The PID algorithm is implemented as a parallel structure with interaction--free parameter set-
ting. The P, D, and I part have separate control difference inputs (xdP, xdD, xdI), the Z part is
added to the output Y
A
.
PI is switched over to P operation with the control signal P = High. Automatic mode is switched
over to manual mode with the control signal H = Hi.
Manual actuation takes place through the control inputs
Δ
y with a Hi signal (e.g. by pressing
a key on the front). Blocking of the output through the digital inputs
Y
BL
(blocking = High) is
provided. The output of the controller is followed up by a control signal N = High to the input
value applied at YN. (Only in K--controller and S--controller ext.)
Parameter control of the most important parameters kp, Tn, Tv by separate inputs SG1 to SG3
is possible. To do this, the basic parameter value cP, tn, tv set in onPA is multiplied with an ex-
ternal function.
The parameter adaptation is possible in offline mode of the respective controller for the parame-
ters cP, tn, tv, vv and AH. The controlled variable x must be fed to the controller for this. If
(CSi*) YR is switched internally with 0.000 or ncon in the S--controller, the value of the step
command is determined from ty.
Then the adaptation can be run in manual mode (see the following description of the
adaptation
and chapter 3.3.2, page 138).
