PID proportional band
0.1% 100%
0.1 to 1000%
If the proportional band is narrow (parameter
setting is small), the manipulated variable
varies greatly with a slight change of the
measured value. Hence, as the proportional
band narrows, the response sensitivity (gain)
improves but the stability deteriorates, e.g.
hunting occurs.
Gain K = 1/proportional band
9999 No proportional control
