MV Change Rate Limit
2-PID control must be used.
The ST parameter must be set to OFF.
• The MV Change Rate Limit parameter sets the maximum allowable variation in the MV
per second. If the change in the MV exceeds this setting, the MV will be changed by the
MV change rate limit until the calculated value is reached. If the limit is set to 0.0, this
function will be disabled.
• The MV Change Rate Limit parameter will not operate in the following situations.
• In Manual Mode
• During ST execution (Cannot be set when ST is ON.)
• During AT execution
• During ON/OFF control
• While stopped (MV output during STOP)
• During MV output when error occurs

Position Proportional Dead Band A Position-proportional Model must be used.
• When the difference between the MV and the valve opening is within the value that is set
for the Position Proportional Dead Band, opening or closing the valve will be stopped to
prevent the valve from deteriorating.
