value is changed to Torque
value as below;
Code Default Setting
I/O-07 4 [mA] 0 ~ 20[mA]
I/O-08 0 [%] 0 ~ 150[%]

I/O-11: Criteria for Analog Input Signal Loss

I/O? Wire broken
11 None
Factory Default:
None
This is to set the criteria for analog input signal loss
when DRV-04 [Frequency Mode] is set to ' V1' , ' I' or
' V1+I' . Following table shows the setting value.
Setting Range
LCD 7-Seg
0
None Does not check the analog input signal.
The inverter determines that the frequency
reference is lost when the analog input
1
half of x1
signal is less than half of the minimum
value (I/O-02 or I/O-07).
The inverter determines that the frequency
reference is lost when the analog input
2
below x1
signal is less than the minimum value (I/O-
02 or I/O-07).
When the analog input signal is lost, inverter displays the
following table.
Setting

Loss of frequency reference from Option Board
LOP PL
(DPRAM time out)
