(1) This area is used to set the manipulated value in the "MAN" mode.
(2) Write a value to the MAN output setting buffer memory after confirming that the
corresponding bit of the manual mode shift completion flag (buffer memory
address: 1E
) has turned to 1 (ON).
H
If this setting is made when the manual mode shift completion flag is off, the
system will rewrite it to the manipulated value calculated by PID operation.
(1) This setting is made to set the variation of the set value per minute to a set value
(SV) change. This will suppress a derivative kick (sudden change in the
manipulated value).

Set value (SV) 2

(2) Make this setting as a percentage of the input range setting (buffer memory
address: 20
, 40
H
The setting range is 0 to 1000 (0 to 100.0%/min).
(1) This setting is made to perform auto tuning centering on a shifted point (AT point).
Make this setting when shifting the point of the set value (SV) for auto tuning.
Make this setting if an excess of the process value over the set value (SV) will be
inconvenient for auto tuning.
(2) Set the range which has minimal PID operation fluctuations and will not affect the
control results.
Otherwise, exact PID constants may not be provided depending on the object to
be controlled.
