5.3 Output adjustment functions
■ MV limit
• Upper and lower limits can be applied to the output of the calculated
MV.
• When using ON/OFF control, the MV will be the MV upper limit
when output is ON and the MV lower limit when output is OFF.
• The MV limit function does not operate when floating control is
selected on a position proportional type.
• The following MVs take precedence over the MV limit function.
Manual MV default
MV at stop
MV at PV error
• The "MV upper limit" and "MV lower limit" can also be set in each
PID set.
• In the case of heating/cooling control, overall upper and lower limits
are set for heating and cooling. (Separate limit settings are not
possible.)
