NOTE!
1)
Selection 2 is available only if ASi board is not installed. In this case a different
fieldbus can be used to control the reference.When ASi board is installed this
parameter is automatically set to 0.
2)
In AUTO mode, preset speed 1-8 can be directly activated by ASi outputs or
Sensors signals, independently from P3.3 setting.
If P3.3 = 1 and the reference is restored to motor potentiometer, after a preset
speed, P3.17 defines the initial value for the reference.
3)
When ASi board is installed this parameter is automatically set to 0.
