Description
The sum of the reference sources is used as speed reference
1.
The subtraction ([22.11 Ext1 speed
ref2]) of the reference sources is used as speed reference 1.
The multiplication of the reference sources is used as speed
reference 1.
The smaller of the reference sources is used as speed
reference 1.
The greater of the reference sources is used as speed
reference 1.
Determines how constant speeds are selected, and whether
the rotation direction signal is considered or not when
applying a constant speed.
Information
1 = Packed: 7 constant speeds are selectable using the three sources
defined by parameters 22.22,
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters 22.22,
In case of conflict, the constant speed with the smaller number takes
priority.

When bit 0 of parameter
(Separate), selects a source that activates constant speed 1.
When bit 0 of parameter
(Packed), this parameter and parameters
