Gain:
Use parameter 04-12 to adjust the gain for AO. Adjust the gain so that the analog output (10V) matches
100% of the selected analog output signal (04-11 for AO).
Bias:
Use parameter 04-13 to adjust the bias for AO. Adjust the bias so that the analog output (0V) matches 0%
of the selected analog output signal (04-11 for AO).

F-Gain Function:
The F- Gain function offers the ability to use a single frequency reference set by a master potentiometer to more than
one inverter. The master frequency can be scaled by three individual potentiometers for each inverter as show in the
diagram below.
To enable set parameter 04-16=1 and set parameter 00-05 =2 (external Analog input AI1). Analog input 2 (AI2) can
now be used for external scaling (potentiometer).
