(800) PID constant setting
<(810/820) PID constant of
detail setting>
PID constant setting is possible. Direct direction (Dir) and reverse
direction (ruS) are settable individually. Easy adjusting is also
possible. For adjustment, see “■Improved Controllability”.
Although PID constant is automatically adjusted during span
adjustment, direct direction (Dir) and reverse direction (ruS) are
settable individually.
Procedure
LCD display
1
Hold down the set button ( )
for 1sec. or longer to start
parameter change mode.
2
Select (Dir) by UP or DOWN button
( ). Hold down the set button
( ) for 1sec. or longer to start
value change mode.
3
To set proportional gain (P
constant) with (811), hold down the
set button ( ) for 1sec. or
longer. After values start to flash,
change the value within the range
of 0.001 to 9.999. After changing,
hold down the mode button ( ) for
1sec. or longer to set the value.
4
Press the UP or DOWN button
( ). As setting proportional
gain (P constant) in clause 3 above,
set integral time (I constant) within
the range of 0.000 to 9.999 with
(812), and set differential time (D
constant) within the range of 0.000
to 9.999 with (813).
5
Hold down the mode button ( ) for
1sec. or longer to return to
parameter change mode.
6
Press the UP or DOWN button
( ) to select reverse direction
(ruS). Hold down the set button
( ) for 1sec. or longer to start
value change mode.
7
Repeat clause 3 to 5 to set PID
constant as setting direct direction
(Dir).
8
Hold down the mode button ( ) for
1sec. or longer. Hold down again
for 1sec. or longer after interval.
