AR mode2
I
n mode 2, it supports four different preset levels, but only one of these 4 preset levels can be target level at one
time. The current level will change to target level at a designed rate. There are 12 parameters for proper configuration.
The table below describes each configuration parameter and lists each compatible element for configuring AR mode2.
T
he parameters from ② to ⑦ can be constant or refer to the current value of other function. The rate designed by
user:
Ta
MaxL
Rate =
. The table below describes detail information of each parameter of AR mode2.

OFF: target level = Level 0;

S1＝ON, S2＝OFF: target level = Level 2;

ON: target level = Level 3;
MaxL
The AR current value just can reach the MaxL if the target
level is over it.
Ta
The result of MaxL divided by Ta is the raising/lowering
rate from current level to target level.
Error output coil
The error coil turns ON when Ta is 0.
※
The error output coil can be M,N or NOP, it will do nothing if it was selected as NOP.
A
R current value will vary from one level to another lever according to the ON/OFF state of “Sel 1” and “Sel 2”,
and the raising/lowering rate depends on Ta. When AR is disabled, current value goes to 0 immediately. For detail,
you can see the “Timing diagram” show next page.
