Dead Band (dEAdbANd)
Deadband indicates the size of the allowable deviation that is set near the target position. If the valve
has large packing friction, this value can be adjusted and set accordingly to prevent the limit cycle
caused by the friction. If the deadband is set to 0.5%, its range is ±0.5% of the target.
