D) Deadband Setting
-
Max. allowable value of actuator position error by input command signal.
-
Min. variation range of the input command signal to start operating the actuator.
-
Range of DEAD BAND setting: 0.3 ~ 7.5% (setting in 16 steps)
①
Step 0
: 0.1% increase per step (0.3% ~ 0.7%)
②
Step 1 ~ 4
: 0.2% increase per step (1.0% ~ 1.8%)
③
Step 5 ~ 15
: 0.5% increase per step (5.0% ~ 7.5%)
④
Factory setting
: “2”
-
In case the DEADBAND is set too narrow, the actuator may run back and forward repea
tedly not finding the target position. This is called as HUNTING.
-
DEADBAND should be properly adjusted in order to prevent HUNTING.
