Description
The smaller of the reference sources is used as frequency
reference 1.
The greater of the reference sources is used as frequency
reference 1.
Determines how constant frequencies are selected, and
whether the rotation direction signal is considered or not
when applying a constant frequency.
Information
1 = Packed: 7 constant frequencies are selectable using the three
sources defined by parameters 28.22,
0 = Separate: Constant frequencies 1, 2 and 3 are separately activated
by the sources defined by parameters 28.22,
respectively. In case of conflict, the constant frequency with the smaller
number takes priority.
Constant frequency configuration word.
When bit 0 of parameter
0 (Separate), selects a source that activates constant
frequency 1.
When bit 0 of parameter
1 (Packed), this parameter and parameters
frequency sel2 and
three sources whose states activate constant frequencies as
follows:
