• The MV change rate limit sets the maximum allowed change in the

MV (or the opening on a position proportional control type) 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 "MV change rate limit (heating)". "MV

change rate limit (cooling)" cannot be used.

• For heating/cooling control, the MV change rate limit can be set

separately for heating and cooling. Use "MV change rate limit (heat)"

for heating and "MV change rate limit (cooling)" for cooling.

• The MV change rate limit cannot be used in the following situations:

• Manual mode

• AT is running

• During ON/OFF control (P=0.00)

• During stop (during "Manipulated variable at stop" output)

• During "MV at PV error" output
