Figure 23 - Selected Speed Reference
Parameter 27 [Speed Ref A Sel] and parameter 28 [Speed Ref B Sel] determine
the source of Reference A and B. Parameter 27 and 28 can be set to the following
values:
Speed Reference Scaling
Parameter 10 [Speed Ref 1] and parameter 12 [Speed Ref 2] are real parameters
with units of per unit, where a value of 1 per unit equals base motor speed. Speed
reference 1 and 2 each have their own scaling blocks. The speed reference value in
parameter 10 [Speed Ref 1] is divided by the scaling value set in parameter 11
[Spd Ref1 Divide]. The speed reference value for parameter 12 [Speed Ref 2] is
multiplied by the scaling parameter 13 [Spd Ref2 Multi].
Setting Description
0 - Zero Speed Zero Speed is selected as the speed reference.
1 - Speed Ref 1 Parameter 10 [Speed Ref 1] is selected as the speed reference
2 - Speed Ref 2 Parameter 11 [Speed Ref 2] is selected as the speed reference
3 - Sum Sref 1+2 The sum of [Speed Ref 1] and [Speed Ref 2] is selected as the speed reference.
Note that there is no “Speed Ref 3” parameter
4 - MOP Level Speed reference from motor operated pot, parameter 1090 [MOP Level Real].
5 - Preset Spd 1 Parameter 14 [Preset Spd 1] is selected as the speed reference
6 - Preset Spd 2 Parameter 15 [Preset Spd 2] is selected as the speed reference
7 - Preset Spd 3 Parameter 16 [Preset Spd 3] is selected as the speed reference
8 - Preset Spd 4 Parameter 17 [Preset Spd 4] is selected as the speed reference
9 - Preset Spd 5 Parameter 18 [Preset Spd 5] is selected as the speed reference
10 - Preset Spd 6 Parameter 19 [Preset Spd 6] is selected as the speed reference
11 - Preset Spd 7 Parameter 20 [Preset Spd 7] is selected as the speed reference
12 - DPI Port 1 The speed reference comes from local drive mounted HIM
13 - DPI Port 2 The speed reference comes from the external DPI communication module
14 - DPI Port 3 The speed reference comes from the auxiliary external DPI communication module
16 - DPI Port 5 The speed reference comes from the internal DPI communication module
