I/O-06 ~ I/O-10: Analog Current Input (I) Signal
Adjustment
This is used to adjust the analog current input signal
when the terminal ‘I’ references the frequency. This
function is applied when DRV-04 is set to ‘I’, or
V1+I’. Reference frequency versus Analog current
input curve can be made by four parameters of I/O-07
~ I/O-10. 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-87
[I user unit selection].

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 (or
target value) when there is minimum current (I/O-07)
input 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 (or
target value) when there is the maximum current
input (I/O-09) on the ‘I’ terminal.
