Bias And Gain Of Frequency Setting Voltage (Current) (Pr. 125, Pr. 126, Pr. 241, C2(Pr. 902) To C7(Pr. 905)) - Mitsubishi Electric FR-F720P-0.75K to 110K Instruction Manual

4.17.5 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. 73 and Pr. 267 to switch between 0 to 5VDC, 0 to 10VDC and 4 to 20mADC. (Refer to page 185)

*1 This parameter can be set when Pr. 160 User group read selection = "0". (Refer to page 201.)
*2 The parameter number in parentheses is the one for use with the 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.
*4 Performing IPM parameter initialization changes the settings. (Refer to page 80)
