When control characteristics are already known, the PID parameters can be set
directly to adjust control.
PID parameters are set in the “proportional band” (P), “integrated time” (I) and
“derivative time” (D) parameters (level 1 mode).
For details on the setting ranges of these parameters, see chapter 5 Level 1 Mode
(page 5-18).
About PID Param-
eters
The E5EK-T differs from fixed-value type controllers in that the SP changes au-
tomatically. So, the timing of AT execution is the most important factor in con-
trol.
To obtain PID parameters for a specific SP, make a fixed-value program as follows
and execute AT.

ing

CHAPTER 3 BASIC OPERATION
E5EK
3--26
In this example, let’s execute 40%AT.
(1) Select the menu display, and select “
: level 1 mode” using the
or
keys. For details on selecting the menu display, see page
1-10.
(2) Press the
key to enter the level 1 mode. The top parameter in
the setup mode “
: AT execute/cancel” is displayed. In this
example, the parameter setting is “
: AT cancel”.
(3) Press the
key to specify [
].
(4) The AT LED flashes, and AT execution starts. When the AT LED
goes out (end of AT execution), the parameter automatically re-
turns to “
: AT cancel”.
Setting Example
