4.4 Setting the input type
4-11
Settings Required
for Basic Control
For information on direct and reverse operation, refer to "4.7 Setting output param-
eters" (P.4-14).
•Alarm
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 output" (P.4-23).
• Input Shift
The sign of the input shift value will be inverted. Therefore, set input shift value 1
and input shift value 2 to values that invert the sign of the display value.
For information on input shift, refer to "5.1 Input adjustment functions" (P.5-2).
•SP Ramp
The rise and fall of the ramp will be inverted. Therefore, set the rising direction of
the display value for the "SP ramp fall value" and the falling direction of the display
value for the "SP ramp rise value."
For information on the SP ramp, refer to "5.2 Control functions" (P.5-8).
• PID Set Automatic Selection
If "PID set automatic selection data" is set to PV, set the "PID set automatic
selection range upper limit" so that the set values decrease for the PID set
numbers in ascending order as shown in the following figure.
If "PID set automatic selection data" is set to DV, the DV used when performing
auto-select will be inverted.
For information on PID set automatic selection, refer to "5.2 Control functions" (P.5-
8).
