[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 set-
ting signal (0 to 5 V, 0 to 10 V or 0/4 to 20 mA DC).
These parameters can be used to configure the inverter precisely for set point signals that either ex-
ceed or do not quite reach 5 V or 10 V or 20 mA. These settings can also be used to configure inverse
control (i.e. high output frequency at minimum set point signal, minimum output frequency at max-
imum set point signal).
햲
The above parameters can be set when Pr. 160 "User group read selection" = 0.
햳
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).
햴
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".
