(2) Control Computation Function
(a) Target setting point and the number of PID parameter
groups
Respectively, twenty sets of target setpoints and
alarm setpoints.Sixteen sets of PID parameters can
be set. For dual-loop control and cascade control, respectively,
sixteen sets can be set for loop-1 (primary
side) and loop-2 (secondary side).
(b) Selecting the PID parameter group
The following PID parameter groups can be selected.
• Target setpoint number (SPNO) (The PID number
can be set arbitrarily.)
• Measured input zone PID
• Target setpoint zone PID
• Reached target setpoint zone PID
(c) Auto-tuning
• Tuning results can be selected from two options,
Normal or Stable.
• Tuning output limit can be set. (It cannot be used in
heating/cooling control.)
(d) “Super” function: Overshoot-suppressing function
(e) “Super 2” function: Hunting-suppressing function
(f) STOP preset output function
(g) Input ERROR preset output function
(h) MANUAL preset output function
