Parameter 1.21 defines the speed reference for preset speed 1.
Parameter 1.22 defines the speed reference for preset speed 2.
Parameter 1.23 defines the speed reference for preset speed 3.
Parameter 1.24 defines the speed reference for preset speed 4.
Although most parameters can be controlled from analog inputs this parameter is a special case, as, if selected as a speed reference, the
scan rate will be 250µsec.
The range of this parameter is restricted by parameter [1.06].
These bits are provided for control by logic inputs (e.g. digital inputs) for external reference selection. (See parameter 1.14.)
0 = Reference not selected
1 = Reference selected
These bits are provided for control by logic input (e.g. digital inputs) for external preset reference selection. (See parameter 1.15.)
Indicates the reference currently being selected by parameter 1.14. See parameter 1.14 Reference selector description for further details
1 = Analog reference.
2 = Analog reference.
3 = Preset reference selected.
4 = Keypad reference selected.
5=Pulsereferenceselected.
Indicates the preset speed reference currently being selected by parameter 1.15. See parameter 1.15 Preset reference selector description
for further details.
