Chapter 6 FBD Block Diagram Programming 193
(2)AR mode2
Function description:
AR will vary from 0 to current level at a preset rate when it is enabled. Based
on the state of Sel1 and Sel2, Current level will change to other preset level at
the preset rate. When AR is disabled, current output vary to 0 immediately.
The rate designed by user:
. The table below describes detail information of each parameter:
Sel1
Sel2
＝
＝
0: target level = Level 0;
S1＝0,S2＝1: target level = Level 1;
S1＝1,S2＝0: target level = Level 2;
＝
＝
1: target level = Level 3;
MaxL
MaxL is used as target level if the selected level is bigger than
MaxL.
Ta
The result of MaxL divided by Ta is the change rate from
current level to target level.
The output coil turns ON when A is 0.
Timing diagram for AR
Rate = MaxL/Ta; T1=Level0*Ta/MaxlL; T2=（Level1-Level0）*Ta/MaxL;
T3=（Level1-Level2）*Ta/MaxL; T4=（Level3-Level2）*Ta/MaxL;
AR current value: 0~32767
