P1.2.1
121
Local reference “local reference”
Defines which frequency reference source is used when control place is Local set
in P2.1 Control Place, or forced through DIN, or selected from the keypad local
remote button.
0=”AI1” - Analog Input 1.
Signal scaling in “G1.4.2: Input Signals\Analog Input 1”
1=”AI2” - Analog Input 2.
Signal scaling in “G1.4.3: 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 thus when both are at 100 % final reference will be 50 Hz.
3=”AI1-AI2”
Analog Input 1 - Analog Input 2.
4=”AI2-AI1”
Analog Input 2 - 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 input “G: Input Signals\Digital Inputs” (increase
and decrease). Behaviour adjusted in “G: Ref Handling\Motor Potentiometer”.
11=”AI1, AI2 min”
The minimum of Analog Input 1 and Analog Input 2 is used as reference.
12=”AI1, AI2 max”
The maximum from 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
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 sued to elect between “I/O Reference” and “I/O Reference
2” if selection is different than 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 used e.g. for speed synchronization where two motor needs to run at
same speed but not necessarily same angle.
17=”PID Output”
Reference is read from the output of the PID controller see group P1.17 for PID
controller settings
P1.2.2
117
Remote 1 reference selection “remote 1 ref”
Defines which frequency reference source is used when control place is Remote
1 set in P2.1 Control Place, or forced through DIN, or selected from the keypad local
remote button.
0=”AI1” - Analog Input 1.
Signal scaling in “G1.4.2: Input Signals\Analog Input 1”
1=”AI2” - Analog Input 2.
Signal scaling in “G1.4.3: 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 thus when both are at 100 % final reference will be 50 Hz.
