• Alarms
The upper-limit alarm and lower-limit alarm will be inverted. Therefore, set an alarm type and alarm
values that invert the upper limit or lower limit of the display value. For example, if an absolute-value
upper limit is set for the alarm type, operation will be as shown in the following figure.
For information on alarms, refer to 4.11 Using Auxiliary Outputs (P. 4-37).
• Input Correction
The sign of the input correction value will be inverted. Therefore, set the Input Correction 1 and Input
Correction 2 parameters to values that invert the sign of the display value. For more information on
input correction, refer to 5.1 Input Adjustment Functions (P. 5-2).
Important
• PID Set Automatic Selection
If the PID Set Automatic Selection Data parameter is set to "PV," set the PID Set Automatic Selection
Range Upper Limit parameter so that the set value decreases for the PID set numbers in ascending
order as shown in the following figure.
If the PID Set Automatic Selection Data parameter is set to "DV," the DV used when performing auto-
select will be inverted.
For more information on the PID Set Automatic Selection parameter, refer to 5.2 Control Functions (P. 5-
8).
