DEAD BAND
Mechanical Steps at least 0.2mA
What is DEAD BAND ?
It’s an area/band where no action occurs due to the actuator input.
If the user inputs 12mA (50%), the actuator is supposed to stop exactly at 50% poaition. The actuator repeats from open
to close in order to stop at 50% position at this point.
This is what we call hunting, and if the hunting effect repeatedly occurs the motor can be damage. Therefor a dead band
is set to have some area in order to prevent this from happening.
It’s set to have 0.05mA per gradation. If it is at 1PH when shipped from the factory, it is set to have a 0.2mA dead band. If
it is at 3PH, on the other hand, it is set to have a 0.3mA dead band.
ex) If it is set to have a 0.2mA dead band, the actuator is positioned between 11.8mA to 12.2mA.
In case the actuator stops at the position of 12.1mA, the second least movement area will be at
12.3mA. At this position no action occurs even when there is the input signal.
