MV upper limit
MV lower limit
MV change rate limit
• The "MV upper limit" and "MV lower limit" parameters set the upper and lower
limits of the manipulated variable. When the manipulated variable calculated by
the E5EK-DRT controller is outside of the upper-and lower-limit range, the upper
Function
limit 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 vari-
able 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".
• MV upper limit
The setting ranges during standard control and heating and cooling control are
different. Also, the manipulated variable at the cooling side during heating and
Comment
cooling control is expressed as a negative value.
