Selection
No.
Not selected / uint32
When bit 0 of parameter 28.21 Constant frequency function
is 0 (Separate), selects a source that activates constant
frequency 3.
When bit 0 of parameter 28.21 Constant frequency function
is 1 (Packed), this parameter and parameters 28.22
Constant frequency sel1 and 28.23 Constant frequency
sel2 select three sources that are used to activate constant
frequencies.
See table at parameter 28.22 Constant frequency sel1.
For the selections, see parameter 28.22 Constant
frequency sel1.
