This parameter is used to select a preset speed reference as follows:
0 Preset selection by terminal input
1 Preset 1 selected (If 1.49 = 3)
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 1.45 , 1.46 and 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:
Parameter 1.50 indicates the preset selected at all times
In analog reference 1 and analog 2 modes, a preset speed will be selected instead of analog reference 1 or analog
reference 2 if the preset speed selected is any other than preset speed 1 even if the preset reference 1.42 is not
selected. This is because of the easy set-up modes that give the user the flexibility to select between analog
reference 1 and 3 preset speeds, or analog reference 2 and 3 preset speed with only 2 digital inputs.
This parameter is the reference used when keypad reference is selected.
The range depends on the setting of 1.10 :
The drives normal frequency resolution is 0.1Hz.
Selecting these two parameters as a reference automatically selects high resolution control (unless a frequency or current
limit is hit or slip compensation is enabled). The frequency in this case will have a resolution of 0.001Hz or 1 mHz. Parameter
1.18 defines the reference (either positive or negative) with a resolution of 0.1Hz. Parameter 1.19 defines the fine part of the
reference (always positive). The final reference is given by 1.18 + 1.19 . Therefore 1.19 increases positive references away
from zero, and decreases negative references towards zero.
