A.059 PID min pos err
(PID minimun positive error)
Setting of the maximum negative limit of the regulator error. It is expressed as percentage of the full scale value
It defines the threshold for the digital output signalling.
Digital output signalling:
18 PID err><
PIP error is >A.058 &<=A.059
19 PID err>thr
PID error is >A.058
20 PID err<thr
PID error is <=A.059
21 PID er ><(inh)
PID error>A.058 &<=A.059 (*)
22 PID er >(inh)
PID error is >A.058 (*)
23 PID er <(inh)
PID error is <=A.059 (*)
(*) The control through the digital output, can become active only when the error returns the first time in the
preset interval.
Variable monitoring in the DISPLAY MENU

D.400
PID reference
Reference signal
D.401
PID feedback
Feedback signal
D.402
PID error
Signalling of the error between reference and feedback
D.403
PID integral comp
Actual value of the integral component
D.404
PID output
