Auto-Tune
Tuning procedure calculates the controller parameters and
can be manual or automatic according to selection on para-
meter 46
tune
.
7.3
Manual Tuning
Manual procedure allows the user greater flexibility to decide
when to update PID algorithm work parameters. The proce-
dure can be activated in two ways.
• Running Tuning by keyboard
:
Press
FNC
key until display 1 shows the writing
tune
with
display 2 showing
oFF
, press , display 2 shows

dGt.i.
At first activation of digital input (commutation on front panel)
T
led switches ON and at second activation switches off.
7.4
Automatic Tuning
Automatic tuning activates whenever the controller is switched
on or when the setpoint is modified to a value over 35%.
To avoid an overshoot, the treshold where the controller calcu-
lates new PID parameters is determined by the setpoint value
minus the “Set Deviation Tune” (see Parameter 47
s.d.tu.
).
To exit Tuning and keep PID values unchanged, just press the
FNC
key until display 1 shows the writing
tune
with the display
showing
