166 Parameters
22.21 Constant speed
function
Determines how constant speeds are selected, and
whether the rotation direction signal is considered or not
when applying a constant speed.
01b
00b…11b Constant speed configuration word. 1 = 1
22.22 Constant speed sel1 When bit 0 of parameter 22.21 Constant speed function is
0 (Separate), selects a source that activates constant
speed 1.
When bit 0 of parameter 22.21 Constant speed function is
1 (Packed), this parameter and parameters 22.23
Constant speed sel2 and 22.24 Constant speed sel3
select three sources whose states activate constant
speeds as follows:
DI2
Not selected 0 (always off). 0
Selected 1 (always on). 1
DI1 Digital input DI1 (10.02 DI delayed status, bit 0). 2

mode
1 = Packed: 7 constant speeds are selectable using the three sources
defined by parameters 22.22, 22.23 and 22.24.
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters 22.22, 22.23 and 22.24 respectively.
In case of conflict, the constant speed with the smaller number takes
priority.
