Settings 0.00~100.00%
When Pr.03-29=1, ACI setting is 0-10V and the unit is in voltage (V).
When Pr.03-29≠1, ACI setting is 0-20mA or 4-20mA and the unit is in current (mA).
When setting analog input ACI to frequency command, it 100% corresponds to Fmax (Pr.01-00
Max. operation frequency).
The 3 parameters (Pr03-57, Pr03-59 and Pr03-61) must meet the following argument: P03-57 <
P03-59 < P03-61. The 3 proportional points (Pr03-58, Pr03-60 and Pr03-62) doesn’t have any
limit. Between two points is a linear calculation.
The output % will become 0% when the ACI input value is lower than low point setting.
For example:
P03-57 = 2mA; P03-58 = 10%. The output will become 0% when AVI input is lower than 2mA. If
the ACI input is swing between 2mA and 2.1mA, drive’s output frequency will beats between 0%
and 10%.
