Follower reference selection “follower ref sel”
Select where the follower drive receives its speed
reference from.
0 = ”AI1” – Analog Input 1
Signal scaling in “G: Input Signals\Analog Input 1”
1 = ”AI2” – Analog Input 2
Signal scaling in “G: Input Signals\Analog Input 2”
2 = ”AI1+AI2” – Analog Input 1 + Analog Input 2
With alternative reference scaling in Analog Input group, 100 % input values
can be set to correspond 25 Hz. In other words, when both are 100% the final
reference will be 50 Hz.
3 = ”AI1-AI2” Analog Input 1 minus Analog Input 2.
4 = ”AI2-AI1” Analog Input 2 minus Analog Input 1.
5 = ”AI1xAI2” Analog Input 1 x Analog Input 2
6 = ”AI1 Joystick” Analog input 1, –10 Vdc... +10 Vdc
7 = ”AI2 Joystick” Analog input 2, –10 Vdc... +10 Vdc
8 = ”Keypad Ref” Reference from keypad R3.2
9 = ”Fieldbus”Reference is taken from fieldbus. Alternative scaling can be selected in
“G: Fieldbus”
10 = ”Motor Pot” - Motor potentiometer
Reference handled with two digital inputs “G: Input Signals\Digital Inputs” (increase
and decrease). Behaviour adjusted in “G: Ref Handling\Motor Poten.mete”.
11 = ”AI1, AI2 min”
The smaller of Analog Input 1 and Analog Input 2 is used as reference.
12 = ”AI1, AI2 max”
The greater of Analog Input 1 and Analog Input 2 is used as reference.
13 = ”Max Freq” – Maximum frequency
P1.1.2 Max Frequency is used as reference.
14 = ”AI1/AI2 Sel” – AI1/AI2 Selection
The digital input “I/O Ref 1/2” is used to select between
Analog Input 1 and Analog Input 2 reference. “I/O Ref
1/2” is used to elect between “I/O Reference” and “I/O Reference 2” if selection
of this parameter is different from 14 (this one).
15 = ”Encoder 1”
Reference is read from encoder input 1.
16 =”Encoder 2”
Reference is read from encoder input 2. This selection is usable with double
encoder boards. Could be utilized e.g.for speed synchronization.
17 =“Master Reference”
Master reference before ramp generator. When this is selected the follower
drive’s own ramp times are active and used.
18 =“Master Ramp Out” Master reference after ramp generator, before speed
controller. When this is selected the follower drive will use the ramp times
defined by the Master drive.
