E-030 positive characteristics / negative characteristic
E-031 analog input bias
E-032 analog input gain
E-030 is used to select positive/ negative characteristics when set frequency
method by external analog input
(
analog voltage input0~5V/10V, external analog
current input 4~20mA, panel potentiometer
)
.
0——positive characteristic
；
1—— negative characteristic
When set frequency by external analog signal input
(
0~5V/10V
，
4~20mA
)
or
panel potentiometer, you can set output frequency by adjusting values of E-031 and
E-032.
Initial settings of inverter: input: 0~5V, corresponding output frequency: 0 ~

，
X means input voltage
，
Y means output frequency
，
at this time, bias
E-031 = 0.0
，
gain E-032 = 1.00.
