To provide frequency reference by analog input of control circuit terminal FR
or FC, the relationship between analog input and frequency reference can be
set.

( ) indicates the value when current
reference input is selected.
(a) Analog frequency reference gain (n060)
The frequency reference provided when analog input is 10V (20mA) can
be set in units of 1%. (Max. output frequency n011=100%)
*
Factory setting : 100%
(b) Analog frequency reference bias (n061)
The frequency reference provided when analog input is 0V (4mA or
0mA) can be set in units of 1%. (Max. output frequency n011=100%)
*
Factory setting : 0%
Typical Setting
• To operate the inverter with frequency reference of
0% to 100% at 0 to 5V input
