or lower limit set to these parameters is output, respectively.
The MV change rate limit" parameter sets the maximum permissible change width
per second of the manipulated variable. If a change in the manipulated variable
causes this parameter setting to be exceeded, the calculated value is reached while
changing the value by the per second value set in this parameter.
This function is disabled when the set value is 0.0".
