NOTE: After setting the limit value, the value of valve stroke (POS) on the display may bigger than 100% or smaller than 0%. Do
not set the gap between MIN and MAX smaller than required in the application, since it may result in instability. Decreasing the
gap between MIN and MAX may require the AUTO DB value to be increased.
