NOTE
 When voltage/current input signal for terminal 4 was switched using Pr.267 and voltage/current input switch, perform
calibration without fail.
(3) Analog input display unit changing (Pr.241)
 You can change the analog input display unit (%/V/mA) for analog input bias/gain calibration.
 Depending on the terminal input specification set to Pr.73, Pr.267, and voltage/current switch, the display units of C3
(Pr.902), C4 (Pr.903), C6 (Pr.904), C7 (Pr.905) change as shown below.

(1) Change the speed at maximum analog
input (Pr.125, Pr.126)
 Set Pr.125 (Pr.126) when changing speed setting
(gain) of the maximum analog input voltage
(current) only. (C2 (Pr.902) to C7 (Pr.905) setting
need not be changed)
Gain
(2) Analog input bias/gain calibration
Pr.125
(C2 (Pr.902) to C7 (Pr.905))
 The "bias" and "gain" functions are used to adjust
the relationship between the input signal entered
from outside the drive unit to set the rotation
speed, e.g. 0 to 5V, 0 to 10V or 4 to 20mADC, and
the output frequency.
 Set the bias frequency of the terminal 2 input using
C2 (Pr.902).
(It is initially-set to the speed at 0V)
 Set the rotation speed in Pr.125 for the speed
command voltage set with Pr.73 Analog input
selection.
 Set the bias speed of the terminal 4 input using C5
(Pr.904).
(It is initially-set to the speed at 4mA)
 Using Pr.126, set the rotation speed relative to
Gain
20mA of the speed command current (4 to 20mA).
Pr.126
 There are three methods to adjust the speed
setting voltage (current) bias/gain.
(a) Method to adjust any point by application of a
voltage (current) across terminals 2-5 (4-5)
page 175
(b) Method to adjust any point without application
of a voltage (current) across terminals 2-5 (4-5)
page 176
(c) Method to adjust speed only without adjustment
of voltage (current) page 177
