4.15.4 Bias and gain of speed setting voltage (current)
(Pr.125, Pr.126, Pr.241, C2 (Pr.902) to C7 (Pr.905))
You can set the magnitude (slope) of the rotation speed as desired in relation to the speed 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 Extended function display selection = "0". (Refer to page 182)
The parameter number in parentheses is the one for use with parameter unit (FR-PU07).
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.
When a value exceeding 3000 r/min is set, the rotation speed will be limited at 3000 r/min.
Also, when an S-PM geared motor is used, the maximum setting value differs depending on the drive unit capacity. (0.2 to 2.2K: 12000 r/min, 3.7K: 8000 r/
min)
