Parameter 04-20 can be used to filter momentary changes in the analog output signal.
Note:
Increasing the filter time results in a slower system response, decreasing the filter time may cause instability of the
analog output signal.

Analog output AO adjustment (04-12, 04-13
and 04-15)
Signal
: Use parameter 04-11 to select the
analog output signal for AO.
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 AC Drive. The master frequency can be scaled by three individual potentiometers for each AC Drive as shown in
the diagram below.
To enable set parameter 04-22=1 and set parameter 00-05 =2 (external Analog input AI1). Analog input 2 (AI2) can
now be used for external scaling (potentiometer).
