Synchronized
program operation
If the progress of the operation of one unit is
faster, the program operation can be forcibly
stopped by digital input when switching
between segments.
Program pattern link Available
Program pattern edit
Addition and deleting of program segment
can be available. Copy and deletion of
program pattern can also be available.

(2) Control Computation Function
(a) The number of PID parameter groups
Eight sets of PID parameters can be set. For cascade
control, respectively, eight sets can be set for main
(primary side) and slave (secondary side).
(b) Selecting the PID parameter group
The following PID parameter groups can be selected.
• Segment PID
• Measured input zone PID
• Target setpoint zone PID
• Reached target setpoint zone PID
• Local PID
• Reference deviation
(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) RESET preset output function
(g) Input ERROR preset output function

with 4 to 20 mA output, control output
can be reduced to about 0 mA.
