4-16 Output Adjustment Functions
4-16-1 Output Limits
• Output limits can be set to control the output using the upper and lower
limits to the calculated MV.
• The following MV takes priority over the MV limits.
Manual MV (See note.)
MV at stop
MV at PV error
Note When the manual MV limit is enabled, the manual MV will be re-
stricted by the MV limit.
• For heating/cooling control, upper and lower limits are set of overall heat-
ing/cooling control. (They cannot be set separately for heating/cooling.)
4-16-2 MV at Stop
• The MV when control is stopped can be set.
For heating/cooling control, the MV at stop will apply to the cooling side if
the MV is negative and to the heating side if the MV is positive.
When setting the MV when control is stopped, set the MV at Stop and
Error Addition parameter (advanced function setting level) to ON.
The default is 0.0, so an MV will not be output for either standard or heat-
ing/cooling control.
Note The order of priority is as follows: Manual MV > MV at stop > MV at PV error.
