Chapter 6 - Parameter Description [I/O]
6-36
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.
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.

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.

Does not check the analog input
signal.
half of x1
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.
