In the following diagram the solid line shows an example in which threshold 2 is reached, while the broken line shows
an example in which threshold 2 is not reached after the timeout. In both cases, PID parameters are calculated and
autotuning is correctly completed.

Menu PAR Description UM Typo FB BIT Def Min Max Acc Mod
26.2.13 7628 PID 1 fbk tune min PID1U FLOAT 0.0 0.0 0.0 RW VS
Setting of the minimum value for the feedback signal during the autotuning procedure.

26.2.15 7632 PID 1 fbk tune thr 1 perc FLOAT 0.10 0.00 10 RW VS
Autotuning is interrupted (error 25) if the feedback signal does not reach the set value (expressed as a per-
centage of full-scale) within three minutes after the start of the autotuning procedure.
Menu PAR Description UM Typo FB BIT Def Min Max Acc Mod
26.2.16 7634 PID 1 fbk tune thr 2 perc FLOAT 20.00 1.00 100.00 RW VS
The maximum value (expressed as a percentage of full-scale) that the feedback signal can reach during the
autotuning procedure. When the set value is reached, the PID output is reset and the autotuning procedure is
completed.
Menu PAR Description UM Typo FB BIT Def Min Max Acc Mod
26.2.17 7636 PID 1 ref autotune perc INT16 1 1 100 ERW VS
The digital reference value of the PID output for performing autotuning. The value is a percentage of the full
scale speed value (par
680 Full scale speed
).
Menu PAR Description UM Typo FB BIT Def Min Max Acc Mod
26.2.18 7638 PID 1 autotune BIT 0 0 1 RWZ VS
Enabling of the autotuning procedure: if this parameter is set to 1 the PID 1 controller autotuning procedure is
launched.
