Output Adjustment
Functions Output Limits
Output limits can be configured to limit the output using the Upper- and
Lower-Limits to the calculated MV.
The following MV takes priority over the MV limits.
• Manual MV
• MV at stop
• MV at PV error
Figure 4.164
Note: 1. When the manual MV limit is enabled, the manual MV will be
restricted by the MV limit.
Note: 2. For heating/cooling control, Upper- and Lower-Limits are config-
ured of overall heating/cooling control. (They cannot be config-
ured separately for heating/cooling.)
Figure 4.165
MV at Stop
You can configure the amount the MV is output during the controller STOP
mode using the MV at Stop parameter. 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 configuring the MV at Stop parameter also
configure the MV at Stop and Error Addition parameter (Advanced Setting
function group) to ON. The default is 0.0, so an MV will not be output for
either standard or heating/cooling control.
