MV Change Rate
Limit
• The MV change rate limit sets the maximum allowable width of change per
second in the MV (or the change per second in the valve opening for a
Position-proportional Model). 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. This function is disabled when the setting is 0.0.
• The MV change rate limit does not function 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 (during MV at Stop output)
• During MV at PV Error output
