Gain
Set the signal gain after the offset adjustment.
First apply that signal to which you want to adjust the internal display
(see offset). Then select under C025 the corresponding analog
input. Adjust the signal gain such that the desired set-value is
obtained. For the adjustment of the feedback input see pages 73
and 75.
Code Parameter Meaning Acceptance

-4- Analog input terminals 1 and 2
Analog input terminals 3 and 4
Analog input terminals 7 and 8 SH + PRG
C026 -1000...+1000 mV
(factory setting) Offset correction ON-LINE
C027 1.000 -2.500...+2.500 Signal gain ON-LINE
3.7 Control mode
Under code C006 you can select V/f characteristic control or I
0
control.
Code Parameter Meaning Acceptance
C006 -0-
-1- V/f characteristic control

[SH
˝+ PRG]
The I 0 control, also referred to a "magnetizing current control"
allows a considerably higher torque compared to the normal V/f
characteristic control, without the motor being overexcited when
the drive is deloaded.
