PID1 target value selection
• Select PID1 target value.
• In the case of setting target value with one input,
set 00: None to [AH-42]/[AH-46] and 01: Add to
[AH-50] to disable the input destination 2/3.
■ When operator [AH-50] is 01 to 04
When operator [AH-50] uses 05 or 06
• When 05 or 06 is selected in operator [AH-50],
(Target value 1) - (Feedback value 1)
(Target value 2) - (Feedback value 2)
(Target value 3) - (Feedback value 3)
these 3 deviations are compared and PID
calculation is performed by using the deviation of
minimum (05)/maximum (06).
• Calculation result of operator [AH-50] will be
restricted in a range of -100.00 to 100.00 (%).
• When 01 to 04 is selected in operator [AH-50],
calculation is targeted to target value 1 and target
value 2.
• Select 00: Disable for target value and feedback
value not in use.
