Frequency setting by analog input (terminal 1, 2, 4)

4.16.4 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 155)
