PARAMETERS
4.13.4 Bias and gain of speed setting voltage (current)
(Pr. 125, Pr. 126, Pr. 241, C2 (Pr. 902) to C7 (Pr. 905))
[Speed setting bias/gain parameter]
∗1 The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 144)
∗2 The parameter number in parentheses is the one for use with the parameter unit (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 Differs according to capacities. (0.2K to 2.2K/3.7K)
∗5 If a value exceeding 3000r/min is set, the actual rotation speed will be limited at 3000r/min.
You can set the magnitude (slope) of the rotation speed as desired in relation to the speed setting signal (0 to 5VDC, 0
to 10VDC or 4 to 20mADC).
Set Pr. 267 and voltage/current input switch to switch among 0 to 5VDC, 0 to 10VDC, and 0 to 20mADC input using
terminal 4. (Refer to page 130)
