Chapter 6 - Parameter Description [I/O]
6.4 Input/Output Group [I/O]
This is the minimum voltage of the V1 input at which
inverter outputs minimum frequency.

I/O-01 ~ I/O-05: Analog Voltage Input (V1) Signal
Adjustment
This is used to adjust the analog voltage input signal
when the frequency is referenced by the control
terminal ‘V1’. This function is applied when DRV-04
is set to ‘V1’, ‘V1S’, or ‘V1+I’. Reference frequency
versus Analog voltage input curve can be made by
four parameters of I/O-02 ~ I/O-04. User-selected
Unit appears in [**]. To change the unit, more than
one in APP-02 [PID operation selection] and APP-80
[Ext. PID operation selection] is set to “Yes” and
then select the desired unit Percent, Bar, mBar, kPa,
and Pa among in I/O-86 [V1 user unit selection].

This is the inverter output maximum frequency (or
target value) when there is the maximum voltage
(I/O-03) on the V1 terminal.

I/O-02
This is the filtering time constant for V1 signal input.
Increase this value if the V1 signal is affected by
noise causing unstable operation of the inverter.
Increasing this value makes response time slower.
