Setting the Analog Input/Ouput dead band
The dead band value represents the range over which the actuator
allows the input signal to deviate from the actual actuator position
without making any correction. This setting is made at the factory,
but it is possible to adjust it.
If the dead band is too narrow, the actuator could hunt, moving
back and forth in an attempt to reach the input signal value
without stopping within the dead band.
If the dead band is too wide, positioning operations are less
precise.
The default dead band is 1%.
How to set the dead band
