MV change rate limit

The "MV upper limit" and "MV lower limit" parameters set the upper and lower lim-
its of the manipulated variable. When the manipulated variable calculated by the
E5CK controller is outside of the upper-and lower-limit range, the upper limit or
Function
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.
The "MV change rate limit" function is disabled when this parameter is set to "0.0".
MV upper limit
The setting ranges during standard control and heating and cooling control are dif-
ferent. Also, the manipulated variable at the cooling side during heating and cooling
Comment
control is expressed as a negative value.
