Chapter 6 FBD Block Diagram Programming 180
(2)AR mode2
Function description:
AR will vary form 0 to current level at a preset rate when it’s enabled. Base 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:
Ta
MaxL
Rate = . The table below describes detail information of each parameter:
Sel1
Sel2
S1＝0,S2＝0: target level = Level 0;
S1＝0,S2＝1: target level = Level 1;
S1＝1,S2＝0: target level = Level 2;
S1＝1,S2＝1: target level = Level 3;
MaxL
MaxL is used as target level if the selected level is bigger then
MaxL.
Ta
The result of MaxL divided by Ta is the change rate from
current level to target level.
Output coil The output coil turns ON when A is 0.
