Chapter 6 - Parameter Description [I/O]
119
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.
This is the minimum current of the ‘I’ input at which
inverter outputs minimum frequency.
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 [%].
This is the maximum current of the ‘I’ input at which
inverter outputs maximum frequency.
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;

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

1
The inverter determines that the frequency
reference is lost when the analog input
signal is less than half of the minimum
value (I/O-02 or I/O-07).
below x1
2
The inverter determines that the frequency
reference is lost when the analog input
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.
