Bias And Gain Of Frequency Setting Voltage (Current) (Pr. 125, Pr. 126, Pr. 241, C2 (Pr. 902) To C7 (Pr. 905)) - Mitsubishi Electric FR-E720-0.1K(SC) Instruction Manual

4.17.3 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,
0 to 10V or 4 to 20mADC).
Set Pr. 267 and voltage/current input switch to switch between 0 to 5VDC, 0 to 10VDC, 0 to 20mADC using terminal 4.

This parameter can be set when Pr. 160 User group read selection = "0". (Refer to page 188)
∗2
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).
∗3
This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.
