Frequency/torque setting by analog
input (terminal 1, 2, 4)
4.21.5 Bias and gain of frequency setting voltage (current)
(Pr. 125, Pr. 126, Pr. 241, C2(Pr. 902) to C7(Pr. 905), C12(Pr. 917) to C15(Pr. 918))
Frequency setting bias/gain parameter
Speed limit bias/gain parameter
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 0 to 20mADC).
Set Pr. 73, Pr. 267 and voltage/current input switch to switch between 0 to 5VDC, 0 to 10VDC and 4 to 20mADC.
