• The MV change rate limits set the maximum allowed change in the
MV (or the opening on a Position-proportional Control Model) per
second. If a change occurs in the MV that exceeds this limit, the MV
will be changed at the set rate limit until the required change is
attained. When set to 0.0, the function is disabled.
• For standard control, use the MV Change Rate Limit (Heating)
parameter. The MV Change Rate Limit (Cooling) parameter cannot
be used.
• For heating/cooling control, the MV change rate limit can be set
separately for heating and cooling. Use the MV Change Rate Limit
(Heating) parameter for heating and the MV Change Rate Limit
(Cooling) parameter for cooling.
• The MV change rate limits cannot be used in the following situations:
• In Manual Mode
• When AT is being executed
• During ON/OFF control (P=0.00)
• During a reset (i.e., while outputting the value set for the MV at
Reset parameter)
• During an error (i.e., while outputting the value set for the MV at
PV Error parameter)
