Parameter
Frequency setting by analog input (terminal 2, 4)
FR-D700 SC EC
6 - 153
6.15.3
Bias and gain of frequency setting voltage (current)
[Pr. 125, Pr. 126, Pr. 241, C2 (Pr. 902) to C7 (Pr. 905)]
You can set the magnitude (slope) of the output frequency as desired in relation to the frequency
setting signal (0 to 5V DC, 0 to 10V DC or 0/4 to 20mA DC).
These parameters can be used to configure the inverter precisely for set point signals that either
exceed or do not quite reach 5V or 10V or 20mA. These settings can also be used to configure
inverse control (i.e. high output frequency at minimum set point signal, minimum output
frequency at maximum set point signal).
The above parameters can be set when Pr. 160 = 0.
The parameter number in parentheses is the one for use with the operation panel (PA02)
for the FR-E500 series or parameter unit (FR-PU04/FR-PU07).
The above parameter allow its setting to be changed during operation in any operation mode
even if "0" (initial value) is set in Pr. 77 "Parameter write selection".
