This parameter is used to select a preset speed reference as follows:
0 Preset selection by terminal input
1 Preset 1 selected if Pr 1.49 = 3, AN1 selected if Pr 1.49 = 1, AN2 selected if Pr 1.49 = 2
2 Preset 2 selected
3 Preset 3 selected
4 Preset 4 selected
5 Preset 5 selected
6 Preset 6 selected
7 Preset 7 selected
8 Preset 8 selected
When this parameter is set to 0 the preset selected depends on the state of bit parameters Pr 1.45, Pr 1.46 and Pr 1.47. These bits are for control by
digital inputs such that presets can be selected by external control. The preset selected depends on the binary code generated by these bits as
follows:
Pr 1.50 indicates the preset selected at all times.
If the reference selected by Pr 1.14 (or Pr 21.03) is 1 or 2 (current or voltage) a preset will be selected instead of the current or voltage selection if the
preset selected is any other than 1. This give the user the flexibility to be able to select between voltage and 3 presets, or current and three presets,
with only two digital inputs.
This parameter is the reference used when keypad reference is selected.
The range depends on the setting of Pr 1.10:
Pr 1.10 Range
0:Pr 1.07 to 1500 Hz or Pr 21.02 to 1500 Hz
1:±1500 Hz
