Functions and
Operations
■ MV change rate limit
• The MV change rate limit is used to set a maximum allowed change
per second in the MV (or in the opening of a valve in the case of a
position proportional controll type). If a change occurs in the MV that
exceeds this setting, the MV is changed by the set limit each second
until the required change is attained. When the limit is set to "0", the
function is disabled.
• For standard control, use "MV change rate limit (heat)". "MV change
rate limit (cool)" cannot be used.
• For heating/cooling control, separate limits can be set for heating
and cooling. "MV change rate limit (heat)" is used for heating and
"MV change rate limit (cool)" is used for cooling.
• The MV change rate limit cannot be used in the following conditions:
• Manual mode
• During AT
• During ON/OFF control (P=0.00)
• When control is stopped (MV output at Stop)
• During MV output at PV error
• If you only wish to limit the rate of increase in the MV, set the "MV
change rate limit mode" to "1".
