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.
CAUTION: Continuous HUNTING will cause damage to the motor, PCU-card or
potentiometer.
E) Deadtime Setting
- DEAD TIME setting is to secure the reliability of the command signal.
- Minimum duration time of the input command signal satisfying DEAD BAND.
- Actuator is operated by recognizing input signals satisfying DEAD TIME as command si
gnals.
- Range of DEAD TIME Setting : 0.2 ~ 7.5 seconds (setting in 16 steps)
① Step 0 : 0.2s (the minimum value)
② Step 1 ~ 4 : 0.25s increase per step (0.25 ~ 1 sec)
③ Step 5 ~ 15 : 0.50s increase per step (2.5 ~ 7.5 sec)
④ Factory setting : “2”
